NEXALON TPO 1.5 WITHOUT REINFORCEMENT
Weather-resistant synthetic TPO membrane.
Product variations:
NEXALON TPO 1.5 WITHOUT REINFORCEMENT is a synthetic membrane made of TPO polyolefin, manufactured by extrusion. It is weather- and UV-resistant.
Scope
- Used for the finishing and formation of finishes at singular points of the roof (protruding or incoming angles, corners, drainage cups, skylights, pipe exits, masts, etc.) on flat roofs made with NEXALON TPO type membranes.
Advantages & Benefits
- High movement capability.
- High tensile strength.
- High resistance to piercing.
- Great elasticity.
- Very high durability with respect to possible degradation due to chemical causes.
- Very good resistance to micro-organisms, rot, mechanical impact, natural ageing and swelling.
- Allows for adaptation to any type of geometry.
- Has good piercing protection from possible mechanical damage, derived from the occasional pedestrian traffic typical of flat roofs.
Instruction for Use
Preparation of the substrate:
- The surface of the base substrate shall be resistant, uniform, smooth, clean, dry and free of foreign bodies. In the case of thermal insulation, the boards shall be laid in a grid and without gaps of more than 1 mm between boards.
- Polyester geotextiles, type DANOFELT PY 300 or higher, shall be used as a separating or protective layer.
- Before the membrane is laid out, the membrane shall be mechanically fastened to the horizontal plane and to the vertical face. In the event that the sheet experiences a dimensional stability variation ≤ 0.09%, anchoring to the horizontal plane would not be necessary.
- The horizontal plane profile shall be installed as close as possible to the angle and shall never be located at a distance greater than 20 cm from the confluence or junction. In the vertical plane the profile is fixed so that the membrane rises a minimum of 20 cm above the surface of the pavement. The membrane is welded to the profile in the horizontal plane. A strip of sheeting is then welded to the profile of the vertical facing and overlapped and welded to the membrane in the horizontal plane. In this solution, the sheeting that goes up the vertical face must have the same characteristics as that of the horizontal plane.
- The joint between the profile fixed to the facing, and the masonry facing, is always sealed with an elastic and rot-proof mastic.
- Where the roof meets vertical faces and elements passing through the membrane, the membrane must rise at least 20 cm above the level of the finished roof, or higher if necessary, so that the upper edge of the membrane is always above the maximum foreseeable water level on the roof.
- Point drains and ventilation pipes must be located at least 50 cm away from any protruding roof elements (vertical walls, coffers, chimneys, etc.).
- The joint between sheets shall be made by means of thermoplastic welding, with a hot air welder. The overlaps shall be at least 5 cm and the welding of the lower sheet with the upper one shall be at least 4 cm. Immediately after welding, the joint shall be pressed with a roller, thus ensuring a homogeneous joint. To verify the joints, a physical check shall be made using a blunt metal needle (with a rounded tip with a radius between 1mm and 3mm), passing it along the edge of the joint.
