Softwood Conservation Fret
For the more traditional finish to a window design, our new fret is the ideal solution. It has been used by many of our customers working in conservation areas. Sovereign Stormsure windows are now available with our Softwood Conservation Fret.
*Extended sill nosings can be vulnerable to damage and long-term erosion. If they are not adequately maintained, this could lead to premature failure of the decoration system.
Please be sure to specify the correct sill width to suit the brickwork detail, and to comply with Building Regulations Approved Document ‘L’.
