ICF and ICCF forms
We are RASTRA, and we produce a high quality building system from recycled foam plastics. We pioneered the insulated concrete form (ICF) industry and invented and developed the Compound or Composite ICF (ICCF). RASTRA is the solution for this century to build environmentally conscious, energy-efficient buildings that provide a safe and healthy living environment.
Over 9 million units in service worldwide since 1972.
RASTRA panels can be stacked horizontally or vertically ' reducing the need to lift the panels. Just tilt them up, tack them with glue or clamp them for temporary support. Once you have a wall section assembled, bring it into plumb. Windows and door openings can simply be cut out. Use the panels in either direction how they will best fit the building plan. The cavities, which form the structural part once concrete has been grouted, always line up. Concrete is grouted after a complete story has been set in place.
RASTRA panels can be finished with virtually any finish material including drywall, plaster, stucco, brick or stone veneers. RASTRA works with all types of flooring systems.
RASTRA end panels are used as stay-in-place form work for insulated flat roofs or ceilings. Roof and walls are poured at the same time to form a monolithic structure.
With the two types of RASTRA panels ' the standard and the end ' any building detail can be realized.
RASTRA panels can be finished with virtually any finish material including drywall, plaster, stucco, siding, brick or stone veneers.
The insulated concrete forms are modular units that are dry-stacked (without mortar) and filled with concrete. The insulated concrete forms lock are put together somewhat like Lego® bricks and serve to create a form for the structural walls of a building. Concrete is filled into the cavity to form the structural element of the walls. Usually reinforcing steel (rebar) is added before concrete placement to give the resulting walls flexural strength, similar to bridges and high-rise buildings made of concrete.
The most insulated concrete forms (made of EPS = expanded polystyrene) are filled with concrete in 1-4 foot "lifts" to reduce the risk of blowouts like with other concrete formwork, however RASTRA invented the Composite Insulated Concrete Forms (ICCF). The ICCF''s are strong enough that walls are filled at story-height (10 to 12 feet) in one lift. After the concrete has cured, or firmed up, the insulated concrete forms are left in place permanently for the following reasons:
Building with RASTRA insulated concrete forms protects homeowners by exceeding any new energy standard.
Large wall segments up to 25ft (7m) can be pre-assembled in the factory according to customer''s plans. These panels may include window frames and some reinforcement. Custom sections can be made quickly, as RASTRA panels are taken from the store and glued to specification. No time for curing is needed.
The panels can be set in place by light duty cranes, as concrete is poured on site. Unlike prefab concrete panels, slight adjustments in size can be made on site. Damaged panels can be repaired instantly.
Straight walls without shoring and bracing in incredibly short time. The RASTRA pre-assembled wall panel makes it possible!
Interior - Drywall, plaster, stucco, tile, stone, and paneling can be applied directly to RASTRA.
Exterior - RASTRA is suitable for a wide range of exterior finishes including any type of siding, stone, brick or stucco without preparation or wire mesh.
