PAS 2030 Accredited IWI Installers

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 Llantwit Major home?

Many older homes throughout Llantwit Major and the surrounding Vale of Glamorgan were built without modern insulation standards, leading to high energy bills and persistent condensation issues. Internal wall insulation is a highly effective remedy for these properties, especially when external alterations are restricted by planning permissions or conservation requirements. By fitting high-performance thermal boards and vapour control layers, we create a thermal envelope that keeps heat inside, lowering your energy consumption and potentially improving your home's EPC rating.

Our professional installation process

We take a systematic approach to every project, ensuring that your home receives the care it deserves. The process begins with a technical assessment to ensure your property is suitable for IWI and that we meet all PAS 2035 retrofit standards. Our experienced technicians then carefully install the insulation boards, ensuring a seamless fit around electrical sockets and fittings. The final stage involves expert plastering and skimming, leaving your walls with a smooth, durable finish that is ready for decorating while providing long-term thermal benefits.

Compliance and quality assurance for your peace of mind

Trust is at the core of our business, which is why we are fully CHAS accredited and adhere strictly to industry-leading PAS 2030 and PAS 2035 standards.

All our work is backed by insurance-backed guarantees through SWIGA, ensuring that your investment is protected by one of the most respected names in the insulation sector.

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)

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.
