STRUCTURAL CILLS: This greenhouse includes low profile structural cills. A separate base plinth is not required. Structural cills are designed to suit a low threshold doorway. They are stronger than normal greenhouse cills with a lower profile than a traditional base plinth. Structural cills feature a flat underside to spread the weight of the greenhouse over a larger area. They can be placed on concrete, paving slabs, bricks or decking but structural cills should not be placed on soil or gravel.

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.

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. Polycarbonate glazing is not recommended at exposed sites. Plants need plenty of water so your greenhouse should be close to a water supply and the site should be well drained.

SIZES - LENGTH AND WIDTH: The external wall sizes are listed alongside the price. The first dimension listed is the width and the second dimension is the length. The width refers to the angled gable walls at the front and rear including the door wall. The length refers to the side walls.
