Specialist Solid Wall Insulation in Treorci and Treorchy

If you own a solid wall property in Treorci or Treorchy, you are likely all too familiar with the challenge of keeping your home warm. Many traditional homes, particularly Victorian and Edwardian terraces across the Rhondda Cynon Taf region, were built without the cavity walls found in modern construction. This often leads to significant heat loss, cold walls, and rising energy bills. At Global Plastering, we are the local specialists dedicated to transforming the thermal performance of your home through expert internal and external wall insulation solutions.

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.

How Our Insulation Solutions Solve Heat Loss

Our approach focuses on stopping heat from escaping through your walls, which is the primary cause of thermal bridging in older buildings. We provide two main paths for improvement: external wall insulation, which involves applying a protective, insulating layer to the outside of your property, and internal wall insulation, which is ideal if you want to preserve the exterior character of your home. Both methods effectively create a thermal barrier that keeps warmth inside during the winter and helps maintain a comfortable temperature throughout the year.

Why Choose Our PAS Accredited Retrofit Services

Quality and safety are at the core of everything we do. As a PAS 2030 accredited installer, we adhere to the highest standards of energy efficiency and building safety. Our team is fully trained to manage complex retrofitting projects, ensuring that every installation complies with PAS 2035 standards. We are also SWIGA-accredited, meaning you benefit from insurance-backed guarantees for total peace of mind. Whether you own a standard terrace or a non-traditional build like an Airey or Cornish unit, we provide the technical expertise required to improve your property correctly.

Improving Your EPC Rating and Reducing Bills

For many landlords and homeowners in South Wales, energy performance is a major concern. Improving your EPC rating is not just about meeting current MEES compliance regulations; it is about protecting your long-term investment and reducing your carbon footprint. By investing in professional wall insulation, you are taking a proactive step toward decarbonisation while significantly lowering your monthly heating costs. We help you transition from a cold, energy-inefficient house to a modern, thermally-sealed home that is cheaper to run and healthier to live in.

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.
