How We Protect Your Property Fabric

Insulating a listed building requires a deep understanding of how traditional structures breathe. We avoid standard modern materials that can trap moisture and cause long-term damage. Instead, our PAS 2030 accredited team focuses on breathable Internal Wall Insulation and targeted roof solutions designed specifically for solid wall properties. We ensure that our methods prevent damp and condensation, which are common issues in uninsulated period homes. By managing thermal bridging effectively, we eliminate the cold spots that often plague Victorian and Edwardian homes in the Neath Port Talbot area.

Meeting Planning and Cadw Compliance

We navigate the complex world of heritage property regulations so you do not have to. Our team works closely with local planning departments and ensures all work complies with Cadw requirements. Whether you are aiming to improve your EPC rating to meet MEES standards for a rental property or simply want to lower your heating costs, we follow rigorous PAS 2035 standards. This methodical, whole-house approach guarantees that every modification is justified, safe, and sympathetic to the original design of your building.

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.
