All Thermowood used by Swallow (GB) Ltd. Is manufactured from quality red wood pine. The process involves kiln drying the timber which is then put in a special oven where a powerful compressor removes the air. The temperature is raised to 215 degrees C which bakes the timber. The result seals the capillaries, destroys resins and proteins and stabilises the timber.

The benefits are:

  • All bacteria is killed, resulting in a sterile material

  • The timber is totally natural and chemical free

  • Reduced thermal conductivity

  • Improves durability against decay

  • Improved dimensional stability

  • Good choice for allergy sufferers

Our fantastic potting sheds

Available in two gable widths: Jay 2035mm (6’8) and Rook 2660mm (8’9). Our innovative design enables growing room to be maximised while allowing for all important storage space. Two rear shelves are supplied as standard in addition to staging at the front of the shed. To aid ventilation there is an opening end window with manual stay, and an automatic vent or vents in the roof. The roof is covered with vinyl for durability.
Under the floor runners are plastic strips to keep the timber off the ground and extend the life of the building.
