Secrets to buy aluminum sliding/gliding windows. Aluminum opening systems made to fit different building designs, therefore the alternatives are wide, there are many choices and cases. Different products may look similar, but quality could totally different according to system specification. This article discuss aluminum sliding systems’ specification in FAQs type to get understanding of aluminum sliding system and how to check quality.
How to select Aluminum Sliding Window?
The aluminum material is formed into profiles to complete aluminum systems for openings. Aluminum does not affected from natural factors like sun and humidity, therefore aluminum systems customized to prevent water and wind leakage. Another benefit to choose aluminum because it easy to customize and install aluminum opening, compared to wood, steel.The beauty of the aluminum appears in its straightness profiles and the wide variety of paint options either by color or texture.
Aluminum is alloy contain several materials, the difference of material percentage and manufacturer process result several aluminum types. Alloy systems are classified by a number system (ANSI) or by names indicating their main alloying constituents (DIN and ISO). Selecting the right alloy type for a given application entails considerations of its tensile strength, density, formability, weldability, and corrosion resistance. You can test a sample in lab to ensure the quality of aluminum alloy.
Yes Aluminum is waterproof, but the aluminum sliding windows is not aluminum only. Window contain other materials like glass, sealers. Installing methods is an important issue, selecting the right aluminum profiles,the place of holes and accessories are taken into consideration.

Yes, Since sliding window has a roller and rail at the bottom means there is an empty place, that allow water to enter indoors. This requires a small holes toward outdoor to allow water to slide away. Wind direction may not allow collected water to slide away, therefore it requires accessories that allow water to slide out. In the case of heavy rain, small openings can not get water out at the required speed, which may leak rain inside. As a solution for that aluminum companies develop a lower profile that have container underneath the rollers rail to accommodate the largest amount of water away from the roller rail.
Another thing to take into consideration that low thickness of aluminum can affected from heavy wind. Aluminum will bend and become hard to open and close, and it may accrue water leakage.
Filling between the aluminum and wall require a material to fill and prevent water, wind and insects. Filler by auks sealers, divided into three main types: Acrylic, Silicone and Polyether.
Acrylic use as indoor filler, moisture affected it and it will collect bacteria. In other hand Silicone is indoor filler, but it’s an antibacterial product, which is transparent and can be customized to any color. The problem facing silicon is to connect with wall where it’s designed to indoor usage only. Polyethers products like SikaFlex made in Switzerland, it’s made for outdoor usage, it can resist the natural factors affect the filler.
First of all, rollers run over rails, these rails are available in plastic easy to break, therefore aluminum rails is better. There are several rollers types, single or double roller, and depend on how many K.G. it designed to load. Important aspect to understand for window panel, the ratio between height and width. Narrow panels will not open easily because it’s accrue bending moment during opening.
Basicly the aluminum profile depend on the thickness of the glass. Normally we use 6 mm and for large opening 8 mm. Notice that glass has high heat transfer coefficient, as a solution we use double panel glass. A two layers of glass and air in the middle, the static air has a low heat transfer coefficient. To improve this technology there is triple glass, made of three layers of glass and static air between them. For more information about glass sheet types, check Glass Sheets types topic.

It’s hard to select Aluminum Sliding/gliding windows, you need to have many information about producers. Also aluminum has many secrets than what we mention above. Keep always up to date and feel free to ask any question.
