How does trade loft insulation work?

For new dwellings and extensions, the insulation has to match the design that achieved compliance, so we work from your SAP or U-value calculation and the specified product. We can install between and over the ceiling ties, fit eaves ventilation trays and loft hatches, and leave a boarded access route to services. More about trade loft insulation.
