NEW CELLULAR COMPOSITE TECHNOLOGY!

Why we distribute and install STARMARK products

STARMARK is manufactured by OKNA windows; they offer a unique window system unlike any other in the industry.

Every material has its limitations. For example; wood is a great insulator but requires lots of maintenance and has some other natural defects. Solid vinyl is a maintenance free product but, does not insulate as well as wood. STARMARK uses a cellular composite frame that has natural insulating abilities.

STARMARKS cellular composite frame system out performs both wood and solid vinyl window systems. Cellular composite windows are much stronger and generate better energy values.

STARMARK window systems are considered the world’s most energy efficient windows with double-hung window U-Factors as low as .24 for double pane and an amazing U-.15 for triple pane.

STARMARK windows has an unbeatable warranty from the manufacturer. Because of their frame construction all hardware is recessed into the frame. They also offer a special triple pane high performance HEATSHIELD glass system, allowing for u-values to be the lowest in the industry. The durability of the frame is un-matched and a good fit for a harsh environment.

STARMARK windows are available in the following systems:

  • Replacement window systems: sometimes called a pocket window (designed to be installed into an existing window frame).

  • New construction system: an applied nail flange so window can be nailed to exterior of home.

Available styles: double hung’s, casements, sliders, awnings, bays and bows.

Special features: exterior colors available, stainable or paintable interior, real SDL grilles (single divided lites).  Also available in a special triple pane HEATSHIELD glass systems making this window system capable of achieving u-values as low as .13.


See the Quality Difference!

Rob, Co-owner of Strong Windows
Strong Windows utilizes only 'best practices' methods in it's installations. Outdated methods using fiberglass insulation around window frames are still prevalent in many companies today, which still allow air leakage and do a poor job of insulating. We at Strong Windows use minimal expanding window & door foam to fill all voids around our windows, and we utilize drip caps integrated into the wall system instead of relying solely on caulking to waterproof the windows.

Our exterior metalwork is custom formed to provide a virtually maintenance-free exterior. Instead of wrapping the exteriors in a flat look which hides architectural detail, we form our metalwork in a number of styles to accent the home.

Strong Windows offers an outstanding service warranty on the windows we sell. *Ask salesman for a copy of the warranty for details.

*Serving Chicago, Chicago Suburbs and Central Illinois.

OKNA WINDOWS
are Super Energy Efficient!

The classically refined lines of the OKNA 800 Series bring to mind a traditional wood window without all the maintenance responsibilities. A streamlined design, packed with a variety of features, make the 800 Series a sophisticated choice.
*
The elegant, beveled profile of our OKNA 800 Series will enhance the beauty of your home's exterior by giving it the traditional look and feel of wood windows with the performance and ease of maintenance you can only get with vinyl. The 800 Series can also be painted to match any exterior.
*
Foam-filled insulated extrusions on ALL OKNA *Deluxe series windows add energy efficiency.
(Insulation type may vary during the manufacturing process)

*
Magnetic Seals (shown in light blue), similar to those used in refrigerators, eliminate drafts and greatly improve the thermal performance of our windows.
