New Technical Bulletin on Blazeguard SIP finishing techniques

Barrier's Blazeguard Fire-Rated Sheathing provides an ideal interior-face fire barrier for Structural Insulated Panels (SIPs). Our Blazeguard coating meets and exceeds the 15-minute thermal barrier required by the International Building Code (IBC Section 2603.4) and is cited in our ICC Evaluation Services Report ESR-1365 in Section 4.2.d.

Blazeguard is particularly well-suited to the SIP market as it is a factory-applied thermal barrier, obviating the need (and the cost) to install fire-rated gypsum or other fire barriers in the field. In essence, Blazeguard adds to the SIP value-proposition of delivering wall or roof panels that are "plug and play" -- deliver to the job site, drop them in, secure them and move on.

This 8' x 24' panel was manufactured as a Blazeguard SIPs. The interior face (facing towards the studs) has the Blazeguard fire-resistant material applied to it.

A new Barrier publication makes the process even more straightforward. Our new Technical Bulletin "Fire-Rated Finish for Structural Insulated Panels (SIPs)" (below), lays out the steps involved in treating panel seams, patching Blazeguard SIPs and painting or finishing the interior surface. The document also shows a recommended increased fastening regiment so that panel seams don't crack if panels move slightly over time.

Note that in addition to reduced labor, materials and time to finish the interior surface of SIP, Blazeguard SIPs have another inherent advantage over finishing a SIP face with gypsum: Blazeguard can be applied on any size panel up to Jumbo SIPs (8' x 24'), meaning that the total number of seams in a wall is reduced by up to a factor of six (fire-rated gypsum generally comes in 4' x 8' or 4' x 10' sheets).

SIP manufacturers and builders are encouraged to contact us at (800) 638-4570 for further information on how Blazeguard can help save considerable time and money on their next SIP construction project.
