Idelite Chemical Resistant is highly resistant to most of the chemicals used today and will not crack, chip, peel, rust, rot or decay. Due to its lighter weight FRP requires less costly construction equipment needed to complete the job.
Fibreglass has become the product of choice for numerous industries. Chemical resistance sheet is used in the chemical, mining, mineral processing, pulp & paper and power industries in a wide variety of applications such as:

  • Flue gas desulphurization scrubbers and absorption towers
  • Stack liners
  • Ventilation and duct systems
  • Cooling water transmission
  • Waste water containment
  • Excellent corrosion resistant from all kind of alkali, acid, chemical fumes coastal environment, water and extremes of weather and temperature.
  • Superior tensile strength – FRP sheets have very high tensile strength to weight ratio
  • Chemical resistant to most fumes of hydrochloric acid, sulphuric acid and chloride salts.


  • To allow the natural linear thermal expansion of the sheet, the drilled hole should be at least 1.5 times the diameter of the mounting screw, and a rubber washer should be utilized in between.
  • The sheets should be screwed to purlins with fasteners not exceeding 200mm centers.
  • Vinyl Lap seal or mastic must be used between when fastening to steel.


IDELITE Walk On sheets should be cleaned with warm water regularly to remove obstructions to light transmission.

Health and safety:

Please note that all skylights should be considered fragile prior to installation. Even though IDELITE Walk On sheets have been designed for pedestrian traffic, walking on the sheet may result in the UV protective film being damaged which can degrade the sheet’s mechanical properties, therefore walking on the sheet is not recommended.

Material handling and storage:

Store sheets on flat, clean, level pallets with supports at 1.5m centers and do not stack the sheets over 1m in height. When sheets are stored outdoors, always cover them with an opaque, waterproof cover. Failure to do so can result in sheet discoloration due to boiling of entrapped moisture.
