What it is

Destiny and NorthWind: which window fits your home?

We carry two Energy Star certified window lines from National Vinyl. Destiny is the premium option: an all-welded frame and sash, Ccore polymer reinforcement, Gold Series triple-finned weather stripping that seals about 25% tighter than a standard fin seal, and a glass breakage warranty no other line offers. NorthWind III is the mid-tier choice: a fusion-welded frame, Energy Star certified, virtually maintenance-free, and backed by a lifetime limited warranty.

Both lines are manufactured by National Vinyl and installed by our team. Energy Star certified glass keeps conditioned air inside and seals out drafts, so rooms stay quieter and more comfortable year-round while reducing UV fading on floors, furniture, and photographs. If you choose Energy Star triple-pane replacement windows, HCP is an Energize CT authorized contractor and can file the $100-per-window Energize CT rebate on your behalf.

What changes

After your windows are installed

Comfort Drafts sealed, rooms quieter

A memory-foam bulb seal at the sash and sill — similar to the gasket on your refrigerator — holds its shape after months of compression, blocking air and water infiltration. Multi-chambered frames and sashes add insulating value. Gold Series triple-finned weather stripping on Destiny seals about 25% tighter than a standard fin seal, which also reduces outside noise.

Efficiency Lower energy bills

Energy Star certified glass reduces heating and cooling loss in every season. R-5 triple-pane glass cuts heat loss 30–40% versus a typical Energy Star window — putting these among fewer than 60 window lines nationwide on the DOE R-5 program. As an Energize CT authorized contractor we file the $100-per-window triple-pane rebate on your behalf.

Protection Lifetime warranty, zero maintenance

Fully transferable lifetime limited warranty covers all structural components (jambs, sashes, balances, casings, sills), movable parts, and glass against seal failure. Destiny adds glass breakage coverage. Virgin vinyl never needs painting or refinishing. Low-E glass reduces UV transmission, protecting floors, furniture, drapes, and photographs from sun fading.

Written by my mother who recently had work done on her house: "I highly recommend HCP! The crew were knowledgeable, and professional from audit to completion of project. They answer any & all questions or concerns. They cleaned all areas worked on leaving my home pristine daily. Customer Service is OUTSTANDING, especially Lucy B. who was so informative & friendly. So impressed with this company, they not only did my insulation but replace my windows as well! Thank you so much Mr. Wyatt for helping me make my home energy - efficient!!!"

Justin and Pete did a comprehensive and detailed energy audit, incorporating a blower test for air infiltration, of our condo in Brookfield CT. As our condo has a number of energy upgrades like new windows, doors, and insulation there were no surprises that came up, which was good news. We were happy with how Justin and Pete explained the test and it’s results.

The crew meticulously went through my home....insulated windows and drafty areas, installed weatherstripping around my door jambs, checked my windows to ensure no air was finding its way in. They provided me with recommendations, such as buying magnetic covers for my a/c vents on the ceiling, covering the a/c return, and buying LED covers for the recessed lighting in my dining room, all as a means to reduce cold air from coming into my house from my attic space. They inspected my home for insulation needs and will be providing me with a quote soon. I highly recommended Home Comfort Practice. Take advantage of the wonderful Energize CT program and get your energy audit scheduled today.
