Winterizing a Shed Office

With winter approaching, we decided to make our new shed winterized so we can use it as an office.

Please vote for us in the Winterproofing contest!

Step 1: Gather Materials

The shed was basic studs and siding, so we plan to add hard foam insulation and and a plastic seal inside.

We bought the following materials:

- 1 inch foam insulation from the home store in 4' x 8' sheets.

- 100 feet of white tablecloth plastic (since white sheet plastic is hard to find/expensive)

Step 2: Add Foam Panels

We measured between all the studs and cut the foam panels to fit snug.

Pro tip: score the panels with a utility knife then bend and break off for a clean cut.

(Also displayed is our sweet adaptable standing/sitting desk ... but that's not winterizing.)

Step 3: Install Plastic Sheeting

We measured off the plastic tablecloth to fit the space. It took 2 layers to cover the walls,so we put the bottom layer on first so the top overlaps. We used a staplegun to attach to the wall. It's not an airtight seal, but handles drafts well.

Step 4: Project Complete

With the foam panels installed and the plastic sheeting/tablecloths installed, bring on winter!

Step 5: Finishing Touches

A couple more items that make things more comfortable:

- Small space heater

- Foam floor pad to keep those feet nice and toasty (with leftover solid foam).

    Thanks very much. The siding is tan primed fiberboard panels. The siding looked pretty nice the way it came, so I decided not to paint it for now at least.

    Thanks! Being fiber board panels, what R value do they have?

    Thanks again and have Good night.

    Nice work! I need to build a small shed just like that. Was that from a plan, or did you just make it up?

    Thanks for the kind words. I didn't find any existing plans that matched what I needed, because space was limited under my deck. So I copied from a variety of "lean to" shed designs.
