Frequently Asked Questions about Thermo-Lite Board®

1. What is Thermo-Lite Board®?

Thermo-Lite Board® is a unique closed cell, lightweight composite panel manufactured with cross-linked polymer foam and fiberglass, offering high specific strength and toughness. The non-absorbent material is extremely durable and dimensionally stable, provides an excellent bonding surface, has good impact strength, sound and thermal insulation, and is resistant to contamination and high temperatures.

2. Will Thermo-Lite Board® hold/retain screws, rivets and/or staples?

Thermo-Lite Board® is available in various densities and strengths. When using our Core or Versatile series boards we would recommend using adhesives or resins to join or coat the boards.
When using Tough-Lite, Tough, or Supreme series boards there is a higher density and high strength woven matting making the board suitable to retain screws, rivets, and staples, When screwing Thermo-Lite Board® we recommend backing of on your drill speeds and using course screws (i.e. gyprock or metal screws) when screwing into Thermo-Lite Board® for the best retention.

5. What tooling should I use when cutting Thermo-Lite Board®?

Thermo-Lite Board® will accept standard tooling and hardware for cutting and drilling.
We suggest through-bolting and up-sizing the washer/head diameter if possible. In comparison to plywood, we also recommend reducing the torque when fastening into the material. The fastener performance varies with fastener style, size and torque as well as with product Series and density. We recommend using course based screws i.e. gyprock or metal screws for best retention.
Hardware qualification must be established on the user level.
