Air Infiltration
The amount of air leaking in and out of a building through cracks in walls,
windows and doors. Windows are tested by independent labs at a 25 MPH force.
The leaking air is measure in cubic feet per minute.
The industry standard is less than .30 or 30% of a cubic foot of air.
ReliaBilt windows can be as low as .08 for our 3900 series windows.
Argon
A gas that is heavier than air and can be used to fill the airspace of an
insulated glass unit. Argon is a safe, colorless, odorless, tasteless, non-
toxic gas, which is six times denser than air. Argon increases the insulating
value of an insulated glass unit as well as improves sound insulation.
Design Pressure
The pressure a product is designed to withstand. This value is a measure of a
product’s capacity to withstand the forces of wind loading, in both positive
and negative directions, while it is closed and locked. The higher the DP
rating the more structurally sound the window will be. ReliaBilt boasts
the industry’s highest rating on any Vinyl Double Hung: DP-60.
ENERGY STAR®
A government-backed program helping businesses and individuals protect the
environment through the use of high-efficiency products. ENERGY STAR®
qualifying products, such as windows and doors, mean these items use less
energy, save money and help protect the environment in the specified region.
Insulated Glass (IG)
A combination of two or more panes of glass hermetically sealed with optimal
air space for energy efficiency. This space may or may not be filled with an
inert gas, such as argon.
Low-E (Emissivity) Glass
Glass treated with a thin transparent coating of metal oxide and silver.
Allows natural light and short-wave heat energy to freely penetrate glass
during the winter while reflecting long-wave heat energy back outside during
the summer months. Keeps your home cool in the summer and warm in the winter.
It reduces the penetration of ultraviolet rays to minimize fading of carpet
and draperies.
R-Value
Resistance to thermal transfer or heat flow. Higher R-Value numbers indicate
greater insulating value. It is the inverse of the U-Value (R=1/U).
U-Value (U-Factor)
The rate of heat transfer through a window or door. The lower the
U-value, the better the insulating properties of the unit or glazing
system.
Weather Stripping
Variously shaped metal, vinyl, plastic or fiber strips that fit tightly
against the window or doorframe to resist air infiltration through cracks.
Wind Load
Force extended on a surface by moving air. ReliaBilt products are the
industries strongest rated in correlation with our High DP ratings. The
higher the wind capacity the stronger the window will be.
Warm Edge Glass
The spacing system between the panes of glass with properties that conduct
less than standard aluminum spacers that touch the glass without a thermal
break.
Manufacturer reserves the right to substitute components as necessary for
continued product improvement.
