As a major partner in complementary profiles for joinery, Geplast has a complete range of trim profiles compatible with all products on the market.
Joinery profiles are essential for creating openings that will last over time. They are designed with thermal performance, water and air tightness and weather resistance in mind.
Aware of the importance of reducing its environmental footprint, Geplast offers cladding profiles that meet the challenges of the RE2020.
- The primary objective is to reduce the carbon impact of construction by using bio-sourced or recycled materials. At Geplast, 95% of angles, flats and flaps are produced using co-extrusion. More specifically, the profile is composed of an under-layer of recycled PVC which is covered by a layer of un-recycled PVC in order to maintain the technical performance of the PVC.
- The second priority is to improve the energy performance of buildings by making them more energy-efficient and improving indoor summer comfort. This means replacing old joinery with new, more efficient units.
Fitting joinery for renovation
When renovating, there are two ways to change your joinery.
Partial removal – with preservation of the existing frames
Total removal is one of the most advantageous solutions for renovation. It provides maximum daylight and perfect airtightness, and is virtually identical to new-build installation.
Geplast has therefore developed a universal system that optimises on-site installation and limits heat loss. The width of the moulding makes it possible to insulate between the joinery and the masonry and to create an angle groove on a new external or internal frame. Installation complies with DTU 36-5.
