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

The 1-2-3 Power Combo

The HP+ Wall System combines three superior construction components:

WALLTITE^®

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

NEOPOR^®

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

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. The air sealing and thermal benefits of this system can also help meet the 45L Federal tax credit criteria.

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 Zero Energy Ready Homes (ZERH) 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).

Did You Know?

In regions where there are growing disaster-resilience needs, the HP+ Wall System and other applications of closed-cell spray polyurethane foam can be utilized to help mitigate these additional challenges.

Read more about how BASF spearheaded the uses and adoption of SPF materials for disaster durable construction approaches throughout the US market.

Feature Disaster Durable Solutions

Disasters happen. In fact, they are becoming more frequent, more intense and more costly. $1 billion -plus weather disasters have tripled in the US since the 1980's. They come in many shapes and sizes, creating multiple threats to the build environment in the form of hurricanes, hailstorms, flood, tornadoes, extreme cold, extreme heat, blizzards and earthquakes - as well as a myriad of manmade catastrophes.

As the world's leading chemical company, we believe chemistry is the catalyst that creates the solution to these hazards. BASF's construction chemistry has prevailed against the most severe conditions both Mother Nature and mankind have dished out, reducing the negative impact of disasters and better protecting our properties, investments and communities from this growing harsh reality.
