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.
HORTICULTURAL GLASS: Horticultural glass is the traditional glass for greenhouse glazing and it remains a cost effective option. Although brittle, glass is also rigid and it strengthens the aluminium frame. Glass is also heavy which helps to resist wind. Unless it is broken glass will not deteriorate unlike plastic alternatives which are easily scratched. Although polycarbonate is stable, styrene and perspex quickly lose their transparency. Horticultural glass is normally supplied in small panes up to 24" x 24". Because of this size limitation the glass panes are overlapped. Horticultural glass also features more minor blemishes and imperfections than other more expensive glass but the affordable price makes it a sensible option for any greenhouse.
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. Polycarbonate glazing is not recommended at exposed sites. Plants need plenty of water so your greenhouse should be close to a water supply and the site should be well drained.

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.
BASE ANCHORS - CORNER PEGS: The base plinth includes corner pegs which are designed to be buried in the ground or set in concrete. This is recommended in less sheltered locations. The pegs are used as angle brackets to fix the corners of the base plinth together but they also extend downwards into the ground. If your greenhouse is sited on an existing patio or paved area you can cut the pegs off at ground level. The offcuts can be used to as brackets to help secure the base plinth into the concrete.
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.
TWIN WALL POLYCARBONATE: Twin wall polycarbonate is virtually unbreakable and very practical. With small children or pets around polycarbonate greenhouses are safer. Polycarbonate is also safer to handle during installation. Polycarbonate greenhouses provide a similar growing environment to glass greenhouses with better insulation properties and reduced glare. Polycarbonate also provides good insulation from frost and maintains a more even temperature for better plant growth. Twin wall polycarbonate also diffuses light to prevent scorching. Twin wall polycarbonate glazing is stronger than the flimsy single skin polycarbonate sheeting supplied with some greenhouses.
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. 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.
INTERNAL SHADE NETTING: Shade netting is normally required on one side of the greenhouse only, the sunny side. Internal shading is supplied to approximately the same length as the greenhouse with a standard drop. Easily fitted or removed within a few minutes, the shading can be stored away when not in use. The shade netting does not interfere with the operation of roof vents. The specialist UV stabilised netting provides 70% shading. Internal shade netting keeps the heat out and stops delicate plants and seedlings from scorching. Each shading kit is supplied complete with fittings.
RECYCLED PLASTIC BASE KITS: Our durable eco-grid and eco-paving base kits are an 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. Designed to spread weight, our plastic bases are self draining and fully relocatable. A fully paved base has no soil inside the greenhouse. A perimeter base features a single row of pavers laid around the perimeter of the greenhouse with soil inside. The kits include weed control membrane which is laid below the pavers. First the ground is levelled and then the membrane is laid directly on the soil. The pavers are laid on the membrane. The pavers should be backfilled with pea shingle which is not supplied. Approximately 20kg of shingle is required per paver. Where space permits the base is normally laid full size but if required in a tight location the pavers can be cut to size with no loss of structural integrity. The base is normally a few inches larger than your building. Fast delivery within 3-5 days ensures that you can start work quickly.
ECO-GRID BASE KITS: Our eco-grid plastic bases can support up to 150 tonnes per square metre. Each eco-grid paver is 472mm x 472mm and 40mm thick with an immensely strong 60mm hexagonal cell structure. Eco-grids can be laid on soil or shingle. Integral pegs on the underside help to level the base grids more easily. If the sub-base is concrete or a similar hard surface we recommend our eco-paving which features a flat underside.
ECO-PAVING BASE KITS: Our eco-paving is stronger, less brittle and more difficult to damage than concrete paving slabs. The pavers have a strong grid structure underneath and the surface looks similar to concrete slabs. We recommend eco-paving bases for larger sheds and workshops, log cabins, commercial use and any other heavy duty applications. It is also recommended if the sub-base is concrete or a similar hard surface, because the pavers feature a flat and level underside. Eco-paving can also be laid on soil or shingle. Supporting up to 200 tonnes per square metre, each eco-grid paver is 385mm x 385mm and 40mm thick.
POLYPROPYLENE FLOOR TILES: A durable polypropylene floor or footpath is an affordable alternative to slabs or concrete. Easy to install within a few minutes, these interlocking polypropylene pavers simply click together with no fixings needed. Unlike slabs or concrete these pavers are lightweight, easy to install and fully relocatable. Designed to spread weight, the finished floor is capable of supporting 36 tonnes per square metre. First the ground is levelled and then the pavers are laid directly on the soil. The pavers can also be laid on grass, sand or gravel. The finished floor or footpath is self draining and suitable for wheelbarrows and wheelchairs. It fits comfortably inside the greenhouse with a few inches to spare. The tiles are easily prised apart by folding so the floor is even quicker to remove if required.
