Why Traditional Insulation Methods Fail Historic Homes

Historic buildings are typically constructed with solid walls that need to breathe to remain healthy and damp-free. Many modern, non-breathable materials can trap moisture inside the structure, leading to long-term issues like black mould and decaying timber. Our team uses advanced, breathable insulation solutions such as Spacetherm and specialised internal wall systems designed to reduce heat loss effectively. These materials allow your walls to function exactly as intended, ensuring that your home remains warm and dry throughout the year.

Our Expert Approach to PAS 2035 Retrofit Standards

Navigating energy upgrades in a listed building requires expert knowledge of Monmouthshire building regulations and conservation area rules. We handle the entire process, starting with a comprehensive PAS 2035 retrofit assessment to ensure your property is treated with the correct strategy. By working closely with our sister company, Global Plastering, we offer a seamless end-to-end service. We ensure that all insulation work is perfectly finished, maintaining the original aesthetics of your property while securing the modern thermal performance you require.

Achieving EPC Improvements for Listed Buildings

Whether you are a landlord aiming for MEES compliance or a homeowner looking to lower energy consumption, we make improving your EPC rating achievable. We focus on thermal bridging solutions and targeted insulation for solid walls, ensuring your investment makes a tangible difference to your comfort levels.

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.
