Roof Sealing Technology

Application on the roof

BOSIG sealing solutions

Heat, cold, sun and wind will subject roofs of buildings to extreme stresses by environment and weather. 

The demands for flexibility and resistance to weathering of the sealing materials will be correspondingly high.  

BOSIG roof sealing solutions are designed to meet the demands for water-repellent, diffusion-open or vented and heat regulating properties

Our products are distinguished by their simple application, high tear strength and durability. Solutions to humidity control and the removal of residual moisture in materials such as wood will prevent damage by moisture or mould and reduce energy loss via thermal bridges.
