In a bid to remain faithful to its mantra, "Take control of your energy costs", Rigifoam 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.
LAMBDABOARD has the highest R-value per 25mm thickness, therefore the design U-value of the insulation system can be achieved with a minimum thickness. This in turn allows the overall footprint of the building to decrease and reduces the cost of construction.
