Description

本発明は、耐火対策の施された樹脂製サッシ、樹脂製サッシ用形材及び樹脂製サッシ用形材の製造方法に関するものである。   The present invention relates to a resin sash having a fireproof measure, a resin sash profile, and a method for manufacturing a resin sash profile.

アルミ製のものと比較して熱伝導率が低く断熱効果が期待できることから、近年、寒冷地を中心に樹脂製サッシが普及している。その樹脂製サッシは、障子框や枠体のすべてを樹脂製サッシ用形材で構成するものの他、アルミ製サッシ用形材からなる障子や枠体の室内側にのみ樹脂製部品を取り付ける複合型のもの等があり、アルミ製サッシよりも高い結露防止性や断熱性を確保するものであった。しかしながら、樹脂製部品を使用することから、すべてをアルミ製サッシ用形材で構成するものと比べて耐火性能に劣る問題点があり、このことにより、一定の耐火基準を満たすために樹脂製形材間の隙間等、随所に耐火対策が施されている。   In recent years, resin sashes have become widespread mainly in cold regions because they have a low thermal conductivity compared to those made of aluminum and can be expected to have a heat insulating effect. The resin sash is a composite type in which all of the shoji fence and frame are made of resin sash shape, and the resin sash is made of aluminum sash shape. There was a thing etc., and it was what secured the dew condensation prevention property and heat insulation higher than an aluminum sash. However, since resin parts are used, there is a problem that the fire resistance performance is inferior compared to the case where everything is made of an aluminum sash shape. Fireproof measures are taken everywhere, such as gaps between materials.
