WATERPROOF PLYWOOD

Borotik Waterproof Plywood is a range of plywood having varied rate of protection against moisture content & water. Based on water resistance, there are three grades of plywood specified by Bureau of Indian Standards (BIS). They are :

  • Moisture Resistant (MR)
  • Boiling Water Resistant (BWR)
  • Boiling Water Proof (BWP)
  • They are given in more detail in the table below.

    GRADETest DetailsPlywood StrengthGrade RatingApplicationIS Standard
    Moisture Resistant (MR) Six cycles with each cycle consisting of 8 h boiling in water and thereafter drying at 65 +/- 2⁰C for 16 h Withstand cold water for a long time and hot water for a limited time, but fail in boiling water. Interior grade plywood Interior use such as in furniture, cabinets, and shelves. IS 303-1989

    IS 1328-1996

    IS 848-2006
    Boiling Water Resistant (BWR) Three cycles with each cycle consisting of 8 h boiling in water and thereafter drying at 65 +/- 2⁰C for 16 h Withstand cold water indefinitely and boiling water for a limited time External grade plywood Mainly used as roofing material for external sheathing of the building. Also suited for bathroom and kitchen doors IS 303-1989

    IS 1328-1996

    IS 848-2006
    Boiling Water Proof (BWP) Three cycles with each cycle consisting of 3 h at 60 +/- 2⁰C in water and thereafter drying at 65 +/- 2⁰C for 8 h Highly resistant to weather, cold and boiling water, steam and dry heat Marine Grade plywood Mainly used in marine applications such as ships and boats IS 710-2010

    IS 848-2006

    Borotik manufactures high quality waterproof plywood as per Bureau of Indian Standards specifications (IS 710). This plywood is completely resistant to moisture and humidity. It is most appropriate for outdoor applications like boats and ships which are exposed to water for a prolonged duration. However they are also suited for kitchen or bathroom doors for the same reason. They exhibit high dimensional stability, strength and negligible warpage and distortion due to our unique wood seasoning technique. It is chemically treated to be termite and borer resistant.

    Features

    Advantages

  • Borotik chemical treatment and seasoning eliminates distortion, warping and maintains dimensional stability.
  • They are chemically treated to be impervious to termite, borer and fungi attack
  • They have high strength to weight ratio.
  • The plies act as crack arrestors which prevent crack propagation through the plies and substantially improve the service life of the plywood.
  • The panel shear strength of plywood is approximately twice that of solid wood. This is due to its cross ply or cross laminated structure. This makes it an indispensible material for structural applications.
