Expert Heat Loss Reduction Solutions Across South Wales

Why is your Treharris home losing heat?

Many residents in Treharris experience cold spots, draughts, and damp issues that are directly linked to inadequate insulation. Heat loss often occurs through uninsulated solid walls, roof spaces, and thermal bridging where building materials meet. These weaknesses force your heating system to work harder, leading to unnecessarily high energy bills. Our team conducts detailed assessments to pinpoint these issues, offering bespoke solutions that move beyond simple repairs to provide a comprehensive whole-house approach to energy efficiency.

Our approach to PAS 2035 retrofitting

As a PAS 2030 accredited installer, we adhere to the highest industry standards for every project. We specialise in PAS 2035 compliant retrofits, which ensures that each energy-saving measure is designed and installed for the specific requirements of your property. Whether your project requires high-performance external wall insulation, targeted internal wall insulation, or advanced loft insulation, we manage the technical complexity of the process. This rigorous approach not only increases thermal comfort but also improves your property EPC rating, essential for meeting modern energy standards.

Supporting local property types in Merthyr Tydfil

The architecture across Merthyr Tydfil requires a nuanced approach to insulation. Older homes often require breathability to prevent condensation, while non-traditional constructions demand specific materials to maintain structural integrity. Our team is experienced in working with diverse building types, ensuring that all work is completed to satisfy both thermal goals and planning requirements where applicable. We prioritise durable, long-term solutions that protect your investment and contribute to local decarbonisation efforts.

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."

G. Toogood (Bristol)

"Charlotte and the team were professional, reliable, and excellent at communicating throughout. They did a fantastic job of skimming and rendering the back of our house during our renovation. Superb quality of work and highly recommended!"

Heat Loss Reduction FAQs

Frequently Asked Questions

Expert answers to common questions regarding thermal bridging, EPC rating improvements, and our PAS 2030 accredited heat loss solutions across South Wales and South West England and South Wales.

How much money can I really save by reducing heat loss?

+

The savings depend on your property type, but for a typical uninsulated solid-wall house, installing External Wall Insulation can save you hundreds of pounds a year on your heating bills. When combined with loft insulation and draught-proofing, the savings are even more significant. Most homeowners notice the difference in their energy costs almost immediately.

What is the difference between EWI and IWI for heat loss?

+

External Wall Insulation (EWI) involves fixing insulation boards to the outside of your house and covering them with a weatherproof render. It is highly effective because it covers the entire "envelope" of the building. Internal Wall Insulation (IWI) involves fixing insulation to the inside of your walls. IWI is often used when you want to keep the original exterior look of a Victorian property or if you live in a conservation area.

How does heat loss reduction help with damp and mould?

+

Mould often grows on cold spots where warm, moist air condenses. By insulating your walls and addressing thermal bridging, we keep the internal surface of your walls much warmer. This prevents condensation from forming in the first place, which is the most effective way to stop mould growth in its tracks.

Is my home suitable for a fabric-first retrofit?

+

Almost any home can benefit from a fabric-first approach. Whether you live in a modern bungalow, a mid-century semi, or a traditional solid-stone terrace, there are always ways to improve thermal performance. We specialise in both traditional and non-traditional builds, including concrete and timber-frame homes.

What does it mean to be PAS 2030 compliant?

+

PAS 2030 is the industry standard for the installation of energy efficiency measures in existing buildings. By choosing a PAS 2030 compliant installer like us, you are ensuring that the work is done to a high technical standard, follows strict safety protocols, and is eligible for certain grants or insurance-backed guarantees.
