Warm Window System

The Warm Window fabric consists of four layers of different fabric quilted together in 4"-wide lengthwise channels designed to reduce the flow of energy through your window glass. The layers are:
  • Lining with fabric protector
  • High density needled holo fibers
  • Reflective polyethylene moisture vapor barrier
  • Metallicized Mylar with air-trapping fibers


A decorative fabric of your choice covers the side of your Warm Window shade that faces the room. Choose a cover fabric that is tightly woven, of light to medium weight, and made of cotton or a cotton/polyester blend. Fabrics with fabric protector are an excellent choice for window coverings. Avoid highly textured or pile fabrics and loosely woven or stretch fabrics. You should also avoid fabrics with horizontal stripes as they may interfere visually with the folds in the shade.

The system is complete with a magnetic seal achieved from sewing magnetic strips into the seams of the shade and affixing magnetic tape to the window frame or wall.

How does the system work?


Warm Window insulated shades are carefully engineered to combat all four major causes of heat loss.
  • Conduction is reduced by trapped air spaces between the fibers and layers of insulated fabric.
  • Infiltration is reduced by the impervious polyethylene and tight magnetic edge seal.
  • Convection is reduced by the magnetic edge seal.
  • Radiation is reduced by the reflective Mylar which reflects radiant heat back into your home and also reflects away solar gain in summer.


What is R-Value?



The effectiveness of any material in preventing energy from flowing through it is defined in terms of R-value. The higher the R-value of a given material, the greater its insulating capacity. This chart illustrates some R-value comparisons.

Our insulated Roman shades have a crisp tailored appearance that compliment any decor.  This style shade is flat when lowered and forms pleats when raised.  Any number of variations are possible by combining fabrics, adding borders, or adding a valance. 

See instructions on measuring and picking a decorative cover fabric.

Width x Length in inches Divide by 144

(If you are planning on making a valance or cornice to install over your shade, use stack width to determine the amount your valance must project from the wall. Stack depth indicates the length of your raised shade.)

Measuring

ROMAN SHADES

When measuring your windows, check the measurements width at the top, middle and bottom. For an outside mount, take the largest width. For an inside mount, use the smallest width.

When measuring your windows and considering which mounting option to choose, consider the following:

  • Does your window have decorative trim surrounding it, or no trim at all?
  • Do you wish to conceal the trim around your window or allow it to show when the shade is lowered?
  • Is there a spot on your trim that will accept the magnetic tape?
  • How much space is there above the window for stacking?
  • Are there any light switches or heat vents that could interfere with the shade operation?


If there are multiple windows in a room, how can the shades be mounted to create a consistent appearance from window to window?

DRAPERY DRAW (OUTSIDE MOUNT)

Determine the width of the shade for an outside mount by deciding how far outside the casing you want the shade to be and measure accordingly. If you are considering an outside mount, choose one of the following options:

1. Shade extends to the outer edges of the trim, covering trim completely when closed. Magnetic tape is placed on the outer edges of the trim.

2. Shade stacks beyond door opening, exposing all of the window glass when opened. A mounting board is added to the stationary side of the shade for attaching the magnetic tape.

If you are considering an inside mount, choose one of the following options:

1. Shade fits completely inside door opening. Trim must be added inside door opening for placement of magnetic tape.

2. Shade extends beyond door opening at sides at least 3/4" on each side. Magnetic tape is placed on wall or trim.  

Mounting

Outside mount:

Ideal for most windows. Can be used on windows with trim or without trim. Permits shade to be drawn up completely above window so glass is not obscured when shade is open. Shade must extend beyond window opening a minimum of 5/8" if there is no trim. Mounts to the wall above the window with the mounting board installed flat against the wall.

Inside mount:

Shades fit completely inside window opening. It may be necessary to add 3/4" x 3/4" molding inside the window opening at sides to attach magnetic tape for a complete edge seal. Mounting board installs to inside top of window frame.

Hybrid mount:

Combines features of inside and outside mount. Suitable for windows with or without trim. Mounting board installs to the inside of the window frame. Shade extends beyond window opening a minimum of 5/8" each side.
