UKKO windows and doors are constructed of vinyl, which is the best overall solution for your windows.

UKKO offers better energy efficiency which helps maintain consistent temperatures inside your home. Vinyl frames have welded corners, which make it air tight and prevent elements such as water and dust from leaking into your home. Vinyl offers the best protection against air and noise infiltration, which means a more comfortable and peaceful living environment. Vinyl maintains its new look over time, eliminating fading and repainting.

We offer a 15 years warranty on workmanship 20 years warranty on sealed glazing units and a lifetime warranty on windows.

UKKO has qualified dealers to get the job done right, regardless of the project size.

Most of our products are available in white, cream, brown and custom colors.

Absolutely, UKKO can manufacture window and door units based on your specifications in order to meet your criteria.

Your choice of framing material goes a long way toward determining the longevity and energy of the total window system. Wood windows possess excellent thermal qualities but are prone to deterioration and require painting at regular intervals. Aluminum windows are very durable but offer little insulating value because they conduct energy rapidly. Vinyl windows are your best choice because they offer thermal characteristics similar to wood are extremely durable and provide a finish that is virtually maintenance -free. Keep in mind though, that the best performing vinyl window systems have multi-chambered frames with welded corners.

Argon is a safe colorless, odorless, non-toxic, non-flammable insert gas. It is used to reduce heat loss in sealed units by slowing down convection in the air space. Commonly it is used in place of air between the glass panes of an insulated Low E glass unit. Argon’s heat conductivity is lower than that of air. And thus it is better insulator and contributes to a lower U-factor. Argon is not an effective solar performer by itself and so; it is used on conjunction with Low E insulated glass. Argon gas is a relatively inexpensive option, and can easily recover its cost in heat savings.

The INEX warm edge spacer is the best performing solution on the market. INEX spacer has a conductivity rate 25 times lower than aluminum spacers. INEX helps to reduce your condensation problems, and also reduces the risk of thermal breakage. When you are planning to construct or renovate, demand the INEX Spacer for your windows and doors and assure your self-comfortable viewing throughout the seasons.

The U-factor or U-value is the measure of a window’s thermal efficiency, based on its resistance to the flow of energy. The lower the U-factor, the more thermally efficient the window. Most new window technology had been aimed at lowering U-factors through the use of three important innovations: INEX spacer, low emissivity glass coatings and argon gas

Low emissivity glass, commonly referred to, as Low E. is glass that has been coated with a micro-thin metallic film to improve thermal performance. The coating reduces the transfer of heat rays through the glass while still allowing light to pass through. In essence, the coating reflects heat back toward its source. Thus, heat from the furnace stays inside the home during cold weather, resulting in greater comfort and lower energy costs. Low E coatings also reduce harmful ultraviolet rays that cause drapes and upholstery to fade.
