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 versus Internal Wall Insulation

Choosing the right method for your property depends on your specific needs and the construction type of your home. External Wall Insulation (EWI) involves fixing a thermal layer to the outside of your property, which is then finished with a high-quality, weather-resistant render. This is ideal for those looking to improve the aesthetics of their home while completely sealing the building envelope against thermal bridging.

Alternatively, Internal Wall Insulation (IWI) is the preferred choice for properties where the external character must be preserved, such as period homes or listed buildings in conservation areas. By adding insulation to the interior surfaces, we can drastically reduce heat loss without altering the external facade. Our team carefully assesses your property to recommend the most effective approach for your specific wall type, be it solid brick, stone, or non-traditional construction.

Why is Professional Retrofit Compliance Essential?

Working with an unaccredited installer can lead to poor performance, moisture trapping, and failure to meet building regulations. Our projects are delivered in strict accordance with PAS 2035 whole-house retrofit standards, ensuring that every detail is considered, from ventilation to thermal efficiency. We manage the process from start to finish, including the involvement of a qualified retrofit assessor and coordinator. Whether you are an HMO landlord struggling with MEES compliance or a homeowner wanting to reduce your carbon footprint, our expertise ensures that your property upgrade is fully compliant, safe, and built to last.

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.
