Whether you’re a one man band embarking on your first extension, or a senior buyer for one of the big house builders, it makes perfect sense to only want to use sustainable roofing timbers. With growing concerns about climate change and environmental conservation, it is imperative to choose durable and eco-friendly materials. In this blog, we will discuss the significance of using roofing timbers certified by the Programme for the Endorsement of Forest Certification (PEFC), and why we will only use them in our products. We’ll explore how PEFC certified sustainable roofing timbers enhance weatherproofing, longevity, and sustainability, along with other important considerations you should think about when choosing a roofing timbers supplier.

Weatherproofing your roofing timbers

Roof trusses, attic trusses, and floor joists made of sustainable roofing timbers play a vital role in weatherproofing a building. PEFC certified timbers sourced from responsibly managed forests are well-suited to withstand harsh weather conditions, ensuring you have a robust and secure structure that stands the test of time. The certification minimises the risk of warping, rotting, or other weather-related damages, because the quality of the wood has been guaranteed.


Investing in roof trusses, attic trusses, and floor joists crafted from PEFC certified sustainable roofing timbers guarantees longevity. Sustainable timbers undergo treatment and kiln-drying processes that enhance their durability. They provide excellent structural integrity, minimising the need for frequent repairs or replacements. This contributes to the long-term cost-effectiveness of the building, as the sturdy frame ensures enhanced stability for years to come.


Using PEFC certified sustainable roofing timbers benefits not only the immediate project that you’re working on, but also helps preserve our environment for future generations. These timbers are sourced from responsibly managed forests that adhere to strict environmental standards. The PEFC certification ensures that timbers used in construction are harvested from forests that consider biodiversity, ecosystem preservation, and respect for indigenous rights. By selecting PEFC certified timbers, builders contribute to mitigating deforestation and promoting sustainable practices in the forestry sector. Win, win.

Beyond the environmental impact, the use of sustainable roofing timbers positively affects the health and well-being of the occupants of your property. Certified timber materials are non-toxic and free from harmful chemicals, ensuring a healthy indoor environment. This feature is particularly important for attics and floors, where inhabitants spend considerable time.

Energy Efficiency

Building with roof trusses, attic trusses, and floor joists made of PEFC certified sustainable roofing timbers also contributes to improved energy efficiency. Timber possesses excellent insulation properties, reducing heat transfer and enhancing thermal performance. This reduces the need for excessive heating or cooling, resulting in lower energy consumption and utility bills. The energy required to manufacture timber products is significantly lower compared to conventional construction materials, making it an eco-conscious choice.

Choosing roof trusses, attic trusses, and floor joists made of PEFC certified sustainable roofing timbers benefits both the construction industry and the environment. By prioritising weatherproofing, longevity, and sustainability, builders can construct durable and eco-friendly structures. When we use sustainable roofing timbers, we’re ensuring structural integrity. We’re also promoting responsible forest management practices, minimising waste, and reducing the overall carbon footprint of the construction process. 

The energy efficiency and health benefits associated with certified sustainable roofing timbers further emphasise their importance. As we move towards a greener future, it is crucial for the industry to prioritise using sustainable materials. They need to not only meet construction standards, but also contribute to a more sustainable world. This is why we’re taking steps to make sure we set the standard for sustainable building practices in the UK.
