欧洲窗户和NFRC
我们正在研究Windows为我们的新家居建筑或桑迪或。我们想使用铝欧式倾斜和转动窗口，但我注意到我们收到的许多引用没有NFRC认证（Aluprof，Aluprof，Aliplast，Mito，Mitra等）。
I contacted our Building department and they stated that an NFRC certification sticker is required, with a few exceptions, none of which seem to apply to us.
It seems that a lot of folks use European windows, and don’t see the lack of NFRC certification discussed much on this forum, so I am wondering if I’m missing some (legal) way to get these past an inspector, or if it’s just that other jurisdictions are more lenient than mine? It’s frustrating because most of these windows have much better performance than traditional windows we see going into new houses here (Milgard), so I wonder if there’s some way to make this work.

IMO there are two primary reasons for a Euro window company to avoid NFRC certification.
首先，基于销售北美的潜在销售量来获得和维护认证相对昂贵且耗时。
Second, certifying to NFRC will result in an apples to apples comparison with their North American counterparts, and their performance values will not look as good as advertised when only converted from the European certification.
There are exceptions such as Zola, Intus, Oknoplast, and others who have certified NFRC, so you could look for companies that have the certification, or failing that there are North American companies that sell tilt/turns that are every bit as good as the imports, in part because they are likely using Euro hardware and sometimes sash/frame components in their window construction.
谢谢格雷格,这是有意义的。我理解那t certification process has its downsides (actually I was told that Aluprof is currently getting NFRC-certified, but probably not in time for our project). And I'm also investigating Zola and other NFRC companies, as well as the domestic suppliers (e.g. Alpen, Reynaers)).
我的真正问题主要是关于人们如何在国内建设中使用非NFRC窗口，因为大多数司法管辖区都需要NFRC贴纸。我的窗口经销商表示，他们从未在这里使用非NFRC认证窗口的问题，他们只提供“热报告”。但不同的供应商表示，督察可能拒绝这一点，总有风险。我只是想了解如果在这里使用非NFRC Windows的可靠方法，或者它始终是风险吗？
我认为在大多数情况下，检查员看到了数字和施工质量，并跳到了这一结论，即在代码上方，很高兴签字。
There may be cases in which people have had to use alternatives in the code to prove compliance with overall thermal performance with energy modeling rather than compliance with the prescriptive specifications.
如果你没有结婚铝倾斜/转的想法，那么向北京进入公元前，那里有一些非常好的橱窗制造商，倾斜/转向，正如我之前所说的那样，每一都是好的进口。两个立即想到的是史诺特和卡斯卡迪亚。
当我建造我的房子时，我选择innotech乙烯基倾斜/转弯，超过15年后，他们看起来像是他们安装的那天。虽然我个人真的不认识Cascadia，但我已经阅读并听到他们的读写是非常积极的。
直接到您的问题，您几乎肯定会收到有关您购买的任何高端（并不总是下端）窗口的能量性能信息，即使它不是NFRC，也是如此。我同意，大多数检查员都会在窗口质量上看那种绩效信息，并在没有NFRC标签的情况下接受您轻松超越代码要求。
接受这一事实，如果绩效证书基于欧元测试转换为北美术语，那么结果似乎比他们真正的时间更好，当测试到NFRC要求时，我怀疑少数人有任何真正的知识。
