Ergovent Frameless Insertable Line Grille, 1050 mm, with 90 mm connection diameter - modular - 2 slots

Ergovent plasterable frameless linear grille 1050 mm with 90 mm connection diameter - modular - 2 slots

The Ergovent plasterable frameless linear grille of 1050 mm is a linear ventilation grille specially designed for installation in plasterboard ceilings and walls. The Lineo Pro Puzzle creates minimalist, subtle slots in the surface, making it nearly invisible and seamlessly integrated into the interior design. The grille is designed for flexible plastic duct systems with a connection diameter of 75 or 90 mm. The base plate with two slots is made of PVC and the plenum is made of EPP.

Installation of the ventilation grille

The Lineo Pro Puzzle is mounted on plasterboard profiles and can be connected to form longer, continuous ventilation slots. The puzzle system effortlessly clicks the segments together, ensuring a neat, invisible joint. For proper adhesion, it is important to first clean the surface and any joints from dust. To prevent cracking in the finish, it is recommended to apply a thin layer of glass fibre mesh over the visible surface of the grille. After this, a primer can be applied to the areas that will be plastered. Following the surface treatment, the grille is fixed in place and the duct system connected; the entire assembly is then finished and painted in the same colour as the ceiling for a clean, seamless appearance. The Lineo Pro Puzzle has a fixed length of 1050 mm and can be extended by connecting multiple Lineo Pro Puzzle grilles, connectors, or corner pieces. Duct connections or covers are mounted at a 45-degree angle on the rear side.
