Thermal Barrier Surface Material High-Performance Rigid Urethane Foam (Z1 Board)

Z1 BoardZ1 Board

The Z1 Board is a newly developed heat insulation material that boasts of the industry's highest level of thermal conductivity of 0.018 W/(m·K). Like the Q1 Board, the Z1 Board offers longer-lasting heat insulation performance, with an aluminum foil surface material that provides excellent thermal shielding performance.

Thermal Barrier Surface Material High-Performance Rigid Urethane Foam (Q1 Board)

Q1 BoardQ1 Board

The Q1 Board is a high-performance rigid urethane foam with excellent heat insulation over time (thermal conductivity of 0.021 W/(m·K)). Aluminum foil that has excellent thermal shielding performance is used as the surface material.

Internal Insulation Board for Wooden Construction (Achilles JD Panel)

Achilles JD PanelAchilles JD Panel

The Achilles JD Panel is a heat-insulating composite panel optimal for insulation retrofitting of existing houses. It combines Z1 Boards, which are the pinnacle of insulation performance in the industry, with fire-resistant plasterboards.

On-Site Rigid Foaming Urethane Foam (Achilles Airlon R Series)

This heat insulation system uses a special foaming machine on-site to apply rigid urethane foam. It offers a wide array of benefits, including labor savings, reduced costs due to shorter construction times, and the creation of insulation layers with no gaps. Its excellent effects can be utilized not only in general construction but in insulation and prevention of condensation in freezers and refrigerated warehouses.
