According to recent statistics, the number of people with vision problems will surpass the 800,000 mark by the end of 2020. As such, commercial facilities must do their best to improve the accessibility of visual aids for consumers with eye problems. One way to achieve this is to use custom Braille signs inside and outside business premises. While custom Braille signs can be made from a variety of materials, most commercial facilities prefer acrylic signs. Read on to understand why acrylic is the best material for your facility's custom Braille sign.
Single Piece Means no Falling Parts
The raised dots on a metallic Braille sign are fixed to a Braille board, and this means they can be removed or fall off over time. It exposes them to faster deterioration primarily when used outdoors or on a busy hallway. Acrylic custom Braille signs do not have fixed parts since they are made from a process that uses immense pressure and heat to form a single Braille sign. Since the Braille dots are raised from the acrylic board itself, they remain intact and cannot fall or be removed. Notably, an acrylic Braille sign is excellent for commercial facilities that receive many customers with vision problems.
Low Thermal Conductivity
Braille signs are only useful if consumers with vision problems can touch them without hurting their hands. Therefore, your custom Braille signs should be poor conductors of heat, mainly if you will use them outdoors where they will be exposed to direct sunlight. Metallic custom Braille signs are the last thing you need because they are excellent heat conductors and your customer will not appreciate the burning stings they receive. Acrylic has an extremely low thermal conductivity -- 0.2 at 250C. Therefore, your customers do not have to worry about touching Braille signs, even when exposed to direct sunlight.
High Level of Hygiene
As mentioned earlier, persons with vision problems must touch Braille signs to understand the meaning. Since they are hung in public places, many people touch Braille signs, and thus, hygiene is a significant concern for most consumers. Metallic custom Braille signs must be screwed to the walls or doors to stay put. However, the joints and gaps in the screw points provide a haven for bacteria, which makes metallic Braille signs less hygienic. Acrylic, on the other hand, has excellent hygienic properties because the single-piece construction eliminates gaps and joints. Additionally, acrylic Braille signs come equipped with double-sided tapes that make installation easy and clean.
