Insulation Systems For External Walls - A Simple Introduction
Bricks and concrete are very good a keeping home powerful and upright, but they tend not to be extremely good at maintaining heat in. This was not so much of a problem in the previous but in these days of environmental awareness and fluctuating energy prices, we all have to take steps to make our houses much more power effective. As soon as you determine that you require to insulate your walls you have a choice between internal, cavity and external insulation.
We focus on external thermal insulation simply because we think it is technically the best method on the market. Merely put external insulation is just like placing a warming blanket about your home. We encase the outside of your property in a layer of insulation and finish it with your option of colour and render.
The purpose for performing that is to quit the 35%- 45% of your heating bill that is lost by way of 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 recommend a saving of over two tonnes of carbon dioxide for a regular three bed semi detached home.
To insulate your home, attach a couple of layers to the outside of your home. Initial attach a layer of insulation. This can differ from expanded polystyrene to rockwool based on the specifications. The insulation usually is fixed to the wall each chemically and mechanically I.E. glued and bolted to the wall. To protect the insulation from the effects of weathering we seal the outdoors with a fresh cement coloured render finish.
We are frequently asked about the payback periods for external wall insulation. This is difficult since the price of insulation depends upon the size of the building. It is difficult to calculate typical payback periods for solid wall insulation precisely, because the cost of insulation depends upon the size of the building, the power savings resulting from the insulation (and the price of power), the level of insulation applied, the presence of other sorts of insulation currently in the home and the availability of grants. Plus there have been many rumours about CO2 taxes on private dwellings that would also have a massive impact.
Quoted payback times are averages and in reality they vary from 3-four years for a easy installation (for example replacing worn render with an insulated render system) up to 20 years for more in depth installations (such as an costly brick slip system to match masonry buildings).
The absolute costs and payback period are also misleading in that strong wall insulation often offers benefits besides thermal ones and these have a tendency not to be factored in. For instance, external wall insulation also weatherproofs the home, enhances sound proofing, offers air tightness, and revitalizes the appearance by covering worn render and masonry. A lot of individuals are also attracted by by no means once more having to paint their house.
