Making fibreglass insulation

[Snagglefoot]

I just watched an episode of How it’s Made, season 6 episode 8 and it was about making fibreglass insulation. This brand had up to 35% recycled glass. Turned out at the end, the product was R20 Fibreglass Pink for 2 x 6 walls. ( with the Pink Panther licensed trade mark).

One popular product up here is 9 inch thick R30 for use in attics for do it yourselfers who don’t want to use blown-in product. The building code for this part of B.C. is R60. People are buying the 9 inch R30 batts and putting them on top of whatever they had to end up somewhere near R50 to R60.

IIRC there's one on rockwool insulation (Roxul Canada.) which is kinda cool.


In case you were interested here is current code for climate zones in the US. Note: 13+5 is R13 interior w/ R5 exterior (rigid foam 1") etc. Of course the states are not required to adopt latest code.

I agree about rockwool. I insulated my basement with it. It’s easier to cut and does not itch like fiberglass.
