With lower glass wool density (10 kg/m3) compared to the higher one (80 kg/m3) there is a substantial decrease in human toxicity, embodied carbon and acidification pushing the overall score from A to A+

One would assume the lower density to be better in every case but if you take into account the U-value and requirements of the wall, say wet module thickness it becomes more complicated]]> 2020-09-30 08:39:41 UTC https://padlet.com/sofiepelsmakers/8y1iqnelkwybvg8j/wish/790604083 https://padlet.com/sofiepelsmakers/8y1iqnelkwybvg8j/wish/790608587 Generally, we looked at different densities of glasswool and also EPS. It turns out that for the environments that need less insulation, glasswool is better and has a better impact but when it needs to be used in denser quantities than it has a much larger impact and EPS can be a better alternative for long-term impact. (more thoughts from the group in comment section)]]> 2020-09-30 08:42:14 UTC https://padlet.com/sofiepelsmakers/8y1iqnelkwybvg8j/wish/790608587 https://padlet.com/sofiepelsmakers/8y1iqnelkwybvg8j/wish/790621094 Glasswool 1 seems better in almost every aspect and needs less material. nr 2  is probably better for sound  insulation. ]]> 2020-09-30 08:49:34 UTC https://padlet.com/sofiepelsmakers/8y1iqnelkwybvg8j/wish/790621094 https://padlet.com/sofiepelsmakers/8y1iqnelkwybvg8j/wish/790623066 Woodfibre seems to outstand the rest of the insulation materials. At least on the paper.
