Located at 2901 Peach Ridge NW in Grand Rapids, Michigan, the Harbor Window™ showroom features full-size window and door displays located in a relaxed, comfortable atmosphere. Professional window specialists are available to help you choose windows and doors to make the most of your remodeling or new construction project. Our showroom is open to the general public from Monday through Friday 8:00 a.m. to 5 p.m. or by appointment.

Every Harbor Window™ features dual insulated glass units with double-strength Pilkington LOF glass and warm-edge Super Spacer®.

The unique mortise and tendon construction of our tilt-wash double hung and sliding window gives our windows a more attractive appearance and tighter tolerances than almost any other vinyl window on the market. Harbor™ casement and awning windows are completely fusion-welded, offering the most in energy efficiency.
 

Designed to keep your home cooler in hot weather and warmer in cold weather, Pilkington's Energy Advantage Low-E is the clearest Low-E available. It is color neutral, so there's no blue, green or bronze tints to reflect off its surface. And, it performs better than any other Low-E glass in our cold, northern climate.

Tests have proven that Energy Advantage Low-E is the only Low-E glass that will actually outperform an R-19 wall in terms of net heat loss!

Utilizing the Edgetech Super Spacer® all foam design, condensation is virtually eliminated on the Harbor Window™. Warm-edge Super Spacer® is a completely non-metallic spacer, unsurpassed in thermal performance, conducting far less cold than traditional aluminum spacer systems.
 

No window company can claim to be the best if their windows feature anything less than Truth Hardware. Truth Hardware is engineered for durability and years of dependable service and carries a manufacturer's lifetime warranty. Truth's E-Guard coatings are second to none in corrosion resistance. Harbor Window™ double hungs and sliding windows utilize Truth cam-action locks. Our casement windows feature the Truth multi-point locking system and Truth Maxxim crank-out hardware.

Unique spiral balances are standard on the Harbor Window™ tilt-wash double hung. This self-lubricating, torsion spring balance system has no stretch springs to wear out over time. Unique balances feature heavier steel than other spiral balances and are the only balance system backed by a manufacturer's lifetime warranty.

For new construction, pre-applied wood jamb extensions are available in a variety of select solid wood choices including: oak, poplar, maple, pine or custom options.
