  • Ultimately, this maintains the character of unique, stylised buildings from the outside while simultaneously creating a comfortable, modern interior.
  • Most of our standard windows are available in this version, including: centre pivot, preSelect, roof access and raised axis windows.
  • Conservation windows are manufactured in P2 and P5 as standard glazing options but other glazing types can be requested.

Three of these conservation options (the FTP and FTW) come complete as a kit with flashing and insulation collars. There are two choices when selecting a kit: ‘V’ and ‘J’. These indicate varying levels at which the roof window can be installed within the roof structure. For example, when choosing a flashing to lift the window by 3cm from the standard ‘V’ level, the N variations will be suitable. On the other hand, ‘V’ is a standard installation level whereas ‘J’ is recessed – 3cm below the ‘N’ level.
