Building Explosion Venting & Blast-Resistant Products
Active Venting + Passive Blast Resistance — Science-based Dual Protection Strategy
Explosion Venting & Blast Resistance
TKC offers explosion venting doors, windows, louvers, walls, roofs and ceilings, alongside blast-resistant doors, walls and windows. Explosion venting releases pressure; blast resistance is a separate protection strategy. Confirm FM 4440 scope and each product's test data against the relevant product and project documentation.
Explosion Venting Series — Active Protection
FM 4440-certified DLC explosion venting panels actively channel and dissipate explosion energy before structural damage occurs. Precision-calibrated trigger pressure ≤ 1.92 kPa, millisecond-level response.
Blast Resistance Series — Passive Protection
Engineered blast-resistant doors, windows, and wall systems that absorb and withstand explosion overpressure. Ideal for control rooms, safe havens, and critical equipment enclosures. Rated ≥300 kPa to ≥1,000 kPa.
