Karnak 298 Alumin-R is manufactured from SBS rubber modified asphalt combined with a specially designed aluminium pigment to act as a single-apply rubberised reflective coating. This product is applied in just one coat, lasting up to 3 times longer than other traditional coatings on the market. Karnak Alumin-R can be used to refurbish old roofs, whilst reducing roof temperature thanks to highly reflective properties. Compatible with modified bitumen membranes, felt, prepared metal surfaces and sloped residential concrete roofs, this tin offers around 7 square meters of coverage with one coat offering 1 square meter per ½ litre. Karnak 298 Alumin-R has 300% elasticity, meaning it’s more resistant to moving and cracking on a roof, contributing to its 10-year plus life expectancy.
