FREE SAME DAY INSTALLATION - THE BENEFITS: Our free in house installation service is not just convenient, it is also your assurance of a better quality greenhouse. This is because any building which includes free installation is invariably better made using quality components. Over time regular feedback from fitters ensures that design faults and weaknesses have been rectified. Same day installation is convenient for you and cost effective because it saves travelling costs. The fitters will deliver your greenhouse and then install it, all at the same time. Others send sub-contract fitters separately, often from far away and often a week or two after the delivery. Waiting for the fitter can be very frustrating. Sub-contract fitting is also much more expensive because of the travelling costs. The fitting service does not include base preparation. A flat and level base is required, which can be made using concrete, paving slabs, pressure treated timber or plastic. In many areas we offer a base laying service as an option. We also offer heavy duty plastic base kits in all areas.

SCANDINAVIAN REDWOOD OR WHITEWOOD: The most widely used timber in the UK for years, Scandinavian Redwood and Whitewood grow in the well managed forests of Scandinavia and the coldest parts of Northern Europe. The cold climate ensures slow growth. The growth rings are much closer together than faster growing trees from warmer climates. As a result the timber is heavy and durable with a close grain pattern. The wood is seasoned and kiln dried to achieve the correct moisture content before it is machined. Redwood and Whitewood are so similar in appearance and performance that it is difficult to tell the difference. Both are classified as slightly durable and treatment is required for outside use. The forests of Scandinavia and Northern Europe have been responsibly managed on a sustainable basis for centuries so Scandinavian Redwood or Whitewood is an enviromentally friendly choice.

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.

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. Greenhouse glass is subject to lower visual standards than other more expensive glass and may include blemishes or imperfections which do not adversely affect the performance.

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. 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. All sizes are approximate.

COLOURED PAINT FINISH: This greenhouse is available treated inside and outside with a high quality microporous paint system in a choice of opaque colours. Microporous woodstains are impervious to water but not to water vapour, which allows the wood to breathe. Microporous woodstains offer superior absorption and protection plus greater durability. The appearance of colours and shades may vary between different screens or devices. Although our opaque preservative finish largely obscures the surface of the wood, the grain and other natural features may still be discernible through variations in colour and texture.

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.

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.
