Attic Insulation Antrim

Why do we use a breathable vent card?
A 50mm air gap between insulation material and roofing felt is required by Irish building regulations to allow water vapour excape your building. After extensive research we developed our unique vent card, designed to fit exactly 50mm from your foofing felt, it is rigid, not loosing it form over time yet permeable allowing your timbers to breath.
