Base profiles influence the external thermal insulation composite system (ETICS) along the entire length of the building base — both positively and negatively. Aluminum profiles, still widely used for structural stability, are highly conductive and can result in significant thermal bridging. But who wants that?
Both the Pro BSOP-HL and the Pro SOP base profiles are made of PVC and therefore inherently provide significantly lower thermal bridging than aluminum profiles. Even better, thanks to its innovative hollow-chamber geometry, the Pro BSOP-HL base profile clearly outperforms standard solid PVC base profiles.
