干燥机通风口到外部 - 建筑物的材料

约翰·沃尔斯| Posted inBuilding Code Questionson

I’m trying to find a better way to get the vent through the wall in a brick veneer home—new construction.
大型商店的标准廉价薄壁通风孔最终在砖安装期间有些压缩,因此很难替换。同样,将未来的任何更换密封到砖后面的水壁障碍也是不可能的。我想,当您必须更换挡板部分时,只能在砖线上切下它,但是随后您有一个奇怪的形状可以匹配。

因此,我匆忙地将砖块放进去,我放入了4英寸PVC(4.5英寸OD)的一块,以为我可以将排气软管绑在上面。它是电动机,所以我决定如果衣服可以变热,那么PVC也可以。我与几位不喜欢它的代码检查员进行了检查,但不确定它是否禁止代码。请注意,我将PVC管放在附着在墙上的聚合物屋顶通风孔中,这样我就可以将PVC换成PVC,如果它被认为不合适,并且仍然保持我的水障。

所以,我的问题 - pvc满足代码吗?
Possible remedies–put the cheap thin wall metal device through the ID of the PVC (would that meet code?), or replace the PVC with a piece of thin wall stainless pipe.

塑料挡板外部会满足代码吗?金属非常嘈杂,在大风中拍打。

在相关问题上,我使用3英寸PVC(3.5英寸OD)通过侧壁进行浴风扇通风孔。这里唯一的问题是在外部找到金属落水器/错误屏幕以匹配大小。除了定制的金属外,这里有什么建议吗?请注意,这些管道被粘贴到水壁上以保持密封。

    我们的住宅代码规定了干燥机排气管的规定,应由0.016英寸厚的刚性金属制成 - 配备了后草减速器。还有更多,但这解决了您的主要关注点。我建议您与干燥机制造商联系以获取更多信息。如果您可以让制造商与您的PVC一起使用,请将该信息带到当地建筑部门,并要求首席建筑官员将其视为替代材料。

    约翰,
    2006 IRC,M1502节,“干衣机排气”,特别是M1502.5:“管道结构。排气管应以最低0.016英寸厚的刚性金属管道构造,具有光滑的内部表面,其关节朝着方向延伸空气流。排气管不得与薄层螺钉或固定方式连接到管道中。”

    So, if I leave the PVC pipe in tact, and install the .016" thick metal duct inside the PVC, it sounds like that would meet code. Right?
    Does flapper have to be metal?

    约翰,
    All code interpretations are local -- subject to the ruling of your local inspector.

    For the outside part, look at the Heartland Dryer Vent. It's solid construction, will last, won't have the noise of a light metal flapper, and provides backdraft protection.

    谢谢,我刚刚订购了一个心脏地带,大约有20美元。它似乎是塑料的,并且有良好的评论。代码是否允许使用此止回阀的塑料?

    Hi guys,

    I found this innovative dryer vent cap while browsing around. It actually looks like quite a winner. What are your thoughts?

    (“低调”似乎是他们的最新型号。http://www.p-tecproducts.com/index_files/page2326.htm

    Cheers,

    JW,我想您会喜欢心脏地带。它是坚硬的塑料,也不是脆弱的。有人可能会说它比普通的墙帽具有更明显的配置文件,但我更喜欢功能。漏水的设备比我一段时间后不会注意到的东西更困扰我。我画了矿山绿色的亨特·格林(Hunter Green),以匹配房屋装饰。为此,我使用了Krylon融合喷雾剂可以绘画,结果看起来像是以这种方式交付的。

    我不能确定帽子可以是塑料并满足代码,但我怀疑可以是,因为许多这些瓶盖产品都是塑料。不同之处在于,它可以在外部清洁,而管道通常不能。Code说,没有紧固件穿透以避免棉绒堆积,我怀疑金属的代码也是要避免从静电电力中收集皮棉,塑料管可能会发生。正如马丁说的那样,问检查员。或者只是安装它,看看他是否注意到它。

    DV, my thoughts on that Tec Products cap is that it still could be subject to lint buildup at the hinge, as happens with typical hinged flappers. I can't say for sure that the product would or wouldn't be apt to collect lint, but I don't trust advertising. I do know that the Heartland cap can collect lint at the floating shuttle (I think the Tec ad must be referring to that cap). My daughter bought a house that has one, and when I popped the cap off it looked like it had never been cleaned. However, the lint buildup was uniform around the perimeter of the shuttle, and it didn't prevent the shuttle from opening or closing properly to prevent backdrafting. I did clean it while I had the cap off. Overall, I like the design.
