To
reduce the amount of thermal loss from the inside of your
property, all of our systems have been thermal simulated to
indicate the true thermal value. The aluminium in our
systems is thermally broken, all of our systems are double
glazed with Low-E glass and we have tested for water ingress
and air permeability.
The
thermal rating of a window or door is measured in U-Values,
the lower the U-Value the better the rating.
Many companies will give you a U-Value based on the center
pane value or the U-Value of the glass. This value will
always be lower than the actual value of the window or door.
Our
laminated timber door has a U-Value of 1.4 or A rated on an
energy chart, this is because timber is one of the most
thermally efficient materials used in the glazing industry,
Aluminium is not so efficient. Bear this in mind, as some
companies will tell you that their aluminium system has a
U-Value of 1.3 or, better than an A rating?
