Openings in ceilings for downlights and spotlights represent an easy path for air leakage and draft. TENMAT Loft Covers solve this problem.




Typically 25% of house hold energy wastage is lost through air leakage. Downlights are the source of a high proportion of air leakage in the home, each downlight can typically pass 20 cubic metres of conditioned air from the house into the ceiling space per hour at 50pa pressure and this air and energy is lost. The fitting of TENMAT Loft Covers dramatically reduces the volume of air leakage through each downlight and in fact at normal pressures totally negates it, therefore reducing draughts and energy loss.
