FIRESTOP.
THE STANVAC STANDARD
A firestop for every opening on your drawing.
Building under construction. Illustrative scene.
Seal the opening. Protect the cable. Defend the panel.
Four fire-protection technologies. One coordinated specification.
32 years of industrial chemistry · 3 manufacturing plants · 41 industries
Trusted by Reliance, Adani, Tata Steel, SAIL and UltraTech.
Four technologies. One company.
Strong, economical seals for wall and floor openings.
Clean installation and future cable re-entry.
Flame-spread control and full-length circuit-survival systems.
Protects the painted surfaces inside electrical panels.
Use the test for the task: IS 12458 for penetration seals; IEC 60332 for cable flame spread; IEC 60331 for circuit survival.
What the building standard requires.
NBCS 2026 / SP 7:2026 / PART F - FIRE AND LIFE SAFETY
FM AND UL ARE NOT SPECIFIED.
Clause 3.5.4.4 cites IS 12458:2019 [F(34)] for these penetration seals. FM / UL certificates or ASTM reports alone do not establish IS compliance.
Both tests are required.
Fire test + mandatory hose-stream test. Require both results for the specified seal assembly.
A 2-hour wall needs a 2-hour seal.
At least 120 minutes for applicable cable / conduit openings [3.5.4.4]. Distribution-cable shaft seals at each floor must match the floor rating [3.5.5.1].
Where Part F applies.
Check occupancy, height and area. Examples: education, assembly and storage above 9 m; low / moderate-hazard industry over 2,000 m². Area triggers and shaft exclusions apply.
NBCS 2026 replaces NBC 2016.
SP 7:2026, effective 30 April 2026, provides national guidance. State bye-laws and fire-authority conditions govern acceptance; existing local bye-laws continue until amended.
An unsealed opening defeats a fire-rated wall.
Fire and smoke cross gaps; flames travel along cables. At handover: who specified the seal, and was it tested?
The full system range.
THE OPENING / THE CABLE / THE PANEL
A. Seal the opening.
NBCS Part F: 3.5.4.4 (penetrations); 3.5.5.1 (shaft floor seals).
Ratings apply to the tested assembly. Match the substrate, opening, services, seal depth and installation detail.
Installation illustrations.
B. Protect the cables passing through.
1 foot of EC 43 at every penetration. Included free.
The seal closes the gap. EC 43 limits flame spread along the cable.
EC 43 General: flame-spread protection tested to 240 minutes / IEC 60332-3 in the tested cable assembly.
Sealed opening + coated cables: two fire paths addressed. Installation illustration.
C. Add circuit and panel protection.
OPTIONAL UPGRADES
Local flame-spread control and full-length circuit survival are separate specifications.
4 reasons to specify STANVAC.
Tested to the cited Indian standard.
FIREX systems are tested to IS 12458:2019 at CSIR-CBRI, Roorkee, a Government of India laboratory. Use the relevant assembly report for project approval.
One accountable partner.
Survey, specification paragraph, drawings, method statements and trained applicators - coordinated firestop, cable and panel protection.
Two fire paths protected.
2 hours at the penetration plus cable flame-spread protection tested to 4 hours / 240 minutes. The 1-foot EC 43 coating is included free.
Why pay more for what the clause does not specify?
A lower-cost Indian alternative: IS-tested seal + free cable coating. Compare imported FM / UL offers on the complete installed package: seal, cable treatment, installation and documentation.
