Choosing the right mounting system for decorative wall panels is one of the most important specification decisions in a commercial fit-out. The wrong choice leads to visible fixings, limited maintenance access, or panels that cannot be updated without full removal. This guide compares the five main methods used by architects, interior designers, and commercial contractors, and explains when each is appropriate.
How different decorative wall panel fastenings compare in commercial settings
Fastmount
Fastmount first developed products for the marine and super yacht industry, developing attachment systems that address some of the limitations found in Z clips and other methods. Unlike Z clips, Fastmount systems don’t rely on a hanging method. Instead, their attachment system connects directly once the two parts (male and female) engage. This eliminates the need for a gap at the top of the panel and allows panels to be disassembled in non-sequential order.
The Stratlock® range from Fastmount includes an adjustability feature that simplifies the alignment process, making it an excellent solution for complex jobs by reducing rework and ensuring a perfect finish. They offer a wide range of clips for various panel types and weights, including fire-rated options for commercial and high-risk environments.
Fastmount clips are fully compatible with CNC machining. Clip positions can be programmed into CNC machines, allowing for precise pre-drilling of panels and substrates. This compatibility enhances efficiency in panel preparation and installation, especially for large-scale projects.
Like Z clips, when installing Fastmount clips on uneven walls, you can shim or pack them to ensure evenness. Installation typically involves tools like a laser level, template or the centre points provided by Fastmount.
Z Clips
Z clips have traditionally been used in the United States to attach decorative panels to walls, however commercial projects tend to expose their limitations.
In the case of complex designs, panels that need to fit at odd angles, walls that aren’t perfectly straight, or designs with a very tight gap control between panels, Z clips often require significant rework to achieve a clean result.
Two notable drawbacks of Z clips stem from their hanging mechanism. First, there’s always a visible gap at the top of the wall, which may not be aesthetically pleasing. The other issue is that if you want to replace or access a lower panel, you need to remove all the panels above it, which can be time-consuming and costly both in terms of labor and potential damage.
When installing Z clips on uneven walls, shimming (or packing) is often necessary to ensure the clips are straight. Installation typically requires tools like a laser level, story pole or template.
French Cleats
French cleats, also known as split battens, are particularly popular in Europe and Australia, but also have their limitations in commercial settings.
Similar to Z clips, the main differences lie in the material and profile. Despite French cleats being typically made of timber which can be crafted from leftover material, they often require more labor and time to prepare. Additionally, the gap between the panels and the wall is usually larger with French cleats due to the thicker profile of timber compared to the thin aluminum of Z clips.
Adhesives
Adhesives are another option for installing interior decorative wall panels, though their use in commercial projects is generally limited to lightweight, low-access applicationsThese drawbacks are more consequential in commercial settings, where rework and downtime carry higher cost. Once the adhesive cures, it’s extremely difficult to remove or adjust panels without causing damage. The installation process can be messy, and there are potential sustainability concerns to consider. Many adhesives contain harmful chemicals that can off-gas, impacting indoor air quality. Their production also often involves energy-intensive processes and non-renewable resources, raising environmental concerns. In some cases, you may even need an additional method to hold decorative panels in place while the adhesive cures. Adhesives can also fail in high-humidity environments, potentially leading to panel detachment. Once applied, there’s no room for adjustability, so precise placement is crucial.
Nails
Nails offer a straightforward method for attaching panels, but they’re visibility limits their use in commercial and other high end applications where aesthetics and practicality are crucial. They’re best suited for projects where visible attachments are acceptable, and quick, easy installation is prioritised over a seamless look.
Other less common methods for installing wall panels
Rail and channel systems: Rail and channel systems involve mounting a rail or channel to the wall and sliding the panels into place. This method is useful for large or heavy panels, but can have visible components that are not desired in some commercial settings.
Clips and brackets: These systems often involve mounting brackets to the wall and clipping the panels into place. They are usually secure and adjustable but installation can be complex, and often system-specific.
Double-sided Tape: This involves applying tape to the back of the panel and pressing it onto the wall. It’s a quick and simple method for attaching lightweight panels, but limited in its commercial application because of this.
Velcro Strips: This involves applying a strip to the wall and another to the panel and then joining them up. It’s an easy to apply method but it’s limited in its weight capacity, and may lose adhesion over time.
Magnetic Mounting: As the name suggests, this method involves the use of magnets to hold panels in place. Installation is simple but again, it’s only suitable for specific, lightweight panels.
Choosing an interior decorative wall panel mounting system for commercial projects
Selecting a mounting system for a commercial project involves weighing installation speed against long-term maintenance access, aesthetic requirements, and lifecycle cost. Fastmount is typically the right specification choice in the following scenarios:
- Hospitality fit-outs that require panels to be changed or refreshed regularly without disrupting operations.
- Healthcare and food service environments where panels need to be removed for cleaning and maintenance access behind the wall.
- Large-scale commercial projects where consistent alignment across many panels is critical to the finished result.
- High-end commercial, residential, and marine projects that require no visible fixings.
CNC compatibility is also a significant differentiator for millwork contractors and fabricators. Because Fastmount clip positions can be pre-programmed into CNC machines, panels and substrates can be pre-drilled in the workshop before delivery to site. This shifts precision work off-site, reduces on-site installation time, and minimizes the risk of alignment errors during fit-out, a meaningful advantage on large or fast-tracked commercial projects and minimizes the risk of alignment errors during fit-out.

Frequently asked questions
What are the best panel wall clips for different wall surfaces?
The right clip depends on the substrate. Drywall and plasterboard suit Fastmount’s Low Profile Range, which is engineered for thinner substrates. Plywood and wood-backed walls accommodate the Standard Range, offering higher pull out loads. Uneven, curved, or geometric substrates are best served by the Stratlock® Range, which offers adjustability to compensate for surface irregularities. See the substrate compatibility row in the comparison table below for a full breakdown by method.
What is the difference between Z clips and Fastmount for commercial wall panel installation?
Z clips rely on a hanging mechanism: panels hook onto a rail, which leaves a visible gap at the top of the installation and means panels can only be removed in sequence from the top down. Fastmount’s male and female clips engage directly, eliminating the top gap and allowing any panel to be removed independently, in any order, without disturbing surrounding panels. This makes Fastmount the preferred system for commercial projects that require ongoing maintenance access.
Can decorative wall panel clips be used with fabric-wrapped or upholstered panels?
Yes, Fastmount’s Textile Range is purpose-built for fabric-wrapped and upholstered panels, providing secure, hidden attachment that avoids the pressure points and visible hardware associated with traditional upholstery fasteners, while still allowing the panel to be removed for cleaning or replacement.
How do I install decorative wall panels step by step in a commercial project?
A typical Fastmount installation follows five steps:
(1) mark clip positions on the substrate using a layout guide or CNC-programmed template
(2) fix the female clips to the substrate
(3) fix the corresponding male clips to the back of the panel
(4) align the panel with the substrate and press firmly until the clips engage
(5) check alignment across all panels and adjust as needed before final fixing.
Because positions can be pre-programmed and pre-drilled off-site, this sequence is significantly faster on commercial projects than clip systems requiring on-site marking and adjustment.
