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.

Should I Choose Internal or External Wall Insulation for My Home?

Selecting the right insulation method depends on your building type and your specific renovation goals. External Wall Insulation, or EWI, involves fixing a thermal layer to the outside of your property, which is then finished with high-quality rendering. This method is excellent for upgrading the appearance of older houses while providing a continuous barrier against the elements. Alternatively, Internal Wall Insulation, or IWI, is ideal when the exterior character of your home must be preserved or when external access is restricted. Both methods are highly effective at eliminating cold spots, preventing damp and condensation, and significantly lowering your heating costs.

PAS 2035 Compliance and Retrofit Excellence

We take a professional, evidence-based approach to every project we undertake. By adhering to PAS 2035 retrofit standards, our team ensures that the work is not only effective but also legally compliant and structurally sound. Whether you are managing a modern flat or a historic building that requires careful handling, our PAS 2030 accredited installation process guarantees a high standard of finish. We understand the unique needs of various building types, from no-fines concrete houses to traditional masonry, ensuring your property is treated with the technical expertise it deserves.

Transforming Your EPC Rating and Property Value

Improving your home's thermal performance does more than just keep you warm; it is a vital step in enhancing your property's overall energy efficiency and EPC rating. For landlords in Llantwit Major, meeting the latest Minimum Energy Efficiency Standards (MEES) is critical for compliance. By investing in our professional solid wall insulation, you are taking a proactive step towards long-term decarbonisation and property value growth. With our SWIGA insurance-backed guarantees, you have total peace of mind that your home improvement is protected and installed to the highest industry specifications.

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.
