Drying kilns play an essential role in the fencing industry, helping to ensure optimum preservative penetration into timber to meet UC4 standards.
UC4 is the British Standard for timber used in permanent ground contact, such as fence posts, sleepers, and decking joists.
By reducing the fibre saturation point of timber, our kilns enable correct chemical penetration during treatment, improving the longevity and stability of each post.
The benefits include:

Every GlenFarrow kiln is fully designed and manufactured in the UK, built to suit your site, capacity, and production requirements. Our control systems are versatile and can be pre-programmed with drying “recipes” for different wood species, ensuring the correct moisture content every time.
Our kilns can be powered by your preferred energy source, including biomass-heated systems for sustainable, low-cost operation. They also offer optional remote monitoring for performance tracking.
With over 40 years’ of experience designing commercial drying kilns, GlenFarrow systems are trusted across the UK fencing and timber sectors. Each installation is backed by full project management, training, and ongoing servicing to ensure consistent performance.
Our fence post drying kilns help businesses produce kiln-dried fence posts that exceed treatment standards, reduce waste, and deliver superior quality to customers.
