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 home?

Living in a solid wall property often means struggling with cold walls and high heating costs. Internal wall insulation acts as a thermal barrier, trapping heat inside your living spaces rather than letting it escape through the masonry. This process is highly effective for homes where external wall insulation may not be suitable due to planning restrictions or architectural features. Beyond thermal comfort, our insulation systems play a vital role in damp prevention and condensation control, creating a healthier indoor environment for you and your family.

Our approach to PAS 2030 compliant retrofitting

We pride ourselves on our technical expertise and commitment to quality. Every project we undertake follows rigorous PAS 2030 standards, ensuring that the installation is safe, efficient, and durable. Our team begins with a thorough survey of your property to identify areas of thermal bridging and moisture risk. We then install high-performance insulation boards finished with a professional plaster skim, ensuring that the final result is not only thermally superior but also aesthetically flawless. Whether you are retrofitting a single room or a whole house, our focus remains on long-term performance and build quality.

Improving your EPC rating and meeting MEES requirements

For landlords and property owners in Blaenau Gwent, meeting the Minimum Energy Efficiency Standards is becoming increasingly important. An improved Energy Performance Certificate rating can significantly increase the value of your property and ensure compliance with current regulations. Our internal wall insulation services are designed to provide a measurable boost to your home's thermal efficiency. By upgrading your wall insulation, you are taking a proactive step toward lower carbon emissions and a more sustainable property profile that stands up to the rigours of the Welsh climate.

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.
