How do vinyl windows compare with windows made from other materials, such as wood and aluminum?
Vinyl windows compare very favorably to those made of other building materials. Vinyl allows for smooth operation year round because of its self lubricating properties and the fact that it does not shrink, swell or bend during harsh weather conditions. The combination of aesthetic appeal, energy efficiency, and low maintenance provides equal or better performance and is often more economical.

Why should I replace my existing windows?
Home-Kim/HK Windows offers many styles to give your home a beautiful new look while improving energy efficiency. They can add value to your home while cutting down your heating and cooling bills.

What are R-values and U-values?
The R-value is the resistance a material has to the flow of heat (the higher the R-value, the greater the resistance).The U-value is the amount of heat that is transferred through a material. (the lower the U-value, the better insulatng quality).

How can I determine the energy efficiency and durability of Home-Kim/HK Windows or any other window?
Two organizations, the American Architectural Manufacturing Association (AAMA) and the National Fenestration Rating Council (NFRC), test the performance and quality standards for windows.

The NFRC established standards for thermal performance.
U-factor: This is a measure of heat loss. The lower the U-factor the better.
SHGC (Solar Heat Gain Coefficient): Once again the lower the better.
VT (Visible Transmittance): The higher the visible transmittance, the more daylight is transmitted. A high VT is desirable to maximize the amount of daylight entering the home.

The AAMA established standards for structural integrity, air infiltration, water infiltration resistance and forced entry resistance.
Structural Integrity is the ability to withstand wind and other dynamic pressures. This is rated in design pressure (DP). The higher a product's rating design pressure, the greater the amount of wind or pressure the window will withstand. Air Infiltration tests involve the equivalent of 25 mph wind. The lower the air infiltration rating the better.
Water Infiltration tests a window's ability to resist water leakage through the window frame, sashes, joints, weather-stripping, etc. No leakage is permitted under this test criteria. Forced entry is tested by a certified lab technician using many different tools to simulate breaking into a home through the window. Next, windows and doors are subjected to hundreds of pounds of force to try to lift or push them open while in the locked position.
Because Home-Kim/HK windows strives to excel in the industry, we built a certified testing facility where the windows are subjected to the strict requirements of the nationally recognized standards.


What is ENERGY STAR and how does a window company qualify for ENERGY STAR compliance?

ENERGY STAR was started by The United States Department of Energy. ENERGY STAR helps businesses and consumers become aware of what products save energy to save money while protecting the environment for future generations. When a product, such as a Home-Kim/HK windows.

What kind of maintenance do my new Home-Kim/HK windows require?
Home-Kim/HK vinyl windows are virtually maintenance free. They are unaffected by moisture, salt air, pollution and airborne chemicals. Vinyl will not pit, peel, flake or corrode making it unnecessary to paint. Cleaning is easy using a simple cloth and mild detergent. Do not use harsh detergents or solvents as these could damage the finish or appearance of the windows.
