DWARF WALLS: Dwarf walls can be built in your choice of brick or stone. You can choose engineering bricks for durability or you may be able to closely match the walls of your existing property. Dwarf walls offer maximum heat retention in the winter and are ideal for growing shade-loving plants such as ferns. Our prices do not include the dwarf walls. The greenhouse frames are prefabricated so the frame sizes cannot be adjusted to fit the dwarf walls. Instead the dwarf walls must be built to precisely the right size. Bricks are ideal but irregular natural stone may require carefully cropping.

AIR BRICKS IN DWARF WALLS: Air bricks can be built into the dwarf walls at regular intervals, which is an inexpensive way to provide low level ventilation. This will provide a healthy air flow through the greenhouse to ensure improved growing conditions and better crops.

THIS PREMIUM QUALITY GREENHOUSE: These high quality premium greenhouses are built to a specification which was originally developed for conservatories and not greenhouses. The heavy duty aluminium frame features box section aluminium glazing bars, corner posts and ridge beam. In addition, the base cills feature heavy duty box section beams. The basic prices include 4mm thick toughened safety glass as standard with 6mm twinwall polycarbonate available as an option. The glazing is retained neatly with a substantial rubber external gasket. The edges of the glass are completely concealed. The sophisticated glazing system is stronger and neater than other greenhouse glazing systems. Other standard features include free gutters with downpipes and stop ends.

CORNER PEGS: The cills include corner pegs which are designed to be buried in the ground or set in concrete. This is recommended in less sheltered locations. The pegs are used as angle brackets to fix the corners together but they also extend downwards into the ground. If your greenhouse is sited on an existing patio or paved area you can cut the pegs off at ground level.

POWDER COATED ALUMINIUM: The powder coated finish is more attractive than the stark silver finish aluminium greenhouses. The tough finish also has excellent weathering properties and retains its gloss and colour superbly. A good example of powder coating is the finish on your washing machine. Powder coated aluminium greenhouses have a similar finish.

CLIP FREE GLAZING SYSTEM: Unlike most greenhouses, the glazing system does not require any wire clips or bar capping strips. The glazing is retained neatly with a substantial rubber external gasket. This glazing system was originally developed for conservatory glazing. It is a sophisticated glazing system which is stronger and neater than other greenhouse glazing systems. The glazing panels are held in position along the entire length of the glazing bar. As a result, when the frame is fully assembled the glazing panels are more securely fixed and do not come out so easily.

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: Sizes are sometimes rounded to the nearest nominal size for ease of reading but the correct 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. All sizes are approximate.

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. Although size limits apply, toughened glass panes are longer than horticultural glass, with no overlapping glass and fewer joins. Where required, joins are neat in-line H-profile joins. All glass supplied is 4mm thick toughened safety glass.

TWIN WALL POLYCARBONATE: Twin wall polycarbonate is virtually unbreakable and very practical. With small children or pets around polycarbonate greenhouses are safer. Polycarbonate is also safer to handle during installation. Polycarbonate greenhouses provide a similar growing environment to glass greenhouses with better insulation properties and reduced glare. Polycarbonate also provides good insulation from frost and maintains a more even temperature for better plant growth. Twin wall polycarbonate also diffuses light to prevent scorching. Twin wall polycarbonate glazing is stronger than the flimsy single skin polycarbonate sheeting supplied with some greenhouses.

HEATERS: We offer a huge range of heaters so whatever your specific requirements we have a heater to do the job. Our electric heaters require a standard domestic 13 amp electricity supply. Our propane gas heaters require permanent trickle ventilation when in use. As an approximate guide, a 3kw heater will heat a greenhouse up to 8'x12' or provide frost protection only up to 10'x15' in normal site conditions. A 1.5kw heater will normally heat a greenhouse up to 6'x8' or provide frost protection only up to 6'x12'. Internal partitions are often used in large greenhouses to create a smaller warm room which is cheaper and easier to heat.

HEATING REQUIREMENTS: Heating requirements vary for several reasons. Location is one factor with more heating required in Scotland than in southern England and less heating required in a sheltered position. The design is also a factor. For example, dwarf walls improve the insulation and lean to greenhouses absorb warmth from the existing wall. Another factor is the materials used. Polycarbonate greenhouses retain heat better than glass and wooden greenhouses retain heat better than metal greenhouses. We recommend you to buy a bigger heater than you need - you can always turn it down.
