Our approach to sustainability

Our commitment begins with responsible sourcing. We only use timber from responsibly managed, replanted forests, and more than 80% is FSC certified. We also plant a tree for every door we manufacture, helping to restore woodland and increase carbon capture. We produce doors using reclaimed barn wood and manufacture certified Passivhaus doors, supporting lower-carbon, energy-efficient buildings.

Social impact
We believe sustainability is about people as much as it is about the environment. Our doors help create warm, secure and comfortable homes while reducing energy consumption through high levels of insulation. We are proud to support local jobs, traditional craftsmanship and responsible sourcing, ensuring that our business contributes positively to both the environment and the communities we work within. Every door we make is designed to provide long-term value, giving homeowners confidence that they are investing in something built to last.

Pollution prevention and toxin reduction
Our products are designed to preserve and restore the environment. Our doors are coated exclusively with non-toxic, water-based paints. This significantly reduces harmful VOC emissions, improves indoor air quality, and minimises environmental pollution throughout production and use.Our exclusive use of water-based paints prevents emissions to air, contamination of water and soil, and supports a cleaner, safer production process. Toxin reduction is a core environmental attribute of our product line and central to our impact business model.

Tree planting
We have planted at least 500 trees in the last few years. We plant a tree for every door we make. We manufacture around 80 to 100 doors each year so we are planting more trees than the amount of timber we use. We want to replace what we use and leave a positive environmental legacy for future generations.

Investing in new machines
We have invested in two new machines, which will reduce our energy consumption, and make our workshop more efficient. Our current briquette machine will soon be replaced with a combined deduster and briquette press. This new system is aerodynamically designed, more efficient, and quieter. We estimate that the new machine will save 3.5kW per hour, which equates to around 8750kW per year. Already in use in our workshop, our new CNC machine uses less energy than the previous iteration, and enables us to make our doors 30% quicker.

Timber waste-to-energy
Wood waste is an unavoidable by-product when manufacturing timber products. We operate a comprehensive timber purchasing policy to minimise waste, and we've invested in technologies and processes to manage and use our wood waste. Using the combination of a briquette machine and our DEFRA clean air exempt biomass burner, we process all of our wood dust, shavings and offcuts. This innovative approach allows us to convert these waste materials into a valuable energy source. By using them to heat our workshop, we reduce the amount of waste sent to landfill and decrease our reliance on conventional gas energy. 

The result? A reduction of our CO2 footprint by an impressive 22.2 tonnes per year. We take pride in our commitment to environmental stewardship and strive to be at the forefront of sustainable manufacturing practices in the timber industry.

Passivhaus certified products
One of our door ranges has achieved Passivhaus certification from the Passivhaus Institute in Germany, one of the most respected energy-efficiency standards in the world. These doors feature exceptional insulation, airtight construction and minimal thermal bridging, helping homes retain heat and reduce energy use. They contribute to comfortable indoor temperatures while lowering heating demand and reducing carbon emissions. Even our standard range includes an 80mm insulated core, providing thermal performance that exceeds many conventional alternatives. 
Education and sharing knowledge
Helping customers make informed decisions is a big part of what we do. We regularly deliver CPD presentations, both online and in person, to architects, covering topics such as U-values, and thermal performance. We also produce technical articles, case studies, online features, and a biannual magazine for homeowners, architects, and property developers. Our aim is for customers to understand the product they are buying, and how to look after their door, so it serves them for many decades to come
