Product Info:

The four-layer SAFEBUILD U230 underlay membrane can be used universally in exterior and interior areas for roofs, façades and drywall construction. The membrane optimizes the wind tightness of the construction and stops rain. The aluminum foil protects against the penetration of warm air in summer and cold air in winter.
