Abstract

Nowadays, many research execute about sandwich-insulation wall for durability of wall and retaining insulation performance. But sandwich-insulation, different exterior and interior insulation, need to form-tie which supporting both side form. And because of it penetrate concrete wall, it is worried about thermal-bridge phenomenon to form-tie. So, this research classify penetration type and buried type and analysis thermal-phenomenon of each type's form-tie and insulation performance. As a result, all form-tie type little occur thermal-bridge but penetration form-tie have superior insulation performance and low U-value.
