1.Invisible Grilles Are the Best Choice For Your Home

If you’re in the market for window grille options, you might have come across the term ‘invisible grilles’. Technically, they aren’t really invisible. But you will have to look closely to see the fine, thin wires running across.

2.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.

3. Choose whether you want them fixed in place or moveable

Fixed invisible grilles are fixed in place and cannot be moved.

Mounted onto the wall using cables, fixed invisible grilles, as their name suggests, cannot be moved after installation. They are usually used for balconies without existing window structures or in homes where additional structures cannot be installed like in certain condominiums. Do note that you will need a solid concrete wall to install fixed ones. They cannot be installed on fake walls or walls made from materials not as sturdy like wood for instance.

4 Invisible grilles are plenty hardy

Besides being made from a hardy material like stainless steel, invisible grilles with a 2-mm thickness can hold a maximum weight of about 180 kg. Bailing’s invisible grilles however, are 2.3 mm thick, which means they can hold a maximum weight of 234 kg.

Invisible grilles also cannot be cut using ordinary scissors. So for folks with young children, there is no need to worry about your tykes cutting through the grilles during an unsupervised crafting session.

The grilles can however be cut using a wire cutter, so be aware that invisible grilles shouldn’t be used for deterring whoever’s outside from coming in e.g. burglars, but rather to keep the occupants inside the home safe.
