Combined Sealing and Insulation System for Window Sills
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window sill sealing and insulation systems face challenges in preventing moisture penetration between the insulating element and the structure, leading to a loss of insulating effect, especially when thermal insulation is installed under metal window sills prone to driving rain.
Innovation Solution
A combined sealing and insulating system featuring a sealing foil with an insulating element and adhesive elements, where a second sealing film forms a watertight or airtight layer to seal the joint between the structure and the insulating element, ensuring that the insulation is properly laid and protected from moisture during installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If thermal insulation is installed under the window sill, then insulation effect is improved, but moisture penetration risk increases causing insulation to become damp
Solution Approach 1:
The sealing system is divided into multiple functional layers: a first sealing membrane for primary waterproofing, a second sealing membrane specifically for sealing the joint between building element and insulating element, and adhesive elements for secure attachment. This segmentation allows each layer to address specific moisture penetration paths while maintaining insulation effectiveness.
Solution Approach 2:
The sealing membranes and adhesive elements are pre-assembled into an integrated unit that is installed as a complete system. The second sealing membrane is pre-positioned to seal the critical joint area between the building element and insulating element before moisture can penetrate, preventing dampness before it occurs.
2Object-affected harmful factors
If sealing membrane is installed above insulation to protect from moisture, then moisture protection is improved, but installation complexity increases
Solution Approach 1:
The sealing membranes and insulating element are combined into a single integrated assembly unit. The first and second sealing membranes are attached to the insulating element along with adhesive elements, forming one complete component that is installed together. This merging eliminates the need for separate installation steps and reduces overall system complexity.
Solution Approach 2:
The insulating element serves multiple functions: it provides thermal insulation, acts as a substrate for mounting the sealing membranes, and works together with the adhesive elements to create a unified sealing system. This multi-functionality reduces the number of separate components needed and simplifies installation.
3Ease of operation
If sealing system is simplified for easier installation, then ease of operation is improved, but moisture sealing reliability may be compromised
Solution Approach 1:
The critical sealing configuration is pre-assembled during manufacturing, with the second sealing membrane positioned to seal the joint between the building element and insulating element, and adhesive elements pre-attached. This preliminary action ensures proper sealing geometry is achieved without requiring complex field installation procedures, maintaining both simplicity and reliability.
Solution Approach 2:
The sealing system is designed so that the first and second sealing membranes work together at the same functional level to provide comprehensive moisture protection. The second sealing membrane specifically addresses the joint area, creating an equipotential sealing barrier that maintains reliability while keeping the installation process straightforward through the integrated design.
