THIS POLYCARBONATE GREENHOUSE: These great value greenhouses include a number of unique features to improve the structural rigidity and the glazing. Standard features include vertical and horizontal PVCu bar capping with triple corner brackets and additional bracing to improve the strength. The aluminium frame is green powder coated as standard and the glazing is twinwall polycarbonate, which is often an expensive extra. These sensationally cheap greenhouses are always in stock and the price includes fast delivery. The precise manufacturing and careful packing is a match for our most expensive greenhouses. With such a competitive price this metal greenhouse is a popular choice with first time buyers. With the ultra safe polycarbonate glazing it is also a popular choice for the elderly and families with children or pets.

EXTRA RIGIDITY: This greenhouse weighs more than most other polycarbonate greenhouses. The strong frame features three eaves corner brackets instead of one like other greenhouses. This ensures a stronger connection between the front, the side and the roof. The design also includes the maximum possible number of eaves struts to further improve the strength and rigidity.

UNIQUE ALL ROUND PVC BAR CAPPING: The unique glazing design ensures that the polycarbonate panels are held in place better than most polycarbonate greenhouses. A few other greenhouses feature PVCu bar capping but normally this retains the glazing along the vertical edges only. The top and bottom edges receive little or no attention. This greenhouse includes additional horizontal bar capping which retains the glazing at the top and bottom edges aswell. Because the glazing panels are retained on all sides, when the frame is fully assembled the glazing panels are more securely fixed and do not come out so easily.

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.

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.

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.

TIPS IF HEIGHT IS RESTRICTED: At sites where the wall height is restricted it may be possible to excavate the base area in order to reduce the ground level. This is not always practical at every site as it depends on the surfaces. It may also be possible to partially bury the base plinth or cills in the ground. This is best done after the greenhouse has been delivered, so you can use the actual greenhouse components for reference. You can use the cill components to ensure that the door opening is unobstructed, also to ensure that you excavate in exactly the right area. It is normally possible to gain a couple of extra inches (50mm) in this way which effectively reduces the overall ridge height.

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. 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.

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.

GREENHOUSE ACCESSORIES - ALWAYS IN STOCK: As a specialist greenhouse supplier, established since 1981, we pride ourselves on supplying more options and accessories than other suppliers. All of our greenhouse accessories are always in stock all the time. Many accesories are only available when you buy the greenhouse and not available separately. However, we always make an exception for one of our customers - if you purchased your greenhouse from us we will always supply any accessory you need at any time, even many years afterwards.

BASE ANCHOR FIXING KITS - FOR SOIL OR CONCRETE: This kit makes it easy to fix your greenhouse down securely into concrete, paving slabs, decking or even soil. The brackets are profiled to grip the inside of the greenhouse base plinth with fixing holes on the inside. The brackets are fixed from inside the greenhouse with coach screws fixed down into the concrete, paving slabs or decking. If you want to site your greenhouse on soil you will need a concrete trench around the perimeter or smaller pockets of concrete into which the brackets can be fixed. You can fix the base plinth down with screws and wall plugs but it is much easier with our profiled brackets. Fixing the greenhouse down is recommended at all sites. The kit includes:

  • Profiled anchor brackets - shaped to grip the inside of the greenhouse base plinth, with predrilled fixing holes
  • Masonry drill bit - used to drill the correct size hole in concrete or paving slabs
  • Zinc plated coachscrews - supplied complete with washers and plugs to ensure a neat easy fit

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.

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.
