Double glazed windows or doors are uPVC frames fitted with two panes of glass with a space
between them. The glass unit is sealed to be airtight and fitted into the uPVC frame. The idea behind
double glazing is that two panes of glass, plus the air gap between them, act as a layer of insulation
inhibiting the passage of heat or cold from outside into your home, thus making it energy efficient.
Double glazing reduces heat loss by approximately 60%. Our uPVC door frames combined with
double glazing make a good combination. Double glazing also insulates against outside noise and
makes your rooms more quiet and peaceful.
