Izobit ULTRA TOP

Izobit ULTRA TOP is the latest SBS torch-on membrane from IZOBUD, designed especially for professional contractors, architects, and investors who demand top-level quality and durability under all conditions.

This membrane was developed for buildings exposed to extreme weather and heavy mechanical loads. With a 300 g/m² reinforcement, a minimum thickness of 5.6 mm, and an extended thermal resistance range (-30°C to +120°C), ULTRA TOP sets a new benchmark in the class of top-layer membranes.

Why choose ULTRA TOP?

✅ Reinforced base 300 g/m²

Superior mechanical strength – tensile strength of 1200 N (longitudinal) and 1000 N (transversal).
Heavy-duty reinforcement ensures long-lasting performance, even under significant temperature variations and substrate movement.

Higher resistance to mechanical damage.
Better coverage of substrate irregularities.
Structural stability of the roofing system.
One of the thickest SBS membranes available on the market.

Maintains flexibility even in extreme frost and does not soften under high heat.
A crucial advantage in moderate climates, where roofs are exposed to both harsh winter and intense summer sun.

Withstands 450 N in the nail puncture test.
Reduces the risk of accidental roof damage during installation and long-term use.
