Why Choose Global Energy Insulation For External Wall Insulation?

How Our EWI Process Improves Your Property

Our installation process is thorough, focusing on a whole-house retrofit approach. We begin by attaching high-performance insulation boards directly to the exterior of your walls, which effectively eliminates thermal bridging. Once the boards are secure, we apply a reinforced base coat, followed by a durable, weather-resistant silicone or monocouche render. This not only boosts the thermal retention of your home but also provides a fresh, modern aesthetic that protects the building fabric from the wet Welsh weather. By sealing the envelope of your property, we significantly reduce heat loss and prevent the damp and condensation issues that often plague older, uninsulated homes.

Why Invest in Solid Wall Insulation?

Upgrading to external insulation is one of the most effective ways to slash your energy bills. For landlords, it is a crucial step toward meeting MEES compliance and improving your EPC rating, ensuring your rentals remain marketable and efficient. Beyond energy savings, our systems help resolve persistent issues with mould and black spot growth caused by cold walls. Our services cover all property types, including Victorian solid-wall homes and non-traditional builds like Wimpey no-fines. Partnering with our sister company, Global Plastering, allows us to provide a comprehensive end-to-end service, ensuring every detail of your home improvement is finished to a professional standard.

As a PAS 2035 accredited contractor, we handle all necessary building regulation requirements and local authority planning considerations for you.

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.
