Introduction
Safety
Precautions when assembling a greenhouse:
The wearing of protective gloves and stout footwear is essential when handling glass and recommended even for
Polycarbonate which does not shatter but has sharp edges.
Protective goggles are recommended whilst handling glass and the glazing spring clips.
Assembly of the greenhouse frame is much easier with two people and essential for glazing with glass.
Site selection:
Choose a site in maximum light, ideally with no direct shade.
Avoid overhanging trees as much as possible as leaves will make regular cleaning necessary and broken branches are a
potential hazard.
Small trees, bushes or fences nearby can be helpful, acting as a wind break.
A position close to the house will make access easier for watering and tending and also make it easier to supply
power cables or automatic watering systems if required.
Site selection & preparation:
The site must be prepared so that the base of the greenhouse is level all round and checking with a spirit level is
required.
Base options & construction:
The use of purpose-made, galvanised steel bases is recommended.
They are made to fit the greenhouses.
It is easier to maintain a level and square foundation.
They are easy to install, requiring little expertise: full instructions are included in the pack.
Bases can also be constructed from bricks, blocks, or mounted on a concrete pad.
The bricks or blocks should be cemented onto firm and level concrete footings and the greenhouse frame drilled and
screwed to the base. Fig3.
If a concrete pad is made, it is important that this slopes towards the edges to prevent water ingress.
Time must be allowed for any concrete or cement to dry before mounting the greenhouse.
The base must be square or the greenhouse will be distorted. Fig1 & Fig2.
The greenhouse must be firmly fixed to the ground: the base should be constructed and installed before the
greenhouse assembly is undertaken.
