AI Technical Summary

Technical Problem

Existing prefabricated house wall structures in wooden frame construction face challenges in achieving a U-value of 0.28 W/(m²K) while maintaining a reduced wall thickness, leading to excessive thickness and space inefficiency.

Method used

The use of gypsum fiber plates combined with a carrying/insulation group and interior closure plates, along with specific insulation layers and moisture-resistant barriers, reduces wall thickness while maintaining the required U-value.

Benefits of technology

The proposed structure achieves a U-value of 0.28 W/(m²K) with a significantly reduced wall thickness, enhancing space utilization and maintaining static and acoustic requirements.
