PAS 2030 Accredited Insulation & Rendering Specialists
Across South Wales & South West England
Transforming cold homes, solid walls, and commercial properties with expert EWI, IWI, and premium silicone rendering. Lower your energy bills and improve your EPC rating today.

We specialise in high-performance external wall insulation (EWI) and specialist rendering finishes, including silicone, K Rend, monocouche, and traditional sand and cement systems. These modern exterior solutions do far more than just refresh the look of your home; they wrap the outer structure in a continuous protective layer that stops heat from escaping.

Whether your property is a traditional solid-wall Victorian terrace, a suburban semi-detached home, or a non-traditional concrete build such as a Cornish or Airey unit, our specialist EWI installations are tailored to its exact structural needs. By choosing a high-quality silicone render finish, you also protect your masonry from driving rain while giving your property an attractive, low-maintenance aesthetic.

Many older homes and commercial buildings in our damp regional climate struggle with condensation, cold bridging, and mould growth. Our comprehensive retrofitting services, fully compliant with PAS 2035 standards, are designed to address these problematic damp and thermal issues at their root cause.

We work closely with private landlords to upgrade HMOs and rental properties, ensuring compliance with Minimum Energy Efficiency Standards (MEES) and achieving significant EPC rating improvements. From internal wall dry lining to loft insulation and large-scale local decarbonisation projects, we handle the entire process with care and technical expertise.

While we are leaders in modern energy-efficiency retrofits, our roots are firmly established in professional plastering. We offer a comprehensive range of internal services, including traditional skimming, dry lining, partition wall installation, and safe artex removal.

If you are renovating an older property, repairing historic plaster, or completing the finishing touches after internal wall insulation, our skilled Ferndale plasterers deliver a flawless, perfectly smooth finish. We take pride in our clean, tidy workmanship, ensuring your living spaces are left ready for immediate painting or decorating.

Investing in wall insulation and rendering is a significant step, which is why working with a fully accredited, established contractor is vital. Global Plastering is a PAS 2030 accredited installer and a registered SWIGA member, enabling us to provide robust, insurance-backed guarantees on our external wall insulation work.

Our business (Company No: 05875199) is fully insured, CHAS accredited, and registered as a licensed waste carrier, ensuring that all old materials are disposed of responsibly. This commitment to compliance, quality control, and customer care gives you absolute peace of mind that your property is in safe, professional hands.
