Why Choose Global Energy Insulation For External Wall Insulation?

How does EWI help solve cold house problems?

External wall insulation works by wrapping your home in a protective, thermal blanket. This process effectively eliminates thermal bridging, which is the primary cause of cold patches on internal walls and associated black mould or condensation issues. Whether you live in a Victorian terrace or a non-traditional build like an Airey house or Wimpey no-fines property, our system prevents heat from escaping through the masonry. This creates a more stable indoor temperature, meaning your boiler does not have to work as hard to keep you warm during the harsh winter months.

Expert PAS 2035 Retrofit services for your property

We pride ourselves on being a PAS 2030 accredited company, which means all our work aligns with rigorous PAS 2035 whole-house retrofit standards. This is essential for improving your home's EPC rating, especially for landlords needing to meet current MEES compliance regulations. Our team handles every aspect of the project with technical precision, ensuring that your property is not only warmer but also more durable and energy-efficient for the long term. We manage the complexity of building regulations so you do not have to worry.

Our commitment to quality and aesthetic finish

Beyond thermal performance, we understand that the appearance of your home matters. We offer a range of premium finishes to suit the character of your Swansea property, including silicone, monocouche, and K Rend. For homeowners looking to renovate both the exterior and interior, we work closely with our sister company, Global Plastering, to provide a complete, end-to-end service. This collaboration ensures that your home receives a professional finish inside and out, all coordinated by our expert team.

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.
