Product Description

The Pitchglaze Mk. II is an in-plane roof window ideal for pitched tiled roof applications between 15 and 60 degrees.

The Pitchglaze is a UKCA and CE marked fixed glazing system designed to be installed between 15 and 60 degrees at least 800mm above floor level. Our latest version benefits from an all new fully extruded frame with incredibly tight tolerances, resulting in an outstanding fit and finish.

It features a Qualicoat approved polyester powder coated aluminium frame and is available from stock in our two most popular sizes. The Pitchglaze roof window adopts a pioneering ‘frameless’ design ethos, so that when installed, building occupants can enjoy sky only views, something not usually found with traditional roof window products.

The glass specification is high performance thermally efficient low emissivity (low e) coated glass which has been heat soak tested for additional safety. Based on the current design, aperture sizes of up to 3 metres squared are achievable.
