Semi-Rigid Vapour Barrier Corner Element for Airtight Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of vapour barrier membranes in building corners is complicated, often resulting in misalignment and potential damage during drywall installation, which compromises the seal between the interior and exterior of timber framed buildings.
Innovation Solution
A semi-rigid vapour barrier corner element comprising two elongated flat sheets oriented at a predetermined angle, with matching widths and thicknesses, and an adhesive layer for secure mounting to the building frame, facilitating airtight installation and preventing seal breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the vapour barrier membrane is manually held and stapled in the corner, then the membrane can be installed on the studs, but misalignment occurs leaving gaps between the membrane and corner studs
Solution Approach 1:
A corner element is introduced as an intermediary component between the vapour barrier membrane and the corner studs. This corner element features a corner shape with two perpendicular sides that fit into the corner space, providing a stable reference surface for membrane alignment and eliminating gaps without requiring complex manual positioning
Solution Approach 2:
The corner element is pre-installed on the corner studs before the vapour barrier membrane is applied. This preliminary action creates a ready-made alignment reference that guides the membrane placement, ensuring proper positioning from the start and preventing misalignment issues during the membrane installation process
2Reliability
If the vapour barrier membrane is installed without proper alignment, then installation can proceed quickly, but the membrane is prone to damage during drywall installation breaking the seal
Solution Approach 1:
The corner element is installed in advance to create a protective and alignment-guiding structure before the vapour barrier membrane is applied. This ensures the membrane is properly positioned and protected from damage during subsequent drywall installation, maintaining seal integrity without requiring time-consuming rework
Solution Approach 2:
The corner element serves as a protective cushion or buffer that shields the vapour barrier membrane from damage during drywall installation. By having this protective element in place beforehand, the membrane is prevented from being torn or damaged, ensuring the seal remains intact throughout the construction process
3Reliability
If a custom corner solution is developed to ensure precise alignment and prevent damage, then seal integrity is maintained, but the device complexity increases
Solution Approach 1:
The corner solution is segmented into a separate, standalone corner element that is distinct from both the studs and the vapour barrier membrane. This modular corner piece with perpendicular sides is designed specifically for corner installation, simplifying the overall system while ensuring proper alignment and protection without requiring complex integration of multiple components

AI summary
A vapour barrier corner element is provided. The vapour barrier corner element comprises a first elongated flat sheet having a predetermined length, a predetermined first width, and a predetermined first thickness A second elongated flat sheet extends from the first sheet along the length thereof and is oriented at a predetermined angle thereto. The second elongated flat sheet has a predetermined second width and a predetermined second thickness. The first sheet and the second sheet are adapted such that an exterior facing surface of each of the first sheet and the second sheet align with a respective interior facing surface of a corner of a building frame. The first width and the second width are determined such that a vapour barrier membrane can be mounted thereto in a substantially airtight manner. The first sheet and the second sheet are made such that the vapour barrier corner element is semi-rigid.
