• Retains superior properties even in infrequently heated and unheated rooms.

• Precautions should be taken to avoid condensation risks.

• In accordance with BS EN 13964, predominantly classified as class 1/C/0N. Certain module sizes are class 2/C/0N.

Cleaning:

• Vacuum: The surface can be vacuum cleaned with soft brush attachment.

• Damp cloth: The surface can be cleaned with wet cloth or sponge with a slightly alkaline detergent (pH between 7 and 9) without alcohol, ammonia or chlorine (this may render the surface slightly shinier, so a thorough clean is recommended).

• May also be foam cleaned up to 52 times a year by spraying foam onto the surface and wiping off.

• High pressure cleaning, up to 52 times a year. Where high pressure cleaning is required the Hygienic tiles can be clipped into the grid and sealed with a silicone sealant containing fungicide.

Hygiene:

Stone wool is an inorganic material which is not attacked by rot, fungi or bacteria. This makes for a cleaner and healthier indoor environment.
