Connection Profile With Compressed Sealing Tape For Facade Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for sealing the horizontal transition between a plaster-coated facade and a roof or attic cover, particularly with thermal insulation, are labor-intensive and prone to leaks, allowing moisture and rainwater to penetrate the facade structure, causing long-term damage.
Innovation Solution
A connection profile with a base leg for inserting between the component and thermal insulation, featuring a receptacle for a sealing tape held in a compressed state by a removable means, a plastering leg with a drip edge, and a weatherboard forming an acute angle, which simplifies assembly and ensures effective drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If joint sealing tapes are used between the plastered facade and the adjacent building component, then sealing is attempted, but the installation is quite complex and requires qualified professionals
Solution Approach 1:
The connection profile is divided into distinct functional segments: a base leg for insertion between component and insulation, a sealing leg with compressed sealing tape, a weather leg for drainage, and a plastering leg for finishing. This segmentation allows each part to perform its specific function independently, simplifying the overall installation process while maintaining reliable sealing.
Solution Approach 2:
The connection profile acts as an intermediary element that mediates between the plastered facade and the adjacent building component. It provides a standardized interface that simplifies the connection process and ensures proper sealing and drainage without requiring complex installation procedures or qualified professionals.
2Reliability
If sheet metal profiles are used to form enclosing units around the upper edge of thermal insulation, then sealing is achieved, but the attachment effort is relatively large
Solution Approach 1:
The profile material is changed from traditional sheet metal to plastic, which allows for easier manipulation and attachment. The plastic material can be simply pressed into place or attached using standard fasteners, significantly reducing the attachment effort and installation time while maintaining the required sealing functionality through the compressed sealing tape mechanism.
3Reliability
If compressed sealing tapes are used in U-shaped recesses, then sealing is provided, but precise adhesive fastening is required before insulation installation
Solution Approach 1:
The sealing tape is pre-compressed within the U-shaped recess during manufacturing, creating a ready-to-use sealing element. During installation, the connection profile is simply inserted into the joint between the component and insulation board, and the pre-compressed sealing tape automatically engages to provide the seal, eliminating the need for precise adhesive fastening before insulation installation.
4Reliability
If connection profiles with sealing elements are used, then sealing is attempted, but rainwater and moisture cannot be adequately drained away
Solution Approach 1:
The drainage function is extracted as a separate weather leg that projects from the connection profile and forms an acute angle with the plastering leg. This dedicated drainage element collects and directs rainwater and moisture away from the sealing interface, preventing moisture penetration while maintaining the sealing effect of the compressed sealing tape.
