I have Steel 1930's casement windows. the front of the house (East facing) are single glazed (4mm?). The rear (West facing) had already been upgraded to double glazing (looks like 4-6-4mm).
I am considering upgrading the glass on the front of the house.
How much of a difference will it make / is it cost effective for improving the insulation of the house?
What glass is recommended, where is the value point in terms of spec? .e. argon filled/low E, etc
Thanks.
Looking at the Pilkington tables the existing windows would be c4.8 U value. And new 6mm double glazing would be 2.3-3.1 U.
