THIS PREMIUM QUALITY GREENHOUSE: These well engineered aluminium greenhouses feature black powder coated frames with toughened safety glass at surprisingly affordable prices. These greenhouses are always in stock and the price includes free next day delivery. From a technical viewpoint this greenhouse is heavier and more rigid than others at similar prices and the glazing is held in better. The precise manufacturing and careful packing is a match for our most expensive greenhouses. Sophisticated features include box section framing throughout with smart and strong aluminium bar capping. The competitive price and fast delivery ensure that this greenhouse is an ever popular choice.

EXTRA RIGIDITY: This greenhouse is heavier than most other greenhouses with box section framing throughout. Box section frame profiles feature a hollow chamber for additional strength. It is not just the ridge and eaves which are box section but also the corner posts, cills and glazing bars. Even the door and vent framing are box section profiles. The strength of the eaves and ridge is significantly improved by simple push fit corner connectors. In addition, specially designed corner brackets ensure that the vent frame and door framing are stronger.

ALUMINIUM BAR CAPPING: The decorative aluminium glazing beads are more attractive than other greenhouses but they also retain the glazing better. The unique glazing design ensures that the glass is securely fixed in place continuously along every edge including the top and bottom edges. With most greenhouses the glazing is retained along the vertical edges only and the top and bottom edges receive little or no attention. The glass is retained along the entire length of the framing. As a result, when the frame is fully assembled the glass is more securely fixed. The unique aluminium beads clip into a groove in the aluminium glazing bars. The tight fit ensures that the glass/glazing is retained without fixings but the real strength comes from discreet self tapping screws which are fitted on the inside. The holes are predrilled so this important task is quickly and easily completed. The screws are partially concealed within a groove in the framing. The result is the strongest and neatest greenhouse glazing system we have ever seen in any greenhouse.

STRONGER GABLE WALL GLAZING: The tallest glazing panels are divided in two for added strength. One piece panels are more likely to flex and spring out in winds. Strong aluminium glazing bars at the horizontal joints provide additional rigidity, unlike the plastic jointing profiles used by some others. The grooves in the horizontal glazing bars ensure that the glazing is retained more securely.

UNRIVALLED BRACING: The kit includes optional horizontal braces, diagonal braces, eaves struts and ridge struts. The braces and struts are recommended at exposed sites. At less exposed sites the braces and struts are not essential if you prefer an uncluttered design. All of the braces and struts can be easily fitted or removed retrospectively if you change your mind.

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.

STRUCTURAL CILLS: This greenhouse includes low profile structural cills. A separate base plinth is not required. Structural cills are designed to suit a low threshold doorway. They are stronger than normal greenhouse cills with a lower profile than a traditional base plinth. Structural cills feature a flat underside to spread the weight of the greenhouse over a larger area. They can be placed on concrete, paving slabs, bricks or decking but structural cills should not be placed on soil or gravel.

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.

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.

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.

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 supply exactly the same eco-grids for use in 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 KITS - BASES, FLOORS AND FOOTPATHS: This durable floor kit is a practical and affordable alternative to slabs or concrete. Easy to install within a few minutes, these recycled polypropylene pavers simply click together with no fixings needed. The pavers are easily prised apart so the floor is even quicker to remove if required. 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. 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. 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.

The Eco-paving internal floor sometimes fits comfortably inside the greenhouse with a few inches to spare. Sometimes it is overlength but it can be cut to fit. The finished floor is self draining and suitable for wheelbarrows and wheelchairs. 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.

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. Designed to spread weight, the finished floor or footpath is self draining and suitable for wheelbarrows. 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.

WPC COMPOSITE DECKING KITS: This superb quality WPC wood plastic composite decking closely resembles real wood, with the same look and feel. However, it is virtually maintenance free and it will never rot. At a glance it is difficult to tell the difference between this composite material and real timber decking with a stained finish. Furthermore, the similarities are not skin deep like a thin veneer. The realistic finish has a fibrous surface which looks similar to the grain of real wood. This synthetic composite is also heavier and stronger than real wood. The strength, durability and lack of maintenance make this superb decking a popular choice with pensioners and discerning commercial buyers such as care homes. Occasional cleaning with soapy water normally restores the original appearance. If any dirt or stains become ingrained after prolonged neglect even the most stubborn marks can be cleaned with a pressure washer.

Our WPC composite decking is a revolutionary material which provides all the benefits of real wood without the maintenance. It can be left outside uncovered all year round. Unlike real wood this synthetic wood is a weatherproof material with no knots, splinters, machining marks or other imperfections. It will never develop splits or shakes and no sap will ever ooze out of it. Our wood plastic composite is an equal mixture of real wood and recycled plastic. Even the wood is a mixture of sawdust and unusable offcuts, so it is the ultimate environmentally friendly alternative to wood. The colour pigments are mixed in before the powdered composite is moulded into shape, so the colour runs all the way through the finished product. The boards are completely impervious to water. The boards can be sawn, drilled and screwed, just like real wood. You can fix it with standard woodscrews. Being heavier and denser than real wood, screw fixings are actually stronger in composite boards.
