Introduction: Why is it important to choose the right fire seal installation method?
In the event of a fire, the quality and installation of fire seals directly affects the safety of cabinet doors, gun cabinets, safes and other equipment. A securely installed seal not only effectively blocks smoke and flames, but also maintains a seal in hot environments, providing better protection for items.
However, when choosing a fire seal, many people tend to overlook the impact of the way it is affixed. The common installation methods on the market today are ordinary adhesive backing and mesh format backing, but there are obvious differences between the two in terms of adhesion, durability and adaptability. So, what are the advantages of mesh format adhesive backing compared to ordinary adhesive backing? This article will take you in-depth understanding.
Grid format adhesive vs ordinary adhesive backing: installation structure comparison
Ordinary adhesive backed sealing strip
The back is a uniform adhesive layer, suitable for smooth and flat surface.
In humidity, high temperature, long-term use of the environment may appear viscosity decline, edge warping or fall off.
It is suitable for short-term use or less demanding fireproof sealing scenarios.
Mesh backed sealing strip
Adopting grid structure of adhesive layer to enhance glue penetration and improve adhesion stability.
Suitable for different material surfaces such as metal, wood, etc., especially for slightly rough and irregular surfaces.
High temperature resistance is stronger, and it can still remain firmly fixed under fire conditions to ensure the sealing effect.
Core advantages of adopting mesh backing
1. Stronger adhesion, applicable to a variety of materials
The structure of the grid format adhesive backing enhances the penetration of the adhesive, which is more firmly adhered to different materials such as metal, wood, etc. than ordinary adhesive backing, which is especially suitable for the installation needs of gun cabinets, safes and other equipment.
2. High temperature resistance and better durability
Ordinary adhesive backing may soften or lose adhesion under high temperature, while the grid backing can maintain good adhesion under fire environment up to 650°C (1200°F), ensuring that the seal will not fall off due to high temperature.
3. Adaptable to uneven surfaces for easier application
For materials with subtle bumps or textures, it may be difficult for a regular adhesive to fit perfectly, while a mesh adhesive will fit the surface better and improve sealing performance.
4. Reduce the risk of peeling and ensure long-term stability
The special structure of the mesh backing reduces the risk of the seal falling off due to humidity, temperature change or long-term use, and maintains a longer service life in all environments.
Applicable Scenarios
Fire sealing of complex surfaces
Mesh backing adhesive has strong adhesion to slightly bumpy or coated surfaces and can be applied directly without sanding.
Long-term sealing in dynamic environments
The air permeability of the mesh reduces the cracking of the adhesive caused by thermal expansion and contraction, and makes the adhesive bond more durable.
Easy and fast installation
Tear and stick, no need for professional tools, non-technical personnel can also operate.
Compared with ordinary adhesive backing, mesh backed sealing strip performs better in terms of adhesion, high temperature resistance, adaptability and durability. Choosing the right installation method not only enhances the fireproofing effect, but also reduces the risk of sealing strips falling off and improves the safety performance of gun cabinets, safes and fire doors.
