1. Energy Conservation within walls

2. Energy conservation Energy cannot be created or destroyed but can simply be changed from one form to another. The more energy which we use to heat our home the more green house gases which we add to the atmosphere. As a result government is directing us ( through the Building Regulations) to increase the amount of insulation within the walls of our homes and factories. Walls are composed of two principal elements :- Walls (masonry or timber) Glass

3. Insulation in the cavity wall This cavity wall has been constructed in such a way that 60mm thick insulation is placed in the cavity against the internal skin. 60-100mm thick insulation 25mm thick insulation to prevent cold bridging at all window and door jambs. Insulation

4. Double Glazing Double glazing is where two sheets of glass are placed together in sealed units. The units are manufactured to special order and the two sheets of glass are hermetically bonded to a metal spacer section. The space between the glass contains dehydrated air which eliminates condensation between the glass. Sealed units can be manufactured from clear or tinted glass. Triple glazing works in a similar way but with addition of another sheet of glass. An additional filament may be added to the inside skin such as “K glass” which further reduces the heat loss out of the building.

5. Double Glazing Double glazing not only reduces the heat loss from within the building but it also reduces the amount of sound entering the building. Double glazed windows must have good draft excluders fitted. If double glazing is to work efficiently they should also be close fitting.
