Polyurea-Coated Insulation Board for Basement Light Wells
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for insulating basement walls with light wells are complex, costly, and create thermal bridges, with difficulties in locating pre-drilled holes and requiring additional on-site sealing and heavy, inflexible fiber cement boards.
Innovation Solution
A prefabricated thermal insulation system featuring a polyurea-coated insulation board that can be glued or fastened to the wall, with marked attachment points for the light well, allowing for flexible installation and avoiding direct attachment to the building wall, thus simplifying the process and reducing weight and assembly time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-drilled holes are made in the building wall for light shaft attachment, then the light shaft can be attached, but locating the holes becomes extremely difficult after thermal insulation is installed
Solution Approach 1:
The attachment points are pre-marked on the insulation board before installation. This preliminary marking action ensures that the light shaft attachment points are clearly visible and easily locatable after the insulation is installed, eliminating the difficulty of finding pre-drilled holes through finished insulation.
2Reliability
If fiber cement board lamination is used on the insulation board, then the insulation is protected, but the lamination becomes heavy and thick making installation more difficult
Solution Approach 1:
The invention changes the material parameters of the lamination from heavy fiber cement board to lightweight plastic material. This parameter change maintains the protective function while dramatically reducing weight and thickness, making the insulation boards much easier to handle and install.
3Shape
If fiber cement boards are cut to match insulation board shapes, then the lining fits properly, but cutting becomes laborious and error-prone
Solution Approach 1:
The plastic lamination material can be easily cut and shaped to match any insulation board configuration without the laborious cutting required for fiber cement boards. The material's versatility allows it to conform to different shapes and sizes, eliminating the need for complex pre-cutting operations.
4Adaptability or versatility
If insulation is provided in multiple pieces divided around the light shaft, then the light shaft can be installed, but the insulation becomes extremely complex
Solution Approach 1:
The insulation boards are provided with pre-marked attachment points that indicate where light shafts should be positioned. This preliminary marking allows installers to plan and execute light shaft installation without having to complexly divide and rearrange insulation pieces, maintaining insulation system simplicity.
5Reliability
If additional on-site sealing is performed on the insulating board, then the insulation is sealed properly, but the installation time and complexity increase
Solution Approach 1:
The lamination serves multiple functions simultaneously: it protects the insulation board, provides attachment points for light shafts, and acts as the sealing layer. By merging these functions into a single integrated component, the need for separate on-site sealing operations is eliminated, reducing installation time and complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a simpler, error-free, and cost-effective installation of thermal insulation that is lightweight, durable, and resistant to water and weather, eliminating the need for on-site sealing and reducing thermal bridges, while ensuring adequate thermal insulation and structural stability.
Implementation Method 1
Such a coating can advantageously be applied in a particularly simple manner by means of a spraying process
Implementation Method 2
Polyurea in particular crosslinks very quickly so that the drying and production times of the prefabricated insulation are advantageously reduced
Implementation Method 3
The insulation is preferably glued to the building wall
Implementation Method 4
The insulation must be water and pressure resistant, so preferably closed cell foam materials are used
