Reinforcing the greenhouse makes perfect sense, especially in stormy regions, and offers additional security for its statics. Simple improvements to prefabricated houses can be easily carried out using the right material and significantly increase the stability of the building.
How to strengthen a greenhouse?
To strengthen a greenhouse, you should install diagonal braces on frames, doors and windows, fix windows with silicone, secure external walls with earth spikes and metal cables, and replace screws and nuts with quality steel.
Especially at the end of the gardening season, hardware stores and garden centers once again offer unbeatably cheap offers to get their remaining stocks out of storage. Bargain prices between 500 and 1,000 euros for a medium-sized greenhouse are not uncommon. Unfortunately, after construction, many of these top offers turn out to beextremely lightweight buildings, so repairs are advisable So: strengthen the greenhouse, primarily in places that have to do with the statics of the structure have.
Cracking point: rickety frames
The wall and window frames, which are usually pre-assembled, often leave a lot to be desired in terms of stability, bend easily and are hardly torsion-resistant in storms and rain. The frames should therefore definitely be reinforcedcross corners by installing stable diagonal struts. The best way to do this is to use aluminum profiles (€22.00 on Amazon), which are only screwed on from the outside and are available cheaply in any hardware store.
Reinforce doors and windows on the greenhouse
Polycarbonate multi-wall panels are usually used for the windows, which a slightly stronger wind tends to push out of the locking grooves later. With a little silicone or putty, these parts can be very easily stabilized, then sit firmly in the guide and ensure proper insulation in the interior of the greenhouse.
Additional security of the external walls
Although most prefabricated houses include a closed floor frame as an accessory in the package, which simply needs to be screwed onto the existing foundation: If possible, anchor the walls at all corner points withearth spikes and stable metal ropes in the ground. This gives you greater security that your greenhouse will still be in the same place after the first autumn storms. The tension of the ropes should also be readjusted regularly.
Savings on screws and nuts
Which is not necessarily related to their number and size, but rather to the quality of the material of these important connecting elements. They often cannot be removed later, tear out or have rounded heads. It is best to replace the most important screws and nuts for all load-bearing elements as a prophylactic with onesmade of dimensionally stable quality steel.
Tip
In addition to reinforcing the greenhouse, it also makes sense if there is a hedge in the immediate vicinity that lets the wind through but weakens it very much. A tight fence has the opposite effect and actually increases the suction effect considerably during a storm.
