RectorSeal® Blaze Foam™

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.

Blaze Foam™ Firestop

BlazeFoam FirestopRectorSeal® 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).
  • and complements RectorSeal’s full line of firestop products for construction materials, construction joint protection, and wall/ceiling wall penetration sealing in HVAC, plumbing, electrical and other trades .

Blaze Foam has a 10-year shelf/storage life and is available in an 80-piece carton from building materials wholesale distributors. See the product: http://www.metacaulk.com/index.php/rectorseal-blaze-foam/

1000fcia.org’s latest issue has an excellent artcile about whether or not to choose firestop systems or fire caulk:

MANY HAVE HEARD ABOUT ‘FIRESTOP.’ WAIT, WHAT? WHAT’S FIRESTOP? Firestop is a tested and listed SYSTEM. The SYSTEM comes from the many fire tests conducted at leading laboratories like FM Approvals, Intertek or Underwriters Laboratories. The manufacturers of these materials invest a lot of money and time ensuring that they—the materials— in fact, work for the specific application and required time, based on proven fire test procedures, such as ASTM E 814 and UL 1479 for penetrations and ASTM E 2307, ASTM E 2837, ASTM E 1966 and UL 2079 for joints. Therefore, firestopping should be all about listed, classified firestop SYSTEMS. The SYSTEMS are an assemblage of materials—the floor or wall assembly, annular space or joint size, type, size of penetrating item and possible coverings that have been tested for a particular application, a particular hourly fire-resistancerating and/or smoke-resistant property. The SYSTEMS are then listed and classified by FM Approvals, Intertek or UL, and/or other credible independent third-party testing labs. Now we come to the installation of these firestop systems, and it seems that despite the hundreds of millions of dollars invested by the manufacturers in testing, that some in the industry continue to refer to it as, “we installed the fire caulk, so the floor and wall are now rated.” Really? There’s a magic product that provides fire-ratings?

Metacaulk® Box Guard™

Metacaulk® Firestop for Electrical Outlet Boxes

Metacaulk® Box Guard™ is a highly intumescent, fire-rated pad for use in electrical boxes. When complying with the “24 inch rule”, it is inserted on the inside back wall of an electrical box.

When exposed to fire, Box Guard™ will expand forming a char that will seal off the opening and prevent the spread of flames and limit the temperature rise on the unexposed surfaces. A labor saving, economical alternative to putty pads. Great for retrofit jobs. STC 53 Rating, Tested in a UL 411 wall assembly/section to ASTM E90.

US Patent No. 6,207,085 & 6,252,167

Techniques and Specifications to Reduce Building Fire Fatalities and Injuries

wc1113-FEAT5-Fire-p1SLMost construction specifiers, architects, engineers and contractors are aware of the National Building Code’s firestop compliances, but proper materials and application techniques are many times overlooked, which could lead to needless injuries and fatalities in a commercial building fire. Furthermore, using firestop materials economically can save a project tens of thousands of dollars without affecting efficiency or limiting life safety.

Hundreds of lives are saved and thousands of injuries are avoided annually during building fires, because of recent advancements in construction-phase firestopping efforts that minimize the transmission of smoke and other combustion byproducts into abutting areas.

Firestopping is a material or combination of materials used in re-establishing the fire-rated integrity of a wall or floor assembly that has been compromised by the inclusion or exclusion of a penetrant. Walls and floors in commercial buildings are code-compliant to fire ratings. However, if a penetrant, such as a pipe, cable tray or HVAC duct, alters the wall or floor’s fire rating, it must be restored with an approved firestopping system. The goal is to eliminate the transmission of a fire’s smoke, flames and hot gases from passing through the penetration into another room and buy more time for occupants to escape.
