Sustainability Statement

At Excell Timber Windows, we place great importance on sustainability and reducing our impact on the environment. We therefore manage our business in order to create as minimal impact as we can, and to support our customers to do the same.

Direct Carbon Emissions

As a small company, our direct carbon emissions for the year ending March 2018 were 27 tonnes CO2e and come from three main sources – heating and electricity for our office and diesel in our vans.

In the year ending 2019/20 – our direct emissions were 16 tonnes CO2e – a 39% saving. 

This means we have reduced our carbon footprint by 11 tonnes per year.

Impact AreaWhat We Are Doing About It
Office Heating and ElectricityOur new timber-framed office is electrically heated by an Air Source Heat Pump – and is supplied by 100% Renewable electricity from Octopus. This therefore is zero carbon and means we are saving 10 tonnes of carbon per year.
Van FuelOur fleet of vans all comply with Euro 5 diesel emissions standards, the most efficient available at the time of purchase. 

Our aim over the next 5 years is to replace our diesel vans with electric ones. Current options for these are not suited to our requirements and are too expensive – but we are continuing to undertake research in this area and am confident the technology will catch up with our requirements. 

The 370 windows we installed in 2018 contain an estimated 34 metres cubed (m3) of timber. 1 m3 sequesters 1 tonne Carbon on average, so this means we are a carbon negative company – saving minus 44 tonnes each year.

We truly believe the future of building is in timber construction.

Saving Carbon
from Window Installs

By installing ‘A’ rated double-glazed timber windows & doors we are helping our customers save energy costs and reduce their own carbon footprints. In 2018 we installed 370 windows with an average area of 1.26 m2 therefore 466 m2. The Energy Saving Trust estimates a saving of £75 to £110 per year for a 3-bedroom home, so with 8 windows on average that is 46 homes, creating £3,468 – £5,060 energy costs and 18 – 27 tonnes CO2e saved. 

Targeting Zero Waste
to Landfill

Our site waste is collected by Collins Skip Hire – who current achieve 95% diversion from landfill with an aim to achieve 100% as soon as possible. In our office, we recycle all our ink cartridges and all other waste (mainly paper) is recycled. 

Supply Chain – Sequestering Carbon in Timber Windows

We source all our timber windows from George Barnsdale based in Donington Lincolnshire  where all of the timber is sourced through the FSC timber certification scheme. These schemes ensure that the sources of the timber are well managed and sustainable. By utilising well-managed timber sources, which is a natural way to sequester carbon we are helping to reduce the carbon in the atmosphere.

Why choose wooden windows & doors?

The quality and engineering of wooden windows and doors in the UK has undergone a revolution over the past decade. As a member of the Wood Window Alliance (WWA) we have been part of these developments.

The Wood Window Alliance ensures that its members’ windows and doors consistently meet exacting standards, are easy to maintain and provide peace-of-mind through long-life guarantees.

So why should you choose wood? Wooden windows and doors bring beauty and warmth to properties, are an environmentally friendly building material and positively contribute to health and wellbeing. At Excell Timber Windows, we only use timber that has been sourced responsibly through either the FSC® or PEFC™ chain of custody certification schemes.
