Extensive features of glass

Glass is a non-crystalline amorphous solid that is often transparent and has widespread practical, technological, and decorative usage. It can be colored by adding metallic salts, and can also be painted and printed with vitreous enamels. These qualities have led to the extensive use of glass in the manufacture of art objects and in particular, stained glass windows.

Applications of silicate glasses derive from their optical transparency, giving rise to their primary use as window panes. Glass will transmit, reflect and refract light; these qualities can be enhanced by cutting and polishing to make optical lenses.

Glass has become a part of human fascination since it first appeared in Roman homes many centuries ago. This fascinating material has evolved with dramatic speed that it is now used not only in residential buildings but also in large commercial edifices. At times, glass is even used to replace exterior building materials like bricks, cement and granite.

Glass has come to prove that in addition to its beauty and artistic appeal, it can also offer durability as one of its most important uses in modern architecture. It helps to conserve energy by allowing light to penetrate through, bringing brightness and warmth to an otherwise dark and cold home or office room.

 Most common types of glass

·        Sheet glass used for mirrors, picture frames, and glazing of floors or walls.

·        Float glass has better quality than sheet glass. It is not characterized by bubbles, knots or scratches. People use them in window panes because of its optical clarity and quality.

·        Tinted glass heat-absorbing quality makes tinted glass an effective energy-saving device especially in air-conditioned buildings. Tinted glass is most commonly used in doors and windows.

·        Heat Reflective glass is coated with layers of metal oxide film to enable it to reflect light and stay transparent at the same time. It is most commonly used in outer walls, doors and window panes of air-conditioned buildings.

·        Laminated Safety Glass is produced by bonding together two or more layers of glass and putting between them an inner layer made of polyvinyl butyl. Bonding is done by subjecting the glasses to heat and pressure. This special type of glass is used in aquariums, bullet proof glasses, and wind screens in automobiles and high-rise buildings.

WHAT ARE SLIDING DOORS?

A sliding door is a type of door which opens horizontally by sliding, usually parallel to a wall. Sliding doors are commonly used as shower doors, glass doors, screen doors, and wardrobe doors.

The sliding door system was invented to fit large openings for glass. These systems are manufactured for sliding doors to meet the specific needs of homeowners and are manufactured in clad or wood frames with various colors to choose from. The system was designed to keep water and air out of the space.

What is the mechanism used for operating sliding door?

The mechanism used to operate a sliding door is called sliding door gear. There are two standard types, top hung or bottom rolling systems.

• Top hung sliding doors: This is one used more often among all. The door is hung by two trolley hangers at the top of the door running in a concealed track; all the weight is taken by the hangers, making the door easier to move. At each end is a track stopper to absorb any impact made if the door is slammed and to hold the door in the open or closed position. The mechanisms are safe and the bottom of the doors is held in place on tracks. The rollers also have safety locks that prevent the doors from jumping of the tracks.

• Bottom rolling door gear: A bottom rolling system consists of two rollers at the bottom of the door running on a track and two guides at the top running in a guide channel.

• Lift-and-slide door gear: A sliding door that is lifted from the frame during opening and closing is called a lift-and-slide door. This allows for a better seal, with less drought and better sound proving.

Automatic sliding doors

Some sliding doors contain a motor and activation system to open them. These are called sliding door operators. Automatic sliding doors are commonly found in offices and shop entrances. These doors contain a magnetic locking mechanism that automatically unlocks during emergencies.

Benefits of sliding doors

• Sliding doors can be efficient insulators, ensuring that your home stays warm in the winter and cool in the summer. Sliding doors that are fitted with composite gaskets offer optimal thermal insulation – effectively acting as a weather and sound barrier, and keep dust, drafts and rain out of the home.
• Sliding doors installed with shatterproof safety glass provide optimal safety.
• Sliding doors operate without a hinge therefore no extra space is required for the door arc because they simply open up by one door sliding over another panel.
