Installation base XRD-A

When the roof pitch is too low to properly install the F or G type window, the XRD-A installation base is an excellent solution. This element increases the installation pitch by 3° or 5° (depending on the size), which allows for proper installation of the window and free drainage of water from the glass surface. The base’s structure is founded on four impregnated and painted wooden elements, which when assembled form a durable wedge. Installed directly beneath the window, it maintains the integrity and tightness of the entire structure. The product is fully compatible with XRD and XRD-W bases.
