With the 100 base, our cold frame is perfect for tortoises, guinea pigs and other small animals. The substructure measures 1.03 x 0.91 x 0.26 m (W x D x H) and the construction is adapted to the cold frame 100. The glazing consists of 6 mm ISO twin-wall sheets made of highly break-resistant polycarbonate with “longlife” UV protection on the outside. The turtle base is easy to assemble, convenient to install and, thanks to the lockable swing flap measuring 23.5 x 25 cm (H x W), always gives your pets perfect access to the fresh air outside.
