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 Home?

Many older homes in Clevedon suffer from significant heat loss through uninsulated solid walls. Internal wall insulation is a highly effective solution for improving your home thermal comfort without altering the exterior aesthetic, making it an excellent choice for homes in conservation areas or those with historical features. Beyond the immediate boost in warmth, our IWI systems help prevent condensation and damp issues, creating a healthier indoor climate. Whether you own a detached house, a bungalow, or an apartment, upgrading your walls can lead to a noticeable reduction in your monthly energy bills and a improved EPC rating, which adds long-term value to your property.

How Our PAS 2035 Compliant Installation Works

At Global Plastering, we pride ourselves on being fully PAS 2030 accredited and following strict PAS 2035 retrofit standards. Our process begins with a detailed assessment of your property to ensure the chosen insulation system is perfectly suited to your wall type. We meticulously prepare your walls, install the thermal boards, and finish with professional skimming and dry-lining to ensure a seamless, smooth surface ready for decoration. Our technicians are experienced in handling complex builds, including Airey and Cornish units, ensuring that every installation is completed with the highest level of craftsmanship and technical precision.

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.
