Many things fall under the term "window covering," including drapes, shades, blinds, and shutters. In rural areas, these items are put up for aesthetic purposes and to provide some additional insulation. In Philadelphia, window coverings are installed for these reasons, as well, but they are also necessary to give your home some privacy. In the city, a good window covering system will keep out prying eyes, reduce heat transfer around window frames, and will look good doing it.
Philadelphia Window Coverings for Insulation
In older Philadelphia homes, windows leak a lot of heat into the outside. During the winter, this spells higher energy bills and a less comfortable living environment. To reduce heat loss in your southeastern PA home, a set of heavy draperies or curtains can create a buffer zone of sandwiched air between the window and the rest of the room. While it might not seem like it would make much of a difference, many have found a significant change in how comfortable a room is after installing a few sets of thick curtains. Just remember, to block heat from escaping, the drapes have to be kept closed.
Privacy Window Coverings
To keep the outside world from viewing what's going on inside your house, blinds and shades work pretty well. Though you can certainly have several layers of window coverings (for example, some people have shades, curtains, and exterior shutters on all their windows), a set of insulate vertical blinds can reduce heat transfer, block others from looking in, and, with the pull of a string, slide open and let in the sunshine.
Decorative Window Coverings
In Philadelphia, window coverings don't have to just be about function. Sure, they can reduce heat transfer and create a visual barrier, but that doesn't mean you can't have fun with them! Features like exterior shutter make a house look great and have a traditional Pennsylvania aesthetic. In fact, exterior shutters have become so anchored in decoration rather than function that half of them don't even work and are fixed in place just to look good.
Decorative window coverings can work wonders for a home's interior, as well as heighten its curb appeal. By adding something like wooden or bamboo blinds or floor to ceiling drapes, a room's appearance can be changed dramatically without having to pick up a paint brush or move a single piece of furniture.
Philadelphia Window Covering Professionals
To really make the most of purchasing window coverings, Philadelphia residents might consider hiring a professional interior decorator. It is true that most interior window treatments are designed to be installed by anyone, but with all of the different choices out there, picking the perfect accents for your home can get a little confusing. An interior decorator will be able to work with you to find the best matches for your needs and the look you want, and will also have a good knowledge of what new products are available, what has been done in your area, and what best suits your space and budget. Though hiring an interior designer is not a necessity, many people have found that they are happier with the finished look of a room when it was planned with the help of a little professional advice.
