Common Types of Wooden Formwork in Construction: Differences and Features

In the realm of construction, formwork is an essential material that can significantly affect both budget and project timelines. Among the various types of formwork available, wooden formwork stands out as the most commonly used option. In this article, we will explore the mainstream wooden formworks available in the market and their distinct characteristics.

1. Red Surface Wooden Formwork

The red surface wooden formwork is one of the earliest forms of formwork utilized in construction. Its defining feature is the red melamine waterproof glue on its surface, while the core is made of various types of wood including poplar, pine, or eucalyptus. Thanks to its lightweight properties, this type of formwork is convenient to use and is typically applied in underground structures, factories, or ground-level construction projects. 

2. Phenolic Mirror Wooden Formwork

Upgrading from the traditional red surface wooden formwork, the phenolic mirror wooden formwork offers superior quality. This product is manufactured under stringent standards, with a focus on having drier core materials. Its production involves a longer cycle and utilizes a two-time heat pressing technique. The surface boasts a high-quality phenolic resin, resulting in a smoother finish that facilitates easy demolding. Its mirror-like surface gives this template its name and is particularly advantageous for projects requiring high aesthetic finishes.

3. Film-Faced Wooden Formwork

Among the three types of wooden formwork, the film-faced wooden formwork is regarded as the highest quality option. It consists of a good-grade engineered board that is layered with a film paper, which is then heat-pressed with the board. The surface is treated with a film-facing technology, typically in black or red, composed of special adhesives. This type offers a smooth, glossy, and water-resistant surface that is remarkably durable, exhibiting excellent weather resistance, corrosion resistance, and chemical resistance. 

The film-faced wooden formwork not only enhances the smoothness of the cement surface but also ensures efficient demolding, preventing secondary spillage. This leads to significant improvements in work efficiency, saving both labor and material costs. Importantly, it does not pollute the construction site and aids in strictly controlling the emission of harmful gases.

In conclusion, when selecting wooden formwork for your construction projects, understanding the differences in their properties can lead to more informed decisions that save costs and time. The three main types—red surface wooden formwork, phenolic mirror wooden formwork, and film-faced wooden formwork—each serve unique functions and offer various benefits. By choosing the right type of wooden formwork, you can ensure a more efficient construction process that meets your project’s needs.
