Ostaco Green Patio Doors

Width of the overall glass unit is 1 3/8" top rating in energy efficiency.

The goal for most Canadian families is to keep their house warm in the winter and cool in the summer, while keeping all energy costs as low as possible. With vinyl windows this goal can be reached. Ostaco's specially designed multi chamber vinyl combined with LowE glass create a barrier to heat transfer. Vinyl windows can help lower your costs and increase your energy efficiency.

Vinyl windows are designed and welded to create maximum strength and protection against all weather conditions. Vinyl windows have been tested and proven to outperform aluminum and wood windows, because of their excellent thermal performance of the frame. It's simple, really warm air stays indoors during the winter months and cool air stays indoors in the summer months.
