LAMBDABOARD is a flexible-faced Polyisocyanurate (PIR) insulation board. We offer you the best possible solution for your insulation requirement compared to similar products in the market. In a bid to remain faithful to its mantra, "Take control of your energy costs", Rigifoam/Lambdaboard recently renewed its commitment to the supply of insulation capable of reducing operational heating and cooling costs resulting in positive environmental and climate change consequences. Its launch product, LAMBDABOARD, is a unique solution to the current energy crisis. With the highest R-value per 25mm thickness, the design U-value of the insulation system can be achieved with a minimum thickness. This, in turn, decreases the overall footprint of the building and reduces the cost of construction. Installing Lambdaboard will positively impact the HAVC system required, reducing the requirements for over-engineered systems, thus affecting the energy consumption needed to run the HAVC system. Putting money back in your pocket. Did you know Lambdaboard provides 30% saving on energy consumption. And that 70% of heat loss can be found in the roof of a structure. Lambdaboard can reduce this by 100% so that no heat is lost via the roof structure.
