How We Preserve Your Property While Improving Energy Efficiency

We follow a strictly controlled process to ensure your property remains compliant with Cadw requirements and local planning authorities. Our approach begins with a thorough assessment to identify where thermal bridging and heat loss occur most frequently in your building. Because period properties, such as those found in Neath Port Talbot, were built to breathe, we utilise specialist breathable insulation systems that prevent moisture build-up and damp issues. By choosing our PAS 2035 compliant services, you receive a holistic plan that considers the entire house as a single system, ensuring long-term performance and material compatibility.

Can You Insulate a Solid Wall Property Without Losing Its Character?

Many homeowners in Pontardawe worry that adding insulation will hide period features or alter the look of their home. Our expertise in Internal Wall Insulation allows us to boost thermal efficiency significantly without changing your property exterior. Working closely with our sister company, Global Plastering, we offer a seamless finish using traditional materials like lime plaster. This ensures your internal walls remain healthy and aesthetically consistent with the age of the building, providing a complete end-to-end service from the initial retrofit design to the final decorative finish.

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.
