Building services can more easily align with prestige interior design fashions with a new option in ventilation.

Reflecting trending designs in commercial buildings, Gilberts has refined its linear bar grille border options to enable plasterwork to run right up to the vents cut out in the facade. Thus, the design aesthetic is maintained without a visible chamfer or flanged edge. Further, it simplifies the installation process and finish for contractors.

The new plaster border option features an elongated external flange, which is screw-fixed into place, and then simply plaster-skimmed over.

“Many of our linear grilles are used in high-end office and leisure developments, where the quality of finish is paramount. Our whole ethos is to give specifiers and contractors the ability to achieve the design brief as efficiently and cost-effectively as possible,” explains Gilberts’ sales director Ian Rogers. “Devising a plaster-in option is a little thing that makes a big difference to the overall aesthetic.”

Gilberts’ aluminium linear bar grilles have been designed to meet exacting performance criteria. They deliver smooth, accurate air distribution, via a discreet control vane in each bar grille that directs the airflow as required in either direction horizontally or vertically.

Blade angles can be set at 00, 150 or 400 depending on airflow pattern required. A free ventilation area up to 77% can be achieved depending on the grille configuration: Gilberts can CFD computer model ventilation volume and throw, air change, and noise reduction, if required.

A choice of slot numbers and widths in each unit enable precise tailoring to each project’s specific requirements.

Units can be supplied in widths varying from 50-600mm and lengths up to 2.4m; the grilles are designed to enable seamless connection to achieve longer runs without impact on aesthetics.
