General Properties
The membrane is made from High
Density Polyethylene (HDPE). It has
excellent mechanical properties. The material has chemical resistance to
all common chemicals, acids, alkalis and salt solutions, to mildew,
bacteria and penetrating roots. The membrane is stabilized against UV
radiation. The studded membrane is produced in two basic stud heights - 8
and 20 mm. The profiled impermeable membrane separates a building from its
surroundings to protect it. The studded membrane creates a clean air
blanket. To join separate sheets easily by welding the membrane has 55 -
80 mm wide flat edges.
Quality Assurance
Our internal Membrane manufacturing quality assurance system was designed
to control the quality of the product. The supervision of the membrane
quality is subject to testing at an independent institute, ITC Zlín. The
product is certified. The produt is manufactured in accordance with the
company’s ISO 9001 quality system procedures.

Handling and Transportation
Procedures
Transportation must be undertaken by suitable, clean vehicles. During loading and unloading of the membrane it is necessary to be very carefull to avoid mechanical damage. Rolls of the studded membrane are transported vertically (standing) in bulk or on pallets. Rolls must be secured against movement. The product can be stored vertically in protected areas
(halls).
Joining
a) joining of sheets - longitudinal and transversal simple joint
Apply double sided JUNOP Tape SP 03 05 between the first and second rows of studs to one membrane
un-rolled on a flat surface; removing the protective paper from the tape after it is
applied. Then lay the second membrane onto the exposed tape, taking care to
ensure that the first row of studs fits together with lower row, and press the two sheets
together. Complete the joint by sealing it with a layer of single sided butyl rubber tape JUNOP K 03 18.
b) joining of two sheets - double joint
Apply two parallel pieces of double sided JUNOP Tape SP 03 05 to one membrane
un-rolled with one tape between the first and
second rows of studs and the second tape between the second and third rows. Then lay the second membrane on top so that the two rows of studs fit
together. Press the joint properly.
c) joining of sheets with overlap
To form a 20 cm to 30 cm wide overlap lay both membranes down on a flat surface so that the rows of studs fit
together. Then seal the overlap edge with one-sided JUNOP Tape K 03 18.
d) Welding by using, for example X84, TRIAC (Leister) welding
machines, extruders
1. welding of Junop sheets (at standard widths 1,88 m and 2,35 m) - lay sheets of membrane side by side on a prepared surface
(smooth edges overlap) and weld them together
2. welding of details (corners, cut-throughs) - use extruder
