The Enviro GRP Composite Door. Beautiful to look at and use, and unique to Enviro. An incredible combination of style and value for money.

Have a good look at the Enviro Composite Door and you’ll see that all doors are not made equal…

Our incredible Composite Door is a masterpiece of modern manufacturing. The materials used in the construction of the door have been individually tested to ensure long term performance.

The use of a triple seal coupled with an effective threshold ensures exceptional weather performance and combined with its solid polyurethane core, excellent energy insulation properties.

meshSecurity features include laminated glass, a multipoint locking system, dog bolt hinges, cylinder guard, tough polyurethane core, reinforced with unique steel mesh, all as standard with other features as options.

The specially formulated Glass Reinforced Polymer and thermoplastic skin materials have been developed to promote UV stability, high thermal shock and scratch resistance, providing an effective barrier for the door.

The Composite door surfaces are manufactured from Gel- Coated Glass Reinforced Plastics or from High Performing Thermoplastics. These skins are bonded to an internal frame which combines a BBA approved laminated engineered timber with a specially designed thermoplastic edge.

The core is a high-density polyurethane foam (CFC & HFC free, ozone depletion potential zero).

Unbeatable strength
