Why Choose Global Energy Insulation for Insulated Render Systems?

Why choose external wall insulation for your home?

Many properties in the Rhisga and Risca area suffer from heat loss due to solid walls or lack of adequate thermal protection. Our external wall insulation systems act as a thermal blanket, significantly reducing thermal bridging and eliminating the damp conditions caused by cold internal wall surfaces. By improving your EPC rating, you not only increase the value of your property but also ensure your home remains warm during the coldest months. This is a critical step for landlords needing to meet MEES regulations for rental compliance.

Our installation process for Rhisga and Risca properties

We follow strict industry standards, starting with a professional retrofit assessment to ensure your project complies with PAS 2035 guidelines. Our team installs high-performance insulation boards followed by a durable, breathable render finish. We specialise in premium silicone and monocouche renders that provide a clean, modern look while resisting the unpredictable Welsh weather. As part of our commitment to quality, we work alongside our sister company, Global Plastering, to ensure that every internal and external detail is finished to an exceptional standard.

Can we improve the energy efficiency of non-traditional homes?

Yes, we have extensive experience working on various construction types, including Wimpey no-fines, concrete, and Cornish unit properties commonly found throughout South Wales. These homes often require specialised thermal solutions, and our PAS 2030 accredited team knows exactly how to enhance them for modern efficiency. By using materials that allow the building to breathe while keeping heat trapped inside, we help protect the structural integrity of your home while slashing your energy consumption.

Quality and safety are at the core of everything we do at Global Energy Insulation. We hold CHAS accreditation and are fully insured, giving you total peace of mind throughout the project.

FAQ

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited insulated render systems, stopping thermal bridging, and upgrading home energy efficiency with external wall insulation (EWI) in South Wales and South West England and across South Wales.

Will an insulated render system stop the damp in my house?

+

Yes. Most damp in UK homes is actually condensation caused by "cold bridges" on the walls. By insulating the outside of the building, the internal walls stay warm, which prevents moisture in the air from turning into water droplets and mould.

How long does the installation take?

+

For a standard semi-detached house, the process usually takes between 2 to 3 weeks, depending on the weather. Because it is an external process, there is very little disruption to your daily life inside the house.

Do I need planning permission for External Wall Insulation?

+

In many cases, EWI falls under "Permitted Development." However, if you are changing the appearance of the house significantly, or if you live in a conservation area or a listed building, you might need it. We help you navigate these local authority requirements to keep everything above board.

What is the difference between Silicone Render and K Rend?

+

K Rend is a brand that produces various types of render, including Monocouche. Silicone render is a specific type of finish that is highly breathable and water-repellent. It stays cleaner for longer because dirt struggles to grip the surface, and it is less likely to crack because it stays flexible.
