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 Rhondda property?

Internal wall insulation is the perfect choice for homes where external cladding is not an option due to planning restrictions, conservation area status, or the desire to keep your original exterior brickwork. By installing high-performance insulation boards to the interior of your cold walls, we significantly reduce heat loss. This process not only makes your rooms feel warmer and more inviting but also drastically improves your EPC rating, helping you tackle rising energy costs and meet modern environmental standards.

Our PAS 2035 compliant installation process

We take a technical, systematic approach to every project to ensure long-term performance. Our team begins with a detailed survey to assess your property type, whether it is a semi-detached family home or a non-traditional build like an Airey or Cornish unit. We ensure the installation is fully compliant with PAS 2035 retrofit standards. Our experts apply the insulation boards, install vapour control layers to prevent damp and condensation, and finish the walls with professional skimming, leaving your home ready for redecoration.

Is internal wall insulation right for your home?

Many residents in Rhondda Cynon Taf ask if IWI will reduce their room space or cause damp issues. Our approach mitigates these concerns through precise design and the use of breathable materials. By managing thermal bridging and moisture movement, we ensure your building remains healthy. This is an ideal upgrade for landlords seeking to meet MEES regulations or any homeowner looking to improve their property's thermal comfort without altering the street-facing appearance.

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!"

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.
