Versatility of HPL Panels: A Guide on Shape, Size, and Installation
| Last updated August 26, 2025
Versatility is a large part of the appeal of phenolic, also known as high-pressure pressure laminate (HPL), paneling. The material is reliable, durable, and can give contractors great flexibility while providing high design quality.
By partnering with Fundermax, contractors also enjoy increased freedom to buy what they need, how they want it made.
Our contractor customers appreciate that they can buy Fundermax directly without being forced into a third-party chain that, in some instances, may compete with them on the installation.
With Fundermax, qualified contractors with the proper equipment are able to buy phenolic panel sheets through either direct sale or one of our national distributors. Contractors and architects alike can utilize our local representative network to connect end users to Fundermax on the best way to purchase our materials.
Additionally, we give contractors the opportunity to source their panel mounting systems from several approved domestic sources. Regardless of what our competitors may promise, no one else manufacturing phenolic panels also manufacture the sub-framing systems.
By opening up and separating the two, we allow more competitive pricing and avoid an extra layer of needless mark-up on extrusions and shop drawings.
For those contractors who do need a complete system ready to install, we also offer fully engineered packages including shop drawings from one of our National Package Resellers.
Buying from Fundermax can also be more efficient as we have a state-of-the-art CNC processing facility in Austria. This allows us to offer panels cut to size or custom machining of perforated patterns and designs.
What Are The Different Phenolic Panel Fastening Systems?
Fundermax also provides phenolic panels with different fastening systems available to suit a wide variety of interior or exterior applications.
Our exterior panels are manufactured to be incorporated into the façade mounting systems.
Exposed Fastening System
The exposed fastening system employs Max Compact Exterior façade panels along with color-coordinated screws or rivets, offering extensive design flexibility at a cost-effective price for constructing your back-ventilated rainscreen façade, soffit, or various other outdoor applications. The color-coordinated fasteners secure the panels to the aluminum or wood sub-framing, seamlessly integrating into the façade. Additionally, the choice of polished or black exposed fasteners is available, imparting a more industrial aesthetic to your exterior design.
Concealed Fastening System
The concealed fastening system allows façade panels to be attached with invisible fasteners. It employs anchors embedded in the rear of the Max Compact Exterior panel, which are suspended on horizontal rails connected to vertical wall brackets, creating a fully back-ventilated NFPA 285 compliant rainscreen system. This approach provides designers with extensive design flexibility without visible fastening points.
Modulo Plank Fastening System
Our Modulo Plank system, shown to the left, is prefabricated with Max Compact Exterior façade panels and provides a durable and modern look for commercial as well as residential buildings. This closed joint modern façade plank system has concealed fasteners. This makes it possible to install the prefabricated planks (with length options up to 161 inches) without any open joints. Plus, our FastMax Program expedites the shipping process of Max Compact Exterior panels with Modulo fastening systems.
Scaleo Lap Siding Fastening System
Our Scaleo Lap Siding system is another prefabricated system primarily used in residential applications. The system is straightforward to design and implement, delivering a robust and contemporary façade with more than 100 décor options in double-sided balanced panels that require minimal maintenance and are easy to clean.
Fundermax abrasion, impact, UV, and weather resistant panels are available in five different sizes, fitting a number of different envisioned designs and projects.
This design flexibility combined with competitive pricing and convenience can make a big difference to user satisfaction and installer budgets and timelines.
