Wood – How to prevent wood from warping

woodwooden-furniture

I have an electricity inspection box inside the house. What I'd like to do is build a small wooden cabinet to enclose it (it is flush to the wall). I've measured up and bought five pieces of wood:

. 2 x 45mm x 15mm x 700mm

. 2 x 45mm x 15mm x 800mm

. 1 x 15mm x 700mm x 800mm

My intention is to surround it with the thin pieces and use the fifth piece as a door. However, the thin piece have already started to warp (I've had the wood for around a month). Is there any way to prevent this, or does anyone have any tips for doing a similar thing?

Pine that thin is going to warp; if you're going to paint it, I'd use MDF. If you want a natural wood look, a plywood with a finish-grade top layer would be much more stable.
