Improves duct and hvac system efficiency up to 50 increasing efficiency can lower cooling and heating costs reduces attic temperatures up to 30 degrees f in the summer 24 w x 125 length roll see more product details.
Reflective multi layer foil insulation.
Item 701987 model rdbw24100.
Additionally some multifoil insulation products have been combined with other features meaning that one product can be used for several functions.
Multi layer reflective foil insulation for roofs walls and floors.
A number of multi foil insulation products now come with vapour control layers whilst other multi foil insulation products can also act as a breather membrane or vapour permeable insulation.
Gfp is ideal for both thermal and acoustic applications and can add up to r13 with one layer and r22 with two.
If the product is simply doubled with no air space between the layers a very minimal benefit is obtained r 1 1 per layer for the reflective double bubble.
4 x 25 ft roll industrial strength commercial grade no tear radiant barrier wrap for weatherproofing attics windows garages rv s ducts more.
Fast and simple installation without any harmful fibres or particles.
4 6 out of 5 stars 100.
With multiple layers of product and airspaces between each layer enhanced performance will be gained.
If you install 2 layers of a reflective insulation does the r value double.
They have a high vapour resistance so may also function as a vapour control layer.
The reflective insulation systems available in fi foil s advanced family of products also include gfp insulation gas filled panel technology which contains low e baffled chambers filled with air argon and other inert gases.
Multi layer reflective foil insulation is recommended for use in a range of applications.
Their installation typically relying on the need for an adjoining cavity facing the surface reflective foil.
Made with aluminium for maximum thermal performance the reflective properties keep the living space warm in winter and cool in summer with effective solar over heating barrier.
Superior quality unique multi layer reflective insulation reduces emittance of radiant energy by 97 easy to install.
