EXTERNAL WALL INSULATION /
PRIVATE HOMEOWNERS /
PermaRock Products Ltd, is one of the leading designers, manufacturers and suppliers of external wall insulation systems with over 30 years experience in supplying external wall insulation in the UK.
What is PermaRock External Wall Insulation?
PermaRock external wall insulation has been developed to improve the energy efficiency of existing buildings, particularly solid wall or “Hard To Treat” homes that are not able to benefit from Cavity Wall Insulation, by the application of rigid insulation to the external wall surfaces. The insulation is reinforced and finished with a weatherproof render.
Acting as a ‘thermal jacket’ around a property, PermaRock systems are Energy Savings Trust (EST) approved and are installed by specialist installers throughout the UK.
Why PermaRock External Wall Insulation?
With 45% of heat lost through the walls on Hard to Treat and Solid Wall Homes, the application of an external wall insulation system will provide a number of positive benefits to the homeowner:-
- Lower fuel bills: High levels of energy efficiency can be achieved over other forms of insulation resulting in savings on energy bills, especially where other measures are not suitable (non-cavity/solid wall properties). An average semi-detached home could typically save £400 - £500 per year on fuel costs (Source: EST).
- Interstitial or internal condensation on walls can be eliminated, and the attendant problems of damp internal surfaces and mould growth can be overcome.
- Prolonged building life: the building fabric is protected against the effects of the weather (systems have an assessed minimum lifetime of 30 years).
- Improve the buildings appearance: A range of decorative renders and effects are available to improve or replicate the appearance of an existing dwelling.
- Installation is undertaken whilst you remain in your property and normally takes approximately 2-3 weeks to complete.
- 10 year material guarantee supplied.
- Some partial funding may be available.
What will it cost?
This is dependant on a number of factors but typical for a semi-detached home the cost of supply and installation of a system would be between £6000 - £7500. Please note costs can vary considerably depending upon the wall configuration of your home.
