All Swallow Greenhouse comes fitted with 3mm thick Toughened Glass, the glass is slid into a groove and sealed with a quality silicone. The glass shapes are joined with a clear plastic H-Section (clean looking and easy to wipe)
Swallow use redwood pine which is thermally modified and the boards are fixed with stainless steel nails. The process involves kiln drying the timber which is then put in 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.
Benefits: It can be left untreated - All bacteria is killed, resulting in a sterile material - paints excellently and lasts up to 3 times longer - timber is totally natural and chemical free - reduced thermal conductiviy - consistent colour throughout - improves durability against decay - improved dimesnional stability - good choice for allergy sufferers.
Inward opening with a mortice lock and handle.
Each roof vent comes as standard with an bayliss automatic opener.
Bottom of Greenhouse
There is a 24mm plastic section fixed around the bottom of the greenhouse. This keeps the timber off the ground, prolonging the life of the building.
