Why Choose Global Energy Insulation For External Wall Insulation?

How Our EWI Installation Process Works

Our insulation process is designed to be as non-intrusive as possible while delivering maximum thermal efficiency. We begin by securely fixing high-performance insulation boards to the exterior of your property, which acts as a thermal blanket to stop heat escaping. Once the boards are in place, we apply a reinforced base coat to ensure structural integrity and weather resistance. The final step is the application of a high-quality silicone or monocouche render, providing a durable, weather-proof finish that breathes new life into your home's exterior aesthetics.

Why Is EWI Recommended for Local Period and Solid Wall Properties?

Many homes in Abercynon, including Victorian terraces and non-traditional builds like Wimpey no-fines, were constructed without modern thermal standards in mind. Without proper protection, these walls act as a bridge for cold temperatures, leading to thermal bridging, persistent damp, and black mould growth. Installing EWI is one of the most effective solutions to rectify these issues, as it moves the thermal envelope to the outside of the building. This process not only keeps your home warmer in winter and cooler in summer but also protects the original structure from the elements, ensuring long-term durability and regulatory compliance.

External Wall Insulation FAQs

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited external wall insulation, EPC improvements, and heat loss reduction services in South Wales and South West England.

Do I need planning permission for external wall insulation in Ferndale?

+

In many cases, EWI falls under "permitted development," but it depends on the property. If you live in a conservation area or if the insulation significantly changes the look of your house compared to your neighbours, you might need to check with Rhondda Cynon Taf council. We can help you understand the local requirements before we start.

How long does the installation take?

+

For a standard semi-detached or terraced home, the process usually takes between 2 to 3 weeks, depending on the weather. Because all the work happens outside, there is very little disruption to your daily life.

Will EWI solve my mould problems?

+

Yes. Most mould in UK homes is caused by "cold spots" on walls where moisture in the air turns into condensation. By insulating the outside of the building, those walls stay warm, preventing the conditions that allow mould to grow.

Can I get a guarantee for the work?

+

Absolutely. We provide SWIGA-backed guarantees, which are industry-recognised and often required by mortgage lenders. This gives you long-term protection and confidence in the quality of our work.
