Interior Finishes
Coordinate material, finish, color, texture, and furniture selections to complement the
overall building design and image. Select surface materials and furnishings to express
a warm, intimate, and relaxed atmosphere. Use local materials to the greatest extent
practicable to reinforce the user's sense of place or region. Use colors and finishes of
surface materials to highlight and differentiate spaces designed to accommodate
different types and levels of activity. Avoid glare and brightness differences, which may
be disturbing or disruptive to readers, through lighting design, color, and finish
selections. Avoid an overly cluttered appearance that may be too distracting when one
is trying to concentrate on reading and studying.
3-4.3
Flooring
The library should be carpeted throughout, except as noted for heavy traffic areas and
some individual spaces. Comply with the guidance provided in ETL 03-3, Air Force
Carpet Standard. Tile, stone, or wood may be used for high traffic areas, like foyers
and lobbies, and to reinforce desired circulation paths within the facility. Ceramic tile is
the preferred flooring material for bathrooms. Flooring choices should be durable, easy
to maintain, and easy to roll carts laden with books and other materials. Avoid using tile
or other noisy flooring selections for areas of frequent cart traffic, due to the potential
noise and transition strips required. Consider sound absorption issues when selecting
flooring materials. Ensure that carpets and other flooring materials, such as rubber,
comply with applicable Air Force and MAJCOM criteria.
3-4.4
Interior Walls
Walls may be composed of gypsum wallboard on steel studs, block walls, plaster on
block walls, or other similar systems. Some spaces, like work rooms, computer labs,
and study areas, may utilize a vinyl wall covering with a Teflon coating as a wainscot on
the lower part of the wall with chair rails for wall protection. Vinyl wall covering
wainscots may also be used for private offices, group study rooms, and conference
rooms. Gypsum walls should utilize a slight textured, egg-shell finish and be painted
with the base standard interior wall paint color. Walls in hallways should be painted the
base standard interior color without chair rail trim and vinyl wainscots. Use low sheen
paint for all painted wall surfaces and a medium sheen enamel or acrylic polyurethane
for painted metal surfaces. Trim and millwork components shall be semi-gloss enamel
or a natural stained finish. Partitions may be single layer gypsum wallboard, but should
have cavity insulation and should be completely caulked at the top and bottom of each
partition.
3-4.5
Ceilings
Acoustical ceiling tiles should be provided throughout a majority of the facility spaces,
with the exception of service areas. Consider using a tile with .85 noise reduction
coefficient (NRC) for large, open spaces and quiet rooms. Acoustical panels should
also be provided, where necessary, to meet acoustical criteria. Consider the use of
cloth banners to modulate noise, as well as add color, interest, and way-finding cues.
Gypsum ceilings may be utilized in areas, like above the circulation desk, to accentuate
interior architectural features and improve the functionality of specific areas.
