Vinyl is a great insulator, superior in its resistance to heat transfer. Dual weather stripping, standard on many of our windows, creates a tight seal, maintaining the efficiency of the window and effectively eliminating drafts
Our many glazing options enable us to produce a window that will provide yearound comfort and energy savings. Dual pane insulated glass, created by sealing two single panes to a spacer, establishing an insulating chamber, is nearly twice as efficient as a single pane of glass at reducing heat loss.
The transparent metallic coating on our optional LoE² (low emissivity) glass filters our solar radiation, thereby reducing heat gain in summer and heat loss in winter, for maximum comfort and energy efficiency.

All of our windows are thoroughly tested for structural and thermal performance, to ensure they hold up under extreme weather conditions. HK Windows are also tested and certified to meet AAMA standards for forced entry resistance, for your protection.

Tilt in sashes allow for safe and easy cleaning from inside the home. Windows open effortlessly, regardless of the temperature or humidity level. A vinyl frame will not rot, chip, crack or peel, and as a result, never needs painting. The frame can be cleaned easily with soap and water when necessary. Balances never need adjusting, so windows operate easily for as long as you own your home.

We offer a choice of solid colors and printed patterns for our vinyl windows. We have several exterior profiles, which enhance the beauty of your home.

We stand behind our windows, backing each one with our Limited Lifetime Warranty. This warranty, which covers the window, the insulated glass, and the window hardware, will bring you peace of mind for as long as you own your home.
