Understanding the Difference Between Shuttering Ply and Regular Plywood

Plywood is a staple in construction and is used across various applications, from furniture to formwork. However, not all plywood is the same. One of the most common distinctions in construction is between shuttering plywood (shuttering ply) and regular plywood.

While both are made from layers of wood veneer bonded together, their intended use, durability, and performance vary significantly. Choosing the correct type of plywood for builders, contractors, and engineers can dramatically impact project costs, sustainability, and overall efficiency.

This blog breaks down the key differences between shuttering ply and regular plywood, along with a modern alternative transforming the industry—plastic shuttering sheets.

1. What is Regular Plywood?

Regular plywood is a multi-purpose wood panel used extensively in furniture, interior décor, partitions, and general construction. It comes in different grades, such as:

  • MR Grade (Moisture Resistant) – Used for interior applications like wardrobes and cabinets.
  • BWR/BWP Grade (Boiling Water Resistant / Boiling Water Proof) – Used in kitchens, bathrooms, and exterior applications with higher moisture exposure.

Regular plywood is not designed to withstand heavy loads or prolonged exposure to water, making it unsuitable for formwork applications.

2. What is Shuttering Plywood?

Shuttering plywood (also called formwork plywood) is engineered specifically for concrete moulding. It is made with high-density wood veneers bonded with waterproof adhesive and is further treated to withstand moisture, concrete pressure, and rough handling at construction sites.

Shuttering ply is commonly used in:

  • Column and beam formwork
  • Slab and wall formwork
  • Bridge and dam construction

It is built for strength and durability, but it can be reused only a limited number of times before it starts to warp, swell, or delaminate.

Alternative Available?NoYes – Plastic Shuttering Sheets

4. The Problem with Shuttering Plywood

While shuttering plywood has been the go-to choice for decades, it comes with serious limitations:

1. Limited Reusability

Even high-quality shuttering ply offers only around 10 repetitions before it becomes unusable. This leads to frequent replacements, increasing long-term costs.

2. Prone to Warping and Swelling

Despite being water-resistant, shuttering plywood absorbs moisture over time, leading to warping, swelling, and surface defects. This results in uneven concrete finishes and wastage.

3. Environmental Concerns

Shuttering plywood contributes to deforestation. Large quantities of wood are harvested to produce formwork ply, which has a short lifespan. Additionally, discarded plywood contributes to construction waste.

4. High Long-term Costs

Since plywood deteriorates quickly, builders spend more on replacements over time. The hidden costs of frequent purchases, transportation, and disposal make plywood an expensive long-term choice.

5. The Future: Plastic Shuttering Sheets

Builders are now switching to plastic shuttering boards as a sustainable, durable, and cost-effective alternative to plywood.

What Are Plastic Shuttering Sheets?

Plastic shuttering sheets (such as WoWBoards) are made from recycled plastic materials, offering superior performance compared to traditional shuttering plywood.

6. Why Plastic Shuttering Boards Are Better

FeatureShuttering PlywoodPlastic Shuttering Sheets
Reusability~10 repetitions50+ repetitions
Water ResistanceLimited100% Waterproof
Termite ResistanceProne to termite damageTermite-proof
Warping & SwellingWarps and swells over timeRetains shape
Finish on ConcreteCan leave imperfectionsSmooth finish
Environmental ImpactTree cutting, high wasteMade from recycled plastics
Cost Over TimeFrequent replacementsLong-term savings

How Builders Benefit from Plastic Shuttering Sheets

  • Cost-Effective – Higher upfront cost but significant savings due to reusability.
  • More Repetitions50+ reuses compared to plywood’s 10 repetitions.
  • Sustainability – Made from recycled plastic, preventing waste from reaching landfills.
  • Stronger & More Durable – Resistant to moisture, termites, and harsh site conditions.

7. Making the Switch: A Smart Move for Builders

If you are a contractor, builder, or engineer looking to reduce costs while improving efficiency, plastic shuttering boards are the future of formwork. They solve every issue faced with plywood while helping construction projects become more eco-friendly.

Why Wait? Make the Switch Today!

Recycled plastic sheets and boards offer the best alternative to shuttering plywood—long-lasting, sustainable, and built for the toughest construction conditions.

While regular plywood has its place in furniture and interiors, shuttering plywood is designed for short-term construction use. However, its high cost, short lifespan, and environmental impact make it a poor long-term choice.

Plastic shuttering sheets (WoWBoards) are the ultimate alternative, offering durability, sustainability, and cost savings. The construction industry is evolving—are you ready to grow with it?
