Louver Opening Closing Roofs

Louver Opening and Closing Roofs.

Recently we have been designing a range of projects featuring Louver Opening Closing Roofs. Not always are we required to nominate a final manufacture we have reviewed a number of manufacturers within Melbourne Metro area. Our review included types of  Louver blades  available, benefits and design styles and limitations both related to louver and their related systems that we could recognise to advise our clients their possible design options. There are certainly some variation between suppliers that are worth considering beyond the general final cost of the project. In other words their not all the same.

Key issues seem to be

Material types of Blades – Colorbond or Aluminum appear to be the two selections available. We have been asked about clear (see through) but I have not seen an option to date.

Spans – Maximum Spans range from approx 3.6 meters to maximum 3.9 +/-. suppliers dependant Bottom line – wider blades seem to provide longer spans. Longer spans seem to encourage more blade defection (sagging). This factor to be considered in blade performance. We have found the need for extreme spans can be overcome with good design. Our preference is to ensure spans are within blades capacity.

Durability – Steel base (with Colorbond or coloured finish against Aluminium (raw or powder coated). Certainly Aluminium blades seem to be popularly favoured. Vergola, Straco for example and a range of other manufacturers still maintain Colorbond blades. The durability is not known but can only assume if installed per manufactures requirements then warranty indications will be achieved. Aluminium seems not to have rust and defection issues that colorbond web conversations suggests. Certainly not the only issue under review but certainly if your near the sea or if warranty of product limited this might be a factor to be considered.

Shape of Blade – shape of blades certainly can vary between manufacturer’s. This seems to a large degree a personal choice issue, although some of the wider blades clearly relate for span issues. No blade I reviewed was what I would call horrible. Frankly, if blade considered can tick off all the building issues then its down to which one appeals and cost.

Colour of Blades – Colorbond blades do seem to have a narrow range of colours available. This can vary between manufacturers – check what your manufacturer can offer as certainly it is generally restricted. Aluminium blades have not colour restrictions as they seem to be powder coated to order. This can help is matching a colour on existing building such as door or window colour. Having raised this issue, I personally favour lighter blade colours due to benefits of light bounce provided by lighter colours. Dark colours tend to close down the feel of the area.

Mechanism of Opening and Closing – the motors, sensors, connections (blades to turning components) are certainly a factor to be considered. The warranty’s all seem to be minimal so the cost to replace a motor in 5 years for example should be considered. Currently, we have only heard of minimal issues related to this factor with no manufacturer being a standout “good or bad” to our knowledge. My own feeling is if the system simple and easily maintained, then less possibilities for things to go wrong or to be costly to repair. Check the opening capacity of blades up to 90 , 120 or 180 degree. Some blades can open a full 180 degree and this I consider a benefit to controlling light.

Warranty – Certainly there does seem to be some variation between manufacturers with the best warranty I have reviewed for blades and pins being Totally Outdoors supplying Eclipse Opening and Closing Louver Blades.

Frames – Our main position on fames essentially comes down to visual outcome. Personally if considering the most expensive roof option (which louvers seem to be if fixed glass not considered) then to “knock up a cheap timber frame” may not offer the best outcome. The general options seem to be Colorbond and Aluminium in the sleek modern feel (I have viewed some some bulkheads in merbau – see top picture), bulkheads using conventional blue board rendered (adjacent picture) or some new hardboard options painted. No right or wrong on what selection you decide on except ensure it blends and adds to the visual outcome of the area you have envisaged. We have designed a range of all of the above.  Note: Note all suppliers offer a full range of frame options.

How can we assist – The Project Centre can provide drafting related to any manufacturer you may chose. There will be manufacturers engineering and specifications be required to ensure design / product requirements are in sync. Contact us to discuss your project.

Summary

The Louver Opening Closing Roof is an exceptional roof option if your outdoor area would benefit with the option of controlling the amount of light / shade / heat to both the outdoor area and possibly to the actual dwelling (i.e.: internal room) or public area (restaurant -internal section).

We hope we have provided a reasonable overview of main and important issues you might consider beyond just the final price of your project. Final cost does relate, as we know, very much to performance, durability and usability of the project. We would have loved to provide a tick off comparison but as products specifications and site situation vary it makes it somewhat difficult to review in that format.

We suggest review of web sites and general web forums may also assist you with choosing the right blade and builder for your project or why not contact us to design and provide advice to consider.
