HP+ Wall Systems

A New Way to Build 

The HP+ Wall System is designed to deliver a smart, innovative way to build affordable, high-performance homes and buildings. 

Build Stronger:  Create a stronger wall assembly and use less wood than traditional construction. 

Build Smarter:  Construct a wall assembly that incorporates continuous insulation and an air/vapor barrier system without the need for a conventional vapor or weather resistive barriers. 

Build more Sustainable:  Minimize energy loss with reduced air leakage and high R-value.

The patented HP+ Wall System combines three superior construction components: 

1. WALLTITE® 

WALLTITE is a closed-cell, spray-applied polyurethane foam that provides superior insulation, strength and energy efficiency. 

2. NEOPOR® 

Neopor is a graphite-enhanced and rigid thermal foam insulation that helps mitigate the risk of moisture inside of wall cavities. 

3. Weather Resistive Barrier 

Creates a seamless barrier of exterior protection to above grade wall substrates. 

This powerful combination delivers exceptional control of heat, air & moisture and increases structural integrity. 

Low Score, High Value 

The superior durability and performance of the HP+™ Wall System can help builders meet new and challenging code requirements and improve Home Energy Rating System (HERS) index scores.  This award-winning high-performance wall system is an excellent solution for progressive builders looking to optimize their construction designs, reduce wood and minimize thermal transfer in the building envelope. 

Building more energy efficient and durable homes with a strong resale value is just another reason clients gravitate to builders' like Tim O'Brien Homes. Homes like these can more easily comply with ENERGY STAR® v3.2 and/or DOE Efficient New Homes program requirements.  Many of the components of this high-performance system are also ENERGY STAR certified insulation materials.  Structural design values for the HP+™ Wall System are found in the Technical Evaluation Report (TER).
