Why Choose Our External Wall Insulation Services Across South Wales?

Solving Heat Loss and Thermal Issues in the Vale of Glamorgan

Many homes in the Vale of Glamorgan suffer from significant heat loss through solid walls, which lack the cavity insulation found in more modern houses. Our external wall insulation systems act as a thermal blanket, trapping heat inside your home during the colder months. By addressing thermal bridging and cold spots, we significantly improve your indoor comfort levels and help reduce your monthly heating costs. This is an essential step for any homeowner looking to improve their property's energy efficiency and EPC rating.

How Our PAS 2035 Compliant Installation Process Works

We pride ourselves on our meticulous, professional approach to every retrofit project. As PAS 2030 accredited specialists, we follow strict PAS 2035 standards to ensure that your home is treated with the correct insulation and ventilation requirements. The process begins with a comprehensive retrofit survey to assess your property's current state. We then install high-performance insulation boards, which are finished with premium, weather-resistant renders such as silicone or K Rend. This not only boosts thermal performance but also gives your home a fresh, attractive aesthetic that can last for years.

Why Should You Trust Global Plastering with Your Retrofit Project?

Choosing a contractor for external wall insulation is a major decision, and we make it easy with our commitment to quality and transparency. As a fully insured, PAS-accredited company, we have the experience to handle both domestic and commercial projects throughout South Wales and the South West. Every installation we complete is backed by a 25-year SWIGA guarantee, providing you with total peace of mind. We are also registered waste carriers, ensuring that all aspects of your project are handled responsibly and in line with local environmental regulations.

Improving Your EPC Rating and Ensuring MEES Compliance

For landlords and property owners in Y Bont-Faen / Cowbridge, improving the energy performance of a building is no longer optional. With stricter Minimum Energy Efficiency Standards (MEES) in place, our EWI services are a direct solution for achieving the required EPC rating. Whether you own an HMO, a small flat, or a larger office space, our team understands the legal requirements for energy efficiency. We provide the expertise needed to help you avoid potential penalties while significantly increasing the value and appeal of your property.

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.
