The 8x4 Access Aluminium Large Coldframe is a great way to extend the growing season and protect your plants from harsh weather conditions. Perfect for use all year round, the Cold Frame can be placed directly onto the soil or on a raised base, providing shelter from strong winds and harsh weather conditions. In the spring, when temperatures start to rise, the Cold Frame can also be used to house tender young plants, acting as an intermediary stage between the warm conditions of a greenhouse and the cooler environment of a garden.

This Large Access 8x4 Coldframe is made from aluminium, with a 25 year framework guarantee. It is glazed with 3mm toughened safety glass, and has sliding side and top panels for easy access. A full range of options are available below including Shelving, Louvre and Misting Kit.
