Aluminium Louvers with effective weather protection and moderate pressure drop are available in a range of blade widths and configurations. Horizontal and vertical blade orientations and a unique drainable louver make up the range. Louvers can also be supplied as louver doors or penthouse systems.

The OHL-102 and OHL-124 have blade pitches at 102mm and 76mm consecutively. They can be supplied with a flanged or channel frame. In addition they can be supplied as a motor driven closable louver.

The OHL34 (blade pitch 38mm) and OHL45 (blade pitch 50mm) are ideal for small louver jobs. They are available with either flanged or channel surround.

Holyoake Industries Model OHL-F-D offers an alternative concept in horizontal outside louvers. The drainable blade louver delivers the best water penetration performance available in a horizontal outside louver.

The OHL-F-D louver achieves this by draining the water from each blade and discharging it at the bottom of the louver through vertical down pipes found at either side of the louver.

The Holyoake OHL-KD (Knock Down) is an attractive high performance louver featuring on site assembly at the point of installation. The system is ideally suited for larger louvers and difficult on site installation. The on site assembly system of the OHL-KD eliminates expensive transport and lifting machinery that would otherwise be involved with a pre-assembled louver installation.

Vertical Outside Louvers are of heavy aluminium construction with either a double weather stop or 'eliminator' type vertical blades.

The Holyoake sound trap attachment is a modular assembly designed primarily to be attached to the rear of any Holyoake weather louver, to reduce the sound transmission to and from the environment.

The Holyoake Industries Louver Door System has been designed to incorporate all of the features that you could think of in an architectural door and still be compatible with our entire range of outside louvers.

The Louver Door System is robustly constructed in extruded aluminium box section to provide the strength required to hang a large louvre door. All of the on site fixings are designed to be concealed once the door has been installed. The doors are hung with high quality stainless steel hinges that have been selected to take the load of a large door.

Holyoake penthouses are designed and built to become a permanent part of the building. They maintain their attractive appearance and effective weather protection for many years as a result of their solid, extruded aluminium construction and careful workmanship.

These penthouses incorporate the 102mm horizontal outside louvers, with a choice of standard blade cross sections and screen mesh sizes. They are finished with mounting angles for easy and versatile mounting on a variety of roof curbs.
