STi NP45 Artificial Grass
Synthetic Turf International (STI) NP45 is a commercial-grade, texturized nylon artificial turf designed primarily as a high-performance golf putting green surface and premium golf simulator flooring. Positioned as an accessible, high-utility mid-tier offering just below STI’s flagship NP50 and NP55 lines, it is widely celebrated for its ability to deliver an exceptionally true roll without requiring sand or rubber infill underfoot. It is one of the industry's most common selections for main-floor golf simulator surfacing. Because it functions perfectly without infill, it prevents loose debris from kicking up into expensive simulator optics while acting as a deadening catchment area that minimizes ball bounce and roll off the impact screen. Popular for smaller backyard custom builds. Its nylon composition guarantees that the turf does not expand or contract noticeably under intense direct sunlight, keeping the putting plane perfectly stable year-round. Because it lies perfectly flat when unrolled and can be applied directly onto concrete or interlocking panels without top-dressing, it is frequently cut into premium, transportable putting mats.

Built For Natural Landscape Performance
Synthetic Turf International (STI) NP45 is a highly adaptive, commercial-grade texturized nylon turf designed specifically for high-performance sports and recreation layouts. Because it features a dense, texturized 100% nylon fiber matrix, it does not require sand infill to remain upright. Because it is completely non-infilled, it eliminates loose sand or rubber dust from kicking up and damaging expensive tracking cameras, radar units, or projector lenses. The dense 3/8-inch nylon pile absorbs clubhead impacts and deadens the bounce of golf balls dropping down from the impact screen, preventing them from violently ricocheting back at the golfer. It serves as a continuous putting floor that seamlessly surrounds modular hitting strips (like the STI EZTee Hybrid), creating a flush, professional aesthetic across the entire simulator room. It yields a consistent, non-directional ball tracking speed averaging 10.5 on the Stimpmeter without any heavy sand top-dressing. Unlike polyethylene landscape turfs, nylon has incredibly high thermal resistance. It resists stretching, expanding, or buckling under the intense direct heat of outdoor summer sun.

Recommended Applications
Synthetic Turf International (STI) NP45 is a commercial-grade, 100% texturized nylon turf used primarily for high-performance putting greens, indoor golf simulators, and commercial agility tracks. Because its dense nylon fibers naturally stand upright without the help of messy rubber or heavy sand infill, it is a premier choice for indoor clean-room environments and high-heat outdoor applications. The zero-infill design prevents fine sand or rubber dust from kicking up, which protects expensive tracking cameras, high-speed radar units, and projector lenses from static damage. The tight nylon weave absorbs the impact of golf balls dropping from the projection screen, preventing them from violently bouncing back into the hitting area. It serves as a smooth walking and putting floor that seamlessly surrounds modular hitting mats, creating a flat, uniform surface from the screen to the tee box.

Installation & Care Notes
Synthetic Turf International (STI) NP45 installation applications depend on whether the project is indoor (golf simulator or commercial gym) or outdoor (backyard putting green). Because NP45 is a high-density, texturized 100% nylon turf, it reacts differently to temperature changes than standard polyethylene turf. It expands and contracts slightly with moisture rather than heat, requiring precise stretching, anchoring, and adhesive techniques to ensure a perfectly flat, wrinkle-free surface. The underlying concrete must be completely cured (minimum 28 days), level, and free of cracks, dust, or oils. Any low spots are patched with a self-leveling compound. A high-tack, low-VOC exterior polyurethane or acrylic turf adhesive is spread over the concrete using a 1/8" x 1/8" x 1/8" square-notched trowel. Once the turf is relaxed and laid into the wet glue, a 100-pound water-filled or steel roller is run across the entire surface. This eliminates air bubbles and guarantees a flush bond, preventing the turf from bubbling when heavy weight sleds or dragging feet pass over it.
- Professional base preparation recommended
- Use appropriate infill for the application
- Brush fibers periodically to maintain appearance
- Rinse as needed for dust, pets, or debris
- Confirm drainage needs before installation
Warranty & Availability
Synthetic Turf International (STI) provides an 8-year limited manufacturer warranty on STI NP45 putting green turf. This factory product warranty covers manufacturing defects, premature face fiber degradation, and excessive UV color fading or tensile strength loss under normal use. Protection against unusual or excessive color fading caused by ultraviolet light exposure, ensuring the putting green retains its deep green aesthetic. Covers structural delamination, where the secondary backing material splits away from the primary tufted yarn canvas. Guarantees that individual yarn loops or blades will not pull away or shed from the backing under standard foot traffic and putting practice. Using non-approved, water-based carpet glues indoors or failing to establish a stable, compacted 3-to-4 inch crushed aggregate sub-base outdoors.

Is STi NP45 Right For Your Project?
Synthetic Turf International (STI) NP45 is primarily used for indoor golf simulators, backyard putting greens, and portable golf training mats.Because it is engineered from a high-density, texturized 100% nylon fiber system, it offers a highly consistent, true ball roll that closely replicates country club green speeds (averaging a 10.5 Stimp rating). Its unique advantage is versatility; it performs excellently with a premium ceramic infill outdoors but functions completely sand-free indoors, making it a staple for premium recreational and athletic spaces. NP45 is a dominant industry choice for indoor simulator bays. Because it functions perfectly without infill, it provides a clean, mess-free floor that acts as a ball collection area. It catches shots coming off the impact screen, deadens the bounce, and allows players to practice realistic putting on the exact same surface. Homeowners frequently integrate STI NP45 into luxury backyard oases.
