EXTERNAL WALL INSULATION / REFURBISHMENT /
SOLID WALL & NON-TRADITIONAL HOUSING /
PermaRock systems have been used extensively across the UK, from the Shetland Islands and Western Isles in the North, to the extremities of Cornwall in the far South West, in urban and rural environments and in exposed and sheltered locations.
PermaRock systems are designed to provide thermal and aesthetic improvements to all forms of housing but are especially suited for application onto ‘Hard To Treat’ homes, such as solid wall and non-traditional housing or where cavity wall insulation is not suitable or possible.
PermaRock external wall insulation (EWI) systems provide a thermal jacketing effect that stabilises the structure by reducing thermal movements whilst protecting the building fabric from water and weathering, extending the buildings useful life by a minimum of 30 years whilst enhancing comfort levels by eliminating cold bridging, dampness and condensation.
The application of a PermaRock EWI system will raise the temperature of the building fabric, reducing interstitial condensation and dampness, allowing drying out to occur. Reduction in the moisture content of concrete reduces reinforcement corrosion and can therefore prolong the life of the structure - a particularly important effect with PRC (prefabricated reinforced concrete) buildings.
Non-Traditional Housing
PermaRock is able to offer solutions for many PRC house types, as well as for other non-traditional or system built types, including the following:
Airey, BISF, Bison, Cornish, Dorran, Easiform, Hawthorne-Leslie, Hawksley BL8, Orlit, Reema, Spooner, Swedish Timber Frame, Tarran, Trusteel, Unity, Vic Hallam (various), Wates, Wimpey No-Fines, Woolaway
Please note that a structural survey may be required as properties should be structurally sound to accept the EWI system load.
