Expansion Joint Ceramic Fiber Felt 1260C For Low Thermal Conductivity Service

Low Thermal Conductivity Flexible Installation Lightweight Ceramic Fiber Felt

This low thermal conductivity ceramic fiber felt is a thin, dense insulation made from high-purity ceramic fiber. Because it is thinner and denser than a blanket, it gives a low, even thickness with a low thermal conductivity, which suits gaskets, seals and tight spaces where space is limited but insulation is still needed. The felt is lightweight, flexible and A1 non-combustible, and it stays stable through repeated thermal cycling.

Flexible installation is easy: the felt is cut with scissors or a blade and wrapped or laid tightly to any shape, held in place by a low organic binder or a mechanical fixing. It is a practical choice for gaskets, expansion-joint packing, back-up insulation in confined spaces and thin heat barriers in appliances and equipment. Tell us your thickness and duty and we will recommend the right felt grade.

Supply and Service

All our ceramic fiber products are manufactured from high-purity ceramic fiber and are supplied rolled, boxed or packed on pallets for easy handling, transport and storage; they should be stored indoors or under a waterproof covering. Every batch is checked for density, thermal conductivity and dimensional accuracy before dispatch. Our products are also available in additional densities, thicknesses, widths and facings, including aluminium foil facing for blankets, so please tell us your working temperature, atmosphere and fixing method and we will match the specification to your line. Samples and test reports are available on request for approval before ordering. If you would like a full technical data sheet, a free sample, the applicable test report or a project quotation, our engineering team is ready to help you select the right grade, thickness and finish for your furnace, kiln, boiler or high-temperature line. Tell us your working temperature and application and we will recommend the most cost-effective solution.

Frequently Asked Questions

Q: How is felt different from blanket?

A: Felt is thinner and denser than blanket, so it suits gaskets, seals and tight spaces where a low, even thickness is needed.

Q: Does it have a binder?

A: Standard felt uses a low organic binder and binder-free options are available for very clean furnace duties.

Q: Can it be cut easily?

A: Yes. Felt is flexible and cuts cleanly with scissors or a blade to fit any shape.
