AI Technical Summary

Benefits of technology

The sheet effectively prevents root growth, minimizes thermal conductivity, and enhances thermal insulation, extending the lifespan of the sheet and building structure while reducing maintenance costs and construction time.

Problems solved by technology

But the nonwoven fabric takes on a form susceptible to penetration of the growing roots and thus cannot provide a good root barrier function.
The PE film has a joint portion to which an adhesive or an adhesive tape is applied, so the joint portion becomes a main weak point ready to form a water path because of its poor adhesion stability, allowing the penetration of plant roots and thus causing a deterioration of the root barrier function.

Abstract

Disclosed therein is a sheet for green roof that includes a copper or aluminum thin film or a nonwoven fabric having a predetermined thickness firmly laminated on both sides of a glass fabric having a predetermined area through an adhesive to prevent the root growth of plants and maximizes insulation from moisture, thermal insulation, and reduction of thermal conductivity, thereby extending the lifetimes of the sheet, the waterproof layer and the building structure.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a sheet installed not only to prevent the root growth of plants but also to provide a waterproof seal when vegetating a building roof, and more particularly, to a sheet for green roof including copper or aluminum thin films or nonwoven fabrics firmly laminated on both sides of a glass fabric using an adhesive to eliminate moisture and maximize thermal insulation in vegetating a building roof.[0003]2. Background Art[0004]As well known, green roofs involve growing plants on rooftops for providing a vegetation environment in an urban area to minimize air pollutions and provide the urban area with beautiful views. To make the green roofs safe and stable, it is required to establish a “safe foundation” on the building structure where the green roofs are provided (that is, “planted”), as designed so that the vegetation does not affect the structural stability and durability of the building.[00...
