Why do you recommend Insulation Boards on a concrete base?


The insulation boards are used to prevent heat escaping downwards to the subfloor, improving the efficiency of the system. Insulation boards can reduce running costs by as much as 50% because they are a highly efficient thermal barrier to cold rising from the subfloor. By reflecting the heat upwards instead of losing heat to the […]

What does R Value mean ?


The R value is a measure of thermal resistance used in the construction industry. The higher the R value the better an insulator (e.g. 10mm Warmup® Insulation Boards have an R value of 0.28 m²K/W and the 20mm Warmup® Insulation Boards have an R value of 0.58 m²K/W). All buildings should strive for the highest […]
