Solar Panels - Things to Remember Before Going Off-Grid
Bricks and concrete are very good a keeping house strong and upright, but they tend not to be very good at keeping heat in. This was not so much of a problem in the past but in these days of environmental awareness and fluctuating energy prices, we all have to take steps to make our homes more energy efficient. Once you decide that you need to insulate your walls you have a choice between internal, cavity and external insulation. We focus on external thermal insulation because we believe it is technically the best system on the market. Simply put external insulation is just like putting a warming blanket around your home. We encase the outside of your property in a layer of insulation and finish it with your choice of colour and render.
The reason for doing that is to stop the 35%- 45% of your heating bill that is lost via the walls. By insulating the walls you can trap all that heat in the walls. By trapping all that heat you can cut your heating bills and play your part in saving the environment. Estimates by the British Energy Saving Trust suggest a saving of over 2 tonnes of carbon dioxide for a standard 3 bed semi detached house.
To insulate your home, attach a few layers to the outside of your house. First attach a layer of insulation. This can vary from expanded polystyrene to rockwool depending on the requirements. The insulation typically is fixed to the wall both chemically and mechanically I.E. glued and bolted to the wall. To protect the insulation from the effects of weathering we seal the outside with a fresh cement coloured render finish.
We are often asked about the payback periods for external wall insulation. This is difficult since the cost of insulation depends upon the size of the building. It is difficult to calculate average payback periods for solid wall insulation precisely, since the cost of insulation depends upon the size of the building, the energy savings resulting from the insulation (and the cost of energy), the level of insulation applied, the presence of other kinds of insulation already in the property and the availability of grants. Plus there have been many rumours about CO2 taxes on private dwellings that would also have a huge impact.
