Many people find bamboo flooring very attractive. It looks similar to regular wood flooring, but it is harder and more durable. Bamboo has a short growing time, so it is a rapidly renewable resource. Most bamboo flooring contains trace amounts of formaldehyde; one brand that does not is Bamboo Hardwoods, and Teragren contains very low levels.
Buy a pane of glass that is 1/16 in (1.55mm) smaller that the window opening on all sides. Chip out any old putty. Clean out the recess, and paint it with primer. Lay a bed of fresh putty in the rabbet in the window frame. Press the new piece of glass into position around the edges – not in the center, where it could break. Insert glazing brads or clips to keep the pane of glass in place.
