Are Recticel Insulation's products environmentally friendly?
Our boards are an extremely efficient form of insulation and over the life of a building will save far more energy in their use than required in their production, resulting in significant reductions in energy consumption and cost, as well as reduced CO2 emissions.
Can electric cables be channelled into Recticel insulation boards?
No, as this would reduce the performance of the boards. Cables can penetrate the insulation with no detriment to the cable sheathing. Any cables penetrating or lying against insulation should be oversized to cater for increased operating temperature. If in doubt, consult a qualified electrician.
What is the difference between a U-value and an R-value?
U-values take into account all elements of a construction, including thermal bridges. They can only be worked out by calculation. The R-value, or thermal resistance, is a measure of the insulation board on its own, dividing the thickness (in metres) by the thermal conductivity (lambda value, W/m.K). The R-value can be used to compare how different thicknesses of products with different lambda values perform comparatively.
