Energy Efficiency

Energy losses from downlights often account for 50% of the total thermal losses of a ceiling. The fitting of TENMAT Loft Covers negate almost all of these losses.




Ceiling insulation performance:

Typically 30% of a house hold energy wastage is lost through the ceiling. It is widely know that any gaps in ceiling insulation dramatically reduce the overall performance of the insulation, typically insulation performance is reduced by 50% is only 5% of the ceiling area is not fully insulated. The use of Tenmat loft covers allow the insulation to be continuous and uninterrupted over the whole area of the ceiling saving energy and carbon emissions.
