Prescribed Expansion Gaps

Manufacturers meticulously design composite decking with prescribed expansion gaps. These calculated spaces allow the material to expand and contract with changing temperatures without causing damage or structural issues.

A typical deck might require a gap of 1/8 inch between boards for optimal performance. Ignoring these specifications could lead to warped boards, buckling, or other serious problems over time.

Always pay close attention to the manufacturer’s guidelines when installing your deck to ensure longevity and beauty in every season.

Measuring Expansion: What to Expect

Composite decking is known for its tendency to expand and contract due to changes in temperature. But what does that actually mean for your deck? Well, expect some movement. As the temperature fluctuates, composite decking can expand or contract by a small amount.

This expansion is typically minimal and within an acceptable range. However, it’s important to keep in mind that different brands may recommend different gap sizes between boards to accommodate for this expansion.

Additionally, pure PVC decking tends to have less noticeable expansion compared to composite decking with a mineral-based core. So, when it comes to measuring expansion, don’t be alarmed by a little movement – it’s just part of the nature of composite decking.

Brand Variations in Gap Recommendations

When it comes to the world of composite decking, each brand has a unique set of gap recommendations based on their product design and materials. To give you a clearer picture, below is a comparative table showcasing the gap recommendations of leading brands in the industry.
