How to identify energy efficient bi-fold doors

Bi-fold doors are increasing in popularity, with the market expected to grow by 7% year on year. Their aesthetically pleasing modern design lightens up a room, creating an enviable inside and outside space. The installation of bi-folds also has the power to increase a property’s value by as much as 10% – it’s no surprise they’re so sought after! While bi-fold doors are a sleek home addition, with the average large format doors filling an aperture of over 3.5m wider and 2.1m high, product quality and air tightness are incredibly important. It is recommended to review the doors energy efficiency before purchasing. Less energy efficient models that let in a draught will let heat out of a property and won’t be as protective of the interior.

Here’s what you should look out for in order to identify an energy efficient bi-fold door system:

  1. U-values

The U-value measures how effective a material is as an insulator. As a rule, the lower the U-value, the more efficient the material and therefore, the lower the annual energy bill will be. With bi-folding doors you generally want a value of 1.4 or less to ensure that you have optimal thermal performance. There are a variety of energy efficient bi-folding doors, with low U-values, such as bi folding doors from Quickslide.

  • Weather Testing

A suitable weather resistant bi-folding door should have been rigorously tested to ensure they are watertight and remain protected against an array of weather conditions. Bi-fold doors are subject to a weathertightness test, more formally known as a BS6375 Part 1. This assesses the air permeability (varying levels of air pressure are applied to the material, testing the amount of air leakage), water tightness (water is sprayed at varying pressures to see at what point it starts to penetrate) and wind resistance (varying levels of wind pressure are applied to see what the maximum resistance levels are). When purchasing a bi-folding door, make sure to check the exact model has undertaken a weathertightness test. This will offer homeowners peace of mind that the doors will keep their home fully insulated from all weather conditions.

  • CE Marking

CE Marking is a legal requirement for products sold in the European Economic Area. It is mandatory for all UK manufactured bi-folding doors to be CE marked. For a product to receive this accreditation, the manufacturer must present evidence under a series of categories, including thermal efficiency and weathertightness. Therefore, you can rest assure that any door you are purchasing with this marking, will be compliant with required performance characteristics, in line with UK requirements, such as weathertightness and thermal.

  • Polymide Thermal Barrier

Aluminium is a natural conductor, so to improve the insulation of the door frame, they can be upgraded to include polymide thermal barrier technology. Aluminium bi-folding doors that have been upgraded to this technology over old resin thermal barrier give at least a 30% improvement to thermal efficiency. The advanced profile technology creates a thermal transmittance barrier between the cold outside and the warm inside. This works to thermally secure the home, keeping it warm in the winter months, and reducing the energy bills.

Considerate Constructors Scheme expands to offer registration to professional services

Professional service organisations can now demonstrate their considerate credentials

20 May 2019: The Considerate Constructors Scheme – the organisation established to improve the image of construction – has expanded to offer professional service organisations the opportunity to register with the Scheme.

Eligible organisations providing professional services to the construction industry, such as architects, engineering consultancies, surveyors, accountants and lawyers, are now able to join the 7,000 plus construction sites, companies, suppliers and clients of construction projects who register with the Scheme each year.

Professional services account for around 11% (£186 billion) of the UK’s Gross Value Added and employ around 13% (4.6 million) of the UK’s population.*

This exciting development comes at the request of those already registered with the Scheme to ensure their entire supply chain is part of the Scheme, as well as an increasing number of professional service organisations wishing to be part of the Scheme to help improve their standards in considerate construction.

Edward Hardy, Chief Executive of the Considerate Constructors Scheme said: “We are delighted to welcome eligible professional service organisations to the Scheme. This is a significant development for our entire construction industry, as professional services form an integral part of the industry’s supply chain.

“The impact such organisations can have in becoming part of the Considerate Constructors Scheme to improve their standards will no doubt have a significant influence on improving the overall image of our industry.”

Industry reactive: the steel industry could make 24,000 workers redundant

Following the news that the steel industry in the UK needs to find a £30m cash injection or it’s likely to face administration, potentially affecting 24,000 jobs through Scunthorpe steelworks and its supply chain, Dilusha Hettiralalage, Consumer Savings Expert at, commented:

“The issues with the steel industry have been well documented since 2017 and in all honesty it’s done well to continue on for as long as it has. It’s a significant part of UK heritage and industrialisation, and it’s hard to imagine a UK without British Steel, but right now we need to be thinking about the 24,000 workers who could be left jobless if the second-largest steel producer in the UK is to close its doors.

“Our hearts are with those right now in limbo, unsure of what is happening and if they will have a job by the end of the week. Whether they’re single, married, have children or don’t, it’s never ideal to lose your job – especially ahead of the summer holidays, a notoriously expensive time of the year. One must also appreciate the fact that many steel workers have been operating in the industry since leaving school as teenagers, and have built up a very specific and niche set of skills that aren’t transferable to many other job roles if they are made redundant.

“£45m has already been injected into British Steel from shareholder Greybull Capital, so whilst things are looking positive, will this be the last time that the industry faces this issue and jobs are put on the line? It’s doubtful. We wouldn’t recommend everyone jumps ship if the company is able to be saved this week, but maybe it’s time for workers to consider branching out and learning a new trade or transferable skills so that they are as employable as possible, should they find themselves without a job.”

Best Regions for Construction Startups

1. North East

  • Regionally, the North East has the smallest percentage of construction companies (15%).
  • Just 6% of the region are employed in this sector – which is 2% lower than the national average.
  • But despite the North East’s construction industry being much smaller than other regions, it shares 12% of the area’s turnover across all industries.
  • From a wider outlook, it also contributes 3% to the British construction turnover – showing the area it has plenty of room to grow, too.

2. Scotland

  • Construction only accounts for 16% of the area’s turnover across all industries – which is 2% lower than the UK average.
  • More construction workers are also needed to address Scotland’s housing shortage, which means there is little competition.
  • Official figures from the Scottish government show that the economy grew by 1.3% in 2018, which proves that there is profit potential.

London office work shifts towards major refurb projects

The construction of new offices in central London is at its highest level in three years with 37 schemes breaking ground in the last six months.

According to the latest Deloitte crane survey the office sector is remaining resilient despite Brexit uncertainty with 3.5m sq ft started over the period, 38% up on the previous survey last autumn.

Overall new build figures were significantly boosted by four new starts at King’s Cross – including Facebook’s new HQ – representing nearly 1m sq ft of all new starts.

The biggest sector of the London market, the Square Mile, has started to see a pronounced shift towards large-scale office refurbishment. Over this period developers began work on eight refurbishments, which will deliver 800,000 sq ft of Grade A space.

The survey also highlighted some concern that the longer term forecast office pipeline of 30m sq ft, is nearly a quarter down over the last two years.

The latest biannual survey recorded 13.2m sq ft of office space now under construction – a 12% increase on the previous survey.

Mike Cracknell, director at Deloitte Real Estate, said: “London’s office market remains resilient in the face of uncertainty as we witness an encouraging increase in new construction starts. This is testament to developers’ continued confidence in London’s office leasing market long-term.”

He added that the uptick in construction activity in the run-up to the originally scheduled EU departure date of March 2019 was remarkable, given the magnitude of political and economic uncertainty.

He said that it demonstrated that developers had not delayed their construction plans and had confidence in the London leasing market over the long term.

The City of London continued to dominate construction activity with 6.7m sq ft across 33 schemes representing half of total volume under construction across the capital.

Among the top concerns for landlords and developers, Brexit uncertainty was cited by around a quarter. But longer term issues of ‘lack of development sites’ (32%) and ‘construction costs’ (32%), were the top two challenges for landlords.

Among key package contractors, most firms expected to see a little increase in work over the next 12 months, although the strength of positive sentiment has waned with the exception of external works firms.

The results around price sentiment in the Q1 2019 survey suggest an average 3% rise in prices over the next 12 months – similar to the figure reported in the Q3 2018 survey.

The exception was in demolition where significant price increases are being forecast.

Payment periods are on the increase from main contractors, suggesting harder times ahead. Payments within 30 days fell from over 40% to less than 30% of the total.

Essential e-learning launched to beat construction-related occupational cancers

New course to help construction workforce spot dangers and mitigate risks of developing occupational cancers

The Considerate Constructors Scheme has announced a new e-learning course ‘Occupational Cancers‘, designed to help the construction industry’s workforce to improve its understanding of occupational cancer risks and how to mitigate them.

With 40% of all deaths from occupational cancers arising within the construction industry, the need to support the workforce in this area has never been so critical.

The main causes of occupational cancers in construction work are exposure to silica dust, asbestos, diesel exhaust emissions and UV radiation, with those working in construction:

  • 100 times more likely to die from an occupational disease than a workplace accident (BOHS, 2016)
  • 6 times more likely to develop skin cancer than the general population (HSE, 2018)
  • Dying by cancers caused by silica dust – over 500 workers a year (HSE, 2005)

The ‘Occupational Cancers’ e-learning module is made freely available to the entire construction industry via the Scheme’s Best Practice Hub. It follows the successful series of e-learning courses on other cross-industry issues, including Air Pollution, Drugs and Alcohol and Mental Health.

The Scheme’s e-learning courses have received unprecedented engagement, with over 53,000 people working in construction taking the courses so far.

Edward Hardy, Chief Executive of the Considerate Constructors Scheme said: “There is no doubt that the shocking number of deaths and long-term illnesses caused by significant exposure to carcinogens in the workplace needs greater attention by everyone. We must continue to improve our standards in how we raise awareness and understanding of the risks and how to take measures to, where possible eliminate them, or at the very least minimise them.

“We call on everyone across our industry to take the ‘Occupational Cancers‘ course and to encourage colleagues, friends and family members to do the same.

“The Hub also features the ‘Spotlight on…occupational cancers‘ campaign which provides excellent examples of best practice in tackling this issue provided by construction sites, companies and suppliers to the industry across the length and breadth of the UK and Ireland. We anticipate more examples of best practice being shared across the coming months in order to drastically reduce the impact of carcinogens on our workforce.”

Lesley McLeod, CEO, The Association for Project Safety

“Safety needs to be built in so, while the government’s commitment to additional funding to replace high-rise cladding is welcome, it is better sense to tackle construction risks at the outset. The Association for Project Safety (APS) believes it is vital everyone who lives in a high-rise home can be confident they are safe so safety must be the priority right from the planning stage.

“Safety is at the core of good design and the APS remains committed to working with the government and other professionals in the construction sector to promote and share good practice, as well as making sure everyone can build the skills and knowledge, they need to make Britain’s building better.

“The APS welcomes the use of public funds to make high rise buildings safer, but we are concerned the timetable is very tight and that funds may prove insufficient – we believe it is better to do things right than force a potentially unrealistic deadline and budget on the project.”

Those Working In Construction Ninth Most Likely To Take Time Off Work For Their Mental Health

A recent UK study has revealed which sectors are the most likely to need to take time off work for their mental wellbeing, with healthcare topping the list (26%) followed by those working in the media (23%) and those working in education (21%).

This research into the mental wellbeing of Britons was conducted after the inventor of income protection discovered that 7% of all claims made in 2018 were related to mental health.

The team at conducted the research to find out how each sector was affected by absence relating to mental wellbeing. A total of 3,000 adults aged 18 and over from the UK, were quizzed as part of the study. Respondents were split evenly across 15 key sectors.

Initially, participants were asked, “Have you ever taken time off work for your mental health?” with the following emerging as the results for each sector:

  1. Healthcare – 26% (of employees have taken time off work for their mental wellbeing)
  2. Media – 23%
  3. Education – 21%
  4. Banking/Finance – 19%
  5. Public Sector – 17%
  6. HR/Personnel – 15%
  7. Retail – 13%
  8. Marketing – 12%
  9. Construction – 11%
  10. Transport/Travel – 9%

When asked to elaborate on the reason for their mental wellbeing-related absence from work, if they felt comfortable doing so, the vast majority blamed it on burnout/stress (68%).

Relevant respondents were found to have taken an average of three weeks off for their mental wellbeing; of which a third (34%) said they received their full pay during this time and 57% said they received reduced pay.

Of those who had suffered with their mental health, just 1 in 5 (21%) said that they had gone to speak to a professional about this, with those that didn’t citing long wait times (78%) and not knowing where to turn (20%) as reasons.

Finally, relevant participants were asked if they believed that their work had contributed to their poor mental health to which 9 in 10 (92%) said that they thought it had.

Georgia d’Esterre, Head of Marketing at, said:

“Looking after your mental health is often far harder than looking after your physical self. After finding that 1 in 14 of our claims last year were related to mental wellbeing, we wanted to see how each sector is affected by this growing crisis. With mental health services overstretched and employees having to work harder than ever before just to make ends meet, we need to remember to take the time to look after ourselves.

“The horrid thing is that money is often a massive cause for worry which can contribute to mental health issues. Having to take prolonged time off work can be scary in these situations as your pay is never guaranteed. This is a prime example of why more needs to be done to educate people on the importance of income protection.”

Experience ‘ground engineering’ in virtual reality with Aarsleff this Summer

This summer, Aarsleff Ground Engineering are inviting their valued clients to experience the virtual world of ground engineering at their Head Offices in Newark, Nottinghamshire.

Guests will be shown to the company’s VROOM where they will be given a short tutorial before leaving reality and entering Aarsleff’s ‘virtual’ one.

Equipped with a state-of-the-art VR headset, user’s will be taken through a 6-minute guided tour around the ‘Aarsleff World’, exploring some of the company’s core specialist ground engineering techniques – both above and below ground. Traversing through Rail, Commercial, Residential, Mining and Industrial zones, the user will be able to take a closer look at rigs and machinery by leading innovators Junttan, Klemm and Movax and experience the ground engineering techniques that the Aarsleff organisation deliver on site every day.

Aarsleff teamed up with leading UK 3D technology and software development studio Luminous Group back in October 2018 to develop the virtual reality application, and have since developed a close working relationship with the organisation for the development of future digital initiatives.

The experience has been created using the latest Unity games engine and HTC Vive Pro headset providing full natural interaction with six degrees of freedom and high-quality visuals. Users can view a mini table top view of the Aarsleff world or fly down to see interactive cut always of the ground below. Games engines with their real time rendering capabilities and ability to port content to multiple devices and platforms are becoming the preferred choice for creating interactive computer graphics, VR experiences and visual effects.

Aarsleff’s Marketing and Communications Manager said: “Finding ways to visualise and engage with ground engineering techniques can be challenging – everything our specialist industry does is underground or soon covered up. The new virtual reality application makes it possible for our users to experience ground engineering techniques in a more dynamic and accessible way than ever before, and this is what makes it really unique”.

With half a million workers set to retire over the next 10 years, the application has primarily been designed to address the growing skills shortage in the construction sector with a view to help attract the next generation of digitally native gamers into the industry. The application has been designed to both appeal to a new entrant into the field of construction, and an already established geotechnical engineer who would like to understand more about Aarsleff’s products and services including Drilling and Grouting, Soil Nails, Driven Piling, Mini Piling and Sheet Piling.

Managing Director Kevin Hague said: “In embracing VR, we also hope to tackle the challenge that ‘young people are not interested in construction’ by rolling out the virtual application at careers fairs and university shows. Students and aspiring engineers will be able to walk around on an Aarsleff site, helping them to understand several ground engineering disciplines and learn about the machinery operated on site – all whilst in a safe and engaging way”.

The Newark-based specialist contractor are exclusively inviting a selection of clients to their offices to experience their new VR application over the summer period, after which point the program will then be exhibited at careers fairs and shows and for all other interested parties to experience on a pre-booked basis.

How to solve the Quantity Surveyor Crisis?

There’s been some alarming titles in the press for more than a decade now: “A global crisis of the surveying profession” (2008), “Surveyor skill shortage approaching critical level, warns RICS” (2015), “Easier to employ a ballet dancer than a quantity surveyor” (2017)…

The latest CIOB-cross industry research report published in January 2019 highlights that the issue is far from being solved, with 42% of construction businesses reporting difficulties recruiting quantity surveyors, both now and by anticipation, post-Brexit.

The RICS Construction and Infrastructure survey of Q1 2019 also confirms that quantity surveying is still the occupation with the greatest staff shortages, beyond trades, bricklayers and other construction professionals, with 60% of companies reporting skill shortages in the profession.

Why are there shortages of quantity surveyors?

The construction sector in general is experiencing an ageing working population, with nearly 430,000 construction workers to retire between 2010 and 2020. More specifically, the quantity surveying profession experiences difficulties attracting young students, due to the complexity of the role and the lack of clarity on the definition of the profession.

While a problem not limited to the UK, the uncertainties surrounding Brexit are enhancing this issue. As 26% of the UK construction workforce comes from the EU, the deterioration of the sterling makes the country less attractive as a work destination. Construction material costs inflation also leads to a greater need for complex cost estimates (and great quality quantity surveyors!).

What are the solutions to address the quantity surveyor crisis?

The government is looking at increasing the attractiveness of the profession, promoting apprenticeships and easing the barriers to immigration as different solutions to address this challenge. One of the recommendations of the CIOB-cross industry research report is to include the quantity surveyor profession to the future “Shortage Occupation List” of the Migration Advisory Committee.

As a construction business owner, there are three routes to explore to find quantity surveyors.

Take on apprentices

23,000 apprenticeships started in England in Construction, Planning and the Built Environment in 2017/18. Taking on apprentices can be a really great way to attract young professionals, especially as quantity surveying apprenticeships are fairly quick to obtain – from 2 years for a Surveying or Geospatial Survey Technician apprentice (Level 3) up to 5 years for a Chartered Surveyor Apprentice or Geospatial Mapping and Sciences Apprentice (Level 6).

The latest apprenticeship data from the Department of Education in January 2019 shows that only 9 people started an apprenticeship as a Geospatial Survey Technician since 2015/16, 506 as Surveying Technicians, and 1,892 as Chartered Surveyor Apprentices – there’s still room for many more!

Look for temporary contractors

Rather than desperately trying to recruit permanent quantity surveyors, recruiting contractors from temporary recruitment agencies can be a way to avoid turning down projects. While this route is typically more expensive than recruiting permanent members of staff, it can be a great way to release the pressure and gain flexibility. It might also lead some contractors to convert to permanent positions in the future.

Leverage technology

Becoming familiar with 3D modelling packages and BIM (Building Information Modelling) software (e.g., Estimator360, HBXL, PlanSwift, Clear Estimates…) to price projects can be another way to fix the crisis. While the barrier to entry can be high in terms of cost, digital skills required, and time required to select, implement and be trained on how to use estimating software packages, it can also be a great way to make the profession more attractive to younger generations too.

Whilst the crisis will not be solved overnight, there are some solutions out there to explore to help you address this challenge now.
