Mineral Fibre External Wall Insulation Systems

PermaRock Mineral Fibre external wall insulation systems are a non-combustible, vapour permeable energy efficiency measure that allows homeowners and landlords to improve the energy performance and visual appearance of their property.

With up to 35% of heat lost through the walls on uninsulated homes, the application of external wall insulation will provide a number of positive benefits to your home, over other energy efficiency measures.

Key Benefits - External Wall Insulation

Lightweight, cost effective insulation
Save up to £425* per year on your fuel bill
Save around 1.8 Tonnes* of carbon dioxide per year
Improve the appearance of your home – potentially increasing the property’s value by up to 14% (Department of Energy and Climate Change Report)
Is applied with minimal disruption
Will not reduce the floor area (living space) of your property
Reduces condensation on internal walls and can help prevent damp (but will not solve rising or penetration damp)
Improves weatherproofing and can increases the life of the existing property by protecting the existing substrate from the weather

Approvals	BRE Global Certification: BRE Certificate No. 158/12
Thermal Performance	Systems can be designed to achieve U-values which satisfy or exceed current UK Building Regulation requirements.
Weather Resistance	Provides a weather resistant cladding to new and existing backing walls of brick and block masonry, dense and no-fines concrete and sheathed light gauge steel frame and timber frame constructions. Can be designed buildings in locations where the wind driven rain exposure classification is very severe.
Wind Loads	Using a combination of adhesive bonding and mechanical fixing, these systems can be designed to withstand all anticipated wind load (suction) scenarios in the UK.
Impact Resistance	Systems can achieve levels of hard body impact resistance in excess of 40J and can be designed for the zones associated with Categories I, II and III as defined in ETAG004
Fire Performance	Class A1 insulation (BS EN 13501-1:2007 + A1:2009). Class O surfaces as defined in the Building Regulations when tested to BS 476 parts 6 and 7 can be achieved. Fire tested in accordance with BS 8414-1: 2002 - compliant with BR 135 Annex A; 2003 (Acrylic Finish).
Water Vapour Permeability	The systems are water vapour permeable. The rate of permeability depends on the system (thickness and decorative finish type) selected
Design Life	Systems can be considered to have a design working like of at least 30 years. Lifetimes significantly in excess of 30 years can be achieved with proper maintenance and repair if damaged
