Frequently Asked Questions

Everything you need to know before getting started with your ISOQUICK® foundation.

Can I really install this myself?

Absolutely. We provide hands-on installation support with every project. Our experienced team works alongside you on site, bringing the right tools and expertise to guide you through every step. Most self-builders are genuinely surprised how straightforward the process is — we'll make sure you get it right.

What installation support is included?

Every self-build installation is fully supported. Our experienced team works alongside you on site, bringing the right tools and practical expertise to guide the ISOQUICK® assembly. The programme depends on the size and complexity of the project, site conditions and the structural engineer's reinforcement design.

What's included in the free design advice?

We review your architectural plans and proposed construction details, then advise on the ISOQUICK® layout, U-values, wall-system compatibility and relevant ground-condition considerations. Standard Psi-values for typical wall build-ups are available free of charge. Bespoke Psi-value calculations are available as a paid service, with the fee redeemable against an ISOQUICK order. A qualified structural engineer appointed to your project must design and approve the slab, reinforcement and other structural elements.

Will this work with my timber frame / SIPs / masonry build?

Yes — ISOQUICK® is compatible with all common wall systems. We specify the correct junction details and thermal breaks for your exact build-up, ensuring there are no cold bridge problems. Whether you're building with timber frame, SIPs, ICF, or traditional masonry, we have a solution.

How do I get started?

Simply request a callback and we'll arrange a time to discuss your project. Once we have your plans, we'll provide free design advice and a detailed quote within a few working days. There's no pressure and no commitment.
