Interior Lobby Letter Sign Designer

Product Description

This product is best suited for indoor applications like hotel lobbies and professional reception areas. Unlike an outdoor sign letter that can be hard, rounded or shiny, the texture of this dimensional letter is rich, smooth and upscale. These dimensional plastic laminated foam letters are great for lobbies, offices, medical buildings, attorneys, museums, banks, health care facilities, and retail fixtures.

These plastic laminated foam sign letters are manufactured from 13lb polystyrene foam sandwiched between two thin surfaces of acrylic veneer, then topped with a acrylic or metal laminate. The exceptionally hard smooth surfaces of the laminate provides durability and rigidity as well as moisture resistance. The letter's face is uniform and blemish free and resists dents and punctures. The high pressure laminated foam letters are available in 30 colors.

This is an interior product only as UV rays break down the polystyrene.

Letters are cut by a computer driven cutter that produces crisp edges. The sides have sharp 90 degree corners, not rounded over. The high density foam produces high quality, smooth edges, not bubbly or cellulose that looks like a sponge. The sides are available in 1/2 inch, 3/4 inch, 1 inch, 1-1/2 inch, and 2 inch thick and are a charcoal color. The thicker the letter, the more it will stand off the wall.

Letters are easily mounted in six different mounting options. If required, add additional adhesive such as silicone or double sided tape for permanent installation.

Made in America.

What type of foam is used for lobby display letters?

From in-store displays, to reception areas, to exhibits, your interior signage project will stand out with these elegant laminate display letters. The cut out letters are made with a premium grade high density foam. The foam is not a squishy sponge like material. The sides of the foam are smooth and black and we are unable to laminate the sides of the letters.

Why is a foam letter laminated?

The display wall letter is laminated because it makes the letter more beautiful and durable. These are not paper foam core letters. They are high quality lobby wall letters that come with a lifetime guarantee. The foam is available in various depths up to 2 inches and 30 high quality face colors. The premium foam laminated face is uniform, blemish free and resists dents and punctures.

How are interior foam letters installed?

Interior foam display letters are light weight so can easily be mounted with double sided very high bond tape. We recommend an additional bead of silicone adhesive in case the foam tape dries out over time. An installation pattern can be ordered along with your sign.

UPPERCASE VERSUS LOWERCASE LETTERS

typography alphabet

The font has been carefully designed to allow a viewer's eye to easily see the shape of each character. Not each character in a font is exactly the same size; otherwise your sign lettering would be difficult to read. We name the font after its uppercase letter 'A' size but most lowercase letters are shorter. Some lowercase letter shapes such as 'b d f h k l' have ascenders which can be taller than the uppercase 'A' height. Some lowercase letters such as 'g j p q y' have descenders which go below the words baseline. Uppercase letters that are rounded such as 'C G J O Q S U' are taller than an uppercase 'A' because the rounded part extends above and below the baseline. Please call us if you need to know the character's actual size and not its named size.
