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 or decking. In many areas we offer a base laying service as an option.

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.

THERMALLY MODIFIED TIMBER: Thermally modified timber is a beautiful natural material with a projected service life of 30 years or longer. Only heat and steam are used in the treatment process and no chemicals are added. It is a lifetime preservative treatment. The timber is gradually heated to a high temperature which permanently changes the physical properties of the wood. The resistance to decay and stability of the wood are significantly improved as are the insulation properties. The moisture content is reduced and resin is removed so it cannot seep out of the wood. The process was developed in Finland but it is based on ancient knowledge. For example, the Vikings knew that fencing poles with a burnt surface were more durable. The finished colour of the wood is an attractive brown which can be painted or stained just like any other wood. If the wood is left untreated it will fade over time to a silver grey colour in the same way as other timber.

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 - DEPTH 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 depth and the second dimension is the width. The depth refers to the overall depth including the front projection. The width refers to the front and rear walls including the door wall. The sizes listed are the external wall sizes. All sizes are approximate.

THERMALLY MODIFIED TIMBER PANELLING: The greenhouse frames are fitted on a 20mm thick black PVC damp proof barrier. The integral timber panelling features 12mm thick tongued and grooved matchboarding (finished size after machining). All timber is thermally modified, a lifetime preservative treatment. Timber panelling offers better heat retention in the winter than fully glazed greenhouses and it is ideal for growing shade-loving plants such as ferns. The cladding boards are fully built into the greenhouse frame as an integral part which cannot be detached.

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.

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.
