This OTIIMA door system is one of the most popular systems in the lineup of products. Both thermally versatile and structurally robust, it offers the flexibility for use in both warm and moderately cold climates. It allows large-glazed surfaces and offers remarkable water tightness, air permeability, wind-load resistance and thermal insulation features. Ultrathin sight lines are achieved through three distinct methods: structural glazing, reinforced components and engineered interlocking mullions. OTIIMA's framework has been purposely designed for structural integrity while maintaining a minimal visible profile.
