Extol ALU Windows in Our Offer

ALU-COLD

The ALU-COLD system is an ideal solution for interiors, business spaces, and high-traffic retail outlets. Some of the key characteristics of this system, without a thermal break, are shown in the table below:

Characteristic	Value
Uf value	1.3 W/m²K
Installation depth	75 mm
Maximum glass thickness	4–39 mm

ALU-COLD supports sash weights up to 180 kg, features 3 levels of sealing with EPDM gaskets, and provides security up to the RC3 level. Although it is not primarily intended for high thermal insulation of residential houses, the ALU-COLD window system offers outstanding functionality and durability for commercial applications.

ALU-TERMO

The ALU-TERMO system is designed for energy efficiency and is suitable for residential and public buildings, large openings, and modern facades. This system provides exceptional thermal and acoustic insulation, and some of its characteristics are shown in the table:

Characteristic	Value
Thermal break	Polyamide (24 mm & 20 mm)
Uf value	0.7 W/m²K
Construction depth	90 mm
Maximum glass thickness	20–59 mm

The Uw value with triple glazing is 2.3–2.9 W/m²K. ALU-TERMO profiles with 3 levels of sealing provide security up to the RC3 level, along with high resistance to wind and moisture.

Why Choose ALU Windows

Aluminum as a Premium Material for Windows

Aluminum stands out as a premium material in the world of joinery, offering a unique combination of architectural stability, exceptional durability, and modern design. Aluminum profiles allow for elegant and slim solutions that fit perfectly into modern architectural trends, providing a sophisticated look to your home or business space.

Stability and Long Service Life

When we talk about stability and long service life, aluminum joinery stands out as a reliable choice. Aluminum windows are designed to withstand the test of time, providing long-term security and reliability.

Minimalist Design

ALU windows fit perfectly into contemporary trends of minimalist design, offering clean lines and elegant profiles. They allow for maximum glazing and an abundance of natural light.

Suitability for Large Glass Surfaces

Aluminum windows are ideal for large glass surfaces thanks to the exceptional strength of aluminum. The profiles allow for the creation of large openings without compromising on stability and safety.

Weather Resistance

Aluminum joinery is extremely resistant to corrosion, UV radiation, and extreme temperatures, making it suitable for all climatic conditions.

Energy Efficiency and Security

The Role of Thermal Breaks

A thermal break consists of material with low thermal conductivity that breaks the contact between the outer and inner parts of the aluminum profile, thereby reducing heat transfer and improving insulation.

3 Levels of Sealing

Three levels of sealing ensure top-tier thermal and acoustic insulation, as well as protection against air, water, and noise penetration.

RC3 Protection

RC3 protection indicates a high resistance of the window to burglary. It is achieved with reinforced profiles, special locking systems, and safety glass.

Wind Stability

Aluminum windows are resistant to strong wind gusts without deformation or damage, making them suitable for windy areas and higher floors.

Long-Term Energy Savings

By reducing heat loss in winter and heat penetration in summer, ALU windows contribute to the reduction of heating and cooling costs and increase the energy efficiency of the building.

Warranty

Warranty Periods for ALU Windows

ALU windows come with clearly defined warranty periods:

5 years on aluminum profiles.

3 years on the mechanical functionality of the window.

2 years on unwanted condensation between the glass panes.

Warranty Terms

The warranty covers defects in material and workmanship during normal use. It does not cover damage resulting from improper use, installation, or maintenance.

Competitive Price List and the Best Choice for Glazing

ALU Windows as a Premium and Long-Term Investment

Custom-made ALU windows represent a long-term investment with low maintenance costs and high energy efficiency.

Choice Between TERMO and COLD Models

ALU-TERMO is suitable for external joinery of residential and public buildings, while ALU-COLD is intended for interiors and business spaces where thermal insulation is not the primary requirement.
