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.

How Our Insulation Solutions Stop Heat Loss

We offer two primary methods to combat heat loss: External Wall Insulation (EWI) and Internal Wall Insulation (IWI). EWI involves attaching a layer of thermal material to the outside of your property, which is then finished with a high-quality render. This method wraps your home in a protective thermal blanket, effectively solving issues with thermal bridging. If your home has historical features that must be preserved, or if you live in a property where external changes are restricted, our IWI systems provide a perfect alternative. By installing insulating boards internally, we improve thermal efficiency without altering the external aesthetic of your home.

Why Invest in Solid Wall Insulation Now

Investing in solid wall insulation is one of the most effective ways to improve your home energy efficiency and lower your monthly heating costs. Beyond the immediate financial benefits, our insulation services help prevent common issues such as condensation and black mould, which are prevalent in uninsulated solid-wall properties. For landlords and property owners in Rhondda Cynon Taf, improving your EPC rating is essential to meeting Minimum Energy Efficiency Standards (MEES). Our solutions ensure your property remains warm, dry, and fully compliant with current building regulations.

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.
