When you choose an aluminum sliding window supplier, the warranty is one of the clearest signals of how much the manufacturer trusts its own build quality. ALPES backs its system sliding windows with a manufacturer’s warranty that covers defects in materials and workmanship. Rather than a single blanket promise, the coverage is structured by component: the aluminum profile and frame receive the longest protection, hardware and moving parts are covered for a defined period, and glass together with perimeter seals are covered for a shorter term. The exact duration depends on the product line and your project specification — for example, the TS130 side-press sliding window and the other system series each ship with their own documented terms. Your ALPES sales representative will confirm the precise coverage period and conditions for the model you order.
ALPES sliding windows are built from 6060-T66 grade aluminum with wall thicknesses from 1.8 mm to 2.5 mm, meeting or exceeding current national standards. The warranty on the profile covers manufacturing defects such as warping, cracking, or finish failure that appear under normal use. Because the frames are engineered for long service life, this is the component owners can rely on for the longest period.
The TS130 side-press sliding window uses German ROTO side-pressure hardware, 200 kg load-bearing pulleys, and an eight-point locking system. Rollers, handles, locks, and the side-pressure mechanism are covered against defects for a defined term. These are the parts that move every day, so ALPES pairs the warranty with durable, branded hardware rather than generic components.
Sealed insulated glass units are covered against defects such as seal failure leading to internal fogging or condensation between panes. Accidental glass breakage from impact is not a manufacturing defect and is outside the standard coverage, which is consistent across the industry.
The multi-chamber PA66GF25 thermal break and the four-sided continuous sealing strips protect against wind, rain, and noise. Factory sealing defects are covered; normal ageing of rubber gaskets from years of exposure is expected wear and is treated separately from a structural defect.
A warranty is only as good as the product behind it. ALPES operates a 100,000 m² manufacturing base across two production centers in Foshan and Zhaoqing, Guangdong, and builds to international building-code standards. Premium German hardware partners — ROTO, Winkhaus, CMECH, and Wehag — are specified across the range, and thermal performance reaches K-values as low as 1.3 on the AW90 passive series. For a sliding window replacement in a villa, apartment, or commercial project, that engineering discipline is what makes a multi-year warranty meaningful rather than decorative.
Like every manufacturer’s warranty, the ALPES coverage has clear exclusions. Knowing them up front prevents disputes later:
A few simple habits protect both your windows and your coverage:
If you suspect a defect, contact ALPES as soon as you notice it. Provide your order number, a clear description of the issue, and photographs of the affected window. ALPES will arrange an assessment and, where the fault falls within the warranty, repair or ｒｅｐｌａｃｅ the defective component. For a horizontal sliding window or any other system product, working with the original sales representative keeps the process straightforward because the specification and batch records are already on file.
