R-VALUE PERFORMANCE
LAMBDABOARD® has the highest R-Value per mm, therefore the design U-Value of the cavity wall system can be achieved with aminimum thickness of insulation. This in turn allows the overall carbon footprint of the building to be reduced.
MOISTURE RESISTANT
Although a cavity wall is not designed as a wet environment, a cavity wall performs by taking the small amount of water penetrating the outer way the, draining it down the cavity face of the outer wythe to a flashing which directs the water back to the exterior. LAMBDABOARD® has a less than 3% water absorption and is the perfect choice for this environment. Refer to moisture test SABS 1381-1.
EXCELLENT DIMENSIONAL STABILITY
Temperature cycling and humidity encountered in cavity wall applications does not affect LAMBDABOARD® thermal performance.
