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.

How Internal Wall Insulation Transforms Your Home

Internal wall insulation involves applying high-performance thermal materials to the inner surface of your exterior walls. This process is particularly effective for solid-wall properties where external wall insulation may not be feasible due to planning restrictions or architectural features. By creating a thermal barrier, we help you reduce heat loss, keep your home warmer for longer during the colder months, and lower your overall energy bills. Once the insulation is installed, our skilled team completes the work with professional dry-lining and skimming for a flawless finish.

Why PAS 2035 Compliance Matters for Your Retrofit

Energy efficiency is not just about adding insulation; it is about doing it right. As a PAS 2030 accredited company, we strictly adhere to PAS 2035 retrofit standards on every project. This approach ensures that your home is assessed holistically to prevent issues like interstitial condensation or poor ventilation, which can arise from incorrect installations. Whether you are looking to boost your EPC rating or improve the living conditions of a rental property, our professional team ensures your project is compliant, safe, and built to last.

Is Internal Wall Insulation Right for My Property?

Many homeowners in Nailsea ask if their property is suitable for IWI. It is an excellent choice for stone or brick buildings where you want to maintain the original external character while significantly upgrading thermal efficiency. We have extensive experience working across various building types, from detached houses and bungalows to flats and apartments. If your home has solid walls and feels consistently cold, our insulation solutions can provide the thermal performance needed to meet modern comfort standards.

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.
