While there are many types of fire-rated and fire-resistant glass available, Owen Sound Glass Service specializes in providing a small selection of both to our clients. We stock 5 mm ceramic glass for fireplaces, and 6 mm GPW and GCW glass for fire-rated applications.
What are the differences between the two? Fire-rated glass is typically used in doors and windows that need to meet fire codes, while fire-resistant glass is used in applications involving higher temperatures, such as in fireplaces or intense spotlight lenses.
Properties of Fire-Resistant Glass
We use Neoceram and Pyroceram fire-resistant glass, which are able to withstand temperatures in excess of 650 degrees Celsius (1200 degrees Fahrenheit) because of their transparent ceramic makeups. Ideally suited for fireplace and wood stove applications, Neoceram has a yellowish-amber tint to it.
Properties of Fire-Rated Glass
Because ordinary plate glass and tempered glass can’t withstand high temperatures without breaking, installing fire-rated glass is one of the most important ways to ensure a building meets fire code regulations. Fire-rated glass can contain fire and smoke, preventing or delaying them from spreading from one area of a building to another.
Two Varieties of Fire-Rated Glass
Fire-rated glass usually comes in two varieties: Georgian Polished Wire (GPW) and Georgian Cast Wire (GCW). While GCW glass won’t allow you to view anything but vague shapes and faint light through it, GPW glass is smoother and clearer, allowing for a clear view and a superior transmission of light.
These two types of glass get their name due to the mesh of steel wire found embedded within. This wire holds the glass together when it fails at high temperatures. You can find both types of glass in most schools, public stairwells, fire escapes and the interior entrances to most garages or parking structures.
