Better thermal performance per mm Both EPS and XPS systems are designed to minimise water uptake, so there is no difference there, but Isoquick’s high performance EPS system has a better thermal performance per mm. Isoquick’s performance is about 15% better, (0.033W/mk v 0.037W/mk*). *These figures have been taken from 3rd party accredited documents. Typically, this means 250mm of Isoquick performs like 300mm of an XPS system. The thermal performance of the Isoquick boards will not degrade with time and is consistent whatever thickness of board you need. Isoquick locks together, guaranteeing performance Isoquick’s EPS system has been specially designed to lock together, meaning the modules can’t pull apart when the concrete is poured. This means the edge profile can’t have any gaps in it which would affect performance. We also use two layers of boars which interlock and overlap. This makes gaps between the base boards impossible, guaranteeing performance. Ready-made edge profiles All Isoquick edge profiles come ready-made for your site. This makes them robust and quick to install. We estimate each of your slabs would take half a day to install, allowing you to get on with the rest of your project. No additional support needed Isoquick edge profiles do not require additional support during the concrete pour. They are tested to carry more than 4x the load that would be created by the wet concrete. This means you don’t have to worry about the time and cost of adding extra support after the pour.
Our customers John and Annie have just finished the groundworks stage of their new family home in Yorkshire, installing an ISOQUICK foundation to the highest specificati on we offer with a 300mm thickness and U Value of 0.09. When finished, the house will be a two-storey, four-bedroom house and will be home to them and their three children aged 5 to 9. At the beginning their project, John and Annie had two priorities: that it must be an eco-house, and it must be comfortable. They first came across the Passivhaus standard when looking into eco building methods and quickly found that they wouldn’t be able to achieve the standard by just renovating their existing house. With professional advice being to demolish and start from scratch that’s exactly what they decided to do. They then found an architect to help them realise their dream, and chose one who is such a Passivhaus advocate it’s the only type of house he now builds. “We chose ISOQUICK as it was recommended by our architect who we trusted. He has used it many times before and found it the best system. It is really important to us that we achieve Passivhaus certification.” For John and Annie, building to Passivhaus Standards is a no-brainer: “Why wouldn't you build a passive house?! We are in a climate crisis and we can't believe there aren't more in the UK and that all new houses don't have to be to this standard.” To fit their budget, they did have to compromise on the house’s size but aren’t worried about it: “We were happy to have a slightly smaller house (because it is more expensive) but for it to be really energy efficient with no cold/drafty spots - so the whole house is useable space. No corners where you don't want to sit therefore no wasted space.” When asked about whether they had any trouble with planning approval or getting their builder on board with a non-traditional foundation, they said: “Planning is always hard but I think they were very welcoming towards certified passive house and gave as much leeway as they could. And from the start, our builder has been willing to work differently and was happy to follow much more detailed drawings and work to higher standards than are common in the industry. They are just as interested in the process as we are and hopefully will be able to do more similar work in future. The use of several specialist subcontractors, like Build Homes Better/ISOQUICK, also helped persuade him he wasn't exposed to too much risk himself.“ Speaking about the ISOQUICK install, John and Annie said “it went really smoothly and easily - it was fantastic to watch. You were very organised and experienced.” Thank you to John and Annie for speaking to us about their experience so far and we expect to follow up with them again in 2024 after their house is finished to find out how it is to live in their ISOQUICK Passivhaus.

Last week our General Manager Jonathon Barnett was at the BRE Innovation Park overseeing the installation of the ISOQUICK® foundation for Collida Living’s Passivhaus Plus show home. The show home is part of a big investment into off-site manufacturing by Willmott Dixon who created Collida Living to develop a new generation of sustainable homes that enable local authorities, registered providers and developers to respond to the climate emergency and meet the UK’s net zero commitments. Once finished, the show home will be Passivhaus Plus certified and net-zero energy on-site. This is an exciting project for the future of home building and we are proud that ISOQUICK® was chosen as the foundation. Thanks to Tom for his feedback. "I just wanted to say a huge thank you for coming down to site yesterday to assist in the install of the ISOQUICK system. It is a very impressive system indeed! I think everyone who saw it yesterday was blown away with how easy and quick it was to install with pretty much 0% waste." Tom Armstrong-Jones Building Manager, Willmott Dixon
Built using ISOQUICK® and combining all the benefits of ISOQUICK® with modular construction, the Foleshill Health Centre in Coventry has been designed to cater for an expected 10,000 patients. The building’s Passivhaus design is predicted to save the NHS approximately £450,000 in operating costs over 25 years following construction.
