How we approach sensitive insulation for period homes

Retrofitting a historic building requires a delicate balance between modern thermal performance and traditional material compatibility. Our PAS 2035 compliant approach ensures that every project begins with a thorough assessment of your building's unique characteristics. We avoid moisture-trapping materials that can damage older structures, instead opting for breathable insulation systems that allow your walls to breathe. Whether dealing with solid stone walls or complex timber frames, our methods prevent thermal bridging and condensation, effectively treating those persistent cold spots commonly found in Victorian and Edwardian properties.

Navigating Cadw compliance and local planning requirements

We recognise that working on a listed building or a property within a conservation area in Glyn-Nedd / Glyn-Neath requires adherence to strict guidelines. Our team is well-versed in navigating Cadw requirements and local planning regulations, ensuring that any thermal improvements are sympathetic to the historic appearance of your home. We manage the technical side of the retrofit process, providing you with the necessary expertise to satisfy planning authorities while meeting your goals for improved energy performance. Our focus is on achieving a warmer, more efficient home while strictly preserving the heritage features that make your property special.

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.
