Again, the total removability of a new style casement window has big part to play
. First, because these new look replacement casements can be fully taken out, they have extra insulation and a high standard of finishing ensuring no air can get in. And second, should the new casement windows ever start to evince a problem with insulation; they can simply be whipped out while the seals are replaced which saves as much time and money as installing them in the first place.
