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 Your Property Needs Better Insulation

If you live in a period home or a solid-wall property, you are likely feeling the impact of high energy bills and cold internal walls. Solid walls act as a thermal bridge, allowing heat to escape rapidly in the winter months. By installing high-performance insulation, you can drastically reduce this heat loss, creating a more comfortable living environment while lowering your monthly expenditure. Beyond the financial savings, our work helps improve your property's overall EPC rating, which is essential for meeting modern decarbonisation targets and MEES compliance for rental properties.

Choosing Between External and Internal Wall Solutions

The choice between External Wall Insulation and Internal Wall Insulation depends on your property type and your specific goals. External Wall Insulation involves applying a protective, thermal layer to the outside of the building, which is then finished with durable, weather-resistant silicone rendering. This is excellent for protecting your brickwork while transforming the exterior aesthetic of your home. Internal Wall Insulation is a practical alternative for those who wish to preserve their building's original facade, particularly in conservation areas or on properties with unique architectural detailing. Our PAS 2035 accredited assessors will help you decide which method offers the best long-term outcome for your building.

Quality Assured Installation Standards

We take pride in our status as a PAS 2030 accredited installer, which means every project we undertake meets rigorous national safety and quality standards. Our work is not just about aesthetics; it is about providing long-term structural and thermal improvements. As a SWIGA-accredited company, we offer insurance-backed guarantees on our rendering and External Wall Insulation projects, providing you with total peace of mind. From the initial survey to the final finish, our team ensures that every stage of the process is handled with professional care and attention to detail.

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.
