No-dust aluminium spacers are used when there is a 27 mm or 32 mm cavity between the panes.

Warm edge spacers are used when the cavity is 29 mm. They are made from a mix of aluminium, stainless steel and plastic, which improves the insulation value of the glazing. You can choose between grey and black.
