新西兰墙体保温棉安装 需要拆墙板?
在新西兰
天花板和地板下的保温棉比较容易安装,墙体的保温棉怎么安装呢?
如果是安装过保温棉的老房子,一般能维持多少年需要补充呢?
谢谢指教

Get a certified Company to do the installation, they will write the wall is exempted.
Use that certification to attached to Tenancy Agreement in future renting.

我听说有一种是在墙上打眼,然后往里面注射的。跟打针一个原理。但是不知道是不是所有的情况都能适用。
评论
我知道有一种 blown-in wall insulation。把外墙或者内墙不同的地方开洞,然后把棉絮状的保温棉用吹风机吹进去。(这种的墙里面必须要有building paper)

你讲的多年前已经有人专门研究过不好,纽村做的那家公司应该已经转行了,美国有但一般也是用在未封石膏板前,不是用在已经建好的房子上
评论
现在还有做这个的。

谢谢朋友,我是想把自己住的房子搞暖和一些,我看保温棉需要每隔10年top up一下,因为我这个房子快50年了,想说是不是再整点进去,顶上地下好弄,不知道墙里咋办
评论
你可以联系BRANZ,让他们推荐BRANZ 认证的可以做旧房墙体保温的公司。有BRANZ certified的,一般技术有保证。

那么多studs得打多少洞。。还不如多装两个空调

最近看一个美国建房电视节目,—个新建的房子不知因何不用那些保温棉,用的是喷泡沫来做保暖层
评论
我看它网站上介绍说是防水的,不需要building paper把
评论
是一个框框一个洞不....一想还真是
评论
对就是这东西,换了公司名字,正如你所讲装空调更靠谱,不过最好还是同时做顶底保暖层及双层玻璃,这玩意真的不知要打多少洞才能保证填满
评论
好像不是一个框框一个洞,没有这么夸张。具体的你可以问问。
评论
现在的新产品真的不清楚了,你可以问问。我建议你要是真的认真看进去,就找Branze多介绍几家,每家的做法都了解一下。
评论
我也看到电视上有过泡沫的。
不知道哪种好,会不会泡沫的比较不容易沉降?不容易招老鼠?但是棉絮状的circulation比较好?不是很懂这个。
评论
我觉得还是保温棉好,否则我看那些造房节目,绝大部分是用保温棉
评论
这种产品多年前consumer NZ专门做研究,认为不好,因为无法保证填好填满
评论
有总比没有强。
评论
楼上所讲装空调更好
评论
对。能换断桥铝就换断桥铝,中空玻璃用thermal spacer。铝合金导热要比墙快得多,大部分的热量都是从门窗散出去的,我们做过分析。当然现在加墙保温也不是没用,就是性价比不高。
评论
不是这方面的专家。但是我估计是,要不studs和nog隔着咋填满呢。

早有定论
An investigation into claims made for Airfoam wall insulation have resulted in the Commerce Commission issuing a warning to David Rees, a former director of two companies that marketed the product.
The commission found conduct by Mr Rees, Airfoam Wall Insulation Limited and Airfoam New Zealand Limited was likely to breach the Fair Trading Act.
Mr Rees is a former director of both companies. He remains a shareholder of Airfoam New Zealand. Airfoam Wall Insulation is in liquidation.
In its warning to Mr Rees, the commission stated that claims made about the thermal insulation value and water resistance of Airfoam weren’t backed by evidence. Marketing materials claimed the product had an insulation value of R2.9/100mm and was “hydrophobic” (water resistant) but the commission found that wasn’t the case.
It also found customers weren’t told they needed to get building consent to install Airfoam. The commission said it believed the companies and Mr Rees knew that franchisees of the product were completing work without obtaining the required consents.
The commission is not taking any further action but told Mr Rees it would take this “warning into account if you engage in similar conduct in the future”.
Foam insulation
The Building Research Association of New Zealand (BRANZ) has previously raised concerns about foam insulation.
In a 2010 report, it estimated the actual insulation value of urea formaldehdye foam insulation (UFFI) – which has been the most common type of foam insulation – was about 50 percent lower than when measured in a test lab because the product shrinks when installed.
While UFFI still insulates walls, BRANZ found it doesn’t perform as well as bulk insulation. Poor installation can also affect the thermal performance of the product. Retrofitting installation into walls now requires a building consent or specific approval from your local council that a consent is not required.

楼主你家墙漆如何,要不然你就直接把墙砸了,重新铺保温棉和石膏板,而且可以顺带可以重新安排一下电路如果设计不合理的话。我之前就是这样的,这个事儿很简单,就是铺石膏板,然后打腻子,磨平之后刷漆就好了。你别心急,一个房间一个房间的弄。我想到明年这时间你也可以住上暖和的房子了。

我换双层玻璃前读了很多文章包括大学做的研究报告,所以将钱用在换玻璃,至今不装空调,哈哈哈

明智的选择

正常来讲墙上加装保温棉要BC,不信你可以打电话去问问康嫂
评论
的确有可能需要,但是也不一定。
评论
这个东西麻烦,涉及到电线和水管。

为什么不把房子卖了买个新房子 这样 你连内墙都可以加装保温棉了。、。。。。
