Armstrong 705 Fissured Tile

This Armstrong 705 tile is a mineral-fiber panel with a medium fissured texture and an angled tegular edge. It is sold in a pack of 16 pieces covering 64 sq ft. The white finish suits general-use ceilings in offices, schools or retail spaces that need basic acoustic control and a clean appearance.

Practical limits of the 15/16 in grid

The tile fits a standard 15/16 in suspension grid and is 5/8 in thick. Its Noise Reduction Coefficient is 0.55 and its Ceiling Attenuation Class is 30, so it reduces reverberation but does not block loud speech or mechanical noise between rooms. Light reflectance is 0.81, helping to spread ambient illumination. It is rated for temperatures from 32 to 120 degrees F and meets Class A fire-retardant requirements under ASTM E1264.

Installation notes and common issues

Panels lay into the grid without clips, making placement straightforward for a single installer. The fissured surface can show fingerprints, so clean gloves are recommended during handling. Cutting the mineral fiber creates dust; a utility knife and a dust mask are standard practice. The pack weighs 43.53 lb, so plan for safe lifting and storage before the job starts.

Questions about this item

Which Armstrong 705 pack covers my 24 by 24 grid?

Each carton contains 16 tiles measuring 24 in by 24 in, giving 64 sq ft total coverage for a standard 15/16 in grid.

What does the 0.55 NRC mean once the tiles are installed?

A Noise Reduction Coefficient of 0.55 indicates the tiles absorb 55 percent of incident sound energy, reducing echo in offices or classrooms.

How does the 15/16 in grid size limit the layout?

The tiles are cut for a 15/16 in exposed tee grid; they will not fit narrower 9/16 in or wider grid profiles without modification.
