exact requirements for supply only or supply and installation.
The diagram above shows how much heat is lost through windows and doors in a modern day property. The red areas show prior to standard double glazing being installed. The right hand image shows the drastically lower levels of heat loss. Heritage and Period building will experience similar heat loss and installation of our Heritage Units expertly fitted in traditional, crafted wooden frames can have similar impact on heat loss.
We can recommend a joiner near you who will be able to assist with the frames, while we can supply and install the made to measure Westcountry Heritage glass units.
Spacer bars are an integral part of our Heritage units. They separate the two panes of glass and because we use Warm Edge spacer bars, condensation is virtually eliminated. All our Heritage units are available with Black or White Spacer bars.
The table below shows the some of the variations available within our Heritage units.
Heat loss from buildings is measured by U value and is expressed in W/mk2k.
The lower the U value the better the insulation provided by the relevant material.
For comparison, the U value for a typical pane of single glazing is 5.8W(m2k)
