HiMark 400 Windows Reviews

The HiMark 400 window series is the entry level vinyl window in this somewhat exclusive line of windows. HiMark is an Okna window series that is sold through a somewhat more exclusive list of dealers, and the installation is done by factory trained installer (and must be installed by these Okna trained teams.)

The 400 series uses a slightly more narrow frame than the upgraded HiMark 500 series, which provides for more glass area, but at the cost of a bit of durability in the extrusion and a slight decrease in the overall energy efficiency of the window. The 400 HiMark has a few other very subtle differences, including weatherstripping and a couple little differences in available components and hardware options.

Consumers can expect good energy efficiency, especially with the DX model; .28 U-value, .30 SHGC and .05 air infiltration. In general, the HiMark 400 window is considered a good quality vinyl window that is on par with many manufacturers mid range to even premium offerings.

The HiMark 400 window with the foam fill insulation, low-e glass and argon fills will deliver the following performance numbers: .28 U-value, .30 SHGC, DP45, .54 VT, and .07 air infiltration.

If you opt for the Deluxe package upgrade, you can expect the the U-factor to low to .22. These are excellent numbers for an "entry level" window, comparable to many other manufacturer's premium vinyl window offerings.
