INTU-FX (Intumescent Fire Expandable) Legacy's intumescent material expands rapidly when exposed to heat or high temperatures. This stops fire expansion through the gaps around doors. Type #3 expands up to 30 times and Type #4 expands up to 120 times.
Other expansion rates and material sizes are available! Please contact us for other non-standard options.
