PRESSURE TREATED TIMBER: Pressure treatment is a lifetime preservative treatment. The preservative is forced deep into the timber under pressure in a vacuum and penetrates below the surface. All other treatments apply a coat of stain to the surface of the timber only. With pressure impregnated timber, the chemicals are permanently bonded to the cell structure of the wood at a molecular level. Tanalith E is a widely used water based version so pressure treated wood is often described as tanalised. Pressure treated wood is almost colourless except for a slight green tint caused by the copper content in the preservative. No further preservative treatment is ever needed. However, if you want a coloured finish you can paint over pressure treated or tanalised wood with normal wood preservative in any colour.

BASE PLINTH: This greenhouse requires a base plinth which can be built with timber, concrete or brick. The pressure treated timber base plinth is quick and easy to assemble with substantial timber beams. The base plinth is the only part of the greenhouse which is in contact with the ground. It is best to prepare a perimeter footing for the base plinth to stand on. Concrete or paving slabs are ideal but plastic bases are also very effective with a timber base plinth. The quick draining plastic pavers will extend the life of the timber beams. Otherwise, with care the base beams can be placed on any surface including soil or gravel provided that the ground is flat and level.

TOUGHENED GLASS: Toughened glass is the best glazing material for use in greenhouses. It is around 6 times stronger than normal glass so it is less likely to break and when it does break toughened glass breaks into harmless small pieces. This makes toughened glass the best option for all the family including children, pets and the elderly. Toughened glass also strengthens the frame and it is heavy which helps to resist wind. Full height toughened glass is supplied in larger sizes than horticultural glass with no overlapping glass. All glass supplied is 4mm thick toughened safety glass to BS6206 Class A.

RESTRICTED ACCESS: This greenhouse is easy to deliver if access is restricted - all sections are designed to pass through a normal single door.

GREENHOUSE LOCATION: Ideally your greenhouse should have a clear space at least 18" wide on all sides, if possible. This ensures easy access for both installation and future maintenance. In reality this is often not practical and at many sites it is not needed. A reduced clearance is often possible on one or two sides. You should cut back or remove any nearby shrubs and trees. Remember to allow for future growth. Ideally the ridge of a greenhouse should run from east to west. The best position for a freestanding greenhouse is a sunny spot outside the shadow of nearby buildings and trees. A sheltered position is best otherwise additional screening may be advisable. Plants need plenty of water so your greenhouse should be close to a water supply and the site should be well drained.

OCTAGONAL BUILDING SIZES: For ease of reference these octagonal greenhouses are measured as a rectangle. The first dimension listed is the overall width from side to side and the second dimension is the depth from front to back. The external wall sizes are listed alongside the price. These sizes do not include the roof overhang. Many other suppliers quote the overall roof size which is much larger.
