Glass Fiber Warm Edge Spacer Bars For Double Glazed Units Glass Panes

Glass Fiber Warm Edge Spacer Bars for double glazed units Glass Panes

Warm Edge spacer bars insulate the edges of sealed windows, keeping the glass panes apart. Typically made of aluminium, these bars are highly conductive to heat, allowing it to pass through the window.

Warm Edge spacer fiberglass composite
The use of top-grade insulation materials in Warm Edge spacer bars reduces the thermal energy consumption of traditional aluminum strips. This improves the energy-saving and environmental protection effects of building doors and windows.

The composite warm edge interval incorporates cutting-edge equipment. It combines high-end composite materials, integrating fiberglass and UPVC medical-grade materials with stainless steel 316 medical grade, using hot and cold co-extrusion technology. This creates a perfect combination of wall thicknesses at 1mm, ensuring perfect air tightness while achieving superior heat insulation. By using high-end insulation materials, it reduces heat loss from traditional aluminum, improving the energy efficiency of building windows and doors while enhancing their environmental protection effect.

Rock take the lead to adopt the US Thermtool high frequency welding technology , now we have about 25 advanced spacer production lines, more lines will be introduced in future, Rock serves a high-end Aluminum spacer for the insulating glass.

Rock now make it headquarter in Beijing. our products are very popular with worldwide market.
