ImpactBoardFR vs Plywood – Which is Better for Temporary Protection?

Choosing the right temporary protection material can have a major impact on site safety, efficiency and sustainability. While plywood has long been a familiar option across construction projects, modern alternatives such as ImpactBoardFR are designed to overcome many of its limitations. From fire performance and moisture resistance to handling and reuse, understanding the differences between ImpactBoardFR and plywood can help contractors select the most effective solution for their project requirements.

Feature ImpactBoardFR Plywood
Material type Engineered fluted polypropylene Natural timber sheet
Fire rating Flame-retardant (FR compliant) Typically not fire-rated
Weight Lightweight Heavy
Handling Easy to cut, carry and install Requires more labour
Durability High impact resistance Strong but can splinter
Water resistance Fully waterproof Absorbs moisture, can warp
Reusability Designed for multiple uses Limited reuse depending on condition
Surface protection Non-abrasive Can mark finished surfaces
Sustainability Recyclable + ClosedLoop compatible Often single-use, harder to recycle
Consistency Uniform performance Variable quality

 

 

Key differences explained

Fire safety

ImpactBoardFR is manufactured to meet flame retardant standards, making it suitable for projects with strict fire compliance requirements (JCoP). Plywood, unless specially treated, does not offer the same level of fire performance.

Weight and installation

ImpactBoardFR is significantly lighter, which makes handling faster and safer on site. Plywood is heavy, often requiring more labour and time to install.

Moisture performance

ImpactBoardFR is fully waterproof and maintains its integrity in wet conditions. Plywood absorbs water, which can lead to swelling, warping, and reduced effectiveness.

 

Pros and cons of ImpactBoardFR

Pros Cons
Flame retardant Higher upfront cost
Lightweight and easy to handle May be over specified for low risk areas
Waterproof
Reusable
Recyclable
Consistent quality

 

Pros and cons of Plywood

Pros Cons
Strong and rigid Heavy and labour intensive
Widely available Not fire rated (standard grades)
Familiar on site Absorbs moisture
Lower initial cost Limited reuse
Can damage surfaces
