You may not have notice, but your old fashioned patio door is causing you to spend unnecessary energy. Ordinary glass is a notoriously good thermal conductor. During summer months, it can let heat from the outside to travel inside. And when it is winter, it can easily radiate coldness inside and may cause drafts. More heat or cold inside the home during summer or winter translates into more use of air-conditioning or heating systems. That means more energy use and more carbon emission and more expensive electric bills. But these doors are such an elegant household feature that many home owners before are not worried about spending more money for electricity and more energy that would cause more carbon emissions. Some have advocated the use of tinted patio glass doors. While tinted glass may be a good thermal insulator, it would deprive a home owner the most valued asset of this type of door: visual transparency. A patio door that would not allow a home owner to relax inside his home to get an uninterrupted view of his garden or yard would be just the same as a standard entry door.
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.
Cutting costs for home improvement is at the top of all homeowners lists because it makes the appearance of the house look better, it can increase the property value, and it provides a job to do around the home. Replacing patio doors is one of these projects that can be undertaken when the old ones get too beat up. A good patio door can be bought cheaply and installed at no extra cost by a homeowner. The very first step to getting a new patio is door is measuring the dimensions of the doorway. This will allow any door purchased to fill the space correctly. The price of not having the correct size door include lost time, paying for extra materials, and even energy being lost because of poor insulation qualities. Be sure to get the most accurate measurements and keep them close when purchasing a new door.
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.
An alternative solution is to order patio doors with integral horizontal blinds, factory sealed inside the double-glazing cavity. Proven to be reliable, the blinds can be operated via a magnet system (there is an alternative electronic option) that enables the slats to be easily angled to control the amount of light filtering through and can also raise and lower the blinds for maximum light or shade. A major advantage of opting for internally sealed blinds rather than separate blinds is that they are totally maintenance-free - no arduous dusting or cleaning - and because the blinds are encapsulated inside the glazed panels, they are exceptionally difficult to break.
Some manufactures offer optional extras, such as tinted glass, anti-sun, laminated, obscured glass and Argon-filled double-glazing. It is also possible to match existing period features by specifying Georgian bar or leaded-light in rectangular or diamond style. An innovative option is switchable privacy glass which enables molecules inside the double-glazing to become transparent or opaque at the press of a button; this is expensive, though, typically doubling the original price of good quality patio doors.
