Featuring industry-leading systems suitable for solid wall and non-traditional properties, Permarock systems provide the ideal solution for reducing energy consumption in the UK's existing buildings and housing stock.

Retrofitting existing properties with external wall insulation (EWI) provides a strategic approach to enhancing energy performance, reducing heat loss, and extending the lifespan of the building fabric. External wall insulation systems offer a practical, cost-effective way to upgrade older buildings while minimising disruption to occupants and operations.

Aesthetically and technically, we apply the latest innovations in insulated render technology to enable buildings to be visually uplifted and to exhibit far greater thermal performance.

Our systems are suitable for all manner of retrofit projects: for high-rise and low-rise buildings, and for traditional and non-traditional forms of construction. Examples include solid wall or cavity wall, dense and no-fines concrete, brick, stone and metal, tile or timber clad structures.

UK Energy Efficiency Initiatives

As a trusted partner to architects, specifiers and housing providers, we have developed proven, thoroughly tested systems. They are are certificated through KIWA BDA Agréments® (BAW-24-331-S-A-UK, BAW-24-332-S-A-UK, BAW-24-333-S-A-UK, BAW-25-403-S-A-UK) to ensure full compliance with UK Building Regulations (including high rise buildings). They also meet the requirements of PAS 2030: 2023 / PAS 2035:2023 for use under the Government’s Energy Company Obligation (ECO) and other energy efficiency retrofit initiatives such as WH:SHF, WH:LG and more.

Our external wall insulation systems provide assured performance, safety and durability. Explore our retrofit pathways below:

High Rise Properties

One of the most important considerations for specifiers, when choosing materials for building façades, is the fire performance of the building envelope components. Particularly important is the performance on high-rise, multi-storey buildings. Permarock Mineral Fibre external wall insulation (EWI) systems are ideally suited for use on high-rise projects.

Social Housing

Social housing providers are one of our largest client groups. Accordingly, we have many years of experience of helping social landlords to plan and deliver large-scale decarbonisation schemes. In line with PAS standards and industry best practice, we help to design retrofit schemes that adopt a fabric-first approach.

‘Hard to Treat’ Properties

Permarock systems are designed to provide thermal and aesthetic improvements to all property archetypes but they are especially suited for use on ‘hard to treat’ properties, such as solid wall and non-traditional buildings, or where cavity wall insulation is not suitable.

Public & Community Buildings

Incorporating Permarock external wall insulation into a building envelope design can be a significant aid in achieving improved energy standards. Consequently, our external wall insulation systems are increasingly being used to improve the energy performance and aesthetics of public, commercial and community buildings.
