Formwork material that realizes large spaces with high-strength waffle slabs. Specially shaped polystyrene foam exhibits excellent sound insulation and thermal insulation performance.
The "Waffle Wide Slab Method" uses insulation material made of expanded polystyrene foam (EPS) with dimensions of 910mm in width, 1,820mm in length, and 50mm in thickness to form a waffle-shaped slab. This product, which suppresses floor deflection by allowing concrete to enter in a grid pattern during construction, enables the creation of large spaces up to 10m x 10m without load-bearing walls. It also possesses sound insulation performance that meets the weight floor impact sound level LH-50, and its performance has been confirmed to reach the highest grade "5" of the Japanese housing performance display standards. Additionally, the back of the panel is equipped with steel bars that can be fastened with screws at 303mm intervals, eliminating the need for substructure installation and allowing for direct attachment of interior materials.

basic information
【Features】 ● Choose from two types of panels according to scale: Wide waffle panel (protrusion 760×760mm) and cross-line panel (86.5×86.5mm) are available. ● Achieve large spaces with high-strength slabs: High-strength waffle slabs can be created without much effort, eliminating the need for load-bearing walls and beams, allowing for approximately 100m² of large spaces. This enables spacious use of interiors and flexible future renovations. ● Excellent sound insulation and thermal insulation performance: Clears weight floor impact sound LH-50, maintaining high thermal insulation performance with a thermal conductivity of 0.031W/(m·k) over the long term. ● Reduces construction work and shortens construction period: Reduces the installation work for interior materials, and can be laid without partition boards, eliminating the need for installation and dismantling work. Electrical indoor wiring can be done without embedded piping in the structure. 【Message and Precautions】 - The insulation material is susceptible to organic solvents (excluding alcohol) and petroleum products, and has properties that cause deformation at temperatures above 80 degrees, so care must be taken regarding the method and location of installation. - Although flame retardant treatment has been applied, it can catch fire if there is a source of ignition. During construction, measures should be taken to prevent fire, such as protecting areas affected by sparks during rebar welding with protective sheets. ● For more details, please contact us or download the catalog.

Company information
Born in Hokkaido, we operate a franchise business that supplies "Hero Mansion" and "Star House" through a network of approximately 60 affiliated companies, centered around our unique AE2 construction method that pursues cost efficiency and high performance. The use of formwork-compatible insulation materials reduces construction costs while also lowering energy costs, achieving the most important performance required in modern buildings. Additionally, our efforts to reduce on-site construction costs led to the birth of the "Factory-produced Unit-type Housing U&U" product after the earthquake, which has received positive feedback as a housing option that can be constructed in a short period even amid a shortage of local craftsmen. For the past three years, we have also been engaged in the sale of solar power generation systems that contribute to CO2 reduction, expanding our achievements in the construction of power generation facilities for rental housing and ground-mounted installations nationwide.
