Architectural fashions come and go over the years.
One day it is perforated mesh, the next louvers, but the latest trend seems to be with timber infilled gates.
This particular type! Tracked sliding gate is for a supermarket service yard, entrance and exit.
Architects like this style and finish as it solves multiple site issues. You can see into the yard, it has sound deadening properties and it still looks good.
The major problem comes in when the architect specifies a particular type of wood. This is not necessary, is hard to get hold of, and more expensive than other more practical woods. Wood from B&Q is easier to get hold of, rather than the amazon rain forest.
