JARBIT V80 S40 underlay welding paper is obtained by saturation and coating on both sides of the glass veil matrix with high-quality oxidized asphalt with the addition of mineral fillers. The top side of the roofing felt is sprinkled with fine sand or chlorite-serite powder, the bottom side of the roofing felt is protected with a plastic film.
Destiny
JARBIT V80 S40 underlay welding paper is intended for making undercoat layers of waterproofing in multilayer roofing as well as horizontal and vertical insulation of foundations. Particularly recommended for insulating construction of buildings in single-family buildings (foundation walls, floors), insulation of small terrace and balcony in and for protection of wet rooms (laundries, bathrooms).
attention
Weldable roofing felt with a glass veil should not be used for roofing work and used on dimensionally unstable roofs. These roofing felt should be used in multilayer systems, at most in one layer, subsequent layers made using roofing felt on other types of warp.
Storage
Rolls of roofing felt should be stored in covered rooms, protecting the roofing felt against moisture, sunlight, away from the heater. Rolls should be stored upright in one layer.
Transport
Rolls of roofing felt should be transported in covered means of transport, loaded in one layer, in a standing position, protected against falling over and damage.
