Sustainability

North London Box Sash is a company that is dedicated to providing a sustainable approach to sash window and door fitting. We understand the importance of sustainability in today's world and are committed to doing our part in reducing our carbon footprint. Our double glazed sash windows are designed to be energy efficient, durable, and secure, which not only benefits the environment but also saves our customers money on their energy bills.

Our sash windows are made using high-quality materials that are sourced from sustainable suppliers. We ensure that all the materials we use are ethically sourced and have a minimal impact on the environment. Our team of experts work hard to ensure that every aspect of our business is as sustainable as possible, from the materials we use, to the way we operate our business. 

Commitment Towards Sustainability

At North London Box Sash, we understand the importance of sustainability in our manufacturing process. Timber, being a renewable resource, is our material of choice for our product range. We leverage the natural insulating properties of timber by coupling it with high-performance glass to offer superior insulation against heat loss. 

Our commitment to sustainability is reflected in our product range, and we were the first UK timber window and door manufacturer to produce an A rated timber window. We strive to offer the widest range of energy-rated timber products in the country. Our design philosophy is not just focused on thermal performance but also on durability, ensuring that our products require little maintenance and have a longer lifespan, leading to the recovery of production inputs many times over.

Our double glazed sash windows are designed to provide improved energy performance, which means that they help to reduce the amount of energy needed to heat or cool your home. This not only reduces your carbon footprint but also saves you money on your energy bills. In addition to this, our windows are also durable, which means that they last longer than traditional single glazed windows. This reduces the need for replacement windows, which in turn reduces waste and helps to conserve resources.

All the timber we use is ‘FSC’ Certified

As awareness about the impact of deforestation on climate change grows, choosing responsibly sourced wood has become increasingly important. This is where FSC certification comes in. FSC, or the Forest Stewardship Council, is an international non-profit organisation that sets standards for responsible forest management and certifies products that meet those standards. 

All of the timber that we use is FSC certified, which means that it comes from forests that have been responsibly managed according to FSC's strict environmental, social, and economic criteria. This includes protecting endangered species, respecting the rights of indigenous peoples, and ensuring that the forest is regenerated after logging. By choosing FSC-certified wood, we can be sure that we are not contributing to deforestation or other harmful practices.
