Originally, patio doors were all of the French Door variety; that is, a pair of doors that are hinged at the sides and open from the middle, each door pivoting in- or out-wards. French doors are still popular, especially with builders of new homes, as they are comparatively cheap and easy to accommodate in place of windows and offer an alternative evacuation route for families, especially for elderly or disabled people, to meet improved fire safety requirements.
Screen doors are the other option, as previously stated that can also add a rustic look to a patio. Screen doors work best for resort style homes, log cabins, and in places where the weather is generally hotter longer. A screen door is much cheaper than their metal and glass counterparts and is usually made of wood and screening. Metal screen doors will cost a little more but last longer against the elements. In choosing the correct set of patio doors for under $1000, people have a wide variety to choose from if they are willing to install them without professional help. Even so it would be hard to break the $1000 barrier unless there is a multitude of doors that need replacing. Choose the style that best fits the theme of the home and enjoy a bug free patio area for years to come.
Metal frames, usually aluminium, provide strength in compact form. As notoriously good conductors (which is a bad attribute for insulation), frames made from aluminium are thermally-broken, which is a good attribute. It means that the metals on the inside and outside of the door frames are not joined, preventing the temperatures from being transferred between them. A bare metal frame would look completely unattractive so it is powder-coated in a choice of over 100 standard colours, including a white that resembles pvc.
While sliding, folding or standard push-pull doors are part of style, they are given much important because they also have a lot to do with space. Sliding and folding patio doors are more preferred since they can give you more house space. Not only that, but a patio door that folds can also lead to a wide open patio that can make the sun shine in your home. Deciding on the type of opening for your door is based on your general preference; be informed though that there are many options to choose from.
In the mid-20th century, sliding doors became very popular - two or three panels of glass that slide along grooves in the floor. To distinguish them from traditional French doors, they were marketed with the thoroughly modern name of Patio Doors and this is often the image people have today when that term is used. Easily installed in place of a window, the immediate advantages were additional natural light and access to the garden. They also became a popular option to use where a pivot door opening space was limited or where the aperture was wider than a pair of French doors. Older installations were typically single-glazed, prone to warping and usually became difficult to slide open and closed. Still available today but in a developed form with double glazing and rollers for easier sliding, the popularity of sliding doors during this century has declined as bifolding doors gained market share.
Sight lines is the term used to describe the interruptions in the view through the doors; in other words, the width of the vertical opaque areas between the glass when the doors are closed. On hinged doors, such as French doors and bi folding doors, timber and pvc frames generally have broad sight lines because, unlike aluminium, narrower frames would not be strong enough to be fit for purpose. As a guide to the width of two frames together, cheaper pvc door frames can exceed 200mm, aluminium frames are typically between 135mm and 160mm and frameless patio doors sight lines are under 40mm. Depending on the width of each door and number of doors to be installed, the difference in glass to frame ratio could be significant.
