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.
