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.

Improving Thermal Efficiency in Your Vale of Glamorgan Property

Does your home feel cold regardless of how high you set the heating? Solid wall properties lack a cavity, making them prone to damp, thermal bridging, and heat loss. Our PAS 2030 accredited team specialises in modern retrofit standards, helping you identify whether internal or external wall insulation is the best choice for your building. By wrapping or lining your property, we create a thermal envelope that keeps warmth inside during the winter and prevents overheating during the summer.

How Does the PAS 2035 Retrofit Process Work

Quality assurance is at the heart of everything we do. Following PAS 2035 standards, we begin with a professional assessment to understand the specific moisture and ventilation needs of your property. Whether we are applying external wall insulation to a detached house or installing discreet internal systems in an apartment, every step is handled by our expert team. We manage the entire project from the initial survey through to the final finish, ensuring your home remains compliant and energy-efficient for years to come.

The Long Term Benefits for Your Home

Investing in solid wall insulation offers more than just immediate comfort. You will notice a drastic reduction in drafts and the elimination of cold spots that often lead to mould and condensation. Furthermore, upgrading your insulation is one of the most effective ways to boost your property's EPC rating, which is essential for modern energy standards and long-term asset value. With our SWIGA insurance-backed guarantees, you can rest assured that your investment is protected and completed to the highest industry standards.

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.
