Why should expansion joints be left when installing WPC decks?

WPC decks that are not deformed or cracked, brightly colored and rock-solid, are increasingly appearing in outdoor landscapes such as balconies, courtyards and many parks and squares; careful friends will find that the horizontal and vertical end faces of the WPC decking are connected. There will always be gaps of about 3 mm. So, are these gaps for ventilation or for rainwater to leak?

When the temperature difference between morning and evening or winter and summer is too large, the wood-plastic deck will slightly expand and contract; installation The expansion joints reserved at the time are the space for the wood-plastic floor to move, so as to avoid the deformation and arching of the wood-plastic floor when the temperature difference is too large.
