Half Dome Acrylic Mirrors

Half dome mirrors at National Safety Mirror are great for blind-spot elimination and to prevent traffic accidents in your office, warehouse, or shop. Half dome mirrors provide a 180-degree view and mount at the intersection of a wall and ceiling.

The image below is a good example of how a half-dome mirror may be used in an office, warehouse, or parking garage mirror to avoid accidents. What you can see in this mirror is how office hallways intersect with each other. Someone walking up the center hallway, for example, towards the intersection, can see oncoming traffic.

You can also see how this half dome mirror is mounted flush up against the ceiling. Although dome mirrors are available with hardboard, heavy-duty plastic, and galvanized steel options, there’s really no need to have backing at all. If you really want a backing for an indoor 180-degree dome mirror, the hardboard backing is a good choice.

If this mirror is going in a parking garage where water or moisture could leak into the mirror, we recommend the HDPE (high-density polyethylene) heavy-duty plastic backing. This plastic is 1/8” thick, lightweight, and virtually indestructible.

The half dome security and safety mirrors on National Safety Mirror are available in acrylic and are primarily for indoor use with hardboard and no backing. When dome mirrors are mounted indoors, there’s really no need for backing. In situations where you need a back, the hardboard backing is the recommended choice. In most cases, a dome mirror without backing is perfectly fine. As a matter of fact, choosing a half-dome safety mirror without a backing will save you a little money.

The backing is primarily used to protect the mirror, but because the mirror is located indoors, there really isn’t a need for the backing. It is perfectly acceptable to place a piece of cardboard over the top if you want to keep debris out of the mirror, but is not mandatory.

Acrylic Half Dome Mirrors

These mirrors are constructed from Acrylic, which is the usual “go-to” for indoor safety mirrors and indoor security mirrors. Acrylic offers a bright reflection and is roughly 17 times more impact resistant than glass.

If you are looking for an outdoor equivalent for the half dome mirror to place outdoors, we recommend the new “DomeVex Security Mirror.”

Mounting a Half Dome Mirror

Half dome mirrors without a backing are mounted using the predrilled holes located on the outer flange of the mirror. For mirrors with backings, use the d-rings installed on the backing. The image below offers two examples, but for more details, please review our document on mounting dome mirrors.
