Vinyl construction as used in the Omega 4 series is unique to the sunroom industry. 
Aluminum, which is used in other manufacturer’s sunrooms is among the worst construction materials for energy efficiency. 

Aluminum conducts both heat and cold very rapidly, which is why aluminum is used in cookware. In contrast, Vinyl is among one of the most energy efficient building materials; 1400 times less conductive to heat and cold than aluminum, which means the inside of a vinyl room will be warmer in winter and cooler in summer than aluminum rooms. 

Equally important, the frame components in our vinyl windows and doors contain numerous insulating pockets which helps increase even further the performance of our Omega 4 room over traditional low end 
aluminum sunrooms. 

These insulating pockets also significantly reduce the transmission of outside noises into a Omega 4 room, which in turn improves the ambiance and usability.
