More than 15 million low-income households are now eligible for weatherization. With previous limits on average investment per home, not all cost-effective measures have been made - even in those homes previously weatherized. As a result of the Recovery Act, WAP funding has significantly increased to $5 billion over three years. The average investment allowance per household has doubled to $6500. Now, more complete weatherization methods can be implemented, particularly those that include today's advanced energy efficient technologies such as super-insulating windows.
While windows have generally not played a major role in WAP, windows are the single largest source of energy loss in homes. Up to 50% of heating & cooling costs are lost through typical single and dual pane windows, yielding poor energy-saving performance and low (or no) cost-effectiveness. As a result, combined with associated high labor costs (e.g. installation), audit tools have previously not accounted for windows.
The increase of per-household investment allowance, newly revised audit tools (eg. NEAT), and the advancement of energy efficient materials have made super-insulating windows available, for the first time, as a cost-effective energy efficient & energy saving solution available for weatherization programs today.

SeriousWindows WAP Series are super-insulating vinyl replacement windows designed specifically for low-income housing homes and projects administered by Weatherization Assistance Program (WAP) and States. Offering super-insulating full frame R-value of up to R-4.8, the WAP Series can reduce heating and cooling costs by up to 40%. All SeriousWindows WAP Series windows exceed Energy Star 2010 revisions (R-3.3).


Serious Materials recently acquired and reopened bankrupt factories in Vandergrift, PA and Chicago, IL - an excellent example of putting skilled manufacturing workers back on the job, while improving energy security, environmental performance, and the economy.
Every $1 million invested in energy efficiency programs creates three to four building material manufacturing jobs. Each direct manufacturing job creates an additional 2.9 indirect jobs including finance, transportation, supply chains, installers, and other related businesses – a higher "multiplier effect" than in other economy sectors including services.

"Serious Materials just reopened a manufacturing plant outside of Pittsburgh. Last year, that factory was shuttered and more than one hundred jobs were lost. The town was devastated. Today, that factory is whirling back to life, and Serious Materials is rehiring the folks who lost their jobs. And those workers will now have a new mission: producing some of the most energy-efficient windows in the world."
- President Obama, March 23, 2009

Serious Materials develops and manufactures sustainable green building materials that save energy, save money, improve comfort, and aggressively address climate change. Full frame R-value SeriousWindows™ and SeriousGlass™ commercial glass reduce heating and cooling energy costs by up to 50%. QuietRock® soundproof drywall and QuietGlass® reduce material use, enhance livability, and support dense urban construction. EcoRock™, the only true green alternative to gypsum drywall and five times more environmentally friendly, uses 80% less energy in its core production and has the potential to save billions of pounds of CO2 annually. SeriousWindows, SeriousGlass, and super-insulating ThermaRock™ drywall support energy efficiency funding programs as outlined under The American Recovery & Reinvestment Act (ARRA) including Weatherization (WAP), Green Federal Buildings, State Energy Program (SEP), Energy Efficiency Block Grants, Energy Tax Credit for Consumers, and Tax Deductions for Commercial Buildings. The company was commended by both President Obama and Vice President Biden for its advanced energy-saving materials and the work it is doing to create American green manufacturing jobs.
We work closely with local community action agencies, States, the DOE, and others to ensure the full and proper consideration of super-insulating windows. We assist with analysis and support to craft the most cost-effective WAP implementation measures. Serious Materials works with installers to deliver high-volume, logistically efficient installations and can facilitate training and recruitment.

"The single greatest immediate impact on the environment that we can have as a nation is weatherization. That's the immediate biggest bang for the buck. It has the advantage of creating jobs right here in America. This, in a nutshell, is what the Recovery Act is about. And this is the story of Serious Materials. This is the story of how a new economy predicated on innovation and efficiency is not only helping us today, but also inspiring a better tomorrow."
-Vice President Joe Biden at Serious Materials Chicago window factory, April 27, 2009
The American Recovery & Reinvestment Act (ARRA) can transform your region’s buildings and infrastructure and create green jobs while slowing climate change.
To understand this serious opportunity, read our special ARRA section and discover what’s been passed and what funds are available.

The measure of thermal insulation (e.g. of a window or wall). The higher the number, the better the insulation. Unlike typical windows, Serious-Windows technology delivers “full-frame R-value”. R-value is maintained even at the window frames, not just the center of glass (COG), to provide airtight window insulation.
“Enhancing windows efficiency is a major step forward. Windows in the U.S. are costing consumers $35 billion per year in energy. The next generation of windows could reduce this by more than half.”
