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 Blaenau Gwent property

Many Victorian terraces and stone-built cottages in Blaenau Gwent suffer from significant heat loss because they lack modern insulation. Installing internal wall insulation is an ideal solution when external rendering or cladding is not an option, perhaps due to planning restrictions or the desire to maintain a traditional stone exterior. Our professional team at Global Plastering provides expert installation that significantly improves your home's thermal comfort, eliminates cold wall spots, and helps prevent damp by maintaining a consistent wall surface temperature.

How we improve your EPC rating and energy efficiency

Improving your property's energy performance certificate (EPC) is more important than ever, particularly for landlords needing to meet MEES regulations. Our IWI systems are a proven way to boost your rating by tackling thermal bridging at the source. As a PAS 2030 accredited company, we ensure that every retrofitting project is carried out to the highest industry standards. We don't just add insulation; we complete the process with high-quality plastering and dry-lining, ensuring your walls are finished to a perfect, smooth standard ready for decoration.

The Global Plastering installation process for Abertillery residents

We begin every project with a detailed property survey to understand the specific needs of your home. Whether you live in an end-of-terrace house or a semi-detached property, our technicians carefully prepare the wall surfaces, apply the insulation boards, and finish with professional plastering to restore your room's aesthetic. Our approach is clean, efficient, and tailored to the unique characteristics of Welsh homes, ensuring minimal disruption to your daily life while delivering long-lasting thermal benefits.

Do you need help with cold walls and high energy bills

If your home in Abertillery feels impossible to keep warm, you are certainly not alone. Many local residents find that despite running their heating, the cold radiates from the walls, leading to high bills and uncomfortable living spaces. Our team offers expert guidance on whether internal wall insulation is the right fit for your specific building type. With our SWIGA-backed guarantees and commitment to excellence, you can trust our local experts to provide a durable, energy-saving solution.

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.
