Window Quilt Insulated Shades Keep Your Home More Comfortable All Year Long
Window Quilt’s four way seal stops all air passing through leaky or ill-fitting windows. Dramatically cutting airflow around the shade’s sides while pressure seals close off the top and bottom is vitally important in blocking infiltration of warm or cold air. Window Quilt insulating shades are simply the most effective product available.
- Side tracks eliminate air infiltration and drafts
- Retains inside heat in winter
- Blocks 99% of solar radiation and resulting heat gain in summer
- Eliminates window condensation
- Independently certified efficiency
- Cuts outside noise by one third
- Lower heating and cooling costs!
Stay warmer in the winter
During the colder months, warm air inside the house can be lost through the window opening. Window Quilt blocks this energy from escaping, keeping the warmth inside.
Stay cooler in the summer with Window Quilt
This is what is known as solar heat gain, in the warmer months, solar radiation is the main contributor to warming your house. Window Quilts block this energy from entering in the summer, reducing cooling costs during the season in which energy usage is traditionally at its highest.
Available in light-filtering and room-darkening.
How Does Window Quilt Insulate Your Windows?
Window Quilts addresses all 4 factors relating to heat loss through windows and room comfort: conduction, convection, infiltration, and radiant heat loss.
Complete system for stopping heat loss (or gain) at windows
- 5 layered composite insulating shade material
- Side tracks to eliminate air infiltration
- Top roller seal
- Bottom rail with weatherstripping
Heat loss at windows via conduction
Even though most homes today have double pane windows, many with low-e glazing, glass is an excellent conductor of heat, which is why windows feel much colder than your walls in winter. Window Quilts 5-layer barrier stops conduction at the window surface.
Heat loss at windows via convection
Because warm air rises and cold air falls, windows, especially those with conventional window treatments, can actually set up a flow of cold air in your room. Window Quilt blocks these drafts completely, because it seals the window on all four sides and contains an airtight inner layer.
Heat loss at windows via infiltration
Window Quilt features a four-way seal, stopping all air passing through leaky or ill-fitting windows.
Heat loss at windows via radiation
Warm air moves toward cold air, and in this way, cold windows draw heat from the room's interior in the winter. In the summer, solar radiation is the main contributor to warming your home. Window Quilt blocks this energy from escaping in the winter and entering in the summer, reducing the energy needed from a heating or cooling system to keep the home's interior comfortable.
How Effective is Window Quilt?
Window Quilt publishes the R-value and Air Infiltration values of the product as installed on a test window as determined by an independent laboratory using standardized test methods. Many manufacturers list only the R-value of the fabric itself, and without Window Quilt's 4-sided seal, the effective R-value will be much less than that of the insulating fabric.
