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 Vale of Glamorgan home?

Many properties in Barri / Barry, particularly Victorian and Edwardian terraces, suffer from poor thermal performance due to solid masonry walls. External wall insulation is not always an option due to planning constraints in conservation areas or the desire to keep your original brickwork aesthetic intact. Internal wall insulation offers the perfect solution. It works by creating a thermal envelope inside your home, which helps eliminate condensation and damp issues while drastically improving your property's EPC rating. This is an excellent way to lower your monthly heating bills and comply with modern energy efficiency standards.

Our PAS 2035 compliant installation process

Quality and compliance are at the heart of everything we do at Global Plastering. Our installation process follows strict PAS 2035 retrofit standards, ensuring that every project is assessed correctly for breathability and moisture management. We begin with a comprehensive technical survey of your home to determine the best insulation materials for your wall type. Our skilled team then installs premium thermal boards and vapour control layers with precision. The final stage is a professional skim finish, leaving your walls perfectly smooth, painted, and ready for you to enjoy a much warmer home immediately.

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.
