We recently worked with a client in Essex who wanted a traditional timber window with high energy efficiency and exceptional thermal efficiency.

For this project, our expert team at Passivlux recommended the Rationel AURA system, as it compliments their beautiful traditional property whilst providing modern standards of performance that the client requested.

The Rationel timber casement windows add a touch of elegance to the property with classic design features and a pristine white finish to complement the gorgeous rose colour of their home in Essex. Traditional properties, such as our client’s, benefit from traditional timber windows as they perfectly complement the house’s architectural details.

Timber is an excellent insulator that offers excellent thermal performance, as the client had requested. Traditional properties can get cold, so it was important that we installed high-performance timber windows to help their Essex home retain heat.

The Rationel AURA system replicated traditional timber windows that are reminiscent of the period in which the client’s home was built. They make a beautiful as well as practical addition to the traditional properties in Essex.

Our client also opted for triple glazing units to complete their new timber windows, which offer improved thermal insulation, enhanced security, and contribute towards sound reduction.

Why Choose Timber Casement Windows?

Timber casement windows are some of the most thermally effective because they are tightly sealed when shut, meaning no cold drafts can get in your home and heat is retained inside. This makes them the perfect solution for more traditional properties that you struggle to keep warm.

This means that you could reduce your household energy consumption by relying less on central heating. Most of the UK’s largest carbon emissions come from heating, lighting, and using homes, so installing energy-efficient windows can help reduce your carbon footprint.

You can also help the environment by installing Rationel sustainably sourced timber windows because they are 100% recyclable, it is a renewable material, and it can help reduce carbon.

The benefit of having custom-made windows is that you can customise them to suit your home. Our client in Essex a more traditional property, so they opted for more traditional colours and glazing options. However, there are several ways you can make your windows bespoke.
