Stevens Memorial Library located in North Andover, Massachusetts, upgraded its restroom walls with durable, design-forward surfaces using Altro Whiterock wall designs and our new half-lapping service for a virtually seamless finish.

Issue

The library wanted to renovate its restrooms with a solution that could withstand frequent daily use while also creating a more modern, aesthetically appealing space.

Approach

Altro Whiterock wall designs were selected to deliver both durability and visual appeal. Our new half-lapping service was incorporated to minimize visible seams and create a cleaner, more refined appearance.

Solution

By utilizing our half-lapping service, the wall panels achieved a virtually seamless finish that enhanced the overall design while maintaining the long-term performance needed for a high-traffic environment.

Product information

Altro Whiterock wall designs is designed to perform in high-traffic commercial environments, including wet areas, offering the perfect balance of practicality and beauty.

Half-lapping is a precision routing method that helps panels fit together more seamlessly, while also making life easier for installers.

Testimonials

“From an install perspective, half-lapping makes a noticeable difference in how clean the finished walls look. It helps keep the visual flow consistent, especially in spaces with patterns or design detail, where joints would otherwise be more noticeable.”

“Half-lapping helped streamline the installation process by reducing the amount of joint work needed in the field. With less finishing at the seams, the install stayed more efficient and required fewer on-site adjustments, which helped keep the schedule on track.”

“I would recommend half-lapping. Beyond the appearance, half-lapping contributes to a more durable and hygienic finished surface. The tighter joints help support a more watertight installation and make the walls easier to maintain long term.”

 

“Half-lapping fits well into the way we already install wall systems. It doesn’t change the core process, it just integrates into it, which makes it easy to adapt on different projects without disrupting established workflows.”
