想买R50 ceiling insulation/R24 basement insulation，Home depot只有R40ceiling insulation, Rona只有R22的basement insulation.
请问哪位知道Ottawa还哪里卖insulation的，谢谢了。

谢谢lungao.
我现在的ceiling是那种象防寒毡一样的insulation，所以我想还加那样的，自己加也好做。但就是没找到R-50的，最厚的就是R-40的。

A layer of r-40 + a layer of r-22 = r 62



basement Rigid plastic board insulations + r22 > r24
