Pre-applied Sealing Material on Building Boards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional building construction methods require on-site application of sealing materials, which can be messy and labor-intensive, and often fail to provide a consistent air and moisture barrier between the interior and exterior of a building.
Innovation Solution
Pre-applied sealing material on building boards that form seals when attached to a frame, ensuring a consistent and efficient air and moisture barrier by sealing against adjacent boards or the frame, reducing on-site application mess and labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If on-site application of sealing materials is used, then labor flexibility is maintained, but construction time increases and consistency deteriorates
Solution Approach 1:
The sealing material is pre-applied to the boards during manufacturing before the boards are shipped to the construction site. This preliminary action eliminates the need for on-site application, reducing construction time and ensuring consistent sealing quality while the boards are simply installed by attaching them to the frame.
2Manufacturing precision
If pre-applied sealing material is used, then sealing consistency improves, but board manufacturing complexity increases
Solution Approach 1:
The sealing material is integrated directly onto the board surface, merging the board and sealing material into a single composite component. This eliminates the need for separate sealing applications and reduces overall system complexity despite the enhanced manufacturing process for the integrated board.
3Productivity
If pre-applied sealing material is used, then labor requirements decrease, but material cost increases
Solution Approach 1:
The sealing material is applied during board manufacturing when automated processes can efficiently apply the material with minimal waste. This preliminary action reduces overall material consumption compared to manual on-site application, offsetting the increased material cost through reduced labor requirements and improved installation efficiency.

AI summary
A board with preformed seals. In an exemplary embodiment, a sealing material is applied to at least one edge of a board to form a preformed seal on that edge. The board is configured such that when the board is attached to a frame adjacent to a another board, at least a portion of the sealing material applied to the edge of the board seals against at least a portion of an edge another board. In one exemplary embodiment, the boards are configured to seal against edges of substantially identical boards. A plurality of the sheathing boards may be installed on a building frame to form a sheathing system that provides a moisture and/or gas barrier between and interior and exterior of a building.
