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 Improves Your Home

Internal wall insulation involves fixing rigid insulation boards or breathable systems directly to the internal face of your external walls. This process acts as a thermal blanket, significantly reducing the amount of heat escaping through your walls. It is an ideal solution for period properties where changing the external facade is not desired or permitted. Beyond thermal benefits, our work includes meticulous skimming and dry-lining to restore a perfect finish to your rooms. We focus on modern, breathable materials that prevent moisture buildup, ensuring your home stays dry, healthy, and free from the mould issues often associated with older, poorly ventilated insulation.

Addressing Cold Walls and Damp in Older Properties

Living in a solid-wall property in Pontycymer often means dealing with cold internal wall surfaces and persistent draughts. These issues are common in both Victorian terraces and concrete-based builds like Airey or Wimpey no-fines houses. Our approach solves these problems by tackling thermal bridging, where cold spots occur at junction points in the building structure. By installing high-performance insulation, we not only raise your EPC rating but also protect your structural integrity, helping you avoid long-term damp problems and creating a stable, temperate indoor climate all year round.

Meeting PAS 2035 and MEES Compliance Standards

We take the complexity out of property energy upgrades by adhering to the latest PAS 2035 retrofit standards. For landlords and HMO owners in Bridgend, meeting current Minimum Energy Efficiency Standards (MEES) is essential for legal compliance and property valuation. Our team provides the expert assessment and quality installation required to elevate your EPC ratings effectively. By delivering projects that are fully compliant, we give you peace of mind that your investment meets all necessary regulatory requirements while making your rental or commercial properties far more attractive to occupants.

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.
