波形沥青防水板在坡瓦屋面中的应用

The Application of Corrugated Bitumen Sheets on Sloped Roofs

波形沥青防水板作为下覆层在坡瓦屋面中应用,除具防水功能外,同时还能通风、除湿、隔热。本文指出波形沥青防水板在国外可与任一种硬质瓦配合使用,已广泛应用;在国内目前尚无相应的产品技术标准,其抗荷载能力的实验标准与方法亦需完善;实际采用时,应注意产品性能受其生产工艺的影响。

Corrugated bitumen sheets can be used on sloped roofs as covering layer under roof tiles. They are waterproofing and can make the roof ventilated, dry and insulated. The article points out the corrugated bitumen sheets can be widely apphed with any type hard tiles in foreign countries, but there is no relevant product standard in China and the test standards and methods for tiles＇ ability to resists loads needs to be improved. It should be noted that the performance of the products is influenced by the production process in the selection of the sheets.
