Installation Guide

Before You Begin
■ Store and install ceilings in areas with a temperature range of 60° to 85° F
and not more than 70% relative humidity.
■ Remove ceiling tile from cartons 24 hours before installation and allow to
adjust to normal interior conditions of the installation area.
■ Do not apply loose fill or batt insulation so that it rests directly on the back
of the tiles.
■ Do not install ceiling tiles below imbedded radiant-heat coils.
■ Keep hands clean during tile installation to avoid fingerprints and smudges.
■ Handle ceiling tiles carefully to protect the face and edges from damage.
■ Always cut ceiling tiles face up with a sharp utility knife.
■ For Adhesive Applications of mineral fiber only
tiles directly to existing
drywall or plaster ceilings: Ceiling tile adhesive recommended, such as
Henry #237B Acoustical Adhesive. Please follow adhesive manufacturer’s
instructions for application and usage. Armstrong does not guarantee the
performance of this or other adhesive products, either alone or in
conjunction with Armstrong products.
