Expert internal wall insulation for Maesteg homes

If you live in a characterful Victorian terrace or a classic detached property in Maesteg, you may have noticed that your walls feel permanently cold to the touch. Many older homes in the Bridgend area suffer from high heat loss due to solid wall construction, which can make staying warm during the winter an expensive challenge. At Global Plastering, we specialise in high-performance internal wall insulation designed to transform the thermal comfort of your home while preserving its exterior character. As PAS 2030 and PAS 2035 compliant installers, we help homeowners across South Wales improve their EPC ratings and reduce monthly energy bills through professional, breathable insulation solutions.

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 solid wall property?

For homes where external insulation is not a viable option, such as those with period features or conservation restrictions, our internal wall insulation provides the perfect remedy. By adding a layer of high-quality, moisture-resistant insulation to your interior walls, we effectively stop thermal bridging and prevent the cold dampness that often leads to mould growth. This process is particularly effective for non-traditional builds like Airey or Wimpey no-fines houses, which require specialist knowledge to treat correctly. Our approach ensures your living space remains warm and dry without compromising the structural integrity of your building.

What is the process for installing insulation in your home?

We begin every project with a thorough retrofit assessment to understand the specific needs of your property. Our skilled team then carefully prepares your walls, ensuring any existing plaster is sound or dry-lined to the correct standard. We install high-performance, breathable insulation boards that are tailored to the dimensions of your room. The final stage involves expert skimming and plastering, providing a smooth, high-quality finish that is ready for decoration. Throughout the entire process, we maintain strict adherence to PAS 2035 standards to ensure your home benefits from maximum energy efficiency and safety.

Helping local landlords and homeowners meet energy standards

With increasing pressure on property owners to meet Minimum Energy Efficiency Standards, our services are vital for those managing HMOs or rental portfolios in Maesteg and the wider Bridgend area.

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.
