Heat Insulation for Buildings.
What is Double Glazing?
Double
glazing involves two layers of
glass
with a small air gap between
them.
How does Double Glazing Work?
Double Glazing 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
the rate of heat loss through the
window.
The room in the house stays warmer
for longer (see costs).
Double
glazing is also a good barrier to sound
and can help reduce unwanted
noise.
