THIS PREMIUM QUALITY GREENHOUSE: These high quality greenhouses are not only stronger than basic greenhouses but also taller and more comfortable with easy access and ample ventilation. Quality features include toughened safety glass throughout, large pane glazing, extra eaves height and lockable doors with low thresholds for easy access. Other standard 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. We are currently offering extra ventilation as standard with a generous allocation of free louvre vents and free roof vents with free automatic vent openers, all included in the basic price. The number of free vents varies according to the greenhouse size.

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.

PVC BAR CAPPING: Traditionally greenhouse glass is secured in aluminium greenhouses using stainless steel or galvanised glazing clips. PVC 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 PVC strips which hold the glass along its entire length. PVC bar capping cannot be fitted in a greenhouse with overlapping glass. This quality feature is only available with large pane glazing. PVC capping is coloured to match the greenhouse frames.

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.

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. The best position for a lean to greenhouse is against a south facing wall and 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.

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 sloping walls to each side. The length refers to the front wall. The sizes listed are the external wall sizes. These sizes do not include the roof overhang. Many other suppliers quote the overall roof size which is much larger.

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.

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. 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.

BUBBLE INSULATION: Bubble insulation helps to protect plants and reduces winter heating costs. The insulation is attached to the inside of the frame using retaining brackets. The brackets are easily fixed to the greenhouse frame and they hold the insulation securely in place. This product is quick and easy to fit the first time and even quicker subsequently. The pack includes insulation, retaining brackets and instructions.
