我在哪里可以买到eps泡沫板绝缘材料？
Brian Mason|Posted in一般的问题on
I’d like to insulate my walk-out basement this summer (one wall below grade, one above, one halfway), thinking of using foam board glued to the cinder block walls, with a framed wall and fiberglass or rock wool batts up against it.
我是否对此应用程序有很好的替代品？EPS听起来很伟大 - 更便宜，更少的GWP - 但我找不到未乘以的EPS泡沫板。似乎只有XPS和Polyiso很容易获得。（面对，车库门绝缘套件除外）
任何提示或建议非常感谢。谢谢！

奇怪的是，Craigslist似乎是最可靠的选择。这是一个例子：

在房屋建筑供应股票我打电话nsulation, or specialty insulation suppliers. If those places don’t have stock, they’ll be able to order it for you.

You could also check with this manufacturer and ask them for distributors in your area:https://www.foam-control.com/foam-control/。
Thanks all! I’ll check those out. Also curious if you know the status of current manufacturing of XPS, I believe new lower GWP processes should be coming into play around now.
我没有听过关于美国XPS的修订吹代理的任何进展。在欧洲，他们一直在使用低GWP吹药，而美国制造商是凯奇的关于他们的化学，但我相信当其中一个人开始使用较差的吹代理时，我们会听到它。（该更改已被授权为1/1/2020，但该规则由上诉法院击中。）
谢谢迈克尔 - 令人失望但并不令人惊讶。
New sub-question, I got a proposal for spray foam sealing of the rim joists. I had about decided not to do this (and just do it myself with foam board, Great Stuff, and rock wool), but the price is coming in quite reasonable. Is my understanding correct that all spray foams now use low GPW blowing agents? Is that synonymous in practice with HFO's? If it's not the case that everyone uses them now, what can I ask my potential contractor -- simply , what blowing agents do you use?
I greatly appreciate everyone's expertise here. I'm finding the options and details surprisingly complex for such a modest DIY project and you're all a huge help!
user-7700882,
根据您的位置，墨水和Homedepot在4x8种不同的厚度中的股票EPS。培火似乎在价格和品种方面有点更好。

user-7700882, while all spray foam manufacturers now have a low-GWP, HFO-blown option, many installers are still using HFC-blown foam. Some markets are ahead of others. It's a client-driven issue so it's important to ask for it. You should be able to simply ask for HFO-blown foam, but I would also ask for the product name and double check that it's actually HFO-blown. Also try to get them to show you the barrels of raw product to ensure they are using what they told you they would use. (Lessons learned the hard way...)
大多数泡沫公司宣布他们的产品具有“零臭氧耗尽潜力”。这没什么可吹嘘的;它只是意味着他们没有违反十年前建立的法律，而不是与GWP直接相关。
建筑是一个有趣的领域。在建造房子时可以简单，建造一个好房子逐渐变得更加复杂。这并不意味着我们不应该建立更好的房屋，但在他们成为问题之前，需要了解所有选项和潜在陷阱需要时间。
公司（天气印章）表示，他们使用Demilac产品。它看起来像Demilac有一个HFO封闭的细胞产品。该提案是使用开放式电池喷雾泡沫（我认为在地下室的边缘托梁可能会更好，但我不确定），它看起来并不像Demilac有一个HFO吹开的开放式电池泡沫 - 但再次我不知道。我会问他，但很可能会恢复这样做，我自己是如此简单。
对于墙壁上的泡沫板（返回原始问题），它看起来如此迅速，使用EPS。这不是我想到的，但低气候影响和易于安装的结合非常诱人。
Demilac had one of the first HFO-blown closed cell foams on the market. Unfortunately like all spray foam companies they overstate their case, claiming, "Insulate without damaging the planet." Don't believe their marketing; all foam insulation comes with significant carbon emissions, which matter more on the short term that we should be looking at and not the 100-year lifecycle they base their calculations on. But I digress...
开放式电池泡沫吹入水，而不是气候损坏的制冷剂，并且需要约1/4的化妆树脂，这些树脂构成封闭的细胞泡沫。树脂中仍然存在碳排放，开孔泡沫是蒸气渗透的，这可能导致问题。但是当至少2-3“厚时，它通常是气密的，并且它比闭孔泡沫更灵活，这可以破裂它符合框架的地方。
如此迅速确实使用EPS。
Thank you again Michael! And no, I don't believe their hype. The field is way more complex than I appreciated. They have little incentive to present things clearly and lots of incentives (and ways) to mislead us, intentionally or not. The community here plays a really valuable role in cutting through all that.
I've run into a similar issue. Stucco suppliers will usually stock smaller pieces of EPS as part of their EIFS install systems, but they are almost certainly the wrong size for basement walls. None of my local lumberyard stock it.
我幸福地伸出了勇敢的当地eps，但我认为他们是区域性的。
Further up the supply chain, check out Atlas/ACH Foam, Insulfoam, Styrotech, or Polymolding, LLC (I believe they are all manufacturers). They may be able to point you towards a local distributor. You might come across Universal Foam as well, I believe they are just a distributor.
请注意，如果您在一个有墨水的区域，他们股票未达到2英寸厚的eps。我在我的轮辋上使用了这种材料，因为我在外部上有箔面对聚四肌的粘合剂，我想要更多的干燥潜力。
