The Advantages of Polystyrene in Architectural Moldings



EPS (expanded polystyrene) foam is a closed-cell, stiff foam used in non-weight-bearing architectural and artistic projects. EPS foam’s tight cell structure ensures little water absorption and vapor permanence. The hot wire cutting technique’s accuracy to detail the contour and base of the molding is one of the polystyrene benefits for creating fascinating architectural profiles. Because of its natural lightness and resistance to moisture, your architectural shapes will be easier to move, safer to handle, and more durable.

The advantages of using EPS foam are numerous. Styrene packaging is also catching up with the trends in technology. EPS foam is mold and moisture resistant, which means it won’t degrade like other building materials over time; it also has a consistent thermal resistance, making it an energy-efficient insulation option. EPS foam is a great building material for warmer weather settings because of its long-term heat resistance.

A two-step technique is used to make EPS foam. Raw polystyrene beads are steamed and then cured in big bags to make pre-puff polystyrene beads. After being cured, the pre-puff beads are placed in a block mold and steamed a second time to produce raw EPS foam. The newly produced EPS foam blocks are then taken to a storage area where they can age for the required amount of time once the molding process is completed.


Moldings for Home

Exterior moldings may completely change the look of a home—a simple construction into something magnificent. The first to do so were the ancient Greeks. Exemplify this with intricately sculpted. Today, there are no moldings on temples. Need to carve for long periods created synthetic replicas of moldings are now accessible to provide a framework curb appeal instantly. The use of architectural foam moldings deceives the eye. They appear to be made of stone or wood to the naked eye. To put it another way, it’s all a perfectly created illusion. Impress your neighbors or bystanders. Parapet molds, architrave moldings, pyramid tops, arches, and window banding, to name a few, can all be made out of EPS.

The following are some examples:

  • Feature columns
  • Decorative Fence Capping
  • Front Portico features
  • Molding restoration and repair

Cutting an EPS foam Block for architectural molding

They begin with a large block of foam. Activate a foam cutter with a hot wire. It melts under the supervision of computer software. It made its way through the dense foam block to produce complicated and accurate cuts. This automatic hot wire is in the process of cutting. Architectural molding is a type of trim that is used to decorate the outside of a building. It carves an opening in the form of windows or doors—a cost-effective strategy to reduce waste. The heated wire has completed its task. Rises to leave a trail of smoke. During the burning operation, a worker pulls out each architectural piece’s moldings. The block has a length of two and a half meters. The hot wire is now carving an intricate design. This is done half at a time—a Roman-style column carved in the past, currently being reproduced in foam instead of stone. Thus the aesthetic of the old world can now be replicated completed with the least amount of physical effort. They employ a heated wire form to make an arch. Instead of a straight computerized wire, they put it in front of a curving wall. Pushing a piece of foam rubber driving wheels These are the foam through the hot wire. The wheels have been calibrated to be as accurate as possible. Control the slash. As a result, an arch has been created. It will be a perfect match to the linear Trimmings made beforehand to ensure that they will fit. They use carved together seamlessly. A foam wedge to imitate the Keystone lock pieces in stone arches is utilized and united.

Arch with architectural molding

Currently, a worker is wrapping the cut foam. Pre-infused fiberglass mesh moldings adhere to the surface rapidly when using glue. This mesh gives strength to the foam. It also causes it to break as a result of the mold. Next, resistant cement flows underneath the hopper and onto the molding. Moldings are inserted into a template. They use the same contours as before to apply a uniform layer of cement on the surface and sides. This isn’t just any cement; it’s a special one. The combination has been pre-engineered and strengthened with a unique resin to make a long-lasting finish for mesh-covered moldings. The moldings are then transferred to another worker. This must cure for at least 24 hours before applying a second coat of cement. It’s this one, which has a considerably more delicate texture. Using cement to an arch is substantially more difficult. Thus they take a shaped piece of molding staff with a more hands-on attitude squirts cement onto the woven foam. They then slide the custom-made semicircle instead of using a template over the molding. It’s a challenge to force the molding through it. This arch is now complete. They use the same method for smaller orders as well. There is no need for a machine to cement manually. When there are only one or two machines, the worker progressively lowers the template with the use of a track on the table’s side, affix cement to the foam, and make it appear as though the second layer of stone is given a boost with the use of a Roman-style column. The worker applies the cement to the surface with great care. Grooves ensure total coverage and finally push the template across the screen, brushing the surface lightly to get a finer texture. These are now Moldings are ready to be used to provide interest and detail a structure’s definition.

Architectural foam is lightweight, moisture-resistant, and appropriate for interior and exterior use, making it a cost-effective alternative to wood, plastic, and concrete. Foam Design Center products can meet or surpass your expectations, from architectural foam moldings to a decorative faux beam to an ornamental foam column.
