Fixed windows achieve U-0.09 (R-11) and operable windows reach U-0.12 (R-8.3), optimizing energy efficiency in multifamily, office, and institutional settings. Quad-pane options achieve center-of-glass U-0.066 (R-15).
Multi-chambered, fiberglass-reinforced uPVC frames reduce thermal bridging, maintaining strength in high-traffic commercial environments without steel reinforcement.
Directionally tuned ThinGlass options in triple- and quad-pane configurations deliver advanced thermal control for energy-intensive commercial spaces.
Proprietary gas retention system ensures reliable thermal performance across varying elevations, ideal for high-rise projects.
Low air infiltration rates (as low as 0.01 CFM per square foot) enhance indoor comfort, meeting stringent commercial building standards.
Fusion-welded corners and robust glass systems guard against air and water infiltration in demanding commercial environments.
High-performance glass options include triple and quad-pane glazing, offering sound reduction up to 45 dB.
2" sash pockets provide additional sound insulation, reducing noise in busy commercial zones.
Proprietary lead-free, AAMA “PB-free” certified frames align with commercial sustainability and safety standards.
99%+ UV blockage safeguards interiors from fading in office, retail, and educational facilities.
As a global leader in ultra energy efficient window, door and glass solutions, all Alpen Tyrol Series windows and doors are carefully designed to meet the energy efficiency needs of our changing world.

INSTALLATION GUIDELINES:
The Residential Tyrol Series offers a full lifetime warranty for as long as you own and reside in your home.
Visit Warranty PageAlpen was the first North American window manufacturer to achieve dual certification from both PHIUS and PHI. We specialize in high-performance building products, with a focus on energy-efficient windows and doors. Our Passive House-certified products help architects, general contractors, and developers meet or exceed modern energy codes and build climate-responsive buildings.
Yes, uPVC windows and doors are highly energy efficient. They are designed with excellent thermal insulation properties that minimize heat transfer, helping to maintain consistent indoor temperatures and reduce heating and cooling costs. Additionally, uPVC frames are durable and require low maintenance, while their tight seals prevent air leaks, further enhancing their energy efficiency.
uPVC windows typically last between 20 to 30 years, depending on factors such as the conditions of installation, amount of use, climate exposure, and how well they are maintained. The durability of uPVC, along with its resistance to rot, rust, and corrosion, contributes to its long lifespan, making it a reliable choice. The Tyrol Series includes a full lifetime warranty while you own and reside in your home.
The best energy-efficient windows use advanced frame materials with high thermal resistance. Then they incorporate multi-pane insulated glass units with gas fills between the panes. Finally, precise construction prevents air leakage.
uPVC doors and windows often cost more than traditional alternatives like vinyl frames because of the higher quality of materials and components. The manufacturing process for uPVC, which includes special additives and stabilizers to improve performance and longevity, can also add to the cost compared to vinyl. However, their ability to reduce energy bills with better insulation, coupled with minimal upkeep over the years, often makes uPVC a cost-effective choice in the long term.
