Review: This is the grand lady of skylights.  In fact, it's more than a skylight, it's a balcony.  We have installed several of these units over the years and nothing else gives the same experience as this balcony skylight does.  It is quite a bit larger than any other skylight system, and requires a fair bit of restructuring of the roof framework. Also, it is the most complex skylight on the market and requires a very experienced crew to install.   This skylight provides such a spectacular atmosphere of a balcony up amongst the tree tops, that it usually becomes a big selling feature for a home.
