Our Showroom

It’s impossible to know how a new replacement window is going to operate by looking at a photo in a sales brochure.

Great Lakes Energy Products Inc. has a customer-friendly showroom for customers to try opening, closing and wiping of full-sized models of tilt-in single or double hung and double slider windows, as well as Garden windows and other speciality windows.

There are also patio doors and steel entry doors on display.  Window and door hardware can also be tested for durability, security, and ease of use.

Great Lakes Energy Products Inc. is the exclusive supplier of windows and doors to many large home builders as well as private home owners. We also install replacement windows directly for homeowners.

Owners Brian Rankine and E.J. Pattison invite you to try out the windows and doors on display in his showroom.  “Look at your leisure. Take your time choosing what you want. There’s no pressure here,” says Brian.

Once you’ve decided on the style, Great Lakes will go to your home to take measurements and quote the project. “Let us know when you’re prepared to go ahead,” Brian says. “We’ll be ready when you are.”
