Hardie® Trim-Over™ Method recognized for efficiency and waste reduction
The Hardie® Trim-Over™ Installation Method was designed to minimize waste, reduce resource consumption, and streamline the installation process. Unlike traditional approaches where trim is installed before siding and extensive caulking is required to seal cut edges, the Hardie® Trim-Over™ Method reverses the sequence. Siding is installed first, followed by trim that beautifully covers the cut edges.
This simple yet powerful shift yields a cascade of sustainability and productivity benefits:
- Material Reduction: By installing siding before trim, you eliminate most caulking — a costly material that must be replaced over time. This reduces the volume of materials consumed per project and lowers the environmental footprint associated with manufacturing and transporting caulk.
- Waste Minimization: The method leverages a highly efficient score-and-snap technique, reducing the need for precise measurements and saw cuts. Installers can stage and install siding continuously, resulting in less offcut waste and fewer errors.
- Energy Efficiency: Faster installation means less time on-site, which translates to reduced energy consumption from tools, vehicles, and jobsite operations. Studies show a 30% average increase* in installation speed compared to traditional butt-to-trim installation.
At its core, this method is backed by the trusted protection of Hardie® fiber cement. Engineered for long-term performance, our products hold little appeal to pests, resist the effects of moisture, and are noncombustible.**

*Standard installation rate determined using a standard wall design. Actual rates vary by wall complexity and crew experience.
**Hardie® fiber cement products are noncombustible and/or have a Class A fire rating when tested in accordance with ASTM E84. Fiber cement fire resistance does not extend to applied paints or coatings, which may be damaged or char when exposed to flames. The use of noncombustible siding, combined with other fire mitigation measures, may help harden a home against external fire.
