Ceramic fiber blanket insulation can technically be used in residential buildings, but it may not be the best choice in many cases. Here are a few things to consider:

Safety

Ceramic fibers can cause irritation if inhaled and fibers must not be released during installation or repair work. This requires proper protective equipment and containment procedures.

Temperature needs

Most residential construction does not involve the very high continuous heat exposures (over 1000°F) that ceramic fiber is designed to withstand long-term. Alternative insulations may suffice.

Cost

Ceramic fiber blankets can be more expensive than common residential options like fiberglass and cellulose. The cost may not be justified in typical home applications.

Installation challenges

It requires specialized techniques and materials to properly contain ceramic fibers during installation in walls and attics. Professional installation is recommended.

Moisture resistance

Ceramic fiber performs well in damp and wet industrial environments but alternatives like mineral wool may integrate better with residential building envelopes.

However, it could be appropriate in niche high-temperature residential uses like masonry heaters, commercial kitchens, furnace areas, etc. where extra heat resistance is truly needed. Proper safety precautions are essential given potential health hazards if fibers are released.
