1951 abandoned house is transformed into an energy-efficient home.

Arizona

Using strategies including the R-Tech Wall System, the home was able to achieve a high Gold rating certified under the Phoenix Green Construction Code.

Before

Before Retrofit

This Arizona residential retrofit became the first project to be certified under the Phoenix Green Construction Code, receiving a Gold rating from the program. The deep retrofit project aimed to conserve water and energy, on an existing 1,000 square-foot, abandoned house originally built in 1951, and transformed it into a cutting-edge, energy-efficient home with 1,970 square feet, four bedrooms, and two bathrooms. Using strategies including Insulfoam’s R-Tech in the wall assembly the home was able to achieve a high Gold rating. The R-Tech insulation panels are large and can be assembled in the wall system continuously to reduce the amount of gaps in insulation for cold air to escape, or warm air to come in. Reducing gaps and increasing insulation was key to this home being able to reach its energy goals.

THE PROBLEM

During Construction

During Retrofit

The project started with a 1951 home that was stripped and abandoned for over 5 years when it was acquired. The project team’s goals were to turn this 50’s style home into a sustainable residence of strategies on a budget of $95 per square foot, all while in the Arizona heat. The project team took the 1,000 square foot ranch style home and completely renovated the existing living space top to bottom, while adding another 900 square feet of living space. Insulfoam R-Tech was chosen to reach its goals of large reductions in energy use and reduce landfill waste during the construction process.

The R-Tech insulation panels are large and can be assembled in the wall system continuously to reach the following goals:  air infiltration and moisture penetration are eliminated, thermal bridging and thermal shock is greatly reduced, surface cracking is minimized, and the EPS material does not sustain mold and mildew growth. These benefits lead to lowered operating costs to improved occupant comfort. 

THE SOLUTION: R-Tech Wall System

R-Tech has no thermal drift.  Designers are well served knowing the R-Tech thermal properties will remain stable over its entire service life.

R-Tech has no thermal drift. Designers are well served knowing the R-Tech thermal properties will remain stable over its entire service life.

Environmentally Friendly: R-Tech contains no dyes, may contain recycled material and the foam core is 100% recyclable.

User Friendly: R-Tech can be ordered with the InsulSnap feature which scores the product longitudinally at any pre-ordered interval (commonly 16” or 24” o.c.). The InsulSnap feature minimizes labor by enabling the installer to cleanly break the product at the desired width while also minimizing product breakage and waste.

Insect and Mold Resistant: R-Tech is manufactured with an inert additive that deters termites and carpenter ants. R-Tech does not sustain mold and mildew growth.

Water Resistance: R-Tech facers provide a surface that is virtually impervious to moisture.

Jobsite Durability: With a polymeric facer on either side of the R-Tech, it is an extremely flexible and durable insulation.

Stable R-Value: R-Tech has no thermal drift. Designers are well served knowing the R-Tech thermal properties will remain stable over its entire service life. R-Tech is eligible for an Insulfoam 20-Year Thermal Performance Warranty – a warranty that’s not prorated or limited to a percentage of the published R-Value.

Cost Effective: R-Tech is typically less expensive than other comparable insulation products.

Proven Performance: The same fundamental chemistry has been in use since the mid-1950’s, so the actual performance of the product is well known. 

Insulfoam EPS:
From foundation to roof and everything in between

High Performance.  Lower Cost.  Most R-Value Per Dollar.  Many architects and contractors are familiar with EPS insulation as a cost-effective option for roof applications; however, EPS’ benefits expand a wide range making it easier than ever for designers to create an energy efficient building project.  InsulFoam EPS rigid foam insulation has been used for decades by smart industry professionals looking to achieve high thermal properties for a cost-effective price.  In fact, EPS offers more cost savings and higher R-Values than any other rigid insulation.  The benefit of lightweight EPS goes far beyond price, since it also helps contractors significantly decrease material and labor expenses.  View all EPS project profiles:  Roofing, Below Grade, Walls, Geofoam, Premier SIPs.
