2. Pitched Roof Thermal Insulation 07/11/2012 3 Pitched Roof
Thermal InsulationIn the case of usable attic we can install the
insulation in the following ways:between the raftersbetween and
under the rafters KI PITCHED ROOF SYSTEMSabove the raftersThe
thickness of thermal insulation and its placement depends on:
required thermal insulation performance, roof pitch, rafter height,
type of roof cladding used, type of roof membrane used. 07/11/2012

barrierinstalled between two thermal insulation layers. The ratio B
/ Pitched roof ridge sectional view with vapour barrierof the
insulation between the rafters (above the vapour installed under
the thermal insulation layersbarrier) to the insulation under the
rafters (below thevapour barrier) should be 5:1. Recommended

the entire height of the rafters?In the case of using the highly
water vapourpermeable roof membrane - the thermal insulationin form
of the GMW with Ecose Technology canbe installed at the entire
height of the rafter.When full hard boarding or low permeable
roofmembrane is installed over the thermal insulationof the GMW
with Ecose Technology then aventilation gap of ca. 2.5 cm must be
left under theboarding. 07/11/2012 8 4

features the highest fire reaction class A1 which means that the
pitched roof products are NON-COMBUSTIBLE The requirements
regarding fire reaction class contained in the Construction Law The
EI 30 fire resistance class is already provided by installation of
the GKF plasterboard (e.g. Knauf) of 12.5 mm thickness, on the
inside surface of the roof The EI 60 fire resistance class is
already provided by installation of the GKF plasterboard (e.g.
Knauf) of 25 mm thickness, or fire-resistant board 18+15 mm (e.g.
Knauf), on the inside of the roof07/11/2012 23 PICHED ROOF SYSTEMS
