– Installed during the construction process, the product is positioned before concrete is poured- Allows for any type of service to pass through concrete, providing up to 4 hours fire and acoustic protection at the point of penetration
– A long-term solution, allowing fire-rated services to be factored in during the design process of new builds
Secure the Envirograf® cast-in sleeve with loops of wire passed through the
fitting lugs and through the steel reinforcement mesh before casting.
Immediately after casting the concrete, wipe both end caps with a damp cloth
to clear any spilled concrete and allow to set in place.
Release the end caps by scoring around the rim tape with a sharp knife
Remove the end caps.
Use a sharp knife to cut the end caps to accommodate services and re-install
into the cast-in sleeve to complete the job.
