Professional Solid Wall Insulation in Nailsea

If you live in a period home or a property built before the 1930s in Nailsea, you likely have solid walls rather than cavity walls. Without proper thermal protection, these walls act like a giant heat sink, drawing warmth out of your living space and pushing your energy bills up. Global Energy Insulation provides expert solid wall insulation solutions across North Somerset, helping homeowners and landlords tackle cold rooms and damp issues at the source. Whether your property is a classic Victorian terrace or a modernised non-traditional build, our team is here to restore your comfort.

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 to fix thermal bridging. External Wall Insulation, or EWI, involves applying high-performance insulation boards to the outside of your property, which are then finished with a weather-resistant render. This is an ideal solution for upgrading the thermal performance of a home without reducing the internal floor space. If your home has strict planning constraints or unique architectural features that must be preserved, we also offer Internal Wall Insulation, known as IWI. This process involves installing insulation to the inner surfaces of your external walls. By partnering with our sister company, Global Plastering, we provide a complete service that includes the necessary plastering and finishing to ensure your home looks perfect inside and out once the work is complete.

Why choose our PAS 2030 accredited team?

Energy efficiency is a complex field, and getting it right requires expertise that goes beyond basic construction. As a fully PAS 2030 accredited company, we operate under the strict PAS 2035 retrofit standards to ensure every project is handled with precision. From conducting thorough thermal assessments to managing the installation, our team prioritises safety and quality. We hold all necessary insurance, including public liability, and offer SWIGA-backed guarantees for solid wall installations, providing you with total peace of mind for years to come.

Improving your EPC rating and MEES compliance

For landlords in Nailsea and throughout North Somerset, hitting the right energy efficiency targets is no longer optional. With Minimum Energy Efficiency Standards, or MEES, requiring properties to meet specific EPC ratings, solid wall insulation is often the most effective way to protect your investment. By reducing heat loss through your walls, you not only make your property more attractive to tenants who want lower utility bills but also ensure you stay compliant with the latest UK building regulations. We help you navigate these requirements, providing the documentation and technical standards needed to boost your property's performance.

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.
