Okna precision-weld Replacement windows
When it comes to windows selection, we have a wide choice of manufacturers. OKNA Precision-Weld Series is the product of OKNA Windows And Doors Company.
This type of the window is one of the most popular products offered by the company. The other name that these replacement windows go is OKNA 400 Series. So let’s see why some people say it is the “future today” windows.
Beauty of The Window
The Interior of the window makes it look like the part of the room. The frame of the Precision-Weld replacement window has rounded edges and gives richer look to the interior of the room.
The frame has balance covers, that gives to the window a finished look and prevents dust and spider web build up in balance channels. Night latches are standard as well, so you can vent several inches of the top or the bottom of the window. The OKNA 400 Series have a slim profile sash lock, but you have an option to add Auto-Lock feature.
The thickness of the frame and sash combined is 3’’, which is a bit on the bigger side, especially if you have small windows. If your windows are bigger, then you are not gonna notice the loss of some of the glass area.
The Exterior of The OKNA 400 Window has a modern look. The screen channel of the window has curved edges, which gives to the window pretty much a unique look. Most of the window industry uses square strict edges, which makes the window look a bit colder and boring.
Performance of the Window
Precision-Weld Series double hung replacement window boasts with very impressive energy efficiency ratings. The U-Factor of the window with the basic package is 0.28, the SHGC is 0.30. You can see on the pictures the thick double layer of weather stripping on both sashes and air bulb on the bottom sash.
The air infiltration rating is 0.05, which means the window closes tight as the door of a fridge. The special bulb between the top and bottom sashes adds to that great air infiltration rating. Most of the air comes from that spot. Other manufacturers neglect to insulate well that important part of the window.
The engine of the window is block and tackle balance system and can achieve about 28,000 cycles, so you can open and close your window about so many times, before the engine is gonna blow up so to say.
OKNA Precision-Weld windows come with standard half screen or can be upgraded to full screen option. The screen is made from extruded aluminum, which adds to durability of the screen. The screen does not not have locking mechanism, but there is an option to add that feature.
Quality of the Window
The window frame is made from the virgin vinyl. It means that the vinyl used in the window was not remelted from other vinyl products. Block and Tackle balance system is maintenance free and does not need lubrication. Both the frame and sashes are fusion welded for extra durability. High performance HeatSeal Spacer is used in glass pane system and prevents any moisture to accumulate between the two glass panes.
