Aluminum clad wood, vinyl, and fiberglass are the most common materials to build replacement sliding glass doors. Aluminum cladding is a thin sheet of aluminum attached to a wooden door with an exterior-grade adhesive. On the other hand, Wood-clad doors have thin sheets of plywood on both sides of the core.

Sliding glass door hardware is necessary to hold the sections together and allow them to slide. There are different rollers for various applications, but all sliding glass door hardware requires regular maintenance to operate safely and smoothly. So, this matters when you buy a new sliding glass door.

Hardware Material

Stamped steel rollers, stainless steel rollers, or nylon rollers are standard for sliding glass door hardware. The best material depends on the situation. Forged steel is typically used in commercial applications because they have a longer life span than nylon or stainless steel. Nylon rollers are used when the weight capacity is over 100 pounds. Stainless steel rollers are best suited for marine applications or saltwater environments because they are corrosion resistant.

Glass Type

There are three different types of glass used in replacement sliding glass doors: heat-strengthened glass, tempered glass, laminated safety glass.

Heat-strengthened glass has four to five times more strength than annealed, making it the most common material used. Tempered glass is four to five times stronger than heat-strengthened glass, but it breaks into small pieces when it fails instead of large shards like annealed glass. Laminated safety glass has high strength and will not break apart when compromised; however, homeowners should make sure that the glass meets their local safety standards before choosing this option.

Glass Thickness

The glass thickness is determined by the weight of the door and the strength needed. Thicker glass has more material, which can weigh more than thinner glass. Glass that ranges from ⅜ to 0.5 inches thick is considered standard for replacement sliding glass doors. However, there are thicker glass options available for applications requiring high strength to increase safety.

Glass Coating

A variety of different coatings can be applied to glass, making it more durable and scratch-resistant. Tinted coatings reduce the amount of sunlight coming through the glass by absorbing specific frequencies of light waves. These types of coatings are perfect for meeting energy-efficiency needs. Decorative film can be used on the glass exterior to create patterns or images, whereas interior coatings are often applied to make it easier to clean.

Glass Appearance

Glass is available in two standard shapes; rectangular and arched. Different profiles change how the glass looks when viewed from the exterior. Profiles are popular for door replacement projects because it is the only way to make aluminum-clad doors match existing windows or doors on a house.
