Expert Solid Wall Insulation for Homes in Aberhonddu and Brecon

If you live in a period property or a solid wall home in Aberhonddu and Brecon, you may be familiar with the struggle of rising energy bills and draughty, cold rooms. Many homes across Powys were built with solid walls that lack cavity space, meaning they lose heat rapidly through the masonry. Global Energy Insulation provides professional solid wall insulation solutions tailored specifically to the unique architecture found throughout the Brecon area. We help homeowners and landlords reduce heat loss and create a more comfortable living environment while addressing the specific challenges of local property types.

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.

Why Your Property Needs Thermal Upgrades

Older properties in Powys often suffer from thermal bridging, where heat escapes through cold walls, floors, and junctions. This not only forces your heating system to work harder but can also create the perfect conditions for condensation and black mould. By choosing our EWI or IWI services, you are taking a proactive step to improve your home energy efficiency and significantly boost your EPC rating. Whether you need to meet MEES compliance for a rental property or simply want to cut your monthly heating costs, our PAS 2030 accredited team offers the expert guidance needed to transform your home.

Comparing External and Internal Wall Insulation

For external wall insulation, we apply a high-performance thermal layer to the outside of your property, which is then finished with a durable, weather-resistant render. This process protects the building fabric while providing a fresh, aesthetic update to your home. If you live in a listed building or a property where the exterior character must be preserved, internal wall insulation is an excellent alternative. We install specialist thermal boards on the inside walls, effectively trapping heat and preventing the chill from seeping through your masonry. Our team can advise on the best approach for your specific property type.

Seamless Service with Our Expert Partners

What truly sets us apart is our end-to-end approach to home improvement. While Global Energy Insulation focuses on the technical thermal requirements and PAS 2035 retrofit standards, we work in perfect harmony with our sister company, Global Plastering. This partnership ensures that any internal insulation work is finished with high-quality plastering and professional finishes, leaving your home looking pristine. You do not need to juggle multiple contractors; we manage the entire project from initial assessment to the final quality check, all backed by SWIGA-approved insurance guarantees.

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.
