Abstract
A fire resistant and water resistant expansion joint system comprises a core; and a fire retardant infused into the core. The core infused with the fire retardant is configured to define a profile to facilitate compression of the fire and water resistant expansion joint when installed between substantially coplanar substrates.
Claims59
A fire and water resistant expansion joint system, comprising:
- a core;
- and
- a fire retardant infused into the core;
- wherein the core infused with the fire retardant is configured to facilitate compression of the fire and water resistant expansion joint system when installed between substrates, and wherein the fire retardant infused core has a density when compressed of about 160 kg/m3 to about 800 kg/m3, and the fire and water resistant expansion joint system and the fire retardant infused core are capable of withstanding exposure to a temperature of about 540° C. at about five minutes, and the fire retardant infused core is configured to pass testing mandated by UL 2079.
1 more element
A fire and water resistant architectural joint system, comprising:
- a first substrate;
- a second substrate arranged at least substantially coplanar to the first substrate;
- and
- an expansion joint located in compression between the first substrate and the second substrate, the expansion joint comprising:
- a core having a fire retardant infused therein,
- wherein the expansion joint is compressed between the first substrate and the second substrate to accommodate movement there between, and wherein the fire retardant infused core has a density when compressed of about 160 kg/m3 to about 800 kg/m3, and the fire and water resistant architectural joint system and the fire retardant infused core are capable of withstanding exposure to a temperature of about 540° C. at about five minutes, and the fire retardant infused core is configured to pass testing mandated by UL 2079.

A fire and water resistant architectural expansion joint system, comprising:
- a first substrate;
- a second substrate arranged at least substantially coplanar to the first substrate;
- and
- an expansion joint located in compression between the first substrate and the second substrate, the expansion joint comprising:
- a core having a fire retardant infused therein by permeating the fire retardant into the core, and
- wherein a layer comprising the fire retardant material is sandwiched between the material of the core, and the core is not coated with any fire retardant material on any outer surface of the core, wherein the expansion joint is compressed between the first substrate and the second substrate to accommodate movement therebetween, and wherein the fire retardant infused core has a density when compressed of about 160 kg/m3 to about 800 kg/m3, and the fire and water resistant architectural expansion joint system is capable of withstanding exposure to a temperature of about 540° C. at about five minutes, and the fire retardant infused core is configured to pass testing mandated by UL 2079.
3 more elements
A fire resistant expansion joint system, comprising:
- a core;
- a fire retardant material permeated in the core;
- and
- wherein the fire resistant expansion joint system is configured to be installed in a gap between substrates and configured to facilitate compression during use to accommodate movement of the substrates as the fire resistant expansion joint system repeatedly cycles by expanding and contracting in the gap, and wherein the core with the permeated fire retardant material has a density when compressed of about 160 kg/m3 to about 800 kg/m3, and the core with the permeated fire retardant material is configured to maintain fire resistance upon exposure to a temperature of about 540° C. at about five minutes, and the core with the permeated fire retardant material is configured to pass testing mandated by UL 2079.
