We source all our glazing units from A C Yule at Elgin and Aberdeen and our standard fitment is:
- 4mm clear or patterned glass outer pane
- 16mm or 20mm cavity with a warm edge spacer bar and argon gas fill.
- 4mm softcoat low-e inner pane.
This gives a centre pane u-value of 1.2 which we believe in most cases to be the best compromise between performance and cost. We can supply higher performing glazing units, but at increased cost, and are happy to discuss specific options and requirements. The pdf attachment shows a typical window u-value calculation.
As with all aspects of specification, we welcome visitors to our factory and showroom, both to view and discuss all the alternatives.
