Funnel THREE Ø50mm lateral GENERAL MEMBRANE

General Membrane Eterno 50 mm is a specialized lateral (horizontal) gutter, designed for reliable and efficient drainage of rainwater and surface water from flat roofs, open terraces, balconies and decks. It acts as a drainage siphon, providing a direct, hermetic connection between the surface waterproofing layer and the building drainage system.

The funnel is made of high-class TPE (thermoplastic elastomer). This material is characterized by exceptional elasticity, excellent adhesion and full compatibility with polymer-bitumen (APP and SBS) waterproofing membranes, allowing direct welding with a gas flame torch with an open fire, without the risk of deformation. The product is resistant to aging, ozone, UV radiation and extreme temperature amplitudes, while maintaining its flexibility and mechanical properties over time.

Purpose

• Side drainage (horizontal drainage) on flat roofs
• Linear drainage through the boards of roof terraces and balconies
• Construction of drainage transitions in modern roofing systems
• Preventing water retention in critical roof edge areas
• Professional and civil construction of buildings

Main advantages

• High heat resistance when processed with an open flame (gas flame installation)
• Excellent adhesion and 100% sealing to bitumen membranes
• Exceptional elasticity, preventing cracking when the building settles
• Complete resistance to corrosion, chemical agents and UV rays
• Long drain pipe (250 mm) for easy passage through thick side walls
• Compact and practical design for quick installation in tight spaces
