RectorSeal Blaze Foam is intumescent compressible foam used to firestop head of gypsum wall joint applications both dynamic and static.
Designed for installation within fire resistive joints with up to 2 hours F rating, RectorSeal Blaze Foam provides dynamic movement with up to 50% compression (see UL systems) and 100% extension capabilities for max joint width 1/4″ to 1″.
RectorSeal Blaze Foam is simple to install for head of wall applications. Compress the Blaze Foam into the joint between the top of the wall and bottom of the deck so that the intumescent strip is facing the wall surface. RectorSeal Blaze Foam can be recessed into the joint or installed flush with the outside surface of the wall. Joints are butted together. No mechanical fastening of Blaze Foam is required.
RectorSeal® Introduces Blaze Foam™Firestop Foam Strips for Construction Wall Joints
Blaze Foam™ compressible intumescent strips are designed for head-of-wall, bottom-of-wall and wall-to-wall joints; install 75% faster than conventional methods.
RectorSeal®, Houston, a leading manufacturer of quality firestop construction products, introduces Blaze Foam™, a compressible, fast installation intumescing foam strip for firestopping dynamic and static head-of-wall, bottom-of-wall and wall-to-wall joints.
Blaze Foam is a charcoal-colored, 48 x 5/8 x 1.5-inch (121 x 1.5 x 3.8-cm) polyurethane foam strip designed for easily compressing by hand into construction joints on both sides of the wall up to 1-inch-wide. The compressible firestop increases project productivity, reduces jobsite waste and cuts firestopping labor installation time by 75-percent versus traditional firestop caulking methods.
Blaze Foam was tested in accordance with UL 2079 and ASTM E1966, and is compliant with the International Building Code (IBC), the National Fire Protection Association (NFPA) and all other building codes. The compressible firestop classified as a fill, void or cavity material and carries an F rating up to 2 hours. The assembly has 50-percent movement capabilities, and was cycled 500 times in a range of 1/4-inch to one-inch in tests.
Other benefits of Blaze Foam include:
Stays secured without the need for mechanical fasteners;
Uses no asbestos or hazardous materials;
Expands during a fire and prevents flame and smoke leakage under UL-2079 test standards;
Guaranteed to last the sustainable life of the building when applied via manufacturer’s requirements;
Requires no maintenance;
Intumescent expansion activation begins at 375°F (190°C) and expansion is greatest at 575 to 1,100°F (302 to 593°C).
