Which insulation is suitable for parking and carriageable inverted roofs?
High-compressive-strength XPS, such as X-FOAM® HBT 500 or HBT 700, is suitable for inverted roof systems designed to support vehicle traffic. The appropriate grade must be selected according to the loads and complete structural build-up.
Can paving be installed directly over XPS insulation?
The arrangement depends on the selected roof system. Paving, supports, drainage and load-distribution layers must be designed to transfer pedestrian loads correctly without damaging the insulation or waterproofing system.
Why is XPS used for treadable inverted roofs?
XPS combines low water absorption with the compressive strength required for use beneath correctly designed pedestrian roof build-ups. The insulation is installed above the waterproofing membrane and below the upper paving or load-distribution layers.
Can rainwater reach the waterproofing membrane in an inverted roof?
Yes. Water can pass through the joints between XPS boards and reach the waterproofing layer below. This behaviour should be considered when calculating the thermal performance and designing the complete inverted roof system.
What insulation is suitable for a non-treadable inverted roof?
XPS insulation is particularly suitable for inverted roofs because it combines low water absorption, thermal performance and mechanical resistance. In an inverted roof, the XPS insulation is installed above the waterproofing membrane, helping protect it from temperature variations and mechanical stresses.
What applications is X-FOAM® TRC designed for?
How does X-FOAM® EASY TEGOLA promote under-tile micro-ventilation?

POLIISO® TEGOLA DOPPIO PASSO has a compact length of 1180 mm and a width corresponding to twice the tile pitch. It incorporates two metal tile-support profiles, while its shorter format facilitates handling, storage and positioning compared with the 2400 mm TEGOLA version.
How does POLIISO® TEGOLA combine insulation and tile support?
POLIISO® TEGOLA combines a PIR insulation core with an integrated metal tile-support profile. The panel also incorporates openings designed to promote micro-ventilation beneath the tile covering, integrating multiple functions within the pitched-roof system.
What is the difference between GIBITEC® PLUS and GIBITEC® ES?
