APS stock thermal inserts to suit pvc window and door outer frames, sashes and mullions.
Why use thermal inserts?
- Thermal inserts improve thermal efficiency for white and brown substrate products.
- They achieve an ‘A’ rated window using ordinary float glass on outside pane.
- There is minimal disruption as they are inserted into profile before it is cut and welded.
- Stronger welds are possible - maximum sash sizes achieve BS 6375 Part 1 and Part 2 – gusting to 1600PA for espagnolette locks and 2000PA for shootbolts.
- More competitively priced than galvanised steel reinforcing
