The Importance of Thermal Performance in Older Homes

Many local homes, including Victorian terraces, Edwardian villas, and solid wall cottages, were constructed without modern thermal standards in mind. These buildings often lack adequate insulation in sloping ceilings, ashler walls, and gable ends. Our team specializes in addressing these thermal gaps, ensuring a continuous thermal envelope that drastically reduces heat loss. Whether you reside in a detached home, a semi-detached property, or a bungalow, our retrofit solutions are tailored to your unique architectural requirements.

Our PAS 2030 Accredited Installation Process

As PAS 2030 accredited installers, we follow rigorous standards to ensure every project is completed safely and effectively. Our process begins with a comprehensive retrofit survey to identify specific areas of thermal bridging and necessary ventilation improvements. We install high-performance insulation boards between and over rafters and treat vertical stud walls to modern standards. Proper ventilation is critical in our work; we ensure your roof timber remains breathable to prevent interstitial condensation, which is a common issue in poorly managed insulation projects.

Improving Your EPC Rating and Energy Efficiency

For landlords and homeowners in Rhymni and Rhymney, improving room-in-roof insulation is one of the most effective methods to boost an EPC rating. By upgrading your insulation, you can often move your property from a D or E rating up to a C, which is essential for meeting modern energy standards. Beyond potential cost savings on your heating, our insulation services help prevent mould and damp, protecting the structural integrity of your home for the long term. We also provide assistance in understanding current grant availability for energy-efficiency upgrades.

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 PAS 2030 accredited room in roof insulation, EPC rating improvements, and energy efficiency retrofit services in South Wales and South West England and across South Wales.

How long does it take to insulate an attic room?

+

Most domestic projects in Ferndale take between 3 to 5 days. This includes the installation of the insulation boards, plasterboarding, and the final skimming. We work efficiently to make sure your home is back to normal as quickly as possible.

Will I lose a lot of space in my bedroom?

+

We use high-performance PIR boards which are much thinner than traditional wool insulation but offer better thermal resistance. You will typically lose about 50mm to 75mm of space on the walls and ceilings. Most customers find this loss is barely noticeable compared to the massive improvement in warmth.

Does this help with damp and mould?

+

Yes, if your damp issues are caused by condensation. Cold walls in attic rooms often attract moisture, which leads to black mould. By insulating the walls, we raise the surface temperature, which stops water vapour from turning into liquid. We also ensure that your roof continues to breathe correctly to prevent any structural timber issues.

Is there a lot of mess during the installation?

+

Insulation and plastering can be dusty, but we take great care to protect your home. We use heavy-duty drop cloths and dust sheets on all walkways and furniture. As licensed waste carriers, we also make sure all old materials and offcuts are removed from your property and disposed of legally.

Can I get a grant for this work?

+

There are various schemes like ECO4 or the Great British Insulation Scheme that sometimes cover room-in-roof insulation depending on your circumstances and your property’s current EPC rating. We can discuss your eligibility during our initial survey and point you in the right direction.
