The thermal/space blanket experiment
Have read on forums about people having luck with keeping the heat in with thermal blankets. Now I know there are real greenhouse thermal blankets that allow water to flow thru and heat to stay in…but I was too cheap for that and found on a forum a woman who keeps here greenhouse heat in with thermal blankets from a camping store.
So for a whopping $4.50 investment here we have the mountain thermal retention system by me. It comprises of 2 space blanket along the roof, one pulled closed from each end, suspended on wire runners and attached simply with duct tape for reinforcement and cable ties. Pull it closed as the sun sets and low and behold the heat does stay in, without the heater on, it was 34 F outside at 5.30am and inside was 50 F on the first night. Last night is was 47 F outside and 58 F inside. So it does actually work and is a cheap way to keep the heat in on a cold night.
