OKNA Insul-Tec Replacement Windows (500 Series)

When you consider to start a window project and you shop around. One of a good choices might be OKNA Insul-Tec Replacement windows (500 Series).
This vinyl window looks stylish and appealing.

As always we are gonna look at three most important characteristics of the window:
—Beauty
— Reliability, Performance and Warranty

Beauty

The window frame and sashes are made from virgin vinyl. When you look at the window, you can see pure white color. When bluish color is present, it means that the window is made from recycled vinyl.

The window has balance covers. Some other window manufacturers neglect that one small detail. After some time spider web and dust accumulates inside the balance channel and it is not easy to clean it

The window has low recessed sash lock. The design of the lock makes the replacement window look more stylish and modern

The combined sash and the frame thickness is acceptable. This window can be installed into the house with small windows without a glass area loss.

The Exterior of the window has a rounded beautiful screen channel. It gives a wood window look for the window.

Reliability, Performance  and Warranty

• Okna Insul-Tec Windows have Block and Tackle Balance System.  It is low maintenance and durable. The window can be opened and closed for about 28,000 time, before the balance system fails.
• The window has triple layer of weather stripping on both sashes. There is an air bulb on the top sash meeting rail. When you close this window, there is no chance that any air is going to get into the house or out of the house without your permission
• This window has thick air bulb on the bottom sash. That makes the window sash shut like a door of a fridge.
• Okna Insul-Tec does not have weep holes. The window has a fusion welded sloped sill, so all the water drains from the sill to the outside. The weep holes get clogged with spider web and dirt. If that happens the water stays inside the frame of a window and may get inside the house.
• Well made night latches are standard. It is a nice feature to have in a vinyl window especially when you have pets or kids in a house. You can lock the window sash with a 3” opening space.
• The window has Lifetime Limited Warranty. It covers all the locks and moving parts of the window for as long as you own the house. The glass of the window has a lifetime coverage as well.

The Screen frame of the window is made from a rolled formed aluminum, which is not that durable 

What could be done better in that replacement  window

    So the OKNA Insul-Tec Window (500 Series ) has 11 stars minus one star, the total comes to 10 stars. It is pretty much a durable and stylish window, worthy of consideration
