Buying a Wooden Greenhouse?

When deciding what type of greenhouse to buy, the materials used are an important factor. Aluminium framed greenhouses are very popular due to their availability and affordable cost. However, many people prefer the more traditional wooden greenhouse, which usually costs more. A wooden one is generally more attractive and the best ones on the market are resistant to rot and don't need much maintenance.

Cedar or red cedar wood is the timber frame of choice for many manufacturers. Another material used is the steel frame greenhouse. This is usually the least expensive of all but needs prevention treatment for rust. It all depends on what your priorities are. Some designs incorporate some aluminium framing to strengthen the structure.

This also gives the owner the option of dividing the greenhouse with glazed partitions in order to grow plants requiring different growing conditions, using a 'hot area' and a 'cool area'. Suppliers often fix the structure onto a brickwork base but it will fix onto concrete or flagstones. The timber frame can also be used for lean to and mini greenhouses.

The workbenches inside the greenhouse, sometimes called the greenhouse staging, are usually made from aluminium or wood. Cedar wood benches complement cedar wood framed greenhouses. They are conveniently erected at waist height and are in a tray design or slatted. The slatted tops are good for ventilation and help to prevent disease and encourage plants with stronger roots. The Alpine House is a traditional timber frame design with louvre vents across the sides and it is one of the best greenhouses for ventilation. Most owners do not heat this type and insulation is not necessary. The Alpine is only closed if winter temperatures drop too far.

Western Redcedar (correctly spelled as one word) is indigenous to the Pacific Northwest and is the preferred frame for many manufacturers because of its special qualities. This cedar contains natural oils resistant to wood boring insects and deterioration caused by moisture. It is a straight grain wood and doesn't warp and it also retains heat and insulates well, a combination ideal for wooden greenhouses resulting in warmer temperatures in the colder months and cooler temperatures in the hotter months. This wood is highly recommended for a long lasting greenhouse.

The wooden greenhouse particularly suits a traditional cottage garden and an older house. If kept clean and tidy, it will add to the value of the property and may be a good selling point. The frame is heavy enough to withstand strong winds, so it is practical and aesthetically pleasing. New materials may come and go but wood is here to stay!
