Stone Wool Insulating Panels With Profiled Grooves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulating panels made of mineral wool, particularly stone wool, face challenges in securely fixing to concrete slabs without compromising their insulating properties and require complex manufacturing processes, including the use of numerous grooves that impair thermal insulation and are difficult to produce.
Innovation Solution
The insulating panel features a body composed of two layers of stone wool with fibers oriented parallel to the main surface, incorporating a limited number of profiled grooves that allow for strong fixation to the concrete slab without compromising thermal insulation, using grooves with specific profiles that facilitate concrete pouring and provide mechanical strength for reversible deformations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If helical spring or corkscrew anchoring elements are used to fix panels to concrete slabs, then secure fixation is achieved, but lengthy and tedious operations of fitting anchoring elements are required
Solution Approach 1:
The anchoring function is built into the panel structure itself through pre-formed profiled grooves during manufacturing, eliminating the need for separate anchoring element installation. The grooves are created in advance and simply need to be filled with concrete to achieve anchoring, transforming a complex post-installation operation into a simple pouring step.
2Reliability
If numerous grooves are provided in insulating panels for anchoring, then strong fixation to concrete slabs is achieved, but thermal insulation performance deteriorates
Solution Approach 1:
Instead of distributing many small grooves across the panel surface, the invention uses a limited number of profiled grooves with optimized dimensions and spacing. The grooves are strategically positioned and sized to provide sufficient anchoring surface area for concrete interlocking while minimizing the total volume of material removed from the insulating panel, thus preserving thermal insulation performance.
3Strength
If fibers in insulating panels are oriented perpendicular to the main surface to withstand pressure, then mechanical strength is improved, but thermal insulation value in the perpendicular direction deteriorates
Solution Approach 1:
The invention uses a composite structure combining stone wool layers with strategically oriented fibers. The fibers are arranged parallel to the main panel surfaces rather than perpendicular, and the mechanical strength is achieved through the combination of the stone wool matrix, the fiber orientation within the planes, and the profiled grooves that provide anchoring reinforcement. This composite approach maintains thermal insulation while achieving necessary mechanical strength.
