>>114664695That was my actual first thought too lol but skylights can be made of different materials. Arnold always seemed like he lived up North so Summer would be the only even warm time of the year.
That being the case you can still go up on the roof and throw a tarp on that glass real easy.
Or get some tinted glass.
Your real issue is gonna be humidity if the seal on those glass panes isn't absolutely perfect.
Especially when Arnold starts bringing girls over.
