TOPWET is a traditional and one of the leading European manufacturers of roof elements for the drainage of flat roofs, terraces, and balconies. The company's products always feature an integrated sleeve of waterproofing membrane made from materials such as BIT, TPO, EPDM, and PVC, sourced from the most common waterproofing manufacturers. The advantage of the integrated sleeve is the speed of installation and the guarantee of a watertight connection to the drain body. The product body is made from a tough plastic that offers excellent mechanical and thermal properties, along with a long life time expectancy. The double-walled design eliminates thermal bridging and reduces the risk of condensation.

The product range also includes unique heated versions of the drains with an integrated self-regulating cable, offering reliable drainage even in winter, which has no equivalent on the market. The product dimensions range from 3" to 6". The two-stage drains with systematic connection to the vapor barrier provide a key competitive advantage. With a wide range of retrofit drains, roof repairs couldn't be easier. A green roof shaft is used to drain vegetation roofs, allowing the entire system to be periodically cleaned. Drainage through the attic is complemented by a series of through-wall parapet drains and safety overflows. 

All of this is offered at a competitive price!
