How We Protect Historic Integrity During Thermal Retrofitting

Our approach to retrofitting listed buildings in Brynmawr is guided by the principles of PAS 2035. We recognise that these structures need to breathe to avoid damp and condensation issues. Instead of standard modern materials, we use breathable insulation systems that manage moisture effectively. Our team works meticulously to maintain your home's aesthetic appeal, ensuring that any internal wall insulation or loft upgrades remain sympathetic to the original architecture and comply with local conservation guidelines.

Meeting EPC Standards for Listed Property Landlords

For landlords in Brynmawr owning older, historic properties, keeping up with Minimum Energy Efficiency Standards (MEES) can be complex. We offer expert support in navigating the necessary consents, ensuring your property achieves a better EPC rating without compromising its listed status. By improving your thermal performance, we help you eliminate cold spots and reduce energy consumption, making your property more comfortable for tenants and more compliant with current UK regulations.

Heritage Property FAQs

Frequently Asked Questions

Answers to common questions about breathable historic building insulation, thermal bridging solutions, and PAS 2035 compliance across South Wales and South West England and South Wales.

Do I need planning permission to insulate my listed building in Ferndale?

+

Yes, in most cases, you will need Listed Building Consent for internal or external wall insulation. Because these works change the thickness of the walls or the materials used, local planning officers want to see that the heritage of the building is being protected. We can help provide the technical details needed for your application.

Why shouldn't I use cheap foam insulation on an old stone wall?

+

Old buildings were designed to be "breathable." Moisture travels through the stones and mortar and evaporates. If you put non-breathable foam against the wall, you trap that moisture. This leads to "interstitial condensation," which rots floor joists and causes damp patches. We use breathable wood fibre or mineral wool to keep your walls healthy.

Will I lose the original features like my coving or skirting boards?

+

We do everything we can to preserve the character of your home. Sometimes this involves carefully removing and reinstating skirting boards or using thinner, high-performance insulation in areas with intricate decorative features. Our partnership with Global Plastering allows us to replicate traditional finishes so your home looks exactly as it should—only warmer.

How long does it take to insulate a period property?

+

Every building is unique, but a typical internal wall insulation project for a terraced house usually takes between one and two weeks. This includes the preparation, the insulation fixings, and the specialist lime plastering finish.
