Tersicore – Designer indoor AC cover
incl. VAT
Tersicore: the indoor AC cover that brings the wall unit into the interior design
Tersicore is a designer cover for wall-mounted indoor split air conditioners, created for interiors where technical equipment should blend more naturally with the architecture and furnishings. Rather than acting as a simple panel in front of the air conditioner, Tersicore forms a decorative structure around the indoor unit and gives it a more deliberate visual presence.
It is suitable for living rooms, bedrooms, offices, hotels, retail spaces and other carefully designed interiors.
Two overlapping elements create the Tersicore identity
Tersicore is defined by the combination of two overlapping design elements. The upper section is straighter, squared and more architectural, while the lower section introduces a softer rounded line. The contrast between these two forms is the feature that gives Tersicore its distinctive character.
This means Tersicore is not simply a curved air-conditioner cover. It is a two-volume composition designed to reinterpret the indoor unit and make it work more naturally with walls, furniture and the overall interior scheme.
Metal, ACP aluminium composite panels and an internal mesh
The construction combines a metal frame with ACP aluminium composite panels. An internal mesh completes the structure and helps maintain open areas required for air exchange and airflow.
Tersicore is not intended to create a sealed enclosure. When choosing and installing the cover, the air intake, outlet, maintenance access and clearances specified by the air-conditioner manufacturer must remain unobstructed.

Why use an indoor air-conditioner cover?
A wall-mounted split unit is essential for comfort but can remain one of the most visible technical objects in a room. An indoor AC cover helps reduce that visual impact and gives designers and homeowners another way to integrate climate equipment into the room. Tersicore was created specifically to connect air-conditioning technology with a more considered interior aesthetic.
