7. Frequently Asked Questions on Wood Sports Flooring (with Technical Jargon Explained)
Q1. What is "keel structure" in sports flooring?
"Keel structure" refers to the engineered wooden battens (usually spruce) arranged orthogonally beneath the wear layer. Double-layer keels enhance shock absorption, stability, and even load distribution, minimizing dead spots during play.
Q2. How is slip resistance measured and why is "COF" important?
COF (Coefficient of Friction) quantifies slip safety. Wood sports flooring for FIBA/EN 14904 use requires COF between 0.5–0.7—measured via pendulum or tribometer testing—to ensure player safety during dynamic movement.
Q3. Why is North American Maple preferred for sports flooring?
North American Hard Maple offers uniform grain, high density (700 kg/m³), high abrasion resistance (Taber test ≥ 10,000 cycles), and exceptional elasticity—ideal for sustained ball bounce and durability.
Q4. What are the main installation standards for wood sports floors?
Major criteria include substrate levelness (≤2mm/2m), humidity control (RH 35-65%), and adherence to EN 14904 / FIBA technical requirements for shock absorption, deformation, and ball rebound. Final certification typically involves third-party lab tests.
Q5. How does polyurethane UV coating benefit indoor sports flooring?
UV-cured polyurethane offers ultra-durable, low-VOC surface protection. It amplifies abrasion resistance, anti-slip properties, ease of sanitation, and allows for rapid curing with minimal emissions (compliant with EU Ecolabels).
Q6. What is the typical lead time for manufacturing and delivering a custom hardwood sports floor?
For the Double-layer keel structure, standard lead time is 28–40 days (ex-works) subject to project size, customization, and shipping. Expedited schedules available for institutional projects.
Q7. Does Enlio provide after-sales service and what is covered under warranty?
Yes. Enlio offers up to 10 years of warranty covering manufacturing defects, surface delamination, and structural failure. Support includes annual inspection, maintenance guidance, and parts replacement.
