Crossflow are market leaders in the design, supply and installation of ventilation louvres in the Irish construction industry. We manufacture a wide range of ventilation louvres that provide a combination of effective weatherability and airflow that is unsurpassed in the industry.

Our Louvres are the most aerodynamically efficient louvres available on the present market that provide maximum coefficient free area. The construction of the louvre comes in five uniquely designed components, blade, mullions, clipping system, casements and fixing brackets. Once installed, the louvres are virtually maintenance free, eliminating the need for costly maintenance contracts.

Levolux louvres are available in various sizes from 50mm, 75mm, and 100mm contour blades to 167mm screening louvre. For maximum weatherability while maintaining free airflow, we suggest the High Performance VLS50XHPO/DB louvre. This louvre allows us to achieve a nominal free area of 52%, while still maintaining a Class A rating.

Crossflow also provide an Acoustic Louvre which is manufactured to achieve noise reduction, while maintaining the requirement for natural ventilation.

All louvres are powdercoated to any RAL or BS colour and can also be anodised to BS 3987-AA25. We also provide a Decral finish effect, coated onto the aluminium producing a startlingly accurate wood or marble effect at a fraction of the real cost of these materials and still carries a 25 year guarantee.
