How We Balance Heritage Preservation and Modern Performance

Retrofitting a historic property is not a one-size-fits-all process. We prioritise the use of breathable materials like wood fibre and aerogel to manage moisture effectively. This approach protects your solid wall structures from dampness and thermal bridging, which are common culprits behind cold homes and high energy bills. Our process begins with a professional assessment to ensure any insulation work respects the existing fabric of your building, keeping it dry and healthy for years to come.

Can You Improve EPC Ratings in a Conservation Area?

Many homeowners and landlords in Llanwrtyd Wells worry that their property type restricts energy improvements. Whether you are aiming to meet MEES standards for a rental property or simply want to reduce your monthly costs, we provide tailored solutions for Edwardian, Victorian, and listed builds. We navigate the complexities of local authority compliance and listed building consent on your behalf. Our team manages the entire process, ensuring that all upgrades meet current regulations without compromising the historical integrity of your 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.
