Alkreflex One

Alkreflex® One is a multi-layer radiant barrier; two layers of pure aluminium on both sides of an airbubble film core. Applied in combination with an aircavity of 20mm on both sides Alkreflex® One provides the most optimal insulationvalue by radiating the infrared heat. The relatively thin material and compact lightweight roll makes Alkreflex® One the ideal material for renovation purposes. Alkreflex® One is resistant to moisture and therefore commonly used as a solution for insulating various cold surfaces.

Applications

Alkreflex® One is used as a vapour barrier radiant foil in (cavity) walls, floors, on the warm side (mostly inside) of roofs, industrial buildings like warehouses, units, containers and caravans. Alkreflex® One is also extremely suitable as a radiation foil behind radiators, the insulation of crawling spaces or garage doors. 

Processing

Alkreflex® One needs to be installed with an air cavity of 20 mm on both sides for optimal insulation properties. In pitched roof constructions as an insulating layer we recommend to install Alkreflex® One on the inside (warm side) of the roof. Installed like this Alkreflex® One has a double function; radiating heat and as a barrier to moisture. Junctures and overlaps need to be sealed by applying VAST-R® Alumnium tape basic. Insulating the floor by securing Alkreflex® One on the underside of the floor beams with a mild ventilation between floor and foil. Applying Alkreflex® One as radiator foil by simply cutting the material to the right size and apply magnets or double sided tape.
