Invisible grilles won’t rust (but only if you get the right ones)

Invisible grilles are actually made from stainless steel, encased in either plastic or rubber for extra protection. But while stainless steel is not as susceptible to rusting as other metals or alloys, it does rust, depending on what grade it is made up of. Unfortunately, not all stainless steels are made equal. Common stainless steel grades for invisible grilles include 202, 304 and 316. The first two actually do rust after being exposed to the elements for a period of time, while 316 won’t. So make sure you’re getting invisible grilles made from 316 stainless steel.

Casement or sliding invisible grilles are installed on a casement window or a sliding window (or door!), which allows you to open your windows normally without any restriction. Because they require additional structures to fix them in place during installation, they tend to make your windows appear bulkier. However, it’s a popular choice for homeowners who want or require their windows to be accessible, such as in the case of older HDB flats, where the air-conditioning compressor is located just outside the bedroom window.
