25mm Aluminium Foil-Faced Ceramic Fiber Blanket

Product Introduction

25mm Aluminium Foil-Faced Ceramic Fiber Blanket is an upgraded product, comprising a high-performance ceramic fiber blanket laminated with an aluminium foil layer using a specialized adhesive. This composite structure creates a dual "insulation + reflection" mechanism: the foil layer efficiently reflects radiant heat, significantly boosting overall insulation performance. Simultaneously, it serves as a robust physical barrier against moisture and dust, and completely contains loose fibers, eliminating skin irritation risks and ensuring a clean, safe installation and working environment.

Core Advantages

Dual "Insulation + Reflection" Protection: The ceramic fiber base effectively blocks conductive heat transfer, while the surface aluminium foil layer reflects most radiant heat. Their synergy provides significantly superior insulation compared to single-material solutions.

Comprehensive Physical Protection: The dense foil layer acts as a durable barrier, effectively resisting moisture and dust ingress, protecting the internal fiber structure from degradation, and ensuring long-term, stable thermal performance.

Safe and Clean Installation: The complete foil encapsulation prevents the release of loose fibers, eliminating skin irritation and itching upon contact, and fostering a healthier, more user-friendly working environment.

Lightweight, Flexible & Easy Installation: Retaining the excellent flexibility of the base ceramic fiber blanket, the product is easy to cut and wrap, conforming quickly to complex shapes and greatly improving installation efficiency.

Typical Applications

Industrial Furnaces & Pipelines: Widely used as insulation lining for various industrial furnaces and for insulating high-temperature pipelines and valves, improving energy efficiency.

Thermal Equipment Sealing: Used as sealing curtains for furnace doors, inspection ports, and other high-temperature openings, effectively reducing heat loss.

Sensitive Area Protection: Particularly suitable for areas with high cleanliness requirements, such as food drying lines and pharmaceutical workshops, preventing fiber contamination.

Personnel Burn Prevention & Energy Saving: When wrapped around accessible equipment surfaces, it reduces touch temperature to prevent burns while also saving energy.

Technical Indicators

Professional Installation Guide for 25mm Aluminium Foil-Faced Ceramic Fiber Blanket

Core Principle: Aluminium foil surface must face the heat source, with tight seams and secure fastening.

01 Pre-Installation Preparation

Surface Treatment: Ensure the equipment surface is clean, dry, and free from oil, rust, and sharp protrusions to prevent material puncture.

Material Cutting: Use utility knives or scissors to precisely cut the blanket to required dimensions, maintaining clean and even edges.

02 Installation Direction & Fixing

Direction Confirmation: The shiny aluminium foil surface must face the heat source (high-temperature side) during installation. This is crucial for maximizing its heat reflection functionality.

Fixing Methods:

Strapping Fixation (Preferred): Use stainless steel straps or high-temperature resistant steel wires for bundling, suitable for pipelines and regularly shaped equipment.

Adhesive Fixation: In low to medium temperature areas (≤400°C), high-temperature resistant adhesive can be used for bonding.

Welded Fixation: For high-temperature equipment, weld insulation pins and secure with matching washers.

03 Joint Treatment

Lap Requirements: All joints should have a minimum overlap of 50mm.

Sealing Reinforcement: For critical sealing areas, it is recommended to apply high-temperature sealant in the lap joints to thoroughly prevent heat leakage.

04 Multi-Layer Installation Advice

If multiple layers are required, stagger the joints between adjacent layers by at least 100mm to effectively block heat bridges.

05 Safety & Important Notes

Personal Protection: Wear gloves and masks during construction to ensure a safer working environment.

Gentle Handling: Avoid excessive stretching or compression to maintain the material's integrity.

Comprehensive Inspection: After installation, inspect all fixing points and joints to ensure there are no omissions.

FAQ

Q1: Will the aluminum foil layer detach or melt under high temperatures?

A1: No. The foil is bonded using a specialized high-temperature adhesive, whose thermal resistance matches the ceramic fiber blanket, ensuring the foil remains securely attached within the product's operational temperature range. Furthermore, the industrial-grade aluminum foil used has a melting point significantly higher than the product's maximum long-term service temperature, preventing any risk of melting.

Q2: How much does this product improve thermal insulation compared to a standard ceramic fiber blanket?

A2: Thanks to the highly reflective aluminum foil layer, this product significantly enhances overall thermal resistance. In high-temperature applications (e.g., ≥700°C), the cold face temperature is typically 10%-20% lower compared to a standard blanket without foil when the hot face is at the same temperature, resulting in substantially better energy savings.

Q3: Can the product be safely handled or installed in personnel-dense areas?

A3: Yes, absolutely. The aluminum foil layer fully encapsulates the fibers, effectively preventing the release of loose fiber debris. This eliminates the skin irritation and respiratory concerns sometimes associated with handling standard ceramic fiber blankets. Consequently, it is particularly suitable for hygiene-sensitive industries like food and pharmaceuticals, and for areas where personnel safety is a priority.

Q4: Is it suitable for use in damp or oily industrial environments?

A4: Yes. The aluminum foil layer provides excellent resistance to moisture and oil, effectively blocking water vapor and most industrial oil vapors. This protects the internal fiber structure from degradation, ensuring stable and durable thermal performance even in challenging conditions like damp, dusty, or oily environments.
