What Our Customers Say


Professional :

“We have been really pleased with the system since we installed it. As we constructed our Passivhaus home ourselves we wanted a system that would be compatible with the rest of the high performance timber frame and we found that in Isoquick. Our home is a pleasure to live in, and despite having no under floor heating the exposed concrete slab that sits within the Isoquick always feels comfortable to touch.


We chose the Isoquick system over others because it didn't require any shoring (additional support) during construction, and because it came pre-cut to size so no further adjustments were needed between installation and the next stage of the build. This improved the time-scale on site and lead to a more seamless process.”

“We’ve needed a lot of support, before and since". Isoquick "arranged for the slab engineering, I’ve had questions about the thresholds, protecting the EPS, etc. I couldn’t be more grateful for the help.

You both have been absolutely terrific. Isoquick in the group of the most solid, reliable, helpful people and suppliers for this project so far. We wouldn’t be where we are without you."

"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."

Excellent product; we went for the value install and Jonathon did all the tricky bits and between my wife and I we did the fill in. They are very knowledgeable, helpful and with lots of experience.                        All in all a first class experience.

“Using an insulated raft foundation saves time and saves organising the extra trades that you need for a conventional foundation”

“The technical advice and onsite support are the reasons I will make Isoquick my first choice for future floor slab insulation requirements. They come with my strongest recommendation”

 BAM Construction Ltd


Self Builder :

“Thank you for that. It was a good day’s work and it certainly illustrates well the merits of Isoquick. I have a friend who is building a similar house to ours but opted for a slightly less expensive footing – and is now greatly regretting it…! Likely to end up actually more expensive!!

"We have done several Isoquick projects now and are completely sold on it"

Professional :

“We chose Isoquick as it is pre-cut to the right shape and individual pieces interlock for greater stability. Building with Isoquick is simple, it’s like building with LEGO.”
