What is Formply and Why is it Important in Construction?

Formply is a type of plywood specifically designed for construction purposes. It is made by layering multiple sheets of wood veneer and bonding them together with a strong adhesive called phenolic resin. What sets high-quality formply apart is its special surface layer known as High-Density Overlay (HDO), which is also made with phenolic resin. This HDO layer gives formply its smooth and durable finish.

The Composition of Formply

Formply is made up of several key components:

• Cross-laminated wood veneers (usually 7-13 layers)
• Phenolic resin adhesive used between the layers
• HDO surface coating applied to both sides
• Sealed edges to prevent moisture from entering
