Expert Internal Wall Insulation Across South Wales

Based in Ferndale, Global Plastering provides highly efficient internal wall insulation (IWI) for properties throughout a 60-mile radius, covering South Wales and South West England. From solid wall Victorian terraces to complex commercial retrofits, our PAS 2035 compliant solutions drastically reduce heat loss, lower soaring energy bills, and instantly improve your EPC rating.

Why Choose Internal Wall Insulation for Your Somerset Home?

Many properties in Minehead suffer from heat loss through uninsulated solid walls, leading to cold surfaces, condensation, and high energy bills. Internal wall insulation involves installing high-quality insulating materials to the inside of your external walls, significantly reducing thermal bridging. This process is particularly effective for homes in conservation areas where external wall insulation may not be permitted due to planning restrictions. By choosing IWI, you retain the character of your property's exterior while achieving modern standards of thermal efficiency and lowering your monthly heating costs.

Our Professional Installation Process and PAS 2035 Compliance

Quality is at the heart of everything we do. As a PAS 2030 accredited business, we follow strict PAS 2035 retrofit standards for every installation. Our team begins with a thorough survey to assess the moisture profile and breathability needs of your walls, which is crucial for preventing damp and mould. We use industry-leading insulation materials, ensuring that every board and skim finish is applied to the highest standard. This systematic approach guarantees long-term energy performance and provides the peace of mind that your home is treated with the care it deserves.

Supporting Landlords and Commercial Property Owners in Minehead

For landlords in the South West, meeting the current Minimum Energy Efficiency Standards (MEES) is a legal necessity. Improving the EPC rating of your HMOs, flats, or rental houses is a key part of property management, and IWI is often the most practical solution. Our team understands the regulatory landscape and the importance of decarbonisation projects. We help you achieve compliance efficiently, ensuring your properties remain attractive and energy-efficient for tenants while avoiding the risks associated with non-compliant, low-rated buildings.

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."

FAQ

Frequently Asked Questions

Answers to common questions about our internal wall insulation services, heat loss solutions, and PAS 2030 compliant retrofits in South Wales and South West England.

How much space will I lose inside my rooms?

+

This is a common concern for homeowners in Ferndale. Modern high-performance insulation boards are incredibly efficient, meaning we can achieve great thermal results with relatively thin materials. You will typically lose about 60mm to 100mm on the treated walls. Most customers find this small trade-off is well worth it for a home that is significantly warmer and cheaper to run.

Will IWI cause damp or condensation in my home?

+

When installed correctly by experts like us, IWI actually helps reduce the risk of surface condensation. By warming up the internal surface of the wall, you remove the "cold spot" where moisture in the air usually settles. We use vapour control layers and ensure proper ventilation is maintained to keep your home healthy and breathable.

Can I still hang pictures and shelves on insulated walls?

+

Yes, you certainly can. While you need to be mindful of the depth of the insulation, we can advise you on the best fixings to use. For heavy items like radiators or kitchen cupboards, we plan ahead and install "pattresses" or extra timber supports behind the boards during the installation process.

Is there a lot of mess during the installation?

+

We won't sugar-coat it—any internal work involves some disruption. However, we pride ourselves on being respectful guests in your home. We cover flooring, protect your furniture, and clear away all debris. Because we are professional plasterers by trade, we ensure the finish is top-tier, leaving you with a blank canvas ready for paint.
