Professional solid wall insulation services in Tredegar

If you live in a traditional solid wall property in Tredegar, you likely understand the struggle of keeping your home warm during the colder months. Many older homes in Blaenau Gwent were built without cavity walls, meaning heat escapes rapidly through the brickwork, leading to high energy bills and persistent condensation issues. At Global Energy Insulation, we provide expert thermal solutions that transform these cold, damp spaces into comfortable, energy-efficient homes. As your local PAS 2035 retrofit specialists, we are committed to helping you improve your property performance while adhering to strict UK building regulations.

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.

Should you choose external or internal wall insulation

Choosing the right method for your property depends on its structure, layout, and your personal requirements. External Wall Insulation (EWI) involves fixing insulating material to the outside of your home, finished with a high-quality weather-resistant render. This is excellent for protecting the structure and significantly reducing heat loss without losing internal space. Alternatively, Internal Wall Insulation (IWI) is applied to the inside of your external walls, making it the preferred choice for properties where the external character must be preserved, such as certain listed buildings or those in conservation areas. Our team will assess your home to determine which approach offers the best thermal bridging solutions for your specific building type.

Why landlords and homeowners trust our PAS 2035 standards

With MEES compliance becoming a priority for landlords across South Wales, improving your EPC rating is no longer optional. Our team is fully PAS 2030 compliant and provides comprehensive PAS 2035 retrofit coordination to ensure every project meets national efficiency standards. By partnering with us, you gain the peace of mind that comes with SWIGA-backed insurance and the expertise of a CHAS-accredited company.

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.
