Energy Pro® Windows
The Solution for Energy
Efficient Homes
Energy-Efficient Windows Designed for Maximum Performance
Each JKR window is built with tested and proven materials to enhance efficiency and lower energy costs.

- ClimaTech glass minimizes heat flow, reducing reliance on air conditioning and heating.
- Triple-pane ClimaTech windows are more energy-efficient than traditional windows, acting as a thermal barrier.
Plus, our Energy Pro® windows come in a variety of colors to complement your home’s style, with decorative grid patterns and cut glass options for a unique, polished look.

- Visually clean and contemporary narrowline frame and sashes, with a larger glass area for exceptional daylighting and outside viewing.
- Internal chambers meticulously engineered for structural integrity and enhanced energy efficiency.
- Low-profile secure locking hardware features an indicator that tells you if your windows are left unlocked.
- End-of-throw cam shaft locking action, expertly constructed for increased protection.
- Composite reinforcement in the meeting rails allows for secure mounting of hardware; this nonconductive material also reduces the transfer of energy for superior thermal performance.
- Super Spacer System with a structural foam design helps the edge of the glass for superior thermal performance and longevity.
