The cost of living crisis has heavily impacted the whole of the UK, whilst the record electricity and gas prices threaten to send more households into fuel poverty. The UK Government estimates that 13.2% of households suffered fuel poverty in 2020. This figure is only likely to rise along with the predicted price cap rises. Solutions for lowering your energy bills are extensive and varied. However, none provide the whole house impact of external wall insulation.
External Wall Insulation can halve your heating bill!
Applying just 90mm of EPS to an existing 1930 solid wall property should halve the heating element of your energy bill.
Ofgem forecasts the average annual energy bill for UK households to rise to an eye watering £3,582. An investment into external wall insulation is an investment with an eye on the immediate and long term future. Currently, British Gas places the average annual energy bill at £2,000, based on the average annual consumption of 12,000 kWh units of gas and 2,900 kWh units of electricity. Based on these figures, an external wall insulation on your property figures to save a household in excess of £500 per year.
A whole house solution
While loft insulation is always considered a must-do when it comes to improving the efficiency of your property - and while we absolutely agree with this, external wall insulation will actually have a bigger impact on your energy bills.
According to TheGreenAge, approximately 35% of the heat in your home escapes through the wall surface. Adding a layer of EWI can dramatically reduce the rate of heat loss from your house to the external environment. Furthermore, improved insulation and heat retention ensures that the heating system within your home does not need to fire up as frequently, or stay on for prolonged periods to offset the loss of heat. There has never been a better time to limit your households' exposure to energy price rises by reducing your demand. Lower your energy bill prices with the below EWI.
EWI Store offers 3 primary insulation solutions for external wall insulation: Rockwool, K5, EPS.
- Rockwool offers a premium solution with complete anti-combustibility and acoustic insulation, with dual density composition
- Kingspan Kooltherm K5 is a premium space-saving solution, designed with phenolic composition
- EPS, or Expanded Polystyrene insulation, is the most popular wall insulation solution due to its fantastic performance relative to cost
We also offer XPS insulation, which is typically used when insulating beneath the DPC down to floor level.
Solid wall properties are particularly vulnerable to allowing colder temperatures to transfer from outside the property to the inside. Cavity wall properties can also benefit from external wall insulation, as well as improving the visual appearance of your property.
EWI in practice
The premier example of external insulation in action is the Wilmcote House renovation project. The project was carried out by Rockwool in partnership with the Portsmouth City Council. The project targeted a reduction in dwelling heating demand by 90% and a minimum 30-year extension to the lifetime of the estate.
