Professional Solid Wall Insulation in Ystrad Mynach

If you live in a period home or a property built with solid walls in Ystrad Mynach or across the wider Caerphilly area, you may have noticed that your house struggles to hold onto heat during the colder months. Traditional solid wall construction, common in Victorian and Edwardian properties, acts as a heat sink, allowing warmth to escape directly through the masonry. At Global Plastering, we provide expert solid wall insulation solutions designed to transform the thermal performance of your home, significantly reducing heat loss and lowering your energy bills.

Why Choose Us for Solid Wall Insulation?

Based in Ferndale and covering South Wales and South West England, Global Plastering is your trusted local partner for tackling cold, hard-to-heat homes. Whether you need External Wall Insulation (EWI) to transform a solid brick property or Internal Wall Insulation (IWI) to preserve a historic Victorian façade, our fully guaranteed retrofit services eliminate thermal bridging, lock in heat, and dramatically improve your EPC rating.

Understanding Your Insulation Options: EWI and IWI

Choosing the right method for your property is key to a successful retrofit. External Wall Insulation (EWI) involves applying high-performance insulation boards to the outside of your property, which are then finished with a durable, weather-resistant silicone render. This not only traps heat inside but also provides an aesthetic facelift and protects your brickwork. For those where exterior alterations are not suitable, we offer Internal Wall Insulation (IWI) through professional dry-lining techniques. This process ensures your internal space remains comfortable while minimising thermal bridging and cold spots on your walls.

Specialised Solutions for Non-Traditional Builds

Ystrad Mynach and the surrounding Caerphilly region feature a variety of building types, including non-traditional constructions such as Airey homes, Cornish units, and Wimpey no-fines properties. These structures present unique challenges regarding energy efficiency and structural integrity. Our team is highly experienced in delivering tailored retrofit services for these specific building types, ensuring that all work complies with the rigorous PAS 2035 standards. We focus on effective moisture management and long-term durability to keep your home healthy and efficient.

Why Partner with a PAS 2030 Accredited Installer?

Energy efficiency upgrades are a significant investment, and quality assurance is paramount. As a fully PAS 2030 accredited company, we follow strict national standards for all insulation and rendering projects. We are proud to be SWIGA-accredited, meaning we can provide comprehensive 25-year insurance-backed guarantees for our external insulation work. Whether you are looking to boost your EPC rating for a sale or simply want to create a warmer environment, our CHAS accredited team ensures that your project is handled with the highest level of professionalism and care.

Can Solid Wall Insulation Help with Landlord Compliance?

For landlords in Ystrad Mynach and across South Wales, meeting Minimum Energy Efficiency Standards (MEES) is essential for property management. If your rental property currently has an EPC rating below the legal threshold, improving the thermal efficiency of solid walls is often the most effective route to compliance. We work closely with property owners to deliver efficient, code-compliant insulation that protects your asset from damp and mould while ensuring it meets modern housing regulations. Our team is ready to discuss how we can help you achieve the required energy performance certification.

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!"

FAQ

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited solid wall insulation, EWI solutions, and retrofit services in South Wales and South West England and across South Wales.

Does solid wall insulation cause damp?

+

When installed correctly by professionals like us, it actually helps prevent damp. By keeping the internal surface of the wall warmer, it stops water vapour in the air from condensing on the wall. We always make sure there is adequate ventilation as part of our PAS 2035 assessment to keep the air fresh and the walls dry.

Do I need planning permission for External Wall Insulation?

+

In many cases, EWI falls under "permitted development." However, if you live in a conservation area, a listed building, or if the insulation significantly changes the look of the front of your house, you might need permission. We can help advise you on the local rules in Rhondda Cynon Taf and beyond.

How long does the installation take?

+

For a standard semi-detached or terraced home, External Wall Insulation usually takes between 2 to 3 weeks, depending on the weather. Internal insulation can be faster but depends on how many rooms you are doing at once. We always aim to keep the workspace tidy and the disruption to a minimum.

Is it worth the investment?

+

Solid wall houses lose about twice as much heat as those with cavity walls. By insulating, you are making a long-term investment that protects the fabric of your building, slashes your carbon footprint, and saves you money every single month on your gas or electric bills.
