Wall System and Insurance in Ireland — What Your Insurer Will and Won't Cover
On this page
All mainstream wall systems are insurable. Timber frame and thatch may carry a small premium. Straw bale and hemp-lime are specialist.
All mainstream wall systems in Ireland (block, ICF, timber frame, SIPs, CLT) are insurable at standard rates. Timber frame may carry a small premium with some insurers (5–10% on the building insurance) due to perceived fire risk, but this is not universal and is reducing as timber frame becomes more common. Straw bale and hemp-lime are specialist systems; some insurers won't cover them, and those that do charge a significant premium. Get insurer confirmation before you specify a non-mainstream wall system. The structural warranty (HomeBond, Premier Guarantee) is a separate product from the building insurance and is mandatory for self-build mortgages.
When this matters most
