The Bio-Top combines multifunctional design and premium quality
A true classic among freestanding glasshouses, the Bio-Top combines timeless design with outstanding quality. Its appeal lies in its high-quality design and the flexibility to customize it with a range of carefully selected details. Whether you are planning ambitious gardening projects or creating an additional garden room to enjoy comfortably even in the colder season, the Bio-Top offers exceptional versatility. Thanks to its wide range of size options, it is also perfectly suited to smaller gardens – without compromising on luxurious features. The Bio-Top is constructed from specially engineered, ultra-stable, torsion-resistant aluminium profiles. They not only provide outstanding load-bearing capacity but also eliminate the need for crossbars, creating the clean, unmistakable look that defines the Bio-Top. Double glazing with insulated safety glass further enhances the Bio-Top’s excellent stability and thermal performance. With the Bio-Top, you are investing in a greenhouse that combines exceptional quality with refined design – one you will continue to enjoy for many years to come.
