Roof inlet gravity vent DN75 horizontal with insulated body, with PVC collar for PVC foil waterproofing only, with leaf basket and mounting protection HL64P/7

Roof inlet gravity – effective roof drainage

This roof inlet, made of high-quality PVC, is a key element of the roof drainage system. Designed for gravity water drainage, it works well both in new installations and during the modernization of existing ones. The construction with an insulated body minimizes the risk of thermal bridges, which translates into better building insulation.

A distinguishing feature of this model is a dedicated PVC collar, ensuring a tight connection with PVC foil waterproofing – this guarantees the safety and durability of the connection. The set includes a leaf basket that prevents clogging of the drain with impurities, as well as a mounting cover that facilitates and secures the installation process.

Construction and application

This inlet is extremely versatile. Thanks to the possibility of using additional elements (supporting or drainage rings of the HL350/HL65 series), it can be adapted to various roof layer arrangements – classic, inverted, ventilated or green. A flow rate of 6.9 l/s ensures effective water drainage even during heavy rainfall. The possibility of connecting a DN75 spigot or using a compensating socket of the HDPE welded system provides flexibility in the selection of the remaining installation elements.

• Wide compatibility: Possibility of adaptation to various roof structures.
• Tightness: PVC collar ensures a secure connection with PVC foil waterproofing.
• Protection against clogging: Leaf basket minimizes the risk of drain blockage.
• Easy installation: Mounting cover facilitates and secures installation.
• Efficiency: Flow rate of 6.9 l/s ensures rapid water drainage.
• Minimization of heat loss: Insulated body reduces the formation of thermal bridges.

This inlet is not only a technical element – it is an investment in long-term protection of the building against the effects of dampness and damage caused by rainwater. It will work well both in residential and industrial construction, where reliability and durability are a priority.
