I Built a 2,000 Sq Ft Cabin With Zero Experience!

What happens here

Insulation is installed to improve the cabin's energy efficiency. The A-frame design, lacking a traditional attic, requires both spray foam insulation for an airtight seal and batt insulation for thermal barriers between the rafters and wall studs. The spray foam is applied using a DIY kit with two tanks and a spray hose, expanding to fill cavities without needing trimming. Batt insulation (fiberglass or mineral wool) is then cut and fitted into the remaining wall and ceiling cavities. This step is critical for maintaining a comfortable indoor temperature and reducing energy costs.

Goal: Insulate the cabin for energy efficiency and thermal comfort.

What they say

was my job to figure out. Based off the engineered plans, we need to have a very high R value. An RV value is just a fancy way of specifying how efficient your home's insulation is. That being said, it called for spray foam insulation and traditional bad insulation in the walls. Having no attic to crawl into, it had to be both an airtight insulation and thermal barrier insulation. The entire cost of the materials for me to insulate myself was $13,000. And primarily the most expensive part was that spray foam insulation. Fortunately enough, it was a very simple process where it's already this kind of DIY kit that has two tanks and you combine them together with one spray hose and you just spray away until it starts expanding and on its own. I didn't have to trim anything down. I didn't even have to slice anything down. Just spray on and let it do its thing. After that was completed, it was as simple as simply cutting and setting in place the bad insulation between the rafters and that section was done. It
