Expert Heat Loss Reduction Solutions Across South Wales

Why is my home losing heat so quickly?

Many older properties in the Hay-On-Wye area suffer from thermal bridging, where heat escapes through structural elements like walls, floors, and roof joints. In Victorian and Edwardian buildings, the lack of modern insulation in solid walls is a primary culprit for heat loss. Even in newer builds, gaps in loft insulation or poorly sealed window frames can lead to significant energy waste. Our specialists use advanced diagnostic methods to pinpoint exactly where your home is losing warmth, allowing us to implement targeted fixes rather than generic, inefficient repairs.

Our Comprehensive Approach to Energy Efficiency

We take a whole-house approach to retrofitting, ensuring that every improvement works in harmony. For properties with solid walls, we offer external wall insulation and internal dry-lining to create a continuous thermal envelope. If your roof space is poorly protected, our high-performance loft insulation upgrades will prevent heat from rising through your ceilings. We also specialise in addressing non-traditional building types, such as Airey or Cornish units, which often require unique, technically sound methods to meet modern energy standards. Every project is handled with a commitment to PAS 2035 retrofit standards, guaranteeing high-quality, long-lasting results.

Compliance and Quality for Powys Property Owners

Navigating the requirements for energy efficiency can be complex, especially when considering planning permissions for listed or conservation-area buildings in Y Gelli Gandryll. Our team is fully versed in current regulations, ensuring that your home not only becomes warmer but also achieves the necessary EPC rating upgrades to meet modern standards. All our installations are fully insured and backed by SWIGA guarantees, providing you with total peace of mind regarding the longevity and performance of our work. We take pride in our status as licensed waste carriers, ensuring that every project is managed cleanly, legally, and professionally from start to finish.

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.
