External Wall Insulation is a form of insulation fixed to the exterior of an existing or new dwelling. This is then rendered to give a protective and decorative coating to the existing façade.
Did you know that around 45% of the heat lost in an un-insulated solid walled home is through the walls. Insulating your solid walls can reduce heat loss and can save you around £400 - £500 a year on your fuel bills.
If your home was built before or around 1920, its external walls are likely to be solid rather than Cavity walls. Cavity walls are made of two layers with a small gap or cavity between them.
This cavity acts as a barrier to reduce heat flow through the wall. Solid walls have no such gap and this allows more heat to pass through them than through cavity walls. In fact, twice as much heat can be lost through an un-insulated solid wall as through an un-insulated cavity wall.
The good news is that, like cavity walls, solid walls can be insulated – from the inside or the outside.
External wall insulation is an effective way to stop wasting energy and money at home. In winter, a well insulated house keeps warmth exactly where you need it – indoors.
Castle Point Insulation are currently involved in many External Wall Projects, Insulating & Rendering: Private Houses, Social Housing Stock, Schools, Park Homes and Commercial Properties.
All our External Wall Insulation installations are covered by an independent guarantee.
External Wall Insulation reduces your Heat consumption plus:
- Provides greater warmth and comfort
- Significantly lowers energy bills
- Reduces external property maintenance
- Increases value of property
- Minimises damage to the environment
- Extends the lifespan of buildings
- Improves the appearance of buildings
Benefits for the Property Owner:
- Building life is extended through the weatherproofing and thermal upgrade of the property
- Some normal maintenance expenditure can be avoided. Worn render can be covered, without chipping off the old; and extensive re-pointing is no longer required
- The building's thermal capacity is increased, returning heat to the interior and reducing heat loss or heat gain - resulting in typical savings of 25% against the annual fuel bill
- The façade can be remodelled and rejuvenated for new uses
- Value is added to the property
Technical Benefits:
- Insulates external walls to produce the desired U-value without condensation risk
- Allows the fabric of the building to act as a heat store, increasing thermal efficiency, preventing cold bridging, condensation and mould growth
- Stabilises the structural fabric preventing movement due to thermal shock
- Contributes to sound reduction
Benefits for the Environment & Social Welfare:
- The Government has set out clearly defined targets for CO2 reduction. Each m2 of 50mm insulation could save one tonne of carbon dioxide emission over the life of a building.
- Reduces pollution and improves environment locally, as well as globally
- Upgrades run down housing stock
