It's true, generally speaking, all vinyl windows do look the same from the outside, but if you have the opportunity to see the inside (or a cross section) the story changes dramatically.

When selecting a quality window, it is important to consider the number of hollow chambers, (or cavities) that a window contains.Why is a multiple chambered window a sign of quality and integrity?

A window that incorporates a multi-chambered system increases the total weld surface that is available at each corner of the window. The larger the weld surface, the stronger the corners, and hence the increase in the integrity of the total window fit.

Other benefits of a multi-chambered system include:

  • less distortion in frame and sash materials
  • increased useable living space in your home
  • reduced noise levels from outside your home and the
  • provision for steel reinforcing when necessary

I know we have significantly improved the appearance and value of our home by installing Ostaco windows.

We recently chose to have Ostaco replace our windows. Our house is 10 years old, and the builder grade windows were a constant burden with drafts, leaks, and maintenance. Our windows were replaced in February, and we noticed an immediate difference in how warm the house was. This difference is equally noticeable in the summer. Our air conditioner is not constantly running as it used to, and the house is always comfortable. Ostaco’s windows look great & perform well.
