In fall of 2010 Midwest Construction installed EcoSmart casement and awning vinyl replacement windows. These homeowners had 8 years to live with the new windows; they had 8 years of a comfortable home, energy and maintenance savings.

You can't find a better casement or awning windows out there. These are excellent for views above the kitchen sinks.They easily open outward and close tightly with folded operating handles that never interfere with shades or blinds. A great choice for contemporary and traditional homes alike.

The EcoSmart windows are made of UI PVC Vinyl with fusion pinch welder master and sash frames that completely eliminates any expansion or contraction.

EcoSmart windows come standard with our patented insulation in all primary frame and sash cavities. This high density insulation provides a NFRC determined R-Value of 7.25 per inch* of thickness. SmartCore insulation provides almost two times the insulating proprieties of typical fiberglass insulation, making EcoSmart windows more energy efficient and your home more comfortable.  




Another standard feature of the EcoSmart window is the I-Beam & Rigid Core Fiberbar Reinforcement, providing strength to keep your windows performing like new for a house time. Our double hung and sliding windows feature RigidCore at the meeting rails for unsurpassed strength, durability and extra protection from forced entry.

Multi-Point Locking System:

Our easy-to-reach multi-point locking system, with up to four points of locking per sash, provides unmatched performance and maximum security at the most crucial points* using a single locking handle!


Handle and Locks:

Both casement and awning windows come standard with unique folding nested operator handles and matching locks. Choose from multiple hardware finishes for a sleek look.

Weatherstripping:

Continuous triple weather stripping on each sash ensures a weather-tight seal to keep your home comfortable year round.


These are just a few features these homeowners liked, but one of the best features of doing business with Midwest Construction and EcoSmart windows from Plygem is the Lifetime warranty on the entire window including an unprecedented Lifetime seal failure and glass breakage warranty.
