The cavities are commonly six or eight inches wide but can be larger or smaller as needed. Special units for corners, floors, and roof assemblies round out the product lines and improve the engineering of the system and energy efficiency of the final construction.īlock sizes are typically on the order of 16 inches high by 48 inches long. These “reversible” insulated concrete forms save time during placement and prevent improper alignment. Many manufacturers have developed units with universal interlocks that allow the insulated concrete forms to stack whether the form is flipped one way or the other. The joints between individual insulated concrete forms can feature interlocking teeth or a tongue and groove configuration molded into the forming material, or simple butt jointed seams. There are advantages to each type of material, but one current trend incorporates hinges into the ties that allow pre assembled forms to fold flat for easy, less costly shipping. The ties that interconnect the two layers of insulated forming material can be plastic, metal, or additional projections of the insulation. The salvaged material is formed into blocks with cement, making units ideal for direct application of plaster finishes. A few products are made with recycled foam or wood fiber in a nod to green building. It can be extruded polystyrene (XPS), which is stronger, but also more costly. Foam is most often expanded polystyrene (EPS). Panels or planks ship more compactly, but must be assembled into formwork on the job. Large preassembled blocks stack quickly on site. The two insulating faces are separated by some type of connector or web. Whatever their differences, all major ICF construction systems are engineer-designed, code-accepted and field-proven. “Post and beam” systems have just that – discrete horizontal and vertical columns of concrete that are completely encapsulated in foam insulation. The wall produced by “grid” systems has a waffle pattern where the concrete is thicker at some points than others. “Flat” systems yield a continuous thickness of concrete, like a conventionally poured wall. The Thermomur ® 350-series satisfies the new changes to Part L of Building regulations.Insulated concrete forms systems can vary in their design. Thermomur ® 350-series provides a two sided thermal insulated, airtight construction which offers optimum energy efficiency, excellent sound reduction and fire protection for domestic buildings, such as multi-storey houses. Thermomur ®‘s unique design allows us to meet ever demanding thermal insulation and air tightness standards with the minimum of additional components and construction processes. Buildings set up in Thermomur ® require little maintenance and are extremely durable. The blocks are stacked as bricks, reinforced then filled with concrete. Thermomur ® blocks are very light, easy to work with and the walls are built quickly and solidly on site. Thermomur ® is an ICF building system based on moulded blocks of expanded polystyrene (EPS), Jackopor ®. Bringing this innovative technology to the UK, ICF Building Solutions can utilise the years of perfecting and expertise from some of the most renowned international ICF construction specialists. The Thermomur ® range of ICF blocks have been designed with 35 years of experience and a focus on thermal efficiency, to survive the harshest of Scandinavian winters. Jackon are the leading Norwegian manufacturer of ICF building materials.
