Stress Plates

Sarnaplate

Sarnaplate is a specially-designed stress plate used with Sarnafasteners to attach an insulation board directly to steel roof decks prior to the installation of the Sarnafil mechanically-attached or adhered roof membrane.

Sarnaplate Low Profile

Sarnaplate-Low Profile is a specially-designed stress plate used with #12, HD (#14) and XP (#15) Sarnafasteners to attach insulation and hard cover boards such as Dens-Deck products directly to steel, wood, and concrete roof decks prior to the installation of Sika Sarnafil adhered roof system. Sarnaplate-Low Profile is not recommended for use directly over a plywood or OSB surface (such as Nailboard Insulation).
