Professional Solid Wall Insulation in Crickhowell

Many older properties throughout Crickhowell and the wider Powys area share a common challenge: solid wall construction that allows heat to escape rapidly. Because these homes lack a cavity, they often suffer from cold walls, persistent dampness, and high energy bills. Global Energy Insulation provides expert solid wall insulation solutions designed to transform these characterful buildings into warm, energy-efficient homes. Whether you live in a traditional stone cottage or a Victorian terrace, our team is here to help you improve your home energy efficiency and lower your monthly heating costs.

Why Choose Our Solid Wall Insulation Services in Ferndale?

Whether you require External Wall Insulation (EWI) or Internal Wall Insulation (IWI), Global Energy Insulation delivers SWIGA-backed heat loss solutions to lower your high energy bills and improve your property's EPC rating across South Wales and the South West. Working seamlessly alongside our sister company, Global Plastering, we guarantee a flawless, fully compliant, end-to-end retrofit finish.

Understanding External and Internal Wall Insulation Options

We specialise in two primary methods for treating solid walls: External Wall Insulation (EWI) and Internal Wall Insulation (IWI). EWI involves fixing an insulating layer to the outside of your property, which is then finished with high-quality weather-resistant rendering. This is excellent for heat loss reduction and protecting the exterior fabric of your home. If you prefer to keep the exterior appearance of your property unchanged, our IWI solutions are applied to the inside surfaces. Our PAS 2030 accredited team will assess your property to determine the most effective strategy to stop thermal bridging and create a consistent, comfortable indoor environment.

Improving EPC Ratings and MEES Compliance for Landlords

For landlords in Crickhowell, reaching the required EPC rating is essential for legal compliance and property value. Our retrofit services are designed to help you meet Minimum Energy Efficiency Standards (MEES) effortlessly. By upgrading your insulation, you not only avoid the pitfalls of fuel poverty for your tenants but also significantly reduce the risk of structural issues such as black mould and condensation. We provide full PAS 2035 support, ensuring that all works are documented, compliant, and tailored to the specific needs of your rental portfolio.

Solid Wall Insulation FAQs

Frequently Asked Questions

Have questions about stopping heat loss, improving your EPC rating, or choosing between EWI and IWI? Find answers about our PAS 2035 accredited solid wall insulation services across South Wales and South West England, South Wales, and the South West.

How long does it take to install external wall insulation?

+

For a standard semi-detached house in Ferndale, the process usually takes between two to three weeks, depending on the weather. This includes the preparation, fixing the insulation boards, and applying the final render finish.

Will I lose much space with internal wall insulation?

+

We use high-performance materials that provide maximum warmth with minimum thickness. While you will lose a few centimetres of room width, the trade-off is a significantly warmer, more comfortable living space that is much cheaper to heat.

Do I need planning permission for EWI?

+

In many cases, EWI falls under "permitted development." However, if you live in a conservation area or a listed building, or if the insulation significantly changes the look of the street, permission may be required. We can help you understand the requirements for your specific location in Rhondda Cynon Taf or beyond.

Can solid wall insulation stop damp?

+

Yes, it is highly effective at stopping penetrating damp and condensation. By keeping the walls warm, moisture in the air no longer settles on them as water droplets, which prevents the growth of black mould.
