Why Choose Us for Solid Wall Insulation?

Based in Ferndale and covering South Wales and South West England, Global Plastering is your trusted local partner for tackling cold, hard-to-heat homes. Whether you need External Wall Insulation (EWI) to transform a solid brick property or Internal Wall Insulation (IWI) to preserve a historic Victorian façade, our fully guaranteed retrofit services eliminate thermal bridging, lock in heat, and dramatically improve your EPC rating.

Reducing Heat Loss in South Wales Homes

Many older properties in South Wales lack effective wall insulation, leading to significant heat loss and persistent cold spots. By installing high-performance External Wall Insulation (EWI) or Internal Wall Insulation (IWI), we create a thermal barrier that keeps warmth inside during the winter and prevents overheating in the summer. Our solutions are designed to target the root cause of high energy bills, helping you improve your home's EPC rating and contribute to regional decarbonisation goals.

Why choose between external and internal insulation?

Choosing the right method depends on your property type and individual circumstances. External Wall Insulation involves fixing insulating boards to the outside of your home, finished with high-quality silicone render or K Rend, which not only improves thermal performance but also gives your property a fresh, aesthetic facelift. For properties where changing the external appearance is restricted, such as in certain conservation areas, our Internal Wall Insulation service offers a precise alternative. We use advanced dry-lining and skimming techniques to ensure your interior remains warm, dry, and professional in finish.

Reliable Retrofit Compliance and Quality Standards

Quality and safety are at the core of everything we do. Our team operates as a PAS 2030 accredited installer, ensuring that all work meets the rigorous PAS 2035 retrofit standards. For landlords and commercial clients, our services are vital for meeting modern MEES energy efficiency regulations.

What Our Clients Say About Global Plastering

"Excellent work the team removing our old 1970's cladding and replacing it with insulation and a rendered finish. The job went smooth from start to finish with all old materials removed from site. We are very pleased with the end result and would thoroughly recommend Global Plastering."

A. Jenkins (Ferndale)

"Dilwyn and his team were brilliant and made a lovely job of our EWI. They were very friendly, hard-working, and left no mess at the end of each day. Our house looks great and we can definitely feel the benefits of the insulation already. I'm very glad we chose EWI especially with energy costs as they are now."

G. Toogood (Bristol)

"Charlotte and the team were professional, reliable, and excellent at communicating throughout. They did a fantastic job of skimming and rendering the back of our house during our renovation. Superb quality of work and highly recommended!"

M. Lewis (Cardiff)

FAQ

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited solid wall insulation, EWI solutions, and retrofit services in South Wales and South West England and across South Wales.

Does solid wall insulation cause damp?

+

When installed correctly by professionals like us, it actually helps prevent damp. By keeping the internal surface of the wall warmer, it stops water vapour in the air from condensing on the wall. We always make sure there is adequate ventilation as part of our PAS 2035 assessment to keep the air fresh and the walls dry.

Do I need planning permission for External Wall Insulation?

+

In many cases, EWI falls under "permitted development." However, if you live in a conservation area, a listed building, or if the insulation significantly changes the look of the front of your house, you might need permission. We can help advise you on the local rules in Rhondda Cynon Taf and beyond.

How long does the installation take?

+

For a standard semi-detached or terraced home, External Wall Insulation usually takes between 2 to 3 weeks, depending on the weather. Internal insulation can be faster but depends on how many rooms you are doing at once. We always aim to keep the workspace tidy and the disruption to a minimum.

Is it worth the investment?

+

Solid wall houses lose about twice as much heat as those with cavity walls. By insulating, you are making a long-term investment that protects the fabric of your building, slashes your carbon footprint, and saves you money every single month on your gas or electric bills.
