Renovation companies embed fire-retardant cotton in concealed engineering to prevent the spread of electrical fires and reduce the risk of residential fires

Concealed engineering embedded fire-retardant cotton
Most residential fires are caused by electrical wiring faults, and each incident results in huge direct economic losses on average. Even more heartbreaking is that many affected families failed to implement fire-resistant isolation of circuits during renovation.
In traditional renovations, PVC conduits in the ceiling will melt and drip at high temperatures, and sparks can spread through the gaps in the light steel keel at a speed of 1.5 meters per minute—this is the culprit that reduces countless homes to ashes in an instant.
Fire-retardant protective net for concealed engineering
Ceiling fire barrier
Insert fire-retardant cotton boards into the gaps between the light steel keel framework; add double-layer fire-retardant cotton in areas with concentrated conduits, with a 20mm gap to form an air insulation layer; use L-shaped prefabricated fire-retardant cotton components at corners to eliminate blind spots in protection.
Wall conduit protection
Wrap fire-retardant cotton tape around the switch and socket boxes; wrap double-layer fire-retardant cotton sleeves around the intersection of strong and weak electricity.
Ground conduit fire protection
Lay fire-retardant cotton below the underfloor heating reflective film; seal the through-beam holes with fire-retardant cotton grouting material.
Why renovation companies choose the fire-retardant cotton solution
What are the advantages of fire-retardant cotton?
1. Fire risk drops dramatically
Flame retardancy: Fire-retardant cotton has a long-term temperature resistance of 200℃ to 300℃ and can operate stably, with an instantaneous temperature resistance of 1000℃. It has a high limiting oxygen index, does not burn when exposed to open flames, directly carbonizes, does not spread, and does not melt and drip.
Spread control: Forms a continuous fire barrier, controlling the burned area to a small range.
Toxic smoke suppression: Does not produce toxic gases after combustion.
2. Perfect compatibility with concealed engineering
Ultra-thin design: The thinnest 1mm fire-retardant cotton film can adhere to various irregularly shaped structures.
Non-destructive installation: Low elastic modulus, can automatically adjust with the deformation of the building structure.
Zero space occupation: The standard 12mm construction thickness only accounts for 6% of the total ceiling height.
3. Dual certification for environmental protection and health
No fiber shedding: Does not burn when exposed to open flames, no melting and dripping.
Environmentally friendly material: Does not produce toxic gases during combustion and is biodegradable.
