I will be installing 2 twin awning windows in high shed dormers for a client and they would like to be able to open them from below with a remote or wall mounted button/switch.  The windows will be aluminum clad Peachtree and they don’t offer this kind of mechanism.  Does anyone?  Is there an after market alternative?  I know Velux makes electrical venting skylights/roof windows but I don’t believe would serve our purpose.  If I invented an aftermarket version that fit most brands of windows could I get rich like a rock star?
