Fakro XDP Under Felt Collar

Fakro XDP Under Felt Collar

The Fakro XDP Under Felt Collar is an insulation and breather membrane solution designed to connect compatible Fakro roof windows to the surrounding roof system. It helps provide effective insulation around the window frame, filling the space between the window and roof construction to support a more thermally efficient and weather-protected installation. The XDP Under Felt Collar & Insulation Set is designed to make insulating around roof windows easier and more efficient. By helping reduce thermal bridging, it supports improved insulation performance while creating a more complete connection between the roof window and the roof structure.

Natural Sheep Wool Insulation

The Fakro XDP insulation includes specially impregnated sheep wool, providing a natural and environmentally friendly insulation material. The wool is designed to be gentle on the skin, odour-free and non-irritating to the eyes, making it a practical material for installation work. Thanks to its elasticity, the insulation material can adapt to the spaces between the window frame and surrounding roof construction elements. It can also be easily cut and shaped during installation, helping installers achieve a close fit around the roof window for effective insulation.

Easy Installation and Thermal Performance

The XDP Under Felt Collar and insulation set helps simplify the process of insulating around a roof window. The flexible sheep wool material can be formed to fit the available space, helping fill gaps between the window and roof structure. When correctly installed, the insulation helps reduce thermal bridging and supports the thermal performance of the roof window installation. The breather membrane collar also provides a connection between the window and roof system, contributing to a more integrated installation.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
