Difference between insulated and non-insulated fire windows

Fire window is a kind of fire isolation facility set between fire zones. Its function is the same as that of fire doors and fire shutter doors, but it has two other characteristics that it does not have, namely permeability, unlike doors and shutter doors, which are closed.

The frame materials of fire windows are common steel, stainless steel and wood, and steel fire windows are widely used in the market.

The main core of fire-proof window is fire-proof glass, which must meet the relevant national testing standards. According to the different manufacturing principles of glass, it can be divided into heat-resistant fire-resistant glass and non-heat-resistant fire-resistant glass, mainly represented by grouted A-grade heat-resistant fire-resistant glass and single cesium-potassium fire-resistant glass. The latter has no heat insulation effect, so the windows made are called non-heat insulation fire windows.

Using insulated and non-insulated fire windows has its own advantages and disadvantages. Because the interior of the thermal insulation fire-proof window is filled with flame-retardant liquid, if it is placed in an area exposed to long-term sunlight, bubbles may be generated, and the color of the liquid becomes darker, which affects the appearance; This kind of problem does not exist in the fireproof window made of single cesium-potassium fireproof glass. On the contrary, single-layer glass does not have heat insulation function. The use effect is not as good as that of grouting glass. Consumers can choose suitable fire windows according to different use positions.
