Why Standard Insulation Often Fails Heritage Homes

Historic buildings are designed to breathe. When modern, non-breathable materials are used on solid stone or brick walls, moisture becomes trapped, leading to damp, mould, and structural decay. Our approach focuses on thermal bridging solutions that do not compromise this breathability. By using advanced materials like wood fibre insulation and lime-based systems, we provide a robust barrier against heat loss that allows moisture to escape naturally. This is essential for protecting your property from the internal condensation that so often ruins older walls.

Our PAS 2035 Compliant Retrofit Process

Navigating the regulations for listed or conservation-protected buildings can be complex. As a PAS 2030 accredited contractor, we manage the entire process through a PAS 2035 compliant framework. We start with a thorough assessment to determine the specific thermal needs of your building. This ensures that every upgrade complies with building standards while being sympathetic to the heritage status of the property. You can rest easy knowing our work meets the strict requirements necessary for planning and conservation approvals.

Expert Finishes with Global Plastering

The beauty of a historic home often lies in its internal finishes. Because we operate alongside our sister company, Global Plastering, we offer a seamless end-to-end service. Once your breathable insulation is installed, our skilled plasterers apply traditional lime plastering techniques that match the original character of your property. This combined expertise means you do not need to coordinate multiple contractors; we handle the thermal performance and the final aesthetic finish under one roof.

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.
