Description

The Elite Kensington 20ft long lean to greenhouse is the largest in the 4ft wide range, built from high quality aluminium that will not rust, warp or rot.

It's an exceptionally rigid frame, maintenance free, that you can personalise into a bespoke structure using Elite's exceptional list of optional accessories.

First of all, choose a colour for the frame. The alternatives start at milled aluminium and in addition there are several different coloured powder coatings, you certainly won't be limited to the usual green or silver.

Then you must decide on the number of entry points that are needed. Single doors can be installed at one or both gable ends, and further smooth sliding doors may be located at the front of the greenhouse. The latter can be double, so dramatically increasing accessibility. 

Summer heat can increase the temperature inside a greenhouse to heights that are detrimental to plants. So three roof vents and a louvre are already fitted. You can choose to install more vents to draw in cooling air and also to have automatic openers, so that when you are away from home temperature and humidity are kept at acceptable levels.

If the lean to is positioned so that you can access it straight from the house, you must install toughened glass. Otherwise you have the alternatives of horticultural or polycarbonate glazing. Bar capping, the same colour as the frame, can be fitted to improve the greenhouse's appearance and further secure the glazing.

With so much space to grow a large selection of plants, shelving and staging in addition to the standard aluminiul extruded shelf is essential. You'll find lots to choose from on the list of accessories, different widths and configurations that will be so useful in such a productive growing area.

The heavy duty durable gutter not only provides extra strength for the greenhouse, the rainwater that's collected can be channeled into a butt by the popular rainwater collection kit, ready to be recycled. Plants really do prefer it to tap water.

Finally, you must remember that a base is always required. This can be handbuilt with bricks or slabs but probably the best solution is to buy an Elite base that is specifically designed for the job and can be the same colour as the frame.

Please note that the photographs illustrate various Kensington greenhouses and show both standard features that are listed below and optional accessories that can be purchased separately.

Option 2 > Choose Your Greenhouse Glass

with 3mm Horticultural Glass

with 3mm Horticultural Glass

Horticultural 3mm float glass as traditionally used in greenhouses. This is the standard minimum specification and is INCLUDED with your frame choice. Provided in traditional panes which are supported using overlapping clips. This type of glass isn't recommended if you have children or pets around due to the more fragile nature.

with Single Sheet Toughened Glass

with Single Sheet Toughened Glass

Toughened to British Standard Class 6206 Grade A and European Standard EN12150 for maximum light and extra safety. All toughened glass models in this range utilise full sheet glass in the roof and side walls. This makes for a much cleaner line with no build up of moss or algae where the sheets of glass would normally overlap.
The thickness of the glass varies, the long roof and side panels are 4mm thick whilst the shapes and smaller rectangles are 3mm thick.
with 6mm Polycarbonate Glazing

with 6mm Polycarbonate Glazing

As well as the safety element it is a superb insulator, with the air trapped between the inner and outer skin acting as a mini double glazing unit. This will reduce winter heating costs. To aid growing polycarbonate defracts the sun's rays twice as it passes through the twinwall. This effect disperses the light far more evenly around the greenhouse. Supplied in a full sheet format and offers a more opaque appearance.

Option 3 > Do I Need a Base?
