E65 Series Refractory Window Systems

German quality Refractory Windows with fire integrity for 60 minutes - DIMEX.

DIMEX Casement series 65mm,72mm,82mm, 90mm can be processed into refractory window systems as per your requirements. We add and build a lot of fireproof materials on the basis of ordinary Windows, so that the fire integrity of the whole window can reach 1 hour (no smoke, no fire, no air leakage).

Main Features of E65 Series Refractory Windows

1. Excellent air tightness and thermal insulation performance;

Uf 1.40 W/㎡·K (including steel reinforcements).

No fire or smoke through the closed window for an hour.

Air tightness Grade 8 [ q1 ≤0.5m3/(m·h); q2 ≤1.5m3/(㎡·h) ].

Water tightness Grade 6 (∆P ≥ 700).

Wind pressure resistance above Grade 8 (P3 ≥ 4.5 KPa).

Sound insulation Grade 5 (Rw + Ctr ≥ 400dB; Rw + C ≥ 400dB).

Heat preservation Grade10 (K< 1.1 W/㎡·K).

2. Advanced "hidden hinge" can be assembled;

3. Fire and flame retardant function;

4. Screw socket transom(mullion).

5. Available for 34 ~51mm glass configuration.

Three breakthroughs in fire resistance

1. SS304 stainless steel fireproof strips have been added to the opening part;

2. Three "interpenetration fireproof expansion strips" card slots been added to the opening part;

3. Abandoned the traditional "fire grouting" process. The "nano fireproof sticks" are used for filling. Enhanced thermal insulation and reduced sash deadweight.

The application of these three technologies, together with corresponding fireproof materials and measures, which effectively guarantees the national standard of Fireproof > 1 hour for "E65 refractory window".
