Product Description

DIMEX E82und is a top- performance Refractory window system which is designed as per European standard EN12608. This series is a German 7 chambers 3 seals structure with transverse chambers and stiffeners designed to prevent sinking of the inner chamber. The glass groove of E82 is equipped with o-type sealing strip to block convection and greatly improves the sealing performance of Windows. And it effectively alleviates the heat conduction, improve the sound insulation and thermal insulation effect. This series of special fire system structure, in the opening part of the fan added three "interpenetration expansion strip" slot. Each piece of glass is equipped with a "fiberglass clip" and a SS304 stainless steel fireproof strip is added in the opening part to connect with the steel reinforcement.

An innovative 3-level center seal gasket design keeps out noise, cold, damp and strong wind. The E82 features a specially designed, Uf optimized 7-chamber geometry for excellent thermal insulation. Custom-made steel reinforcements provide structural strength for large windows and combination windows, often used in high-rise buildings, but still enables a Uf of 0.9~1.1 W/m2·K including steel reinforcements. The glazing depth of 24mm adds extra insulation between glass and frames. In combination with high-performing glass this prevents water condensation on the inside of the window.
