If you think mould, fungus and termite are the problems to the nesting planks then you may want to consider the cement board as nesting planks.
For me I would stick to my 100% pure Dark Re Meranti. For those who can’t get the Dar red Meranti even they pay premium price then cement board would be the next option.
The installation works for the cement board is not easy but for sure one thing it could solve all those mould problems and gap between ceiling and planks is history.
The picture shows a beautifully done nesting plank with cement board.
Having this picture shown those who want to install them would have some idea.
Good Farming All!
