:wall: My house is older and has aluminum windows, which have the outer screen window that slides up and down, in the aluminum track. Most of them are so hard to slide open and closed, I can hardly ever open my windows when it's nice out. I cannot afford window replacements, so I would like some solutions as to what I can put in the side tracks that will free up the windows. I've tried WD-40, didn't work, and 3-in-one lubricating oil. The oil worked AFTER I was barely able to budge the window up, then squirted it in the tracks, then barely budged it up and down again. But by the next time I tried to open it, it again would barely budge. The tracks and window don't appear to be dirty or obstructed in any way...does someone have some ideas that might work on a continual basis? Thanks!

Has any had the Solatube installed? We are planning on installing 2 solatubes in our screened porch to bring in more light. The porch is on the north side of the house. The direct sunlight on the roof is gone by 3:30 pm. Does anyone know how effective the Solatubes are when there is no direct sunlight? Because the porch has a finished ceiling we're avoiding the basic skylights. I think the channel required to install them will become a bug and spider web collector. I'd appreciate your comments. Thanks
