Strong and stable, the 8ft x 4ft Classic Cold Frame provides plenty of space to protect your plants. The strong aluminium framework comes with a 25 year guarantee, and is glazed with 3mm toughened safety glass for durability. Cold frames have a wide variety of uses, including bringing on early vegetables, hardening off growing plants, and providing protection for plants such as alpines. They have a number of unique benefits, including a versatile frame that can be easily moved from place to place once the glass has been removed; and flexible side and roof panels that allow easy access and ventilation. These panels can be removed to allow in rain and let taller plants to grow through the roof. Cold frames are built to withstand rough weather conditions, including heavy wind and snow. This model is designed to stand directly on the soil or a raised base, and can be fitted with our 8ft x 4ft Wooden Raised Base.
