Expert Solid Wall Insulation Services in Llantrisant

Global Plastering is your leading specialist for solid wall insulation in Llantrisant and the surrounding Rhondda Cynon Taf region. Many local properties, particularly our classic Victorian and Edwardian terraces, lack the thermal protection found in modern builds. These solid walls act as a thermal bridge, allowing heat to escape rapidly and leading to high energy bills. Our PAS 2030 accredited team provides tailored internal and external wall insulation solutions designed to significantly improve your home's thermal efficiency and comfort.

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 Solid Wall Insulation Transforms Your Property

By applying high-performance insulation to the internal or external envelope of your property, we create a thermal barrier that keeps warmth inside during winter and maintains a cooler climate in summer. This process is essential for heat loss reduction, addressing the cold spots often found in older masonry homes. Beyond the energy savings, our professional rendering finishes provide a complete aesthetic transformation, breathing new life into tired exterior walls and protecting the fabric of your building against the elements.

Why Choose Our PAS Accredited Retrofit Services?

Quality and safety are at the core of our operations. As a company fully compliant with PAS 2035 retrofit standards, we ensure that every installation is technically sound and fit for purpose. Whether you live in a traditional terrace, a bungalow, or a non-traditional build such as an Airey or Cornish unit, we have the expertise to manage the project effectively. Furthermore, our status as a SWIGA-accredited installer means you receive valuable insurance-backed guarantees, giving you peace of mind throughout the lifespan of your new insulation.

Is My Home Suitable for Solid Wall Upgrades?

If your home was built before the 1930s, it likely has solid walls rather than cavity walls, making it a prime candidate for our specialist insulation services. We frequently assist homeowners in Llantrisant who are struggling with cold rooms, persistent damp, or rising energy costs. Landlords also turn to us to ensure their properties meet MEES compliance, as improving your EPC rating is a vital step in modernising rental assets. We take care of the technical complexities, including assessing whether planning permission is required for external work on your specific property type.

From our base in Ferndale, we provide comprehensive insulation services within a 35-mile radius, serving domestic and commercial clients throughout Llantrisant and across South Wales. Our team understands the specific architectural challenges of the local housing stock, ensuring that every project is handled with precision and care.

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.
