Innovative Design with Thermoformed ACRE
June 2025As architecture continues to evolve, so does the demand for materials that go beyond straight lines and right angles. Curved walls, rounded corners, arched trim, and sculptural facade treatments are no longer outliers—they are increasingly central to both residential and commercial design. Meeting this creative demand requires materials that are able to be thermoformed, are durable, sustainable, and easy to work with.
Thermoforming, a process that uses heat to shape materials into custom curves and profiles, makes this level of design flexibility possible. ACRE by Modern Mill is uniquely suited for thermoforming. Made from upcycled rice hulls and crafted to replicate the look and feel of real wood, ACRE can be heated and molded into a wide range of shapes without cracking, splintering, or compromising its performance. It unlocks a new dimension of design freedom while delivering the strength and sustainability today’s projects demand.

What Is Thermoforming?
Thermoforming is the process of softening a material using controlled heat, then bending or molding it into a desired shape until it cools and holds its new form. This is a method commonly used in plastics but is also applicable with ACRE which is around 50% rice hulls by volume.
ACRE responds exceptionally well to thermoforming. It softens evenly under extreme, applied heat, allowing for smooth, precise shaping without compromising strength or surface quality. The result is a material that can bend into curves, arches, and flowing profiles while maintaining the natural wood-like texture and grain that sets ACRE apart.
This process makes it possible to create curved facades, rounded soffits, seamless trim transitions, and even custom signage—all with a material that is durable, sustainable, and easy to work with on site.
Why Thermoforming Matters in Modern Design
As architectural trends move toward more fluid, organic, and expressive forms, designers are increasingly moving beyond traditional structures. Curves can soften a space, improve flow, and create focal points that elevate both visual and functional impact. However, achieving these shapes has often required compromise of not having the much loved beauty of wood.
Thermoforming bridges that gap by making curved design elements more accessible and efficient to produce. With ACRE, design professionals can now integrate these forms using a sustainable material that works with standard tools, performs in demanding environments, and maintains a refined aesthetic.
Applications for Thermoformed ACRE
The ability to shape ACRE into curves and shapes opens up new design opportunities across residential, commercial, and public spaces. Whether used for subtle architectural accents or bold design statements, thermoformed ACRE can be used in a variety of applications:
Curved Facades and Wall Cladding
Thermoformed ACRE can be used to create gently arched exterior facades or interior feature walls with seamless flow. Its ability to hold shape without visible seams or fastener stress makes it ideal for curved installations that require both aesthetic impact and long-term durability.
Wrapped Columns and Structural Covers
Instead of relying on segmented or paneled solutions, ACRE can be thermoformed to wrap around posts and columns in a continuous curve. This creates a clean, modern finish with fewer joints and faster installation.
Rounded Soffits and Overhangs
Curved soffits and canopy details are becoming more common in both modern and transitional designs. ACRE’s flexibility under heat makes it a practical solution for achieving these shapes while resisting moisture and environmental wear.
Custom Signage and Decorative Features
Fabricators can thermoform ACRE into custom branding elements, curved signage, or sculptural pieces for both indoor and outdoor environments. The material holds detail well and provides a refined surface that can be finished to suit any design aesthetic.

Conclusion
As the boundaries of architecture and design continue to stretch, materials must keep pace with both creative ambition and practical performance. Thermoformed ACRE offers a compelling solution—bringing together the design flexibility of curved forms, the authentic look of wood, and the resilience of a sustainable, high-performance material.
From exterior facades and wrapped columns to interior accents and custom features, ACRE empowers designers and builders to explore forms that were once difficult or cost-prohibitive to achieve. It is not only reshaping what is possible in modern design, but doing so with sustainability, durability, and ease of use at its core.
