Water Tank Storage Shed

The majority of storage sheds are uninsulated and offer little protection from freezing in extreme conditions. If you're looking to locate a water tank in a shed in a cold climate, you'll need to take appropriate measures to avoid headaches down the road ...

Looking at building a storage shed 10' x 10' to hold a water pressure tank fed by my well, for a cabin I have in Colorado. Thought about a shed build from logs, as I went to a log home building class, but foundation costs seem to make that pretty expensive for just a shed. It will need to be very insulated from the cold.

While a log-style storage shed would look great, the insulation provided by the logs would need to be supplemented. Logs have an R-value that falls somewhere between 1 and 1.5 per inch of thickness ... so a 10-inch wide log wall would deliver somewhere between R10 and R15. That might not be enough insulation for an extremely cold climate.

If you want a log cabin look, you could build a conventional or post & beam shed, insulate it with your choice of materials, and use log cabin siding or perhaps wide live edge wood siding. Spray foam insulation along with an exterior layer of insulation board underneath the siding would make for one tight shed.

Tight window and door seals are crucial for eliminating drafts. Any extra effort spent with the caulking gun and weatherstripping tape is time well spent.

Work with the elements, not against them.

You'll likely want the walls of the shed that face the harshest winter wind to be window-free. Adding windows to the south facing wall can add passive solar heat, but the heat lost to any uninsulated glazing can mitigate the solar gain. Choose a roofing material and pitch to deal with the buildup of snow and ice.
