Question Replacing Basement Windows

Hello everyone,

I'm new to this forum and I plan on helping other as they help me.

Anyway, I purchased seven new Pella sliding basement windows that will be replacing the old steel framed windows that are drafty and hard to open.

Anyway, my question is this. After I remove the old steel frame windows 32 x 14, and make the rough opening 32 x 15, is it necessary to install a wooden frame prior to me installing the window or would it be okay to secure the window itself in both mortar and Topcan screws?

Thank you for your answers.

Yes, the windows should be installed in wood frames. The window manufact-

urers usually call for rough wood opening of 1/2'' larger than actual window

dimensions. The extra space is used to compensate for leveling and squaring

the finished window, plus providing a space to insulate.
