What we seal
Electrical penetrations
Cables, bundles, conduits and cable trays, including multiple penetrations.
Ventilation ducts
Mechanical ducts and shafts, around dampers and sleeves.
Firestop joints
Head-of-wall, wall-to-slab, perimeter edge-of-slab and expansion joints in fire separations.
Openings and blockouts
Open penetrations, planned sleeves and openings left for future services.
Code compliance upgrades
Deficiency surveys and correction of penetrations in existing buildings.
Code compliant, ready for inspection
In Québec, the Construction Code requires that gaps around services passing through a fire separation be sealed with a firestop system tested to CAN/ULC-S115.
We install listed systems only, with the required rating (F or FT). When no listed system matches the configuration, we obtain an engineering judgment from the manufacturer.

Frequently asked questions
Your questions
What is a listed firestop system?
It is a precise combination of materials (sealant, foam, collar, mineral wool, etc.) tested with a given wall or floor type and a given penetrating item. Each system has a listing number and is valid only for the configuration tested.
What is an engineering judgment?
When a configuration does not match any listed system, the manufacturer’s engineer issues a technical opinion based on similar tests. This document must be accepted by the project professionals.
What is the difference between an F rating and an FT rating?
The F rating is the time during which the system prevents the passage of flames. The FT rating adds a limit on temperature rise on the unexposed side, required in certain situations.
Do you provide documentation for inspection?
Yes. When required, we provide a photo report with labelling of penetrations, which simplifies inspection and building turnover.
