The cost of installing insulation varies depending on what type of insulation you choose. Cheaper options aren’t necessarily bad, but they may be less effective at insulating the shed and require replacing sooner. Meanwhile, more expensive materials will last longer and can work out far cheaper in the long run. If you’re going to be spending more time in your shed and plan on living in one place for many years, then a more expensive option can be a good investment. On the other hand, cheaper materials like bubble wrap insulation are better in the short term and are less of a hassle to install and remove.
