Multilayer Panel with Polymeric Reinforcement for Thermal Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multilayer building panels with thermal insulation properties face challenges in balancing cost-effectiveness, durability, and resistance to environmental factors such as micro-organisms, bacteria, vapour, and condensation, particularly in agricultural applications, where fibreglass or metal-backed panels are either expensive or require additional protective coatings.
Innovation Solution
A multilayer panel construction featuring a main insulation layer sandwiched between reinforcement layers, where one reinforcement layer is made of polymeric materials like HDPE or LDPE, which are flexible, resistant to environmental attacks, and can be combined with fibreglass or metal backing for enhanced durability, and treated for improved adhesion and sealing properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fibreglass or metal backing layers are used in sandwich panels, then resistance to micro-organisms, bacteria, vapour and condensation is improved, but production cost increases
Solution Approach 1:
The patent uses a composite structure combining bituminous felt paper (flexible, economical layer) with a protective coating layer containing biocides and corrosion inhibitors. This composite approach provides the resistance properties of expensive materials like fibreglass or metal while maintaining the cost-effectiveness and flexibility of bituminous felt paper.
2Ease of manufacture
If bituminous felt paper is used as backing layer, then production cost is reduced and flexibility is improved, but resistance to micro-organisms, bacteria, vapour and condensation deteriorates
Solution Approach 1:
The protective coating layer acts as an intermediary between the bituminous felt paper and the aggressive environment (micro-organisms, bacteria, vapour, condensation). This coating layer contains biocides and corrosion inhibitors that provide the necessary protection, allowing the bituminous felt paper to maintain its cost-effectiveness and flexibility while achieving the required resistance properties.
3Duration of action of stationary object
If fibreglass or metal backing layers are used, then durability and washability are improved, but the panel becomes less flexible and more expensive
Solution Approach 1:
The patent creates a composite structure where the bituminous felt paper provides flexibility and the protective coating layer provides durability and washability. This composite approach allows the panel to maintain the flexibility needed for building applications while achieving the durability and washability typically associated with rigid materials like fibreglass or metal.
