Retro-fitting your home with external solid wall insulation will save you thousands of pounds in heating bills. Typical savings gained amount to 35% of your annual heating bill
It will also increase the value of your home and help the environment by cutting carbon emissions.
In fact the government consider solid wall insulation to be so important they have now introduced a financial incentive scheme called the Green Deal Cash back Scheme to help pay for your home to be warm and dry with lower fuel costs!
How Effective is S.W.I ?
External Solid Wall Insulation ( S.W.I) involves fixing a layer of thermal cladding to the outside walls and then protecting it from the weather using pre-coloured renders. It can be fitted to virtually any type of house construction. Benefits include:
* 85% Reduction in Heat Loss
* £450+ p.a Energy Bill Savings
* Condensation Damp Eliminated
* Free Grants & Subsidies for All
* Increased Property Value
* Healthier Living Environment
Take a look at the infrared image of the building above and compare it to that of the house below which has not been thermally upgraded with solid wall insulation.
The blue sections are cold so no heat is escaping through the insulated exterior solid walls . However, as the red colour shows, the house with no insulation is simply leaking heat at an alarming rate.
Thinking of our wallets and our health I think we would all prefer to live in the warm and dry home in the first photo.
Standard Brick Solid Wall Homes
Over 5 million UK homes built before 1920 were constructed with walls of solid 9 inch brick and no insulation. With no cavity to insulate, they are poor at retaining heat in the home and are increasingly expensive to keep warm and dry during winter.
Wrongly called “single skin” walls,these are in fact sturdily built using double rows of bricks laid lengthways called “stretchers” .These are knitted together at various intervals by single bricks laid end-ways on, called “headers”.
Traditionally, the only solid wall insulation technique was internal dry-lining. This has now changed,and thanks to Government subsidies and Grants,exterior solid wall insulation is now recognised as being the most effective thermal improvement for solid wall homes.
Non-Traditional Solid Wall Houses
Following World War 2 and the subsequent baby boom Councils were faced with an unprecedented and urgent demand for housing. Solid brick built homes were expensive and time-consuming to build. So new methods of more affordable house construction were introduced to meet this surge in demand but solid wall insulation was not considered at all in the design due to low heating costs.
Designs based around using concrete and a steel frame became common place. Such homes included Airey, Woolaway, No Fines and BISF and they were very popular and quickly snapped up with no concerns about a lack of any solid wall insulation
Thermal efficiency and CO2 reduction were not considerations in those days but the good news is that there is now a range of solid wall insulation systems suited to all of these non-traditional builds. There is no longer any reason why a Woolaway or BISF home should not have as good a degree of insulation as a new house being built today.
