Preserving Heritage Through Breathable Insulation

When dealing with solid wall properties or historic builds, breathability is paramount. We focus on non-invasive, vapour-permeable systems that allow your walls to breathe naturally, preventing condensation and black mould issues that often plague improperly insulated period homes. For your internal walls, we utilise natural materials such as wood fibre or cork boards, which provide excellent thermal bridging solutions without changing the external appearance of the building. By selecting the right materials for the age and condition of your property, we ensure that your insulation installation enhances comfort while maintaining the building's essential breathability.

Navigating Conservation and Planning Requirements

We recognise that making energy efficiency improvements to listed buildings in Abercarn requires careful coordination with local planning departments. Our team is well-versed in the complexities of UK building regulations and the specific constraints of conservation areas in the Caerphilly region. We handle the technical side of your project with precision, ensuring that all proposed insulation works are sympathetic to your home's historic value. By aligning our approach with PAS 2035 whole-house retrofit standards, we provide you with a compliant, safe, and effective path to a warmer, more energy-efficient home.

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.
