Double Glazing.
Double
glazing involves two layers of
glass
with a small air gap between
them.
It works as an insulator in much the
same way
as cavity wall
and loft
insulation.
The air
gap is too small to allow the
air to circulate.
This prevents heat transfer by convection.
The trapped air is a very
poor conductor
which reduces heat loss through the
window.
The room in the house stays warmer
for longer (see costs).
Double
glazing is a good barrier to sound
and can help reduce unwanted
noise.
