Not all glass is the same. The right type depends on your application, performance requirements, and local building codes. This guide covers every glass type we install across Washington DC, Northern Virginia, and Maryland -- written by our certified glass professionals with 20+ years of field experience.
These are the six most commonly specified glass types for residential and commercial projects in the DMV. Each card includes key performance ratings, best applications, and a link to the full detail page.
Heat-treated safety glass that is 4x stronger than standard annealed glass. When broken, it shatters into small, blunt pebbles instead of dangerous sharp.
Best Uses
Two or more glass layers bonded with a PVB (polyvinyl butyral) interlayer. Holds together when broken, blocks 99% UV radiation, reduces sound.
Best Uses
An invisible metallic coating that reflects infrared heat while allowing visible light through.
Best Uses
Double or triple pane units (IGUs) with sealed air or argon gas gaps between the panes.
Best Uses
Acid-etched or sandblasted glass that diffuses light for visual privacy. Transmits 75-85% of light while completely blocking visibility -- ideal for.
Best Uses
Textured, patterned, and custom-designed glass for aesthetic appeal. Includes reeded, fluted, rain, seeded, and art glass options that combine visual.
Best Uses
Beyond the six primary types, we also install these specialty glass products for specific performance requirements and applications.
Low-iron glass with 91% light transmission and zero green tint. True color rendering for display cases, frameless showers, and designer applications.
Learn MoreColor-infused glass in gray, bronze, green, or blue that reduces glare and solar heat gain by 25-50%. Provides daytime privacy from the exterior.
Learn MoreWire-reinforced glass for fire-rated doors, windows, and corridors. The embedded wire mesh holds broken glass in place during a fire for up to 45 minutes.
Learn MoreCeramic and borosilicate glass systems rated for 20 to 180 minutes of fire resistance. Required by code for stairwells, corridors, and fire-separation walls.
Learn MoreAcoustic laminated glass that reduces noise by up to 85%. STC ratings from 35-55 for airport, traffic, and urban noise -- ideal for DC and Northern.
Learn MoreEngineered to withstand wind-borne debris and forced entry attempts. Laminated and tempered combinations provide maximum storm and security protection.
Learn MoreGlass with a metallic reflective coating -- silver (95% reflectivity) or aluminum (85%). Custom cut, beveled, and polished for bathrooms, gyms, and decor.
Learn MoreStandard annealed glass and the base product for all specialty types. Made by floating molten glass on liquid tin for perfectly flat, uniform sheets.

Different installations call for different glass types. Here is what we recommend for the most common residential and commercial projects in the DMV.
Quick reference points from our glass professionals to help you make informed decisions.
Any glass within 24 inches of a door, within 18 inches of the floor, in bathrooms, or in railings must be tempered safety glass per Virginia, Maryland, and DC building codes.
You cannot see or feel a Low-E coating on glass. The microscopically thin metallic oxide layer is applied during manufacturing and does not change the appearance of the glass.
Properly sealed insulated glass units lose argon gas at roughly 1% per year. After 20 years, the unit still retains about 80% of its insulating gas fill.
Standard glass blocks about 97% of UVB rays but only 37% of UVA rays. Laminated glass blocks 99% of both types -- protecting furnishings and flooring from fading.
When laminated glass breaks, the PVB interlayer holds the fragments together like a web. This is why it is required for skylights, overhead glazing, and hurricane zones.
Acid-etched and sandblasted frosted glass is a permanent surface treatment -- it cannot wash off or wear away. Frosted film, by contrast, is removable but less durable.
