Exaco BioStar

The BioStar 1500 uses a temperature-sensitive, wax-filled cylinder that expands as the air inside warms up. This expansion pushes the lid open automatically, requiring no electricity or manual adjustments to maintain a consistent climate for your plants.

Yes, the three lid sections are independent and can be opened manually at any time. This allows you to easily tend to specific areas of the cold frame without disturbing the temperature regulation in the other sections.

Yes, the frame is designed with specialized internal channels that redirect moisture away from the plants. This prevents water from pooling on the polycarbonate panels and dripping onto your foliage, which helps reduce the risk of fungal diseases.

The 8mm twin-wall polycarbonate is quite robust and provides excellent thermal insulation, making it well-suited for overwintering perennials and extending your growing season. However, it is not designed to support heavy snow loads, so you should clear off any significant accumulation.

Assembly is required and typically takes about an hour or two. The kit comes with all necessary hardware, but you will need basic tools like a screwdriver and a wrench to secure the aluminum frame and polycarbonate panels.

No, the panels are UV-stabilized to resist degradation and yellowing from sun exposure. This ensures the material maintains its clarity and structural integrity throughout many seasons of use.
