NT Window Super Spacer® for Superior Energy Efficiency

Super Spacer features one of the most effective Argon-resistant bonding adhesives, which helps retain gases within your window for an extended period. This strong bond leads to reduced U-Values and increased energy efficiency. Additionally, Super Spacer is metal-free, resulting in lower energy conduction and improving the edge temperature of the glass by up to 16.6°F compared to other spacer systems.

Which Window Style Is Best For You?

When choosing the style of windows for your space, you should consider more than appearance alone. Each window style has its own unique attributes and, therefore, should be used for particular applications.

  • Single-Hung

    Single and double-hung windows look very similar. However, in a single-hung window, only the bottom sash (glass pane) opens.

    ● Cost effective
    ● Safe
    ● Easy to operate

  • Double-Hung

    Some people appreciate the versatility of a double-hung window in which both the bottom and top sash open.

    ● Flexible
    ● Maximum air flow
    ● Easy to clean

  • Picture

    A picture window does not open and does not typically have a grid to interfere with the view of the outdoors.

    ● Unencumbered views
    ● No maintenance
    ● Modern aesthetic

  • Sliding

    A sliding window is a great choice for a wide window opening. Like picture windows, sliding windows do not often have grids.

    ● Cost effective
    ● Low maintenance
    ● Easy to open
