External wall insulation is a cladding system, which wraps the entire house in suitable insulation and covers it with a water proof coating. Here shows a house being wrapped in expanded polystyrene.
This is not only the most efficient way to insulate a building but, also gives a crisp, smart and completely maintenance free finish to your home.
External wall insulation uses the fabric of the building like a storage radiator. Heat can no longer escape through the outer layer of insulation and is reflected back into the living areas, creating a constant warm home.
The main benefits of external insulation are:
* Reduced heating bills
* Internal living space unaffected.
* Reduces cold bridging
* Improves the airtightness of a property
* Eliminates cold and damp from poorly insulated walls.
* Improves a property’s BER rating.
* Improves structural stability through protection.
* 800 colours and brick finishes available.
How is External Wall Insulation applied ?
The required type and size of insulation is calculated. The window sills and reveals are removed to eliminate cold bridging. The insulation panels are then adhesively fixed to the walls. The boards we use are tongued and grooved to help keep them straight and plumb.
The boards are then mechanically fixed to ensure stability. We use not only thermo dowells to fix the boards but also use a dowell cap for greater thermal bridging. A mesh and plaster base coat is then applied to the boards.
An aluminium sill or a Deco Plan board is used to replicate concrete sills. The finished render system, which has 800 possible colours is then applied.
