Loft-InsulationInsulating your loft is one of the most effective ways to save energy. You could save up to £145 a year on bills depending on your existing level of insulation and do your bit for the environment by saving around 1 tonne of CO2 per year*.

In many homes, even where insulation has been installed in the past, lofts are often damp, cold places, letting as much as 25% of your homes heat escape. Loft insulation is an effective way to save energy and money at home – a well insulated house keeps warmth exactly where you need it – indoors.

Loft insulation is effective for at least 40 years, and it will pay for itself over and over again in that time. The better insulated your home, the less energy you need to keep it warm – the more money you’ll save in the long run.

By saving energy, your household will produce less CO2. So, adding or topping up your loft insulation is a great way to do your bit – and reduce your impact on the environment. Below is a brief overview of the paybacks to be expected by simply increasing your loft insulation to the required amount.

Today, the recommended depth for loft insulation is 300mm, however the vast majority of houses do not meet this standard. Contact Bayview Contracts today and we will complete a free, no obligation survey on your home to check if your loft insulation meets the required standards.

Cavity Wall

Cavity Wall Insulation is one of the simplest ways to reduce your heating bills – by up to £110 per year*. According the Department of Environment as much as 35% of heat can be lost through your walls and by simply installing cavity wall insulation can lead to a reduction of 25% in your annual energy bills (even more in detached houses and bungalows).

The environmentally friendly Thermabead system is fully guaranteed and will not shrink, settle or crack. It will prevent damp, condensation, and mould for year after year. The system is extremely versatile and it can be used on a wide range of buildings, including apartments and commercial buildings.

Every domestic cavity wall installation completed by Bayview Contracts is guaranteed for 25 years by CIGA (Cavity Installation Guarantee Agency).

External Wall Insulation, before and after.

External Wall Insulation, before and after.

Internal and External

Solid walls loose even more heat than cavity walls; the only way to reduce this heat loss is to insulate them on either the inside or the outside.

Bayview Contracts continue to research the latest, most efficient and cost effective solutions to solid wall insulation (internal and external) to ensure that you the customer benefit from a tailored, bespoke solution that meets your specific needs.

How external wall insulation works
This involves adding a decorative weather-proof insulating treatment to the outside of your wall. The thickness of the insulation needs to be between 50 and 100mm and is usually installed where there are severe heating problems or the exterior of the building requires some form of other repair work providing the opportunity of adding insulation.

The savings
External wall insulation is more expensive than cavity wall insulation but it could save you around £385 a year on your energy bills and it could pay for itself in around 11 years.

A three bedroom semi-detached house could save around 1.9 tonnes of carbon dioxide (CO 2) a year.

The following table gives approximate costs, savings and paybacks for external solid wall insulation however the typical cost provided does not include any financial support or grants. Financial help may be available if you’re planning to make energy saving improvements to your home.

solid wall insulation Saving per year Total cost including installation CO2 saved per year
Internal Around £365 £5,000 – £8,500 1.8 tonnes
External Around £385 £10,500 – £14,500 1.9 tonnes

Internal-InsulationInternal wall insulation
Solid walls can also be insulated by applying internal wall insulation. Types include ready made insulation/plaster board laminates or wooden battens in-filled with insulation.

How internal wall insulation works
Insulation/plaster board laminates usually consist of plasterboard backed with insulating material typically to a total thickness of up to 90mm. The construction of the laminates reduces the amount of heat which would otherwise pass through into the wall and outside.

The savings
Internal wall insulation can be cheaper than external wall insulation and you could save around £365 a year on your energy bill.
A three bedroom semi-detached house could save around 1.8 tonnes of CO 2 a year.
