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 IWI for your solid wall property?

Many properties across South Wales, particularly Victorian terraces and mid-century builds like Airey or Wimpey no-fines houses, were built without adequate thermal protection. Internal Wall Insulation acts as a thermal blanket, significantly reducing the heat escaping through your walls. By addressing thermal bridging at the source, our system helps you maintain a consistent indoor temperature, which can lead to substantial reductions in your monthly energy bills. Furthermore, improving your property's thermal performance is one of the most effective ways to boost your EPC rating and ensure compliance with the latest MEES regulations for landlords and HMO owners.

How we manage your insulation and retrofit project

As PAS 2030 and PAS 2035 accredited professionals, we follow a rigorous process to ensure every installation is safe and effective. It begins with a professional retrofit assessment to understand the specific moisture profile and thermal needs of your Pencoed home. Our team installs high-performance, breathable insulation systems designed to prevent interstitial condensation and damp. We finish the process with high-quality dry-lining and expert plastering, leaving your walls smooth and ready for decoration. This end-to-end approach ensures your home not only feels warmer but also maintains its structural integrity for years to come.

Protecting your home with accredited installation

Quality and trust are at the heart of everything we do. Because we are fully PAS accredited and registered, our work is eligible for SWIGA insurance-backed guarantees, providing you with long-term peace of mind.

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.
