Well the house is full of air, a non-metal.....
Explanation:
And the house probably has a wooden framework, and drywalling, non-metals.... The roof is probably ceramic, a non-metal, and the windows are made of glass with wooden sashes, non-metals, and the floors are probably concrete, a non-metal. And houses which use bricks and mortar also use non-metals.
Of course, these days, aluminum is a very common building material, both for sashes and door-frames, and as the studs for inner walls.......
