Did you know
25% of heat
is lost through the roof?
Poor airtightness sealing around loft stairs hatches can result in the ‘chimney effect’ where warm air is drawn up into an unheated loft space. The PHS Loft Stairs Insulation Kit is a triple action solution -providing airtight insulation, vapour control and a double radiant barrier reflecting back heat.
