WESTERN RED CEDAR: Western Red Cedar is a naturally resilient timber which lasts longer than pine and other softwoods, even if never treated from new. It has been widely used in construction for over a century. During this time cedar has deservedly earned an unrivalled reputation for its attractive appearance and extraordinary durability. It is the ideal choice for people who are too busy to maintain their garden building. This oily timber has a strong but pleasant aroma which repells insects. Cedar contains hardly any knots. If untreated it will fade to a silvery grey colour. Western Red Cedar is a sustainable resource from the well managed forests of North America.

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.

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.

BASE PLINTH: The base plinth makes installation much easier. It is designed to be a portable and prefabricated foundation beam. The plinth features a flat underside to spread the weight of the greenhouse over a larger area. The base plinth can be placed on any flat and level surface including soil, gravel, decking, concrete or paving slabs. It is best to prepare a perimeter footing of concrete or paving slabs for the base plinth to stand on. However, with care the base plinth can be placed on any surface including soil or gravel provided that the ground is flat and level.

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.

CEDAR CAPPING: The external capping protects the main structural framing timber which remains dry in all weather. Cedar capping provides a softer and more traditional appearance. The natural durability of cedar combined with the use of aluminium in vulnerable areas ensures that cedar capping will last. The cedar capping is treated with a colourless preservative.

ALUMINIUM CAPPING: With aluminium capping specified, there is hardly any external timber. The appearance is more modern but the overall impression remains of a beautiful cedar greenhouse. With the main structural timbers protected from the elements, the aluminium capping provides the ultimate performance with the look and feel of cedar and the durability of aluminium. The aluminium capping is powder coated grey.

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.

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.

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.

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.

ROLLER BLINDS: Shading is normally required on one side of the greenhouse only, the sunny side. Attractive and versatile, these fully retractable and tensioned roof roller blinds will protect your plants. Internal blinds also provide significant insulation and reduce winter heating costs. Each blind provides shade for one glazing section. Roller blinds are normally fitted to one side of the roof. This protects against the strongest sunlight from directly overhead. If extra shading is required the blinds can be fitted just as easily in the walls of the greenhouse. The length of a blind can be reduced easily if required to allow for protruding vents handles. All fittings are supplied. DIY installation requires only a spanner.

ECO-PAVING FOOTPATH: A durable eco-paving footpath is inexpensive and easy to install inside any greenhouse. The footpath is normally laid inside the greenhouse after the assembly is completed. The kit sometimes fits comfortably inside the greenhouse with a few inches to spare. Sometimes it is overlength but it can be cut to fit. Our durable eco-paving footpath is a practical and affordable alternative to slabs or concrete. Lightweight and easy to install, these recycled polypropylene pavers simply click together. The interlocking design ensures greater rigidity and spreads the weight. Our eco-pavers are self draining and fully relocatable, unlike paving or concrete. Our eco-paving is less brittle than concrete paving slabs, with a strong supporting structure. The surface looks and feels similar to pressed concrete slabs, with a slightly textured finish. Designed to spread weight, the finished floor or footpath is self draining and suitable for wheelbarrows. Each eco-paver is 385mm x 385mm and 40mm thick. Weed control membrane is included. Laying eco-paving directly on soil is not recommended. Eco-pavers can be laid on a layer of gravel or pea shingle if it is carefully compacted and levelled. Each paver should be fully supported.

RECYCLED PLASTIC BASE KITS: Our durable eco-grid and eco-paving base kits are a practical and affordable alternative to slabs or concrete. Lightweight and easy to install within a few minutes, these 100% recycled polypropylene pavers simply click together with no fixings needed. The interlocking design ensures greater rigidity. Designed to spread weight, our plastic bases are self draining and fully relocatable, unlike paving or concrete. A fully paved base has no soil inside the greenhouse. Alternatively, a perimeter base features a single row of pavers laid around the perimeter of the greenhouse with soil inside. You can also add a footpath in the centre of a perimeter base. The base is normally at least 2" or 50mm larger than your building. Where space permits the base is normally laid full size but if required in a tight location our plastic pavers can be cut. Fast delivery within 3-5 days ensures that you can start work quickly.

ECO-GRID BASE KITS: Eco-grids are recommended if the sub-base is soil, sand or pea shingle but not on hard surfaces such as concrete, because the underside is not flat. Integral pegs on the underside help to level the base grids more easily in soil or sand or shingle. Our eco-grid plastic bases can support up to 200 tonnes per square metre. We offer exactly the same eco-grids as driveways and carparks. Each eco-grid is 472mm x 472mm and 40mm thick with an immensely strong 60x60mm hexagonal cell structure. The kits include weed control membrane which is laid below the pavers. Extensive preparation is not normally required. First the ground is levelled and then the membrane is laid directly on the soil. The pavers are laid on the membrane or on a thin layer of sand or pea shingle. The pavers should be backfilled with gravel or pea shingle which is not supplied. Approximately 15-20kg of shingle is required per paver. We recommend checking this with your supplier or, if you can, buy less gravel than you need to start with.

ECO-PAVING BASE KITS: Eco-paving is recommended if the sub-base is a hard surface such as concrete or paving slabs, because the pavers feature a flat and level underside. Our eco-paving is less brittle than concrete paving slabs, with a strong supporting structure. The surface looks and feels similar to pressed concrete slabs, with a slightly textured finish. Each eco-paver is 385mm x 385mm and 40mm thick. The pavers are quickly and easily laid over an existing hard surface. Eco-pavers can be used to build a perimeter base but care is required to provide a solid sub-base. Ideally the sub-base should be concrete or a similar hard surface. Laying eco-paving directly on soil is not recommended. Eco-pavers can be laid on a layer of gravel or pea shingle if it is carefully compacted and levelled. The kits include weed control membrane which can be laid below the pavers. Each paver should be fully supported.
