Product parameters

High quality, high strength, low thermal conductivity insulation materials compound with wall thickness 0.1mm precision stainless steel profile, REMARKABLE? warm edge spacer’s thermal conductivity is only approx. 2% comparing with the traditional aluminium spacer. It decreases Uw 0.1-0.2w/m2k using REMARKABLE? warm edge system,which can significantly improve energy-saving insulation effect for the windows, doors and curtain wall system.

Material Thermal conductivity
High performance insulation material 0.17
Stainless steel 17
Glass 1
Aluminium 160


Product pass the -40°—80°alternated heat test according to automotive level PV1200 ;

Pass the test of Dew point, Performance to resistance ultraviolet radiation and Water vapor permeability according to GB/T1944-2012; The spacer passes the Environmental certification of ROHS2011/65EU.

The Remarkable warm edge spacer’s stainless steel surface improves the supporting strength of the spacer. And it can bond well to a variety of sealing materials, ensure the tightness of insulating glass.

Also, because the Remarkable spacer linear expansion coefficient is very close to the glass, which avoid the failure caused by adhesive surface expansion difference shear, to more efficient assure the sealing life time of the insulating glass.


The bending performance is similar like the bendable spacer, the manufacture can bend the spacer on the existing automatic stainless steel spacer bending machine, There is no need to add additional cost. Any shape can be processed according to customer demand, convenient desiccant filling and no leakage. The product is well adapted to modern automated insulating glass production.

High Price Ratio

The product has the excellence stability, excellent energy saving performance, and can minimize condensation on the glass and windows, reduce mildew possibility; Reducing the glass thermal stress, prevent the glass breakage; Create a comfortable indoor environment for users, meet the needs of high-end users of high quality insulating glass doors and windows, it’s the first choice of the passive house and energy saving doors ,windows and curtain wall. The product has the wider butyl coating surface than the normal aluminium spacer, assure the better gas retention rate of the insulating glass with gas filling, it’s the ideal choice for energy-saving insulating glass used for curtain wall.
