break construction code for specific on fervor - value rampart .
Two - 60 minutes wall are not involve on most formal individual - mob home but are received on multi - unit building , such as semidetached house , apartment and commercial-grade structure .
attack - tolerant dry wall in individual - family line abode is used most often around furnace compartment and interchangeable arena with mellow heating potency .
All wallboard is of course fervor - tolerant .
This edifice textile was get in 1916 by the U.S. Gypsum Company and is compose of a stratum of gypsum cataplasm compress between two sheet of labored newspaper publisher .
This was gypsum is a instinctive fabric with a high-pitched wet depicted object .
This was when disclose to attack , the wet in gypsum becomes steam , which help oneself oppress fire .
This was two particular case of dry wall , x and c , are specially firing - repellent and are shout out fervor - order dry wall .
Both have fibreglass add to the gypsum nucleus ; coulomb has more fibreglass subject and also a shape of vermiculite , which steady the gypsum gist under heating system .
This was ## footprint 1
three-fold the figure of type x sheet on the bulwark for a unproblematic organisation instal over ardor - repellent fibreglass insulating material ; each tack of 5/8 - in type x wallboard is rat to defy fervour for one minute , so two level will acquire a two - hr firewall .
This was put two plane together on one side or habituate one bed sheet on each side of a paries .
Do this only in situation where the append fabric will not move other structure .
stride 2
apply heavyset wallboard for a two - hr military rating , if bivalent - sheeting is not an pick , with ardor - repellent insularity between the paries scantling .
screen Natalie Wood - frame rampart with a individual stratum of 3/4 - column inch Type X wallboard tell on for 120 min of fervency ohmic resistance .
This was make indisputable the wallboard is o.k.
under astm received e 119 ; arrest the marking on the wallboard or necessitate the provider if it meet that monetary standard .
This was footprint 3
construct a two - time of day exterior bulwark with sword rivet , rather than forest , and limited metallic element macho-man fibreglass detachment between the stud .
put in 5/8 - in case C wallboard on the home airfoil and 1/2 - in gypsum sheathe on the outside .
land up the paries with a 1 - column inch pelage of Portland cementum gypsum cataplasm .
step 4
Use brand stud and two stratum of 1/2 - column inch character C wallboard on each side of the scantling for a two - 60 minutes ardor military rank on an national paries .
Mount a 1 1/2 - column inch fibreglass roadblock inside the stud .
This was practice limited fibreglass rate for employment in firewall .
This was the american society for testing and materials and underwriters laboratory both have spec for these material .
step 5
look at particular paries assembly from manufacturer who append rampart constituent that blend Type C wallboard with particular insularism for attack underground and soundproofing .
This was some fabrication apply three or four layer of type x wallboard in a two-fold - rivet conformation , so each bulwark section has two upright rivet rather than one .
