Frequently Asked Questions
Waterproofing is provided by the closed cell foam that is pre-installed to the base of the louvre. When pulled tight and embedded into the sheet, a watertight seal is created.
Normal ridges are designed to sit flat along the sheets and in between the ribs, the valleys are ‘turned up’. This results in the air being completely restricted. The Vent-A-Roof® ridge is folded differently so that an air gap is created to release the hot air from the roof space efficiently.
NO. Leave the sheets straight and ensure sheets are laid straight. The weather proofing is performed by the closed cell, built-in foam at the base of the louvre.
Scribing ridges is recommended from manufacturers due to wind-driven rain. The Vent-A-Roof® system has been tested to 177km/hr wind-driven rain with flawless results. Therefore, there is no requirement to scribe.
Just like a whirlybird, the sarking across the ventilated area needs to be cut back or simply installed to the top batten. If looking at sarking as a BAL measure, remember that the Vent-A-Roof® system is BAL 40 certified.
The louvres themselves can be installed at approximately 30LM/hour for a team of two installers.
No, the Vent-A-Roof® ridge is made with an air gap. The roll- top ridge is made as a standard size and available directly through Lysaght® for new build residential, however all other applications are custom made. Contact us for more information.
Yes, as the product comes in 1.5 metre lengths, we recommend installing in sections of at least 3 metres, however the product can be cut to suit the roof requirements.
Eave vents are not required for the product to work, however just like whirlybirds, it does make the product more efficient.
