Glass Technology

Planilux

A clear, high-quality glass designed to maximize light transmission. It provides a clean appearance and consistent clarity, making it suitable for a wide range of residential applications.

Planitherm Lux

An advanced low-emissivity glass that improves insulation by reflecting heat back inside. It helps reduce energy consumption while maintaining a comfortable indoor temperature.

Planitherm Lux II

A higher-performance glazing option designed for enhanced thermal efficiency. It offers improved insulation and solar control, making it ideal for homes exposed to varying seasonal conditions.

Performance Factors

SHGC (Solar Heat Gain Coefficient)

This measures how much solar heat enters your home through the glass. A balanced SHGC helps maintain indoor comfort by controlling heat gain during warmer months.

U-value

The U-value indicates how well a window prevents heat from escaping. Lower values mean better insulation, which is essential for improving energy efficiency in colder climates.

LSG (Light to Solar Gain Ratio)

LSG compares visible light transmission to solar heat gain. A higher ratio allows more natural light while limiting unwanted heat, improving both comfort and efficiency.

Premium Components

Interlock system

Our interlock system reinforces the structural integrity of the window, creating a tighter seal between panels. This improves resistance to air infiltration and enhances overall performance in harsh weather conditions.

SWISSPACER

SWISSPACER technology enhances thermal insulation by reducing heat transfer at the edges of the glass. It also helps prevent condensation buildup, contributing to long-term durability and improved indoor comfort.
