Why Choose Our External Wall Insulation Services Across South Wales?

Solving Cold Walls and High Energy Costs

Many older homes in Llantrisant suffer from poor thermal performance, resulting in cold walls, uncomfortable draughts, and rising heating bills. Our external wall insulation systems act as a thermal jacket for your building, preventing heat from escaping through the structure. By addressing thermal bridging at the source, we help you stabilise your indoor temperature throughout the year. This approach is particularly effective for solid wall properties and non-traditional builds like Wimpey no-fines or concrete-based structures, which are notoriously difficult to heat without professional intervention.

Is External Wall Insulation Right for Your Property

Investing in EWI is a major decision, and our team provides full transparency regarding the process and benefits. We perform thorough retrofit assessments to determine the most suitable materials and application methods for your specific building type. This process ensures your project complies with PAS 2035 standards while protecting the character of your home. If you are a landlord looking to improve your EPC rating to meet current MEES legislation, or a homeowner aiming to reduce your carbon footprint, our solution-oriented installations provide long-term reliability and noticeable improvements in thermal comfort.

Our Commitment to Quality and Compliance

As a fully PAS 2030 accredited business, we prioritise safety, quality, and regulatory compliance on every site. We maintain full public liability insurance and are licensed waste carriers, ensuring that your project is handled professionally from start to finish. Furthermore, our status as a SWIGA-accredited installer allows us to provide insurance-backed guarantees, offering you complete peace of mind. We understand the local planning landscape in Rhondda Cynon Taf, ensuring that all decorative finishes meet requirements while providing the modern, high-quality aesthetic you expect.

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!"

Expert Advice

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited external wall insulation, solid wall solutions, and energy efficiency services in South Wales and South West England and across South Wales.

Will EWI make my home look different?

+

Yes, but in a good way. You can choose from a wide range of silicone renders or even brick-slip finishes. If you live in a Victorian street, we can often match the aesthetic of the surrounding area while vastly improving the thermal performance.

How long does the installation take?

+

For a standard semi-detached house, the work usually takes between two and three weeks, depending on the weather. Because all the work happens outside, there is very little disruption to your daily life.

Do I need planning permission for external insulation?

+

In most cases, EWI falls under permitted development. However, if your home is a listed building or in a conservation area, you might need permission. We can advise you on the specific rules for your location in South Wales.

Can I get a grant for external wall insulation?

+

There are often government schemes available to help with the costs of energy efficiency improvements, especially for those in fuel poverty or living in certain postcodes. We can help you find out if there is any current funding available for your project.

Is EWI better than internal wall insulation?

+

EWI is generally preferred because it doesn't take up any floor space inside your rooms and it does a better job of covering thermal bridges (areas where heat escapes through the structure). It also protects the exterior fabric of your building from the elements.
