Bitumen waterproofing VGR-ro Sagitta 4kg gray spread GENERAL MEMBRANE

Plastomeric bitumen waterproofing membranes SAGITTA VGR 4 kg are made of high-quality distilled bitumen, modified with plastomeric polymers - atactic polypropylene (APP) and selected stabilizing filler. Thanks to the APP modification, the Sagitta series has exceptional resistance to high operating temperatures, UV rays and thermal aging. This makes it a perfect budget choice for geographical areas with intense and prolonged summer sunshine.

The specific feature of the Sagitta VGR model is its glass fleece reinforcement. It provides impeccable dimensional stability (the material does not shrink or expand under the influence of heat), which guarantees the correct behavior of the seams over time. The finishing top layer is made of mineral gray aggregate, which reflects the sun's rays and protects the bitumen mixture from burning out and aging. This allows the membrane to be laid as a directly exposed finishing (last) layer on the roof without the need for additional protection.

Purpose

• Construction of a finishing (top) layer in two-layer or multi-layer roofing systems
• Waterproofing and repair of flat roofs, terraces and sheds of residential and auxiliary buildings
• Applicable on pitched roofs under tiles or for direct covering where there is no heavy mechanical movement of the structure

Main advantages

• Reliable UV protection: The mineral grey coating effectively extends the life of the bitumen under direct sunlight
• Excellent heat resistance: The coating retains its shape and stability even when the roof is heated to +110°C
• Dimensional stability: The glass veil protects the membrane from deformation during sudden temperature changes
• Budget solution: Provides an optimal balance between price and long-lasting waterproofing for standard roof structures
• Easy installation: Factory-left side edge without filler for quick, easy and excellent torch welding of overlaps.
