Standards and Applications of Fire-Resistant Windows

Fireproof windows refer to windows that are made of steel window frames and steel window sashes, with non-combustible materials filled in the frame and sash, and equipped with fireproof glass and hardware to meet the requirements of fire resistance integrity and heat insulation. Fireproof windows play the role of isolating and preventing the spread of fire. Fireproof windows are one of the fire separation facilities of buildings, usually used in fire walls, and play an important role in reducing fire losses.

Fireproof window types

Fireproof windows are divided into two types: fixed and movable.

Fixed fireproof windows: Fireproof windows that are sealed and fixed on all sides and cannot be opened.

Movable fireproof windows: The window sashes can be opened. When a fire occurs, the movable window sashes can be automatically closed within 60 seconds under the action of the fireproof window.

Uses of fireproof windows

Fireproof windows are mainly used in fire partitions, escape routes, refuge corridors, fireproof walls, refuge floor fireproof windows, etc. in buildings. They have fireproof and heat-insulating functions and automatic closing functions, and play a role in fireproof separation. The glass used is fireproof and heat-insulating glass, which is an important fire prevention measure for important buildings.

Installation requirements

1. Acceptance When receiving the goods, Party A shall carefully check the quantity, specifications, grades and various accessories according to the supply contract to see if they are qualified and complete.

2. Storage and storage Fireproof windows should be stored vertically in a dry room and anti-corrosion measures should be taken. The glass should be placed and leaned against objects that will not damage the glass edges and glass surfaces.

3. Installation

(1) Fireproof windows must be inspected before installation. If the window frame or window sash is warped, deformed or the glass is broken due to careless transportation and storage, it should be repaired before installation;

(2) When installing fireproof windows, it is necessary to use a level ruler to level or use the hanging line method to correct the verticality of the front, back, left and right sides to ensure that they are horizontal, vertical and the same height;

(3) The window frame must be integrated with the building and connected to the wall with wood or iron parts. After the steel window frame is installed, cement mortar must be poured between the window frame and the wall, and it must be cured for more than 24 hours before normal use;

(4) The position of the hardware installation holes should be accurate so that the hardware accessories can be installed flat and firmly to meet the use requirements;

(5) When installing fireproof glass, the gaps on the four sides must be even. After positioning, the gaps on the four sides should be filled and leveled with fireproof cotton, and then the edge strips should be sealed;

(6) In addition to the above requirements, the installation should be carried out in accordance with the requirements of the "Engineering Construction and Acceptance Specifications".
