Sun-up Sun-Down Cellular Shades by Graber

Specialities of Day Night Shades

Daylighting is the practice of using the natural light of the sun in our homes, educational institutions, workplaces and even in our malls rather than depending on illuminations using electricity. Not only are we doing our bit in conserving energy, but we are also indirectly maintaining good health, happiness, well-being, and productivity. A bright sunny day is invigorating, such a lot of positive energy radiating in our homes! I may want to try out that new recipe or bake some cookies for the kids, or perhaps sit by my favorite window and complete my embroidery. Cold, rainy days and cloudy skies make me want to curl up in bed and laze around. Did you know that grandmothers still insist that a new born baby be exposed to the daylight to grow faster and that post–operative therapy in hospitals encourages patients to use daylighting to heal faster? IT IS THE SAME WITH OUR WINDOW TREATMENTS. By diffusing and dispersing sunlight deep into our homes, the right choice of window dressings enhances the effects of daylighting reducing the need for an artificial source of lighting.

WHAT ARE CELLULAR SHADES?

Cellular shades are window dressings that aid us with daylighting. They are made up of two or more layers of fabric joined at the pleats to form honeycomb cellular compartments. These three- dimensional “honeycomb” cells trap air that sets them aside from other window treatments. The air present in these cells provides the perfect insulation from the heat and the cold, and when the shades are pulled open they transform harsh sunlight and its glare into soft diffused light for daylighting. The energy conscious call it the highest energy-efficient and sound absorbing window treatment. Most cellular shades are made from a non-woven polyester or of a combination of spun lace and bonded polyester.

SUN-UP – SUN-DOWN CELLULAR SHADES:

The Sun-Up-Sun-Down or Day-Night Cellular Shade is a combination cellular shade. It is also called 2 in 1 shade. This refers to a type of shade that actually incorporates light filtering options into a single shade – a light filtering and a room darkening shade working in tandem with each other. An ordinary cellular shade uses a single head rail attached to the top of the window and a bottom rail to maneuver the shade up and down. The Sun-Up-Sun-Down cellular shade has three rails – a top rail attached to the top of the window, the regular bottom rail, and a middle one that enables Sun-Up-Sun-Down.

These 2 in 1 cellular shades combine a usual blackout or privacy shade with a more translucent light filtering fabric. One type of shade is connected to the top rail and the center rail while the other one is between the center rail and the bottom rail. The center rail then acts as a bottom rail for the first shade and a top rail for the bottom shade.
This type of shade is useful when a light filtering shade should be used for a window at day and a blackout shade at night.

Each panel has its own set of controls so you can expand or contract each one separately on the same track. Although cellular shades are designed to give you the option of having a window that’s all one type of shade, you can also have a portion of your window blocked out by a more opaque cellular shade while the rest is filtering light with the more translucent shade. This combination gives the Sun-Up-Sun-Down shade its versatility. It is ideal for windows that have direct sunlight or one that faces neighbors or the street.

GRABER’S SUN UP SUN DOWN CELLULAR SHADE:

For a Standard Cord Control option of a Graber Sun-Up-Sun-Down Cellular Shade, the right control is the Standard control. It operates the Bottom rail. The Bottom rail coordinates with the bottom fabric. The Headrail coordinates with the top fabric (light filtering). The left control operates the intermediate mid rail. The midrail contains a cord device that controls the Sun-Up-Sun-Down mechanism of the shade. The color of the midrail is made to match the headrail by default, and can be made to match the bottom rail at the time of order. The fabric of the Cellular Shades can be combined in 2 ways. A 3/8” (1 cm) size Single cell can be combined with a 3/8” (1cm) size cell fabric. A ¾” cell size (1.9m) Single cannot be combined with a 3/8” (1.0cm) Single cell or Double cell fabric. Another special requirement is the combination of Cocoon Double cell fabric with another fabric can be possible only if the Cocoon Double cell fabric is the Top of the two fabrics. It is also available as multiple shades on one headrail with a standard gap of ½ “(3cm). Side mounts are available for the total blockage of light. A Single shade has a width of 60” (152.4cm). Multiple shades on one headrail have a width of 42” (106.7cm)

Graber offers a Sun-Up-Sun-Down Cordless lift too. The Cordless Lift option is a safer alternative to the Cord Control Option. Easily accessible cords that are traditionally used to operate window coverings are a safety hazard for children and pets. To avoid any accidents of strangulation, The Cordless Option is ideal for homes with children and pets. Handles are used to operate the shade. Both handles on the Bottom rail or midrail should be used to raise and lower the shade. Side mounts are not available with multiple shades on one headrail. Sky poles are not recommended to operate skylight shades. If required two sky poles should be ordered for an even operation of the shade. The clutch mechanism is in the color coordinated aluminum headrail, and it assists in raising and lowering the shade. It stops the shade at any point and holds the bottom rail level.

Graber’s Cocoon fabric is constructed with three layers made up of 100% metallized polyester film sealed between two layers of soft, high quality 100% Sun lace fabric. This unique design forms a thick barrier of insulation. Independent test proves that Cocoon 3/8” (1.0cm) Double cell fabric is one of the most energy efficient fabrics on the market. Cocoon 3/8” 1.0cm) Double cell delivers a 22% reduction in heat transfer during winter. Cocoon (3/4” (1.0cm) Double cell delivers a 56% reduction in heat transfer during the summer.

SHGC (Standard Heat Gain Coefficient)

The SHGC value of Cocoon 3/8” (1.0 cm) Double Cell is 0.12. SHGC measures how well window coverings block heat from the sun from flowing to the interior. SHGC is expressed as a number between 0 and 1. The lower the SHGC, the better it is for blocking the unwanted heat gain.

UPF Rating (Ultra violet Protection Factor)

Graber Cellular Shades effectively block ultraviolet (UV) rays. Over exposure to Sun’s rays can damage furnishings, wood floors, draperies, carpeting, and artwork. The UPF rating system measures the UV protection provided by a 3/8” (1.0cm) Double Cell Cocoon, Elegant, Neutrals, Facets, Garden Retreat, Translucence as 50 with 99% UV Blockage. The UPF Rating System measures UV protection, both UVA and UVB provided by a fabric. UPF ratings range from 15 (good) to 50+ (excellent). Shade with a UPF of 50 blocks 99% of UV radiation.
UV-Blocking shows window coverings effectiveness at preventing UV rays from entering an interior. The % rating indicates the amount of UV rays blocked by the shade.

THE ADVANTAGES OVER DUAL ROLL SHADES:

The Sun-Up-Sun-Down Cellular Shade or Day-Night Cellular Shades has all the inherent features of a cellular shade, besides the added benefit of being able to control the light entering our windows and controlling our level of privacy at any time of the day or night.
The Dual Roller shades have two separate rollers of the light filtering fabric and the room darkening fabric. This makes the headrail bulkier and heavier than the head rail of Sun-Up-Sun-Down shade in which the pleats of the fabric stack neatly at the head rail or bottom rail without taking up much space and seem to completely disappear.
Cellular shades once raised or lowered remain in that position or stay in one place when released. They are more flexible and versatile for controlling our privacy while Roller shades either stay completely raised or completely lowered and offer lesser options of light and privacy.

The Sun-Up-Sun-Down Cellular shades require little maintenance compared to the dual roller shades. The fabric of cellular shades is less porous. Particulates remain on the surface and can be easily removed either by light dusting or by using a vacuum cleaner. However, the delicate nature of the fabric does not permit their use in areas of a home that have a lot of activity like kitchens and bathrooms.

The energy efficiency of Sun-Up-Sun-Down shade is greater than that of a dual roller shade. The honeycomb design of the Cellular shades makes them the most energy efficient shades. The air trapped in the cells creates an insulating layered air space. This keeps rooms warmer in winter and cooler in summer. They can effectively control room temperature and reduce the use of mechanical cooling and heating, conserve electrical energy and saving money on our electricity bills. The air cavities in the honeycomb structure slow down the transfer of sunlight and radiant heat gain and loss and air flow. The R-value of a window can increase from 3.5 to nearly7 simply by adding a honeycomb shade. R-value is the shades ability to block out temperature differences. A higher value indicates a better insulating shade. The Dual roller shade does this job of insulation too but not as efficiently as a Sun-Up-Sun-Down shade. They offer modest energy benefits by providing a small amount of insulation (lesser than fabric curtains) trapping air and blocking light.

The Sun-Up-Sun-Down Cellular shades are excellent sound absorbers again attributed to the air presence in the hexagonal cells. By absorbing sounds, they can make the surroundings quieter and more comfortable even reducing the noise level in rooms with hard floors. Graber Cellular Shades like the Elegant Neutral, Facets, Garden Retreat, Sala 3/8(1.0cm) Double cell has a sound absorption of 0.60. The Noise Reduction Coefficient represents the amount of sound absorbed by the shade. An NRC of 0 indicates perfect reflection, an NRC of 1 indicates perfect absorption.

The price factor is to the advantage of a roller shade. The nature of the fabric of a cellular shade makes them more expensive than roller shades. If a cellular shade needs to be custom made to fit an unusual window, for example, be prepared to pay twice as much as what standard, readymade shades cost in retail stores. For specific room darkening shades, which can block out sunlight and keep the room cooler, in hot climates, manufacturers tend to charge more. Finally, the type of cord used for cellular shades will influence the price as well. Corded cellular shades are cheaper than cordless cellular shades. A dual roller shade is more affordable because it is reasonably priced and suitable for most budgets.

The Sun-Up-Sun-Down cellular shades are easy to install. The job is relatively straightforward and requires no unusual equipment or tools. Before installation, it is important to know whether the shades need to be mounted outside the frame or inside of it because that information will reflect the sizing. Hiring a professional will be an additional option but an added expense to the homeowner.
If darkness is desired, the SunUp/SunDown cellular shades are an excellent option. Not only do they offer many blackout choices, but their honeycomb construction eliminates the need for visible holes to accommodate the pull cords of traditional shades and blinds. This eliminates those pesky rays of light from creeping into the room when you are trying to sleep. Some honeycomb shades are available with side tracks, which reduce gaps on the side of windows to optimum the choice for viewing in a home theater.

Pairing of fabrics of different style, color and privacy creates a perfect combination, the SUN-UP-SUN-DOWN cellular shades.
