Wall Insulation

There are 2 fundamental types of wall insulation, those being cavity wall insulation and solid wall insulation, both of which we will cover in this article.

Although insulating your walls is a positive measure to reduce your energy consumption and reduce carbon dioxide (CO2) one of the biggest causes of climate change, the first place to insulate would and should be your loft space, and subsequently depending on budget, your walls, solid or cavity.

Remember heat will always flow from a warmer area to a cold one. In winter, the colder it is outside, the faster heat from your home will escape into the surrounding air, escaping heat is your winter energy bills. The better insulated your home is, the more efficient your energy usage will be in saving you money.

There are grants available for both loft Insulation and wall Insulation.

Approximately one third of your heat loss in an un-insulated home, is lost through the walls, which is a fact, yet with wall insulation of a cavity wall, this can save you up to around £110 per year on your fuel energy bills.

Cavity Wall Insulation

If your home is post 1920 onwards the chances are, that it will have external walls made up of a cavity or small gap between the inside layer and the external brickwork layer. By filling the cavity wall space with a porous material this immobilises the air within the cavity (air is still the actual insulator) preventing convection and can substantially reduce you heat loss.

Cavity wall insulation is a very quick and effective method of insulating your home and saving you money. Filling cavity walls is a professional job requiring specialist equipment for the purpose of installation by registered installers such as the National Insulation Association (NIA).

Free Wall Insulation Grants

Wall insulation, cavity and loft grants are available to completely cover the cost of cavity wall insulation and loft insulation for your home dependent upon your entitlement, although if you are not entitled to one of the full insulation grants, you can still receive a grant for up to 70% of the cost. Grants are available to private households where anyone is aged 70 and above, or anyone in receipt of certain benefits, tax credits or allowances. All other home owners and private tenants will still qualify for a partial grant.

These grants will not last for ever, with the current scheme extended through till 2012. It is estimated these grants will cease completely by 2015. Grant funding can also stop and start particularly on free schemes, so applying for grants now would appear to be the best advice for all.

Around 45% of the heat lost in an un-insulated solid walled home is through the walls. Insulating your solid walls can save you around £375 a year on your energy bills.

Solid Wall Insulation

If your home was built prior to 1920, its external walls are likely to be solid rather than “cavity walls” and especially if you live in a rural community with stone walls, or a homebuilt in the Victorian era or earlier. In the UK 1 in 4 of our homes is of solid wall construction rather than cavity walls. Cavity walls are made of two layers, these being internal and external layers with a small gap or cavity between them. This cavity acts as a barrier to reduce heat flow through the solid wall.

Solid walls have no such gap incorporated when they are built and this allows more heat to pass through them, than through a cavity wall. Twice as much heat can be lost through an un-insulated solid wall as through an un-insulated cavity wall.

Any and all solid walls can be insulated from the inside or the outside.
Why Insulate you solid walls.

Solid wall insulation is an effective way to stop wasting energy and home, whilst at the same time reduce your impact on global warming. In winter a correctly insulated home keeps you warm and saves you money.

A solid wall, or walls can be insulated with internal insulation or external insulation . As with both options this can make your home warmer and more comfortable. By using wall insulation you could cut your heating costs by up to 40% simply by using less energy, although if you have draughty windows and doors this saving will not be achievable. Therefore you must look at your home as a complete entity when considering the types of insulation and where to start insulating your home.

Internal Solid Wall Insulation

The construction and installation of solid wall insulation usually takes the form of dry lining and or plastering. Other trades people may be required such as plumbers and electricians who will need to remove radiators and electrical sockets, therefore this is not usually to be attempted by the not so experienced DIY’er or handy man.

Remember any installation of dry lining within your home will reduce your room’s internal measurements on completion of the work. Any installers you approach to carry out work on your behalf ask them for;

1 Certificates of competence in their respective fields of expertise.
2 Examples of previous work.
3 What products does the installer recommend insulating your walls with to achieve a good energy efficiency saving (this should be a U value of around 0.35W/m2K).
4 What measures will be undertaken to prevent condensation forming on your wall structure once it is insulated.

Should you be thinking of external wall insulation this will most definitely require a qualified and competent specialist installer, who is trained and approved by the system designers and manufactures.
