Wall System and Insurance in Ireland — What Your Insurer Will and Won't Cover
On this page
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.
