PVC improvement you can’t see, till you get your heating bill!
Riding the e-Wave of improving insulation and energy efficiency, Profel has developed a new PVC profile for windows and doors without compromising on strength, and including recycled materials to do it.
Profel was able to combine the thermal insulation properties of plastic and the stiffness of steel in a new type of reinforcement profile for manufacturing large-size PVC windows and doors with high thermal insulating properties and high stability.
The widely applied steel reinforcement is replaced by a thermal interrupted profile. This is achieved by constructing a reinforcement profile with a PVC soul and steel flanges.
PVC soul, you ask? Why not? After all, the Beatles’ album ‘’Rubber Soul’’ was groundbreaking.
Thanks to that PVC soul and steel flanges, Profel came up with a completely new product by simply changing the profile shapes and coating the galvanized steel with Plastisol to improve adhesion with PVC.
A new element is introduced between the two steel flanges to create the thermal bridge. This is a hollow profile or a full hard foam profile made of recycled PVC.
Completely new is the assembling module of the new reinforcement profile: the steel flanges and the PVC web profile. The assembly module for the reinforcement profile is an online machine using a system of gluing or fusing to give a rigid bonding of the two PVC coated steel profiles and PVC web profile.
The resulting reinforcement system gives a reduction of the heat transmission factors from Uf = 1.47 W/m²K to a Uf = 1.15 W/m²K and this without loss of mechanical properties. Contrary to other new window systems, this one doesn’t need any special composites or assembling of glass by gluing to maintain its global performance.
Bottom line, Profel has succeeded in creating a product with better insulation, lower energy emission, and contributing to environmental efforts by using recycled material.
