External Wall Insulation (EWI)

Is the outside of your home looking somewhat neglected, tied and in need of a little renovation? Does it feel cold in the winter or suffer from damp, mould or mildew? Would you like to save around £460 a year on your utility bills? If the answer is “YES”, then you really should be considering our 25 year guaranteed External Wall Insulation, which solves all three in one simple solution.

What is External Wall Insulation?

External wall insulation involves fixing a layer of insulation material to the external walls of your property. This is then covered with reinforcement and a special type of render. The final process utilises a wide choice of textured finishes, brick slips or a brick effect render to make your property look amazing. However, the real benefits are how warm your home will feel and how much money you will save on your energy bills.

Why insulate your external walls?

Due to a lack of proper insulation you could be losing up to 35%-45% of your heat through your walls. According to the Energy Savings Trust, this can result in you paying an extra £460 towards your yearly utility bills. External wall insulation – also known as solid wall insulation – can change that dramatically, not only does installing external wall insulation on your property save you money, it can also substantially transform the look of your home.

Westville utilise a number of internal and external products in the provision of our insulation work. In order to ensure we select the right methods of insulation, we consider it vital to fully understand your individual needs and your property construction. Our process always starts with an initial consultation, either over the phone or via email in the first instance. Based on this assessment we will help you make an informed choice on what solution best meets your needs. Following this we will then progress to a full survey, where we will assess your properties suitability for the different products available. The next stage is providing a guideline on price and looking at any potential insulation grants that may be available. Only when you are fully informed and happy will we arrange a suitable date for the work to be carried out.

How is the work carried out?

Our insulation process is designed to be as hassle free as possible. Following an assessment of suitability, we will agree with you an installation date convenient to both parties. Our first stage is to erect scaffolding in order to access all the relevant parts of your home. This allows our experienced installation team to lay base tracks and insulation boards, which are then covered in specialised mesh and rendered. This process can be a little dusty and noisy, however, our experienced team have all been specifically trained to minimise this disruption. This is evident in the many awards Westville have won for our customer care ethos. The final stage is to apply a finishing product, which is selected from a large choice of applications to suit your tastes, giving your property an amazing new look.
