External Wall Insulation (EWI)

Looking for a more energy-efficient, warmer and comfortable home? External Wall Insulation (EWI) is an effective way to improve the thermal performance of your property while transforming and protecting its exterior.

External wall insulation involves installing a layer of high-performance insulation to the outside of your property's walls before applying a protective render finish. By adding insulation externally, EWI helps reduce heat loss through the walls, making it easier to keep your home warmer in winter and potentially reducing the amount of energy needed to heat it.

As well as improving your home's energy efficiency, an EWI system can help reduce cold spots and improve overall comfort. It can also give an older or tired-looking property a complete exterior transformation, with a choice of modern render finishes, colours and textures to create a fresh, attractive appearance.

At Rendervate, we specialise in professionally installed external wall insulation systems across Leeds, Harrogate, York and North Yorkshire. We can help you choose the right insulation and render system for your property, combining improved thermal performance with a durable, high-quality external finish.

Benefits of EWI

Improve Energy Efficiency

External wall insulation helps reduce heat loss through your property's walls, making it easier to maintain a comfortable temperature inside your home. By improving the thermal performance of your external walls, EWI can help reduce your reliance on heating and improve the overall energy efficiency of your property.

A Warmer, More Comfortable Home

By adding a layer of insulation to the outside of your walls, EWI helps keep heat inside during the colder months. It can also help reduce cold spots and draughts, creating a warmer and more comfortable living environment throughout the year.

Protect & Transform Your Home

External wall insulation not only improves thermal performance but also provides an opportunity to completely transform the exterior of your property. The insulation is finished with a durable render system, helping protect your walls from the elements while giving your home a fresh, modern appearance.

We'll meet you at your property to discuss your project in detail. During the consultation, we'll talk you through the most suitable rendering options, answer any questions you may have and gather all the information needed to prepare your detailed quotation.

STEP 1

Complete our enquiry form and tell us a little about your project. This gives us a better understanding of your property, your requirements and your goals, allowing us to arrive fully prepared for our initial consultation.

On the agreed start date, the scaffold is erected and materials are delivered to your property. Our team will then commence the installation, following the agreed specification with care, precision and attention to detail from day one.

We'll send you a detailed quotation outlining the proposed works, materials and costs. Once you're happy to proceed, simply accept the quotation, pay the deposit and we'll schedule your project to suit your agreed start date.
