NEXALON TPO SLEEVE

About this product

A TPO base fitting for pipes. Compatible with tubes that have a diameter of 75-125 mm. Designed for all NEXALON TPO membranes.

Used as a complement to waterproofing with synthetic sheets made of TPO, provided with a flange to which the waterproofing membrane sheet is welded.

Good adaptability to any irregularities of the substrate.

Compatible with all synthetic sheets in the NEXALON TPO range.

Great elasticity.

Provides highly reliable welding and tapping.

Solves the connection to masts, ventilation pipes, pop-up supports, etc., easily and safely.

The surface of the base substrate must be strong, even, smooth, clean, dry and free of foreign bodies.

Fully extend the PVC membrane, pierce it proportionally to the diameter of the drain, insert the nozzle into the pipe, hot-air weld the crown to the membrane and insert the hose clip.

The fastening element must be suitable for the material of which the support is made. The tensile strength of the fastener to the load-bearing support shall be checked to ensure proper mechanical attachment. The fasteners must withstand a permissible tensile load greater than 600 N per anchorage point. As the membrane is the outermost element of the waterproofing system, its stability against dynamic wind pressure must be calculated according to the shape of the building, its height above ground, its topographical situation, and the specific roof area.

In renovation projects on old waterproofing, it may be necessary to remove existing materials or to use suitable separating layers.

The weldability and quality of the weld depend on atmospheric conditions (temperature, dampness), welding conditions (temperature, speed, pressure, pre-cleaning) and on the surface condition of the membrane (cleanliness, dampness). Therefore, the hot air machine must be adjusted to obtain a correct assembly.

To avoid chemical incompatibilities, a DANOFELT PY 300 or higher geotextile separating layer shall be placed between the membrane and the geotextile: Bituminous products, synthetic PVC and EPDM, extruded (XPS) or expanded (EPS) polystyrene-based products, rigid or foamed PU, etc.

After the surface has cooled down, the welds shall be carefully checked by means of a punch. If any irregularity is detected in a hot air weld, it shall be reworked with the same procedure as described above.

Appropriate safety measures must be taken as welding work can give off fumes which can be irritating.

The product must be stored in a dry place protected from rain, sun, heat and low temperatures.

This product is not toxic or flammable.

Easy to cut to adapt the dimensions to the work.

No welding work should be carried out when the ambient temperature is lower than -5ºC for hot air welding, nor lower than + 5ºC for welding with THF or with Adhesives.

It shall be kept in its original packaging, in a horizontal position and all rolls parallel (never crossed), on a flat and smooth support.
