AI Technical Summary
Technical Problem
Existing systems for sealing large volumes or gaps in buildings are inefficient in terms of installation time and raw material waste, particularly when dealing with small cavities such as those between a window and a wall.
Method used
A tube-like envelope with a nonwoven inner layer and semipermeable outer layer, equipped with slots and flow restrictors, is used to contain or supply foamable components, allowing the foam to expand in a desired direction to seal gaps, reducing waste and installation time.
Benefits of technology
The system effectively seals gaps with minimal material waste and reduced installation time, providing an airtight and water-impermeable seal by directing the foam expansion in the desired direction.
