Different insulation materials have different expiration dates, but all of our sustainable loft insulation products have extremely long lifespans. Lambswool, recycled plastic and multifoil loft insulation will last the entire lifespan of a household, which is why we offer guarantees based on the longevity of your York property.
60 years is the minimum expected lifespan for our loft insulation products, which may not be the sort of timeframe in which you can realistically plan for repairs and replacements, but either way, it’s handy to know!
