Our cold frames are designed to enhance the effectiveness of your glasshouse, providing an additional cold-protected environment and creating ideal conditions for hardening-off foliage propagated in the glasshouse. They can also be used for starting early salad crops and over-wintering delicate shrubs.
Constructed in robust aluminium sections, the cold frames are powder coated for a long and trouble-free life. Ventilation is made easy by an internal set of runners, giving you three opening positions. To operate you simply lift the handle and guide into the desired level.
Typically, the cold frames are 0.9m deep but can be built according to your space and growing needs. They can be attached to your greenhouse base, or can be freestanding in your garden. A ground plan showing all required dimensions and tolerances will be prepared by Alitex; this should be passed to your nominated builder for the preparation of the brickwork.*

Cold Frame Vent Slides
If vent slides form part of your order, these allow warmer air from within the greenhouse to transfer into the cold frames. The main purpose of the vent slide is to create ideal conditions within the cold frame to harden off tender greenhouse plants gradually, or alternatively to get a head start on some early spring crops.
The sliding vents are simply operated by sliding them open or closed as required by using the handle provided. The sliding vents are fitted to one side of the plinth wall only, typically the side within the cold frames.
