Fireproof Window

The design method of using the outer layer as an aluminum alloy profile and the inner layer as a steel profile has both a skeleton effect of the steel when it is fired and a beautiful appearance of the aluminum profile. It is a quality product on the market that can match the exterior windows of fire-resistant integrity of major buildings.

Product Stucture:

The outer layer is made of 1.4mm thick aluminum, and the surface can be sprayed with powder or fluorocarbon. It can also be treated by different methods such as anodizing and electrophoresis, and has different color choices.

The inner layer is made of 1.2mm thick galvanized steel sheet, which is cold-rolled and has excellent anti-rust ability. For example, the color-coated steel plate has better anti-rust ability.

The dimensions of the aluminum profile and the steel profile are accurate, so that the two are combined into one, no welding is required, and the slit is simply rust-proofed, and the window can be combined by a special connector.


Product performance - meet the five advantages of building exterior windows

1. Wind pressure resistance: 9

Using standard cross-section aluminum material, the wind pressure resistance of this product is Classification and testing method for airtight, watertight and wind pressure resistance of building exterior doors and windows GB/T 7106-2008, which can reach level 4, it can reach grade 9 or above with reinforced profiles.

2. Watertight performance: 6

The watertight performance of this product can reach Grade 6 of GB/T 7106-2008 Classification and Detection Method of Airtight, Watertight and Wind Pressure Resistance Performance of Building Exterior Doors and Windows.

3. Airtight performance: 8

The airtight performance of this product can reach Grade 8 or above of GB/T 7106-2008, which is classified as Airtight, Watertight, Wind Pressure Resistance Rating and Detection Method for Exterior Doors and Windows.

4. Thermal performance: 2.0w/(m • K)

Different glass can be used to achieve different shading requirements. For example, LowE glass and thermal insulation section can be used with a K value of 2.0, which is actually based on the configuration of the order glass.

5. Fire performance: C1.0h

This product is specially developed according to the requirements of the Code for Fire Protection of Building Design GB50016-2014 for the external window of residential shelters. It can meet the requirements of Class C non-insulated fire windows and fire resistance integrity of 1.0 hours.

With the ordinary aluminum alloy window, the manual opening and closing function can be adopted; when the window closing device is installed, when the fire is encountered, in the open state, the thermal element is triggered, and the window sash is automatically closed.
