Brick Veneer Fire Wall

A nominal 4 in.

Brick veneer fire wall.

15 9 mm thick gypsum wallboard. 92 mm wide 1 in. The most common wall assembly is defined by a facing of thin brick between 1 2 to 11 in thickness applied over a plaster backing. 51 mm thick foamed plastic rigid insulation 2 in.

The chemical composition of dense firebricks is different from that of regular bricks. Additionally fire bricks must be able to withstand different atmospheres provide various structural or insulating qualities and due to the difficulty in cutting them must be available in a variety of shapes to add flexibility to kiln design and construction. External walls including gables are required to be of masonry veneer or masonry construction 90mm thick. They are different from regular masonry bricks because of their ability to withstand temperatures up to 1 800 degrees fahrenheit.

Brick veneer wall assemblies with wood stud backing routinely attain fire ratings of up to 2 hr. For further information on fire resistance of brick see technical notes 16 and 16b. Adhered brick veneer is defined as brick veneer secured and supported through adhesion to an approved bonding material applied over an approved backing. 406 mm o c studs cut in.

This is done by extrapolating from known fire resistance periods for a given thickness of wall. 19 1 mm less than assembly height. U418 and u425 vary in rating between æ to 2 hours and are brick veneer drainage walls with steel studs and gypsum sheathing and wallboard. Brick veneer steel stud non loadbearing 1 layer in.

41 mm legs 20 gage steel studs spaced 16 in. Fire resistance of brick masonry. Firebricks are blocks of refractory ceramic materials used to line fireplaces fire boxes and furnaces. A brick wall s fire resistance rating can be calculated.

Timber or steel framed walls must be sarked on the outside and clad with 9mm fibre cement or steel sheeting alternatively bushfire resistant timber. As such it is an excellent cladding choice to resist or confine fires. Fire resistance ratings of several brick masonry wall assemblies tested using astm e119 procedures are listed. Made out of non combustible material masonry brick veneer etc.

Be tested for bushfire resistance to as 1530 8 1. Fire brick is a generic term that encompasses any brick that can withstand repeated heating and cooling at various temperature ranges. Where the external wall does not extend to the underside of the roof mineral fibre should be included. 102 mm brick wythe alone provides a 1 hr fire resistance rating for the exterior surface of the wall.

51 mm air space. Since the primary ingredient in brick is clay which is fired to around 20008 f it is a non combustible material. Refer to technical notes 16b for further. Soffits should have a non combustible eaves lining.
