Roof foils
a)
Tay son
-
steam permeable and
water resistant foil
- permeable
secondary roof
covering
USAGE
It is used on tilted
roofs as additional
covering to protect
heat insulation so
that the insulation
does
not become damp. The inner side of the rolled
foil is turned
upwards against the
light (sun or
rain).
When a complete sealing is required, it is
necessary to cover
the foil by at least
10 cm and all the
connecting joints with a self adhesive water
resistant tape.
CHARACTERISTICS
Tay-son foil is
permeable on the
outside but is water
resistant on the
inside up to a water
volume
of 5cm (ONOROM B 3690) and is not appropriate
for heavier loads
(more than 10 cm of
snow) and
for hydro insulation.
The good side of the foil is its resistance to
micro organisms and
UV rays (up to 6
months)
ADVANTAGES
It is possible to
apply Tay-son
foil directly on the
heat insulation.
Tay-son foil has
very high stretch
strength.
b)
Pro-Defend-steam
permeable foil
Secondary
roof covering
Pro-Defend®
FOIL Pro-Defend®
= STEAM PERMEABLE +
WATERPROOF
USAGE
It is used on tilted
roofs as additional
covering to protect
heat insulation.
This way the
insulation
does not get damp. The inner side of
the rolled foil is
turned upwards
towards the light
(sun or rain). When a complete
sealing is required,
it is necessary to
cover the foil by at
least 10
cm and all the connecting joints with
a self adhesive
water resistant
tape.
CHARACTERISTICS
Pro-Defend foil ® is
permeable on the
outside (standard
SIST EN 1931) but is
water resistant up
to
a water column of 5cm on the inside (SIST
EN 13 111) and is
not appropriate for
heavier loads
(more than 10 cm of snow) and for hydro
insulation.
Pro-Defend® secondary covering must be
applied within 30
days.
ADVANTAGES
It is possible
to lay
Pro-Defend®
foil lay
directly on the
heat insulation.
Pro-Defend® foil has very high
stretch
strength.
c)
Steam barrier
A steam
barrier is
applied directly
above wooden
panelling or
above plaster
panels.
Steam barrier:
steam
permeability up
to 50 g in 24
hours.
Composition of raw material: 100 % PP
Size: 1,5 m x 50 m = 75 m2
d)
Steam blockade
(PVC –
polyvinyl)
Steam blockade:
is 100% non
steam permeable
Composition of raw material: 100 % PVC foil
Size: 1,5 m x 50 m = 75 m2
