Waterproofing bitumen PGR-ro Sagitta 3.5kg gray spread GENERAL MEMBRANE

Plastomeric bitumen waterproofing membranes SAGITTA P GR 3.5 kg have been developed as an economical and effective solution for protecting roofs from weathering and moisture. The product is made from distilled bitumen modified with plastomeric polymers (attachment polypropylene - APP), which provides it with exceptional stability at high temperatures and strong summer sunlight. The mixture retains its shape and properties without flowing, which makes the series extremely suitable for our climate zone.

Unlike the basic models with glass veil, the Sagitta P modification is reinforced with non-woven polyester. This gives the membrane much better mechanical strength, tear resistance and elasticity, allowing it to absorb slight deformations of the structure. The upper surface is factory-protected with a mineral gray coating that reflects UV rays and protects the bitumen from burning out. Thanks to this, the membrane is installed as a directly exposed finishing (top) layer without the need for additional protection. Due to its lower weight (3.5 kg/m²), the roll is lighter and easier to handle, making it an ideal choice for pitched roofs, auxiliary buildings, sheds and garages.

Purpose

• Construction of the finishing (last) layer in two-layer roofing systems
• Waterproofing and repair of residential, industrial and utility roofs with lighter construction
• An excellent choice for pitched and sloping roofs (under tiles or for direct covering), where the lower weight of the material makes installation easier

Main advantages

• Good tear resistance: Polyester core provides greater tensile strength compared to glass veil
• Reliable UV protection: Mineral grey slate effectively stops the aging process caused by the sun
• Excellent heat resistance: Withstands severe heat during hot summer months while maintaining shape stability
• Advantageous logistics and handling: The lighter weight of the roll reduces fatigue when climbing on and laying the roof
• Fast welding: The special no-sprinkler strip along the length of the roll guarantees fast, clean and 100% watertight overlaps with the torch.
