- They can be good second story windows – Both sashes can be tilted from the inside to clean and then tilted back up and snapped back into the frame. This can make cleaning the exterior glass on your second story windows easier in some ways. The only time this doesn’t work is when there are window treatments on the inside that prevent them from tilting in. As far as window treatments, sometimes the bottom sash can clear the treatments but the top one can’t. It just depends on what kind of treatments you have. A single hung can be cleaned on a second story by tilting in the bottom sash or removing it from the frame. Then, pull the screen into the house. A spray bottle and a squeegee while standing inside the home will work from here.
- Double hung windows can reduce light reflecting out onto artificial grass – double hung windows have a screen over the entire window. This does darken the inside of a room a little more than other replacement window configurations, but it also reduces the amount of UV light reflected back out to the yard. Plants and grass are not affected by this UV but some artificial grasses can be affected. It is a shame the artificial grass companies sell products that are may or may not be adequately guaranteed to with stand the normal environment caused by building code requirements for residential housing in the Phoenix area. The windows are required to reflect the UV back out.
- Double hung windows can be lowered from the top. Windows low to the floor with pets in the room can still be opened without the pet being able to tear up the screen to get out. We have also had someone needing double hung windows to keep coyotes from getting in the bottom of the window screens to get at her cats. They are perfect for this scenario but they should never be considered secure from humans getting in when the top is slightly lowered. The only way to lower the top sash is to unlock the window. Both sashes lock together when closed. When you unlock the top to lower it, you have also unlocked the bottom sash for people to open. Windows can only be truly locked when they are closed..
Keep in mind – for all other hung window replacement applications, we do suggest using a single hung window instead, since they are more secure, stable, better sealed, and require less maintenance.
