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.

Why choose between EWI and IWI for your Neath home

Every property requires a unique approach to thermal efficiency. Our team provides both External Wall Insulation (EWI) and Internal Wall Insulation (IWI), ensuring we find the right fit for your building type and budget. EWI involves adding an insulating layer to the outside of your property, which is often finished with a durable, weather-resistant silicone or K Rend finish that revitalises the look of your home. If you live in a conservation area or a listed building where changing the exterior is restricted, our IWI service offers a high-performance solution that adds thermal boarding to the interior walls, effectively eliminating thermal bridging without altering your home's character.

How we improve energy efficiency and EPC ratings

Improving your home's Energy Performance Certificate (EPC) rating is essential for modern comfort and long-term property value. Our retrofit projects are fully compliant with PAS 2035 standards, meaning every installation is backed by rigorous assessment and design processes. By significantly reducing heat loss through your walls, our insulation solutions make it easier for landlords to meet MEES regulations and for homeowners to enjoy a warmer, healthier living environment throughout the winter months. We take pride in helping our clients in Neath move toward a more sustainable and cost-effective future.

Professional installation and quality assurance

As a PAS 2030 accredited company, we uphold the highest standards of workmanship in every project we undertake. We understand the specific challenges posed by the South Wales climate, from high winds to driving rain, and we select materials that offer superior protection and longevity. Because we are registered with SWIGA, all our qualifying installations come with an insurance-backed guarantee, providing you with total peace of mind. Our team operates across a 35-mile radius of our base, bringing expert care to every detached house, apartment, or commercial office space we service.

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!"

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.
