Residential Spray Foam Princeton, NJ

Spray Foam Insulators recently completed a residential spray foam insulation project in Princeton, NJ, for a luxury custom home built with a strong focus on energy efficiency, comfort, and long-term performance.

This project is located at 6 Evelyn Pl, Princeton, NJ 08540, and is being built by Angelone Homes, a well-known design-build firm recognized locally for high-end materials, detailed craftsmanship, and strict quality control throughout the construction process.

Project Overview

• Location: Princeton, NJ
• Builder: Angelone Homes
• Building Type: Luxury custom residence
• Scope of Work: Whole-home insulation with special focus on cantilevered areas
• Foam Type Used: Closed-cell spray foam

The Challenge

New Jersey’s current residential energy standards are based on the 2021 IECC with state amendments, which significantly increased insulation requirements compared to prior building codes. These standards require higher performance levels, including R-60 for roof assemblies and R-30 for wall assemblies.

In addition to meeting code requirements, this home features cantilevered sections, which are notoriously difficult areas to insulate properly. Cantilevers are often cold due to poor insulation continuity and air leakage if not detailed correctly. The builder wanted a solution that would address both thermal performance and air sealing in these high-risk areas.

Our Spray Foam Solution

To meet the project’s performance goals, our team installed closed-cell spray foam insulation. Closed-cell foam was selected for its high R-value per inch, superior air-sealing capability, and ability to add rigidity to framing assemblies.

Special attention was given to the cantilevered areas, where closed-cell spray foam creates a continuous thermal and air barrier when properly detailed. This approach eliminates the drafts and cold floors commonly associated with cantilevers while ensuring the home meets and exceeds current energy code requirements.

Results

With closed-cell spray foam installed, the home now benefits from:

• Excellent air sealing
• High insulation values in walls and roof assemblies
• Improved comfort in traditionally cold cantilevered areas
• Long-term energy efficiency and durability
