Felt Spacer Sleeve
Calm felt spacer sleeves are designed to protect aluminum profiles during handling, stacking, storage, and transportation. The soft, cushioned felt helps absorb impact and reduce the risk of scratches, dents, and surface contamination.
The spacer sleeve also creates a small gap between profiles, allowing better air circulation and heat dissipation during cooling, handling, and stacking.
Made from high-quality heat-resistant industrial felt, Calm spacer sleeves are available in Nomex and Polyester and can be customized to meet different temperature and dimensional requirements. Multiple colors are available for easy identification and sorting.

Frequently Asked Questions
Reduce impact and the risk of profile damage during handling and heat treatment.
Separate aluminum profiles to improve cooling and ventilation.
Help prevent scratches, dents, and surface contamination during stacking, storage, and transportation.
Provide cushioning and separation for other metals and alloys in addition to aluminum.
Calm offers multiple colors to help customers identify different operating temperatures, materials, or finished products. Color coding can make sorting, handling, shipping, and delivery more efficient.
Yes. Nomex felt spacer sleeves can withstand temperatures of up to 280°C, making them suitable for aluminum aging applications where furnace temperatures are typically around 200°C.
Calm spacer sleeves provide a combination of cushioning, heat resistance, and reusability. The felt can provide a degree of thermal shrinkage as temperature increases, helping the sleeve maintain close contact with the aluminum profile and provide consistent protection.
With proper handling and maintenance, the sleeves can be reused, helping reduce replacement frequency and operating costs.
No. Calm spacer sleeves are manufactured using professional cutting and sewing techniques. The clean edges, uniform surface, and reinforced construction help provide reliable performance during repeated handling and use.
The cushioning performance of felt gradually decreases with prolonged use. We recommend regularly checking the sleeves for wear, deformation, contamination, or damage and replacing them when necessary.
Proper inspection and timely replacement help maintain consistent protection for aluminum profiles.
