Let’s be honest: it can be very hard to know exactly what grade or type of plywood is most adequate for any given type of construction project unless you are familiar with all the options at your disposal, including the labels on said types of plywood (which can be confusing). Some plywoods are lighter, cheaper, more durable, and more weather-resistant than others (not to mention more aesthetically pleasing).
Furthermore, the best type of plywood for building an outdoor project like a porch or deck may not necessarily be the most effective plywood for an indoor project like flooring or cabinets. Other projects like a boat hull, a shed, or a treehouse may also require other types of plywood.
So what is IS 710 grade plywood?
IS 710 is grading or specification that stands for marine grade plywoods. Don't get confused! Marine-grade plywood is much stronger than both MR and BWR grade plywood. ( MR stands for moisture-resistant and BWR stands for Boiling water resistant which is lower than BWP meaning Boiling waterproof ). It also has superior waterproof quality.
This can be gauged from the fact that Marine plywood can be submerged in water for 72 hours without any kind of damage. Phenol formaldehyde resin is used for bonding the piles of veneer in marine plywood. Marine-grade plywood is mostly used for making ships and boats. It is also exterior grade plywood designed to withstand extreme weather conditions.
Common Plywood Grades in the market - IS 303 & IS 710.
How do we differentiate these?
303 plywoods are water-resistant and not waterproof. Such plywoods can withstand only a certain level of humidity and dampness. 710 plywoods, on the other hand, are completely waterproof as they are tailor-made for marine applications.
Diluted Urea Formaldehyde resin or Phenol Formaldehyde resin is used to bond the veneers in 303 plywoods. On the other hand, undiluted Phenol Formaldehyde resin is used to bond the veneers in the case of 710 plywoods. This synthetic plastic resin enhances the waterproofing quality of 710 plywood. 710 plywood is better external grade plywood as compared to BWR plywood coming under 303-grade plywood. 710 grade plywood are tough enough to be used for marine applications such as building ships and boats.
