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 Solid Wall Properties Require Expert Insulation

Unlike modern builds with cavity walls, solid wall properties lack the built-in gap that acts as an insulating barrier. This often leads to cold walls, persistent draughts, and the development of damp and mould. Our insulation systems are designed to bridge this gap, significantly improving your EPC rating and tackling thermal bridging at the source. Whether you own a traditional stone terrace or a non-traditional build like an Airey or Cornish unit, we have the technical expertise to deliver high-quality, long-lasting results.

The Benefits of Our Retrofit and Insulation Approach

Our insulation projects go beyond simply adding layers to your walls. By choosing our professional services, you are investing in a comprehensive retrofit process that complies with the latest PAS 2035 standards. This approach ensures your property stays warmer for longer, effectively reducing your fuel consumption and helping to alleviate fuel poverty. Additionally, our external and internal wall insulation techniques offer the chance to refresh your property exterior with a modern, high-quality render finish, simultaneously increasing your home's market value.

How We Ensure Quality and Peace of Mind

Quality assurance is at the heart of everything we do at Global Plastering. We are proud to be a SWIGA-accredited installer, which means we can provide insurance-backed guarantees on every solid wall insulation project we undertake. As a fully insured company with registered waste carrier status, we handle every aspect of your installation with total professionalism. We work closely with homeowners and landlords across South Wales to ensure all energy efficiency improvements meet the necessary legal standards for compliance.

Frequently Asked Questions About Solid Wall Insulation

Can this help with my EPC rating?

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.
