FAQ About Aluminium Sliding Window

How does the thermal break system in the CC128 work?

The CC128 features a Polyamide Thermal Break combined with an Integrated Foldable Gasket to enhance insulation and energy efficiency. The ultra-wide thermal break reduces heat transfer between the interior and exterior, while the foldable gasket ensures a superior seal, preventing drafts and minimizing energy loss.

Sliding windows are space-efficient and easy to operate. They slide open horizontally, requiring no extra clearance, making them ideal for smaller spaces. They also offer unobstructed views, plenty of natural light, and are perfect for areas like kitchens, living rooms, or patios where swing space is limited.

Casement windows seal more tightly than sliding windows, making them better for insulation, soundproofing, and air-tightness. Sliding windows are easier for wide openings, while casement windows excel in performance.

Yes, sliding windows can have small gaps or leaks due to the sliding track mechanism. These gaps can reduce the window’s airtight seal, especially over time. In contrast, casement windows close tightly against the frame, offering a better seal and enhanced insulation.
