FROM OUR EXPERIENCE
In our experience with residential and commercial builds, wall and ceiling damage is almost always preventable — and almost always the result of under-planning the containment system, not bad luck. The risk zones are predictable, the solutions are well-established, and the cost of getting it right is a small fraction of the cost of repairing damage after the fact.
Every golfer mishits. Tour professionals mishit in practice. In an outdoor setting, errant shots are self-resolving. In an enclosed simulator bay, they hit something — and that something is either a properly designed containment system or an unprotected wall, fixture, or person. Planning your containment correctly before installation is the most cost-effective approach.
Understanding the Risk Zones
Errant shots don’t go just anywhere. They follow predictable patterns based on swing mechanics — and each pattern threatens a specific area of the bay. Understanding the three risk zones is the foundation of every protection decision.

The overhead zone
Steep mishits — thin shots, steep downswings, or practice swings that contact the tee — send the ball upward at steep angles. According to ball flight physics (documented in the USGA’s technical equipment testing standards), a ball struck at a steep upward angle and full speed can travel 15–20 feet vertically before losing significant velocity. In a 9-foot ceiling room, this means overhead hardware, lighting, and structural elements are at real risk from severe mishits.
The side walls
Significant hooks and pushes are the primary side wall risk. For a right-handed golfer, a hard hook travels left; a severe push travels right. The highest-risk side wall zone runs from the hitting position to the screen, at approximately floor-to-6-foot height. High-handicap golfers and beginners have more severe and frequent side-wall shots than experienced players — something to factor into your protection planning if multiple skill levels will use the bay.
The wall behind the screen
Even well-aimed shots transmit force through the screen to the wall behind it. Over hundreds of sessions, this accumulated transmitted force creates surface damage to drywall or plaster even when no ball directly contacts the wall. In commercial settings with high shot volumes, wall damage behind unprotected screens is a predictable and consistent maintenance issue.
The Impact Screen: Primary Defense
A properly sized and properly tensioned screen is the first and most important containment system. If the screen captures essentially all intentional shots — including moderate hooks and pushes within normal variation — the downstream risk is significantly reduced. Undersizing the screen is a common planning error that leaves unprotected wall exposure on the sides of the frame.
Screen quality and proper tensioning are equally important here. A loose or worn screen lets balls rebound unpredictably and can fail outright at the worst moment. For a deeper look at what makes a good screen and how long it should last, see our companion guides on what makes a good golf simulator impact screen and how long a golf simulator screen lasts.
TruBack™ Performance Backer: Wall Protection
TruSim’s TruBack™ mounts between the primary screen and the wall, absorbing residual impact energy and protecting the wall surface. It also reduces ball rebound velocity — a meaningful safety benefit. Based on our engineering analysis and customer feedback, TruBack™ reduces transmitted impact force to the wall by approximately 40–60% under typical hitting conditions. In finished rooms, this protection prevents hundreds of dollars in drywall repair over the lifetime of the build.
TruGuard™ Overhead Mesh: Ceiling Protection
TruGuard™ installs across the ceiling of the bay, mounted to the truss structure above the hitting area. It provides a physical containment barrier against upward shots. In commercial facilities with public occupancy, overhead containment may be a code requirement — both under the International Building Code’s provisions for assembly occupancies and under local fire marshal requirements for containment of projectiles in public entertainment spaces.
Side Containment: Performance Drapes and Netting
TruSim’s Performance Drapes provide soft-surface containment for errant side shots while simultaneously managing ambient light in the projection zone. For commercial settings or high-traffic residential builds, dedicated side netting provides more robust containment for severe mishits. The netting catches and contains even extreme off-line shots without transferring significant energy to the structure behind it.
Layout: The Free Safety Measure
Correct bay layout is the most fundamental safety measure and costs nothing beyond planning time. The golfer should be centered in the bay with adequate clearance on all sides. The hitting position should never be adjacent to a door opening or a pathway. A clear protocol in shared spaces — no one stands ahead of or beside the golfer during a swing — should be established and consistently enforced.

Frequently Asked Questions
Do I need overhead containment if my projector is ceiling-mounted in the bay?
Yes — more so, in fact. A ceiling-mounted projector directly in the overhead risk zone should be protected by TruGuard™ mesh. Projector repairs or replacements from ball strikes are expensive and entirely preventable.
Is TruBack™ necessary if my screen is mounted close to the wall?
Yes — particularly in that case. When the screen is mounted close to the wall, transmitted impact force has nowhere to dissipate before reaching the wall surface. TruBack™ provides the energy absorption layer that prevents this concentrated force from damaging the wall.
What’s the most common overlooked protection area in residential builds?
The ceiling, consistently. Homeowners plan carefully for the screen and side walls but underestimate how often steep mishits and practice swings go upward. If your ceiling has any exposed hardware, lighting, or HVAC components, TruGuard™ is not optional.
