System for thermally insulating and controlling the temperature of a room and/or roof of a building
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermal insulation systems for buildings face challenges in preventing moisture damage, particularly when external insulation is used, as they can move the dew point into the wall, leading to potential moisture penetration and damage, and existing solutions that address this often compromise thermal insulation properties or require significant investment.
Innovation Solution
A system that attaches thermal insulation to the inside of external walls or roofs, creating a cavity into which temperature-controlled air is circulated, allowing heat to be transferred to the paneling and stored, thereby regulating room temperature and preventing moisture damage through controlled air flow and heat distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If thermal insulation is installed on the exterior of building walls, then thermal insulation performance is improved, but moisture penetration risk increases due to dew point shifting into the wall
Solution Approach 1:
The patent inverts the conventional approach by installing thermal insulation on the interior side of the wall rather than the exterior. This reversal prevents the dew point from shifting into the wall structure, eliminating the moisture penetration risk while maintaining thermal insulation performance. The interior insulation is combined with a cavity and cladding system to manage moisture and heat effectively.
Solution Approach 2:
The patent introduces a cavity between the interior insulation and the cladding as an intermediary element. This cavity serves multiple functions: it allows for moisture management, provides an air circulation path, and maintains the effectiveness of the thermal insulation while preventing moisture accumulation in the wall structure.
2Object-affected harmful factors
If a vapor-tight layer is installed on the room-facing side to prevent moisture penetration, then moisture protection is improved, but thermal insulation properties are reduced
Solution Approach 1:
The patent uses a vapor-permeable membrane instead of a traditional vapor-tight layer. This membrane allows water vapor to pass through while still providing moisture protection, thereby maintaining thermal insulation properties. The membrane is integrated into the cladding system, allowing it to perform both moisture management and thermal functions without compromise.
3Object-affected harmful factors
If calcium silicate boards are used for vapor-permeable insulation, then moisture protection is improved, but investment cost and reduction in thermal insulation properties increase
Solution Approach 1:
The patent creates a multi-functional system where the cladding serves multiple purposes: it acts as a moisture barrier, a thermal mass for heat storage, and a surface for the heating system. This eliminates the need for expensive specialized materials like calcium silicate boards, as the regular cladding materials perform all necessary functions including moisture protection and thermal regulation.
Solution Approach 2:
The patent combines several functions into a single integrated system: thermal insulation, moisture protection, heat storage, and surface heating are all merged into one system comprising interior insulation, cavity, and cladding. This integration eliminates the need for separate expensive components and achieves cost-effective moisture protection without compromising thermal insulation.

AI summary
The invention relates to a system for thermal insulation and temperature control of a room (1) and/or roof (23) of a building with at least one exterior wall (5), on the inner surface of which, facing the room (1), thermal insulation (6) is arranged over its entire surface. To improve the thermal insulation in the area of the exterior wall (5) and simultaneously enable surface heating, according to the invention, a sheathing (7) is arranged at a clear distance from the inner surface of the thermal insulation (6), forming a planar cavity (8), wherein the cavity (8) has at least one first opening (10, 10', 22) and at least one second opening (20, 24).The system according to the invention further comprises a temperature control device (12) for temperature control of air (17"), wherein the temperature-controlled air (17') can be supplied to the cavity (8) via the at least one first opening (10, 10', 22) and, after transferring heat energy to the covering (7), can be discharged from the cavity (8) as cooled air (17") via the at least one second opening (20, 24).
