There are many differences between hollow aluminum strip and warm edge strip, the biggest difference is that the warm edge thermal insulation and energy saving effect is better than the aluminum strip, the traditional aluminum belongs to the cold edge method, because aluminum conducts heat faster, so the energy loss is faster, narrowly speaking, we speak of the warm edge of any kind of spacer strip as long as the thermal conductivity coefficient is lower than the thermal conductivity coefficient of aluminum spacer strip, can be called warm edge, the warm edge of many kinds of rigid warm edge, flexible warm edge, rigid mainly stainless steel, fiberglass, stainless steel composite, flexible, such as super spacer strip, windows Lilai warm edge strip and so on. Rigid mainly stainless steel, fiberglass, stainless steel composite, flexible, such as super spacer, windows Lilai warm edge strip and so on.
