Main Stream Home Improvement is the exclusive dealer of the Quantum2 window in the Quad Cities. According to the NFRC (National Fenestration Rating Council) the Quantum2 window with Power Q Glass is the most energy efficient window in our market and here is why….

Power Q Glass with R-10 insulating Power

  • Two panes of double strength glass for increased durability and strength.

  • Two lites of high performance PPG Solarban 60 Low E- Glass reflects summer heat away from the home and blocks 99.9% of harmful UV Rays. In winter, it reflects radiated heat back into the home reducing energy consumption.

  • Heat Mirror 88 Film reflects direct and indirect solar heat, or relative heat gain, back out and away from the room, dramatically reducing air conditioning costs. This unique film also reduces sound transmission into your home by as much as 35%.

  • Two Air spaces filled with krypton to provide superior insulation against the transfer of heat to or from the outside.

  • Twin Polymore coated steel spacers provides superior structural support while reducing condensation and thermal conductivity increasing the overall energy performance.

  • Genuine dual seal ployisobutylene (PIB) sealant system provides a second thermal break and barrier.

Foam Filled Frames and Q Foam

  • Every Quantum2 frame and sash is filled with Q-Foam, a polyurethane foam injected inside each profile to provide and R-25 rating.

49% Energy Savings Pledge

  • Every Quantum2 window is guaranteed to reduce your fuel consumption. When you replace all of your windows with Quantum2 high performance units, you'll not only improve your living comfort and your home's value, but you'll drastically slash your energy use. That's why we say Quantum2 windows are an annuity, because they will pay for themselves over time.

Glass Breakage Warranty and Lifetime Warranty.

  • Quantum2 windows are available with an optional glass breakage warranty. You'll free your mind from any future hazards with this one of a kind warranty. Should the glass on your Quantum2 break, we'll replace the parts and labor free. A warranty that guarantees your windows for life is great, but a transferable warranty is even better. In this day of mobility, you may eventually sell your home. What a better selling tool than a lifetime warranty that is transferred to the new owners. Quantum2 windows are the best in the business and it has a written warranty to back it up.
