Design, Technical & On-Site Support

One of the most valuable benefits to specifying a PermaRock system is the knowledge that there is an extensive level of support provided alongside our products.

With over 30 years’ experience in the construction industry, PermaRock will pro-actively engage in discussions on the development of façades with the project design and construction teams and is able to offer significant technical support and advice on design, thermal, fire and aesthetic qualities to help ensure the finish and performance achieved by the specified system are of the highest standard.

Registered Installers & On-Site Technical Support

Installation of PermaRock systems is undertaken by our nationwide network of trained and registered installation contractors.

Installers receive regular training updates and are kept abreast of the latest innovations and product developments via PermaRock technical bulletins and their performance is monitored to ensure continuing high levels of quality and performance.

PermaRock installation contractors operate in all areas of the UK and we can provide details, on a project-by-project basis, of approved installers capable of carrying out the installation of any PermaRock system based on project size, location and programme requirements.

Many of our registered installers hold third-party accreditation through the BBA, and other accreditation bodies, to PAS 2030 / 2035 to work under Government energy efficiency initiatives. 


Our track record is second to none, with our external wall insulation and render systems installed in some of the most exposed locations in the UK. However, for added peace of mind, PermaRock can provide a 10 year materials guarantee on every project. 

We can also offer an added level of assurance to our clients through the PermaGuard® Insurance-Backed Guarantee for a small one-off premium.

The PermaGuard® Guarantee is available for terms up to 10 years. In the unlikely event of any issue arising, it covers defects which may result from the design, materials or installation of the external wall insulation or render system.

After Sales Service & Maintenance

The successful installation of a PermaRock system is not the end to PermaRock’s involvement with a project.

PermaRock provides aftercare manuals for its systems, detailing how maintenance can be carried out for routine tasks such as cleaning, minor repairs, modifying or adding new fixtures and fittings.

PermaRock Technical and Sales representatives are always available to discuss any aspect of a scheme, providing you with the necessary support on existing projects or for when you wish to move on to your next PermaRock scheme - for support please call 01509 262924 or email [email protected].
