Summer is high above us and before the scorching rays of the sun reach your windows in full blast mode, now is the time to make those changes in your window treatments that you swore you would do last August. Don’t forget that your bedroom is also angry at those streetlights at night that disturb peaceful sleep. I know our promises are so easily broken and forgotten, but I have a quick refresher course to help you through the maze. So many of you ask me what is the difference between all those terms relating to openness and opacity and room darkening and light filtering….jeez. Yes, there are a lot of factors to consider when light control is at the top of your list when choosing window coverings. Even though I love the sun streaming in the windows, brightening my home and energizing my spirit, but particular windows do have special needs, so here is a simple way to break down these terms.
First, let’s get a major confusion out of the way. The term “openness” only refers to solar screen fabric; hence, solar screen window treatments. If your home is severely sunstruck (large windows, patio doors, skylights, un-shaded windows), and you need to cool down your room, cut glare and protect your furniture and floors, solar screens are an obvious choice. You can select different “openness” levels, depending on how much view, therefore light, you desire. Openness refers to how much light is allowed through the fabric. A smaller openness percentage, 3%- 5%, means less light comes in which equals a darker room, which equals less view. A higher percentage of openness, 5%-20%, will give your room more light, more view, I usually recommend a 5% openness for those who want to see out but screen out some sun and glare. To obtain even more sun with light screening, choose a 10-14% openness factor. Also, note that a plain weave fabric in a darker color will give you a better view than busy patterns which create more obstruction. Lighter colors in a plain weave will reflect the light and add some brightness to the room as darker, plain weave fabrics will absorb some light, creating a slightly darker room. Remember that there is no perfect solution as there is a give and take with view/light and coolness/protection. You need to decide which balance works for you. Caution: solar screens DO NOT provide privacy at night, so you will need an additional window treatment if you don’t like nosey neighbors.
Opacity refers to levels of light filtering for fabrics on Romans, pleated, cellular and roller shades and draperies. Opacity qualities run from very open and light-sheer to semi sheer to light filtering-semi-opaque to opaque (room darkening) to blackout. Let’s review these categories.
These window treatments allow the most light to filter in, but do reduce some glare-little privacy with sheer window treatments. However, the view is maintained and sheers are popular for their softness, grace and casual appeal. Sheer panels or sheer draperies can make your room float, or sheer shades with soft fabric vanes come in different light filtering options to create brightness.
Semi-sheer window treatments diffuse light but still provide little privacy. Semi-sheers are our least popular window treatment and really provide no benefit. You should really clarify your pressing need: view or privacy and go sheer, semi-opaque, or solar to add beauty to function to this in-between need to get the best of both worlds.
Choose a semi-opaque window covering if you know you want privacy and require some bit of light to stream through the window. Your view will be very restricted but your room will not be dark. For the most privacy, choose a double cell, light filtering shade. Pleated, Roman shades and drapery with liners are also good choices here. Semi-opaque window treatments are very popular and versatile with many light filtering choices.
4. Opaque or Room Darkening
Opaque and room darkening are used interchangeably and if you see the description, “room darkening,” be aware that room darkening fabric does not block out ALL light, as light seeps around the gaps, about 1/2″ on each side. For inside mounts, the amount of the gap depends on the type of window treatment you select. Rollers have the most gaps. Romans, pleated and cellulars are more minimal with a 1/4″ gap on each side. To overcome some of the light seepage, go for an outside mount with lots of fabric overlap to “override” the window. Too many of you become disappointed, especially in the bedroom, when you choose room darkening, and the streetlights and car lights annoy you at night. I cannot stress enough that room darkening is NOT a true blackout shade but will considerably darken your room. There, have I stressed that enough?
I am adding blackout as a category for a true blackout shade must have “something” really blocking all light – a mylar interior lining, an acrylic backing with a blackout liner or a 3 ply vinyl material or an extra layer of an additional window darkening treatment. All of these extra blocking materials make these window treatments a real blackout shade that has a thick layer to create a dark and somber room. My favorite is the “Slumber Shade” for you light averse sleepers and vampires who cringe from any brightness.
Many other blackout shades really fail the true blackout test but can still appeal to you.
I know that is a lot to think about now as the sun, heat, light and dark are our friend and enemy. I want you to be able to capture the best qualities so you can harness the light and make it shine or disappear as you choose for your living style.
