★★★★★

Our energy bills dropped noticeably after installation. The house is so much quieter and we barely run the AC like we used to. Luft's team was professional from start to finish — no pressure, no upsell.

We replaced 14 windows and two sliding doors. The quality is night and day compared to what we had. The tilt-and-turn function is incredible — something we didn't know we needed until we had it.

I was skeptical at first but the showroom visit sold me immediately. Built locally, installed by their own team — not some subcontractor. Every detail was perfect. Worth every penny.

Energy Performance

Built for
Arizona's
Extreme Heat

Standard windows weren't designed for 115°F Phoenix summers. Luft Windows' GEALAN uPVC systems deliver industry-leading thermal performance — reducing solar heat gain, slashing cooling costs, and keeping your home comfortable year-round. Our European windows meet and exceed ENERGY STAR® requirements for the Southern Climate Zone — the most demanding rating category in the United States, covering Phoenix, Scottsdale, Tempe, Chandler, Gilbert, and Mesa.

U-Factor — Thermal Transmittance 0.17 Whole Window · Best Configuration
Exceptional Heat Insulation

U-Factor measures how fast heat passes through the window. Lower = better. Our top GEALAN triple-pane systems hit U-0.17 — nearly half the ENERGY STAR Southern Zone requirement of 0.30.

SHGC — Solar Heat Gain Coefficient 0.19 With Advanced Low-E Coating
Blocks 80%+ of Solar Heat

SHGC measures how much of the sun's energy enters your home as heat. In Arizona's intense desert sun, a low SHGC is critical. Our Low-E glass achieves 0.19 — blocking over 80% of solar heat vs. clear glass.

AL — Air Leakage 0.01 cfm/ft² · Multi-Point Locked
Virtually Airtight

ENERGY STAR allows up to 0.30 cfm/ft². Our triple-layer seals and multi-point locking hardware achieve as low as 0.01 — a near-airtight seal that also dramatically reduces dust infiltration during Arizona haboobs.

STC — Sound Transmission Class 42 STC Rating · Double & Triple Pane
Significantly Quieter Interiors

Standard single-pane windows rate around STC 27. Our laminated double and triple-pane systems achieve STC 42+ — a major reduction in road noise, aircraft, and neighborhood sounds for Phoenix metro homes.

01 — Frame

Multi-Chamber uPVC Profiles

GEALAN frames feature up to 6 internal air chambers that act as continuous thermal barriers. Unlike aluminum frames that conduct heat directly into your home, our uPVC profiles interrupt thermal transfer at every point — reducing heat migration through the frame itself.

02 — Glass

Low-E Double & Triple Glazing

We offer argon-filled double-pane and krypton-filled triple-pane configurations, all with advanced Low-E coatings. These microscopically thin metallic layers reflect infrared heat while maintaining high visible light transmission — bright homes without the Arizona heat penalty.

03 — Sealing

Triple-Layer Perimeter Sealing

Every Luft Windows installation includes triple-layer perimeter sealing between the frame and your home's rough opening. Combined with our multi-point locking hardware, this creates a near-airtight building envelope that stops conditioned air from escaping and outdoor heat from infiltrating.

04 — Certification

ENERGY STAR® Southern Zone

The Southern Climate Zone — covering all Phoenix metro cities including Scottsdale, Tempe, Chandler, Gilbert, and Mesa — carries the strictest ENERGY STAR window requirements in the country. Our GEALAN systems exceed all thresholds across U-Factor, SHGC, and air leakage.

05 — UV

Up to 99% UV Ray Rejection

Arizona's UV intensity fades flooring, furniture, and artwork faster than almost anywhere in the U.S. Our Low-E glass rejects up to 99% of UV rays while maintaining natural light quality — protecting your home's interior without sacrificing the brightness Arizona living is known for.

06 — Savings

Measurable Energy Bill Reduction

Arizona homeowners run air conditioning 8–10 months per year. Upgrading from older or aluminum-frame windows to high-performance European systems directly reduces HVAC load — producing meaningful monthly savings on energy bills that compound over the full lifetime of the window.

Common Questions

Questions we
get every day

Replacing windows is a big decision. Here are the questions Phoenix homeowners ask us most — answered straight, no fluff. Don't see yours? Call or text us at (480) 508-8958 and we'll give you a straight answer.

Window replacement costs vary based on window type, size, quantity, and installation complexity. European uPVC systems like our GEALAN windows are a premium product — but because we manufacture locally in Tempe and install with our own crew, we cut out the import markups and subcontractor fees that other companies pass straight to you. Contact us for a free, detailed quote — no pressure, no obligation.
Most Phoenix metro residential projects are completed in one to two days depending on the number of windows and doors. Because we manufacture locally in Tempe, our lead times are significantly shorter than companies importing from Europe — typically a few weeks from order confirmation to installation day. We'll give you a firm timeline upfront.
Yes — and arguably more so in Arizona than anywhere else in the country. Extreme heat, 299 sunny days a year, and regular dust storms put more stress on windows than nearly any other U.S. climate. European uPVC systems with multi-chamber frames and Low-E glass are engineered for high-temperature performance. Our customers consistently report lower energy bills, less dust infiltration, and a noticeably cooler home. Standard aluminum windows just aren't built for what Arizona throws at them.
A tilt and turn window has two opening modes — tilt the top inward for ventilation while keeping the window secure, or turn the full sash inward for complete opening and easy cleaning from inside. Standard double-hung windows slide up and down with a single mode. Tilt and turn windows also seal significantly better when closed — a much better option for Arizona's dusty environment.
Yes. We serve the entire Phoenix metro including Scottsdale, Tempe, Chandler, Gilbert, Mesa, and Paradise Valley. Our showroom is in Tempe at 2010 E. University Drive, Suite 25 — open by appointment. Free in-home consultations throughout the East and West Valley. Call or text (480) 508-8958 if you're not sure we cover your area.
Three things. We're the only authorized GEALAN window provider in Arizona. We manufacture locally in Tempe — faster lead times, no import markups. And we install with our own trained crew, no subcontractors. One point of accountability from your first call to the last screw on installation day. Most window companies in Arizona are resellers with outsourced labor. We're not.

Still have questions? We're happy to walk you through anything — no sales pitch, just straight answers.
