Sheet of foamboard

Foamcore, foam board, or paper-faced foam board is a lightweight and easily cut material used for mounting of photographic prints, as backing for picture framing, for making scale models, and in painting. It consists of a board of polystyrene foam clad with an outer facing of paper on either side, typically white clay-coated paper or brown kraft paper.

History

The original white foamcore board was made in 1'8-and-3'16-inch (3.2 and 4.8 mm) thicknesses for the graphic arts industry by Monsanto Company under the trade name "Fome-Cor®" starting in .[1]

Construction, variants and composition

The surface of the regular board, like many other types of paper, is slightly acidic. However, for modern archival picture framing and art mounting purposes it can be produced in a neutral, acid-free version with a buffered surface paper, in a wide range of sizes and thicknesses.

Foam-cored materials are also now available with a cladding of solid (non-foamed) polystyrene and other rigid plastic sheeting, some with a textured finish.

Foamcore does not adhere well to some glues, such as superglue, and certain types of paint. The foam tends to melt away and dissolve.[citation needed] Some glue works well in casual settings, however, the water in the glue can warp the fibers in the outer layers. Best results are typically obtained from higher-end spray adhesives. A hot glue gun can be used as a substitute, although the high viscosity of hot glues can affect finished projects in the form of board warping, bubbles, or other unsightly blemishes.

Self-adhesive foam boards, intended for art and document mounting are also available, though these can be very tricky to use properly; this is because the glue sets very fast. It is considered cheaper to buy plain foam board and use re-positionable spray mount adhesive.

Specialty constructions have been developed for engineering uses.[2][3]

An architectural model made from foamcore on a styrofoam base

Foamcore is commonly used to produce architectural models, prototype small objects and to produce patterns for casting. Scenery for scale model displays, dioramas, and computer games are often produced by hobbyists from foamcore.

Foamcore is also often used by photographers as a reflector to bounce light, in the design industry to mount presentations of new products, and in picture framing as a backing material; the latter use includes some archival picture framing methods, which utilize the acid-free versions of the material. Another use is with aero-modellers for building radio-controlled aircraft.

Researchers at the University of Manchester created their Giant Foamboard Quadcopter (GFQ) claimed to be the largest possible Civil Aviation Authority licensed drone with an all-up weight (UWT) just below the maximum of 25 Kg (c.55 lbs).[4]

 Cold storage
The xps extruded foam board is indispensable in the construction of cold storage. It not only plays a role in heat insulation but also because of the microporous structure on the surface of the xps foam insulation board. It can slow the condensation of water vapor and reduce the formation of water droplets. 
Special conditions for cold storage xps extruded boards are relatively high, and the thickness needs to be more than 10 cm. Therefore, in the construction of cold storage, two layers of xps extruded plates are usually used. One reason is to increase the thickness, and the other is to double-layer extruded sheet with staggered stitching to increase heat insulation to prevent temperature loss.

 Road foundation
XPS extruded board can be used as foundation pavement, airport road expressway, etc. The extruded board is waterproof and moisture-proof. It cannot be degraded and impermeable for up to 50 years. These advantages effectively alleviate the ground collapse caused by road leakage.

 Decorative extruded board
Extruded polystyrene foam board can be used for home floor decoration. First of all, the XPS extruded board is softer, and there will be a certain buffer when people step on it. The closed-cell honeycomb structure of the extruded polystyrene insulation board can ensure that only a thin layer is required to achieve good thermal insulation and waterproof effect. There is a limit to the height of the interior. For home decoration, the thinner the foundation, the larger the indoor space.

In short, the xps foam insulation board is suitable for the situation where the insulation layer needs higher compression resistance. It has been widely used in wall insulation, concrete roof, steel structure roof insulation, low-temperature storage ground, parking platforms, airport runways, highways and other fields of moisture insulation. XPS insulation board is one of the best building energy-saving materials in the building materials market.
