& Reveal Fixing
- Sub-sill:
Series
452 windows come with integrated sub-sill fitted as
standard.
• The sub-sill is a secondary line of defence and is fitted with PVC front flap, covering the drainage holes.
• Has built in nailing fin to allow timber reveals to be fixed to sub-sill.
- Stop-ended:
To
complement the sub-sill installation we have also designed
injection moulded nylon end caps that nest into the
frame and sub-sill.
- Reveal Fixing: On wide window frames (102mm) it's desirable to get a second line of reveal fixings to keep the reveal tight up to the frame. Series 452 has a snap-in filler that allow us to secretly apply a second line of fixings as shown below.
