Sub-sill & Reveal Fixing

• Sub-sill. Series 464 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 464 has a snap-in filler that allow us to secretly apply a second line of fixings as shown below.
