How to Measure Arch Top & Bottom Glass for Woodstoves

A replacement ceramic glass for woodstove can be cut to almost any shape and we custom manufacture each piece to your exact specifications.

Some shapes can be best measured with a tape measure, others may be more complex and require a paper pattern. The Arch Top and Bottom is the shape of a barrel on its side.

Method One: Direct Measurement Method

Arch top glass with distinct corners can be easily measured with a simple tape measure. It is easiest to take measurements directly from the glass you are replacing to ensure a good fit.

Measurements should be within 1/16”, so please be as precise as possible.

1. Thickness: How thick is the piece of glass that you need? Most woodstove glass is 3/16” thick (Neoceram). Ceramic glass also is available in 1/8” and non-transparent 5/32” thicknesses.
2. Width: First measure the overall width (w).
3. Max Height: Measure overall height (H1) at the highest center point of the arches.
4. Min. Height: Measure the height at the sides of the piece (H2). This shape assumes that the curve along the top and bottom are smooth lines.

Method Two: Paper Pattern Method

Tracing a paper template or pattern is used for complex shapes where measurements are difficult to take. An example would be when the arch-top & Bottom glass has a corner or corners with a radius.

Paper patterns are a tracing of the current glass that is being replaced. You can make a tracing of your glass on a large piece of butcher paper/cardboard/grocery sack/etc. and then mail the paper pattern to us.

Woodstove glass is best made from transparent ceramic glass called NeoCeram Glass® or Pyroceram Glass® that can tolerate constant temperatures up to 1292 degrees Fahrenheit and can withstand short term heat exposure to 1472 degrees Fahrenheit. This is ideal for woodstoves and pellet stoves.
