Question: What are the skylights made of?

Answer: Alpha Systems manufactures both inner and outer dome skylights in both polyethylene and poly-carbonate resins. Polyethylene is a common plastic resin. Polycarbonate resin is very durable and preferred for outer dome skylights that need to last the lifetime of the recreational vehicle or cargo trailer. Poly-carbonate is strong as steel and as clear as glass.

Question: What sizes of skylights does Alpha Systems offer?

Answer: Alpha Systems offers inner and outer domes to fit a standard 14” x 22” opening.

Question: What are the benefits of Alpha Systems’ skylights?

Answer: Alpha Systems’ skylights are made from injection molding, so they are 20% thicker than the rest of the competition skylights, which are vacuum-formed. The skylight nailing flange is 20% thicker than any other competitor skylight. This additional thickness from the injection molded process ensures a flat, properly seated nailing flange, keeping water outside of your RV or cargo trailer. The competition has a wavy, leak-prone nailing flange comprised of flimsy, thin, vacuum-formed plastic.
