FAQ's
No. It is fitted to the inside face of external walls, so it can improve thermal performance without changing the exterior appearance.
It is often considered for solid wall homes, older buildings, or properties where external insulation is not preferred or practical.
It can reduce room dimensions slightly, so Sublime reviews layout, fixtures, and finish details before recommending a method.
Insulation changes how walls manage heat and moisture, so condition and ventilation must be considered for long-term performance.
