Lean to greenhouses are also used as sunrooms and can simply become additional living space when attached to the house. A very warm and sunny bit of living space for you as well as your plants !

Halls Silverline Curved Eaves Lean to

This is a slightly unusual, but non the less attractive greenhouse from Halls. The eaves section at the front of the greenhouse is nicely curved. This is done by using clear acyrlic glazing rather than glass as it’s tough, flexible and UV resistant so it won’t discolour over time. The Silverline Lean-to is available as a 6×8, a 6×10 and a 6ft x 12ft model in silver or green powder coated finishes.

Greenhouse Safety Considerations

One important point to remember is that it’s generally accepted that if you are entering the lean-to from your house rather than from outside you should use toughened safety glass to ensure the very best safe conditions for your family when entering the greenhouse from the house.

Which greenhouse: Glass or polycarbonate?

Glass or Polycarbonate ?

One of the most frequent questions asked by greenhouse buyers who are new to greenhouses is “What’s best glass or polycarbonate?”. Traditionally greenhouses have always been glazed in glass both in the UK and abroad. In Germany for instance they have used frosted glass as it has the added feature of difusing UV rays !
However times are changing and so is the way we glaze our greenhouses. On the continent it has been common to use polycarbonate instead of glass and increasingly that is becoming the case here in the UK.

Polycarbonate Glazing for Greenhouses

The main advantage of polycarbonate over glass is its durability and strength and hence its safety benefits. Most greenhouses are glazed in 3mm horticultural glass which can be dangerous if broken as it breaks down into large shards which are extremely sharp. It is generally recommended that if the greenhouse is sited in a public place (allotment) or certainly where children or elderly people may be present that Toughened Safety Glass (to BS6206) or polycarbonate be used. Whilst toughened safety glass can still smash it breaks down into small pebbles like car windscreens or telephone box glass which is less dangerous that the shards of sharp glass with 3mm horticultural glass. Find a full range of leading brand toughened glass greenhouses at Greenhouse Stores.

Polycarbonate glazing is highly recommended if you have children or animals running around your garden as any impact will merely result in the child or dog/cat bouncing of the polycarbonate panel or at the worst popping a panel out which can be put back in place simply and quickly. A collision of this type with a glass greenhouse or coldframe would result in serious injuries.

Glass versus Polycarbonate

Polycarbonate greenhouses are also ideal for allotments and many local authorities now insist that allotment tenants use polygarbonate greenhouses rather than glass as part of their health and safety policy. Unfortunately greenhouses in gardens and allotments can also fall victim to vandalism and this is where polycarbonate has a very clear advantage over glass in that the cost of replacement polycarbonate is far cheaper and easier to source than glass. Generally speaking polycarbonate doesn’t smash so whether the wind has blown out a panel or a local vandal has knocked out a panel then it can simply be put back in and be secured with clips or glazing strips.
The insulation properties of polycarbonate are excellent. The most popular form of polycarbonate and by far the most effective greenhouse polycarbonate is 4mm twin wall polycarbonate sheet. This polycarbonate has a thermal insulation “R value” of around 1.42 whereas horticultural glass has an “R value” of around 0.93.
4mm twin wall polycarbonate also out performs glass where protection of your plants from harmful scorching UV is concerned also as it effectively diffuses light coming into the greenhouse whilst maintaining 80 to 85 % light transmission.
Polycarbonate greenhouses are becoming cheaper to buy with the advent of the “grow your own”  trend and it’s possible to get yourself set up with a polycarbonate greenhouse from around £200. All major greenhouse manufacturers now offer polycarbonate glazing as an option on their greenhouses and some manufacturers such as Gardman and Palram specialize in polycarbonate greenhouses.

Toughened Glass Greenhouse

A toughened glass greenhouse is the perfect choice for many greenhouse gardeners that live in temperate climates like the UK where the greenhouse may be exposed to high winds. Because toughened glass is supplied in one sheet (long pane) that goes from floor to eaves it is nice and heavy, it’s also generally thicker than normal greenhouse glass at 4mm. The extra weight in toughened glass gives your greenhouse much greater resistance to high winds and will stop your greenhouse frame from moving and twisting as the heavy glass keeps each section “square” under wind loads. Of course the biggest advantage of glass over polycarbonate is that you can see inside the greenhouse from the outside, therefore you can be looking down your garden from inside your house and still gaze lovingly at your tomatoes ripening !

Aluminium Greenhouse

Aluminium Greenhouse

The modern greenhouse comes in a few different configurations. Different frame materials are available, as are differing styles and sizes of greenhouse. Of course largely people are driven by the amount of space available to site a greenhouse or with a particular use in mind. Weather conditions in your location can also play a part in the kind of greenhouse you go for.
The most practical choice of frame by far are aluminium greenhouse frames. Aluminium is popular for many reasons. Chiefly, that it is entirely unaffected by adverse weather like rain and snow in as far as that it will not rot and need yearly maintenance like a wooden greenhouse. Aluminium frames can also be anodised. Anodising is a process the aluminium goes through to keep it looking pristine throughout its life. In other words it stays looking shiny and silver rather than going a dull grey colour as many aluminium greenhouses do and it will also never rust. Anodised frames are standard on some brands such as Vitavia greenhouses (see below).

Vitavia Orion 5000 Greenhouse 8×6 Silver

Many greenhouses today are available in a range of colours through the application of a powder coated factory finish. Green greenhouses seem to be the most popular colour for garden greenhouses as any train ride through suburban Britain will confirm ! Some greenhouse manufacturers offer a wide choice of colours such as white, brown and black on their powder coated frames. One such manufacturer is Elite Greenhouses who offer a choice of 5 colour options at an extra cost on all of their greenhouses from the smallest lean-to to the 12ft wide and up to 40ft long Elite Classique.

Elite High Eave Greenhouse 8×6 Silver

Though aluminium is a light weight metal it is extremely strong and hence it is suitable for carrying all available glazing options such as horticultural glass, toughened safety glass and polycarbonate glazing. Of course the major advantage of aluminium greenhouses over wood or steel is the total lack of maintenance needed  as they don’t rust and will never need painting.

Aluminium’s light weight also means that they are now shipped flat packed which means they are easier to transport and much easier to erect than steel or wooden greenhouses. Aluminium greenhouses popularity also means that the prices for these greenhouses are very reasonable indeed. There are many entry level greenhouses today at the sub £300 price level that are ideal allotment greenhouses featuring twin wall polycarbonate glazing and powder coated frame and steel bases. A very popular range are the Gardman green greenhouses in sizes 6×4, 6×6 and 8×6.

Aluminium Greenhouse Manufacturers

There are some very well known brands manufacturing aluminium greenhouses for the UK market today. Perhaps the best known is Halls Greenhouses who have been making aluminium framed greenhouses since 1936 here in the UK.
