Alsina Phenolic Plywood
Alsina’s plywood board is made completely with birch wood having following the strictest quality controls. Its structure is made up of birch sheets glued to each other and protected on the outside faces with a phenolic film covering. The final assembly provides a stable, clean and resistant surface for our formwork systems.
For the manufacture, we took advantage of the fact that wood is a renewable resource, biodegradable, recyclable and does not pollute the environment. The birch wood, which is used for the sheets that make up the phenolic resin-coated plywood board, comes from forests with controlled logging.
The plywood board is formed by a series of wood counterlaid layers, glued and pressed together.This type of manufacturing, together with the phenolic layer on their outside faces, makes the phenolic board resistant, light and insulated against humidity. The number of internal layers will increase according to the thickness of the board.
The phenolic board, unlike sheet metal, does not dent, rust or leave marks on the concrete; it produces an excellent fair-faced concrete finish. Depending on it is treated by the workers on site, the number of times it can be reused can be increased considerably and with this, its cost-effectiveness is increased.
