THIS ROBINSONS GREENHOUSE: These high quality Robinsons greenhouses are not only stronger than basic greenhouses but also taller and more comfortable with easy access and ample ventilation. This Robinsons greenhouse includes toughened safety glass throughout, large pane glazing, extra eaves height and lockable doors with low thresholds for easy access. The box section aluminium frame provides additional strength and rigidity. Other standard Robinsons features include free gutters with downpipes and stop ends and PVC bar capping to provide an attractive finish. The sophisticated design features concealed fixings and weatherproof doors and roof vents. Options include ornate ridge crests and attractive built in aluminium staging and shelving.

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.

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 to BS6206 Class A.

BAR CAPPING: Greenhouses with a silver finish include white PVC bar capping. Colour painted finishes come with aluminium bar capping. Traditionally greenhouse glass is secured in aluminium greenhouses using stainless steel or galvanised glazing clips. Bar capping is an effective alternative which is at least as strong as clips but neater and easier to clean. The standard glazing clips are replaced with full length strips which hold the glass along its entire length. Bar capping cannot be fitted in a greenhouse with overlapping glass. This quality feature is only available with large pane glazing. Bar capping is coloured to match the greenhouse frames.

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.

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.

SILVER FINISH ALUMINIUM: Silver finish is the natural colour of aluminium before it is painted. It is cheaper than painted aluminum but just as strong and durable. An unpainted aluminium greenhouse will gradually oxidise producing fine grey powder forms on the surface of the greenhouse. This is the aluminium's natural self protection and it does not harm the greenhouse. Oxidisation occurs quicker in areas of high pollution or in coastal areas.

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.

BUILT IN ALUMINIUM STAGING: Our built in aluminium staging provides a useful work surface and additional growing space in your greenhouse. It is bolted to the greenhouse frame and adjustable to any height. There are no legs below the staging, which gives you more flexible storage space. The staging is made to the same lengths as the internal walls to ensure a neat fit when a full length staging is specified. For this reason the actual length of the staging may be slightly less than the nominal lengths listed. If the staging is fitted to one side only this leaves the other side free for growing taller plants such as tomatoes. The staging can also be fitted to both sides to maximize the growing area for shorter plants.

BUILT IN SLATTED SHELVING: The built in slatted shelving matches the staging although it is not as wide. It is fixed to the greenhouse frames and provides extra growing space or useful extra storage. The shelving is adjustable to any height but it is often fitted at a higher level than the staging. Often the shelving is fitted above the staging where it provides handy storage at your fingertips directly above the main growing area. The shelving can also be fitted at waist height for use as narrow staging on one or both sides. The shelving is made to the same lengths as the internal walls to ensure a neat fit when a full length shelving is specified. For this reason the actual length of the shelving may be slightly less than the nominal lengths listed.

VENTILATION: Improved ventilation increases the air circulation through the greenhouse for better growing results. Automatic openers react to heat which ensures that in hot weather the vents open in your absence and then close again when its cooler. Louvred ventilators provide a healthy air flow through the greenhouse to ensure improved growing conditions and better crops. Vents are an integral part of the greenhouse so it is easier to fit extra vents at the outset. Some plants such as alpines require more ventilation than others. If you are not yet sure which plants you are likely to grow improved ventilation will give you more versatility.

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.
