Sliding doors of different sizes and materials including aluminum, fiberglass, and composite are common and so popular for main entrance and patio among both distributors and customers worldwide.
Many clients and builders would rather prefer to utilize sliding doors over conventional hinged doors in order to provide a more modern view for their buildings.
As you may have seen, most people believe that a balcony or a patio looks bigger and more beautiful when sealed up with a 90%glass sliding door, because it gives a bigger picture of the sight out there.
The other advantage these sliding doors provide is that the big glass flat they are consisted of, lets a bigger amount of sunlight inside the house and this is of the essence for most housewives, especially in cloudy cities.
Though builders and families go for purchasing sliding doors of all kinds such as aluminum, fiberglass, and composite, for two main characteristics: first, sliding patio doors have to be weather-proofing. 
People in various countries may experience several changes in climate in a year, though, the glass utilized for the production of these doors has to be resistant to both very cold and very hot weather.
Second, they have to observe energy efficiency which addresses the protection the sliding glass door provides for the heat inside the room in cold seasons of the year.
The other feature which deserves to be put into consideration is the quality of the rails letting each door slide; they have to be smooth enough.
Manufacturers have also produced other types of sliding doors such as vinyl and wood.
Aluminum Sliding Glass Doors
Aluminum as one of the lightest metals in the world is a popular raw material for glass door manufacturers to use in the production line of sliding doors.
A super light metal like aluminum is suitable for manufacturing doors due to a handful of main reasons: first, a door made of aluminum is easy to open and close even for children.
Second, it is solid and durable enough, especially for families with more than two children, and governmental and administrative buildings with lots of visitors.
It neither loses its glaze nor erodes.
And third, aluminum is cheap.
Most of the aluminum doors manufactured by various companies in different countries must have characteristics like they have to be slim (20 millimeters up to 25 millimeters thick at most) and the standard glazing layer covering an aluminum framework has to be 30 millimeters up to 45 millimeters thick.
Acoustic and thermal performance is of the essence, too.
Even though the body and the framework of the door are of aluminum, the rail must be of stainless steel for convenient sliding. 
There are also aluminum classic-like models in different colors designed for the customers who prefer nostalgic sensation over modernity.
These models suit traditional brick buildings and mansions best.
The remarkable point about the latter is that they are still weather-resistant, energy-efficient, durable, and acoustic as well as super slim.
That’s why aluminum has always been a trustworthy and reliable raw material; a metal for all functions.
Fiberglass Patio Doors
As light and financially efficient alternative raw material instead of aluminum, some companies have begun utilizing fiberglass for the production of patio doors for both houses and administrative buildings.
Fiberglass, a very strong material _even stronger than aluminum itself_ is extremely weather resistant and can be the best choice for people living near coasts, high wind areas, and regions with salt air.
The Humid weather of coasts contains enough nitrate to ruin all kinds of metal but not fiberglass.
The staff is also more energy-efficient than aluminum and keeps more heat for a longer time.
Though, fiberglass can be a proper choice for anyone living anywhere.
Fine fiberglass which is produced of glass wool as the reinforcing material and polymers as base material mixed together, is the fundamental ingredient for the production of acid tanks, cement silos, and car bumpers; being consumed for the mentioned, is per se a solid proof, demonstrating how strong and useful material fiberglass is. 
This strength makes it possible for the manufacturer to allocate a vaster proportion to glass which leads to a house with more sunlight.
Moreover, the tight seal these fiberglass doors have doesn’t let the air, the dust, unwanted irritating noises and smells inside the room, and also fog between glass layers.
Other materials such as vinyl may give you not more than a few models and colors; this makes the homeowner adapt to the decorative circumstance instead of changing it for good; but fiberglass sliding doors give you a wide range of options, like French styles.
Composite Sliding Patio Doors
What has made composite a popular and vital material in the production line of sliding doors and specifically the ones used for patios is that it is very nature-friendly, flexible, and strong.
Before we get more acquainted with composite sliding doors, we have to know a bit more about the material itself.
Wood composite which we are discussing is a mixture of wood and polyethylene, wood and polypropylene, or wood and polyolefin.
But most of the customers would rather prefer the mixture of wood and PVC; one of the reasons for this is that PVC is less incendiary than any other similar material.
Wood composite (WPC) is nature-friendly because of having recycled thermoplastics and farms residuary such as grains’ stems and sugar cane waste among its ingredients, but note that micro-organisms are definitely not part of the plan.
Production of this material has not only cut the dependence to woodcutting but has also founded a vast and long-lasting field of investment. 
Another specification of it is its efficiency for being produced and its raw materials are easy to find.
Composite is as good to be used for making mobile homes, fences, and urban benches.
Composite doors are good for a handful of reasons: first, they are resistant to moisture and the troubles it makes including decay and physical damage.
The structure of composite doors is the way it can host all types of designs and colors to suit your house best; finally, it is energy-efficient and lowers the costs of heating and cooling.
