How do we protect your property while improving efficiency?

Our process begins with a detailed PAS 2035 compliant assessment to ensure any thermal intervention is appropriate for your specific building fabric. We prioritise breathable insulation materials that prevent moisture entrapment, a common issue in older properties with solid stone or brick walls. By choosing the right internal wall insulation or roof insulation solutions, we eliminate thermal bridging and cold spots that lead to damp and condensation. This measured approach ensures that your home remains healthy and continues to breathe as it was originally designed.

Navigating Planning and Cadw Requirements in Neath Port Talbot

One of the greatest concerns for owners of listed buildings is adhering to local authority and Cadw regulations. We handle the complexities of compliance effortlessly, ensuring that all proposed insulation works align with the necessary heritage requirements. Our PAS 2030 accredited team is well-versed in the specific building regulations for the South Wales area, meaning you do not have to worry about the finer details of planning permission or conservation area rules. We provide the technical expertise required to improve your home energy efficiency rating without compromising its aesthetic value.

The Benefits of Our Integrated Heritage Service

Beyond simple insulation, we offer a comprehensive end-to-end service by working in tandem with our sister company, Global Plastering. While we manage the complex retrofit and thermal upgrade, our colleagues specialise in traditional lime plastering and specialist finishes that are essential for historic building restoration. This partnership allows us to deliver a seamless finish that matches the original textures and styles of your property. Improving your EPC rating has never been more straightforward or aesthetically sympathetic.

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.
