AVOID COMMON MISTAKES The biggest error we see when it comes to extract fans is not the fan directly, but the ducting. Contractors rarely credit ducting with the attention it deserves, but it can make or break any ventilation system, even something as seemingly simple as an etra fan fi tted as a through- the-wall installation.


The biggest ‘crime’ here for installers is to make the mistake of using fl eible instead of rigid ducting. Flexible duct work causes a lot more air resistance and


can be damaged or even crushed easily. The next mistake to avoid is to use the wrong size ducting for the fan. If the fan has a 150 mm diameter spigot, use 150 mm ducting! We repeatedly see installations where the ducting used is smaller than that of the spigot, and reducers have been used to make it work. But it doesn’t work – at least, not well – as this causes signifi cant air resistance and problems with the performance of the fan. In a similar vein, ensure you have the appropriately sized tile vent.


Both fl eible ducting and incorrectly sized ducting will also lead to a much noisier fan than is necessary, and your customer won’t thank you for that! Also when it comes to ducting, it’s best practice to keep ducting as short and straight as possible as ducting creates air resistance, which reduces airfl ow. Lastly, it might seem obvious, but you’d be surprised how often this mistake is made: if you are drilling through an external wall, make sure that the core drill is the right size based on the fan spigot. You don’t want it too small as otherwise the fan wont fi t through the hole, but clearly if it’s too big you’ll have to do some remedial work to the wall.

Unilin Flooring announces certifi ed pre-consumer recycled content for its dryback and engineered vinyl fl ooring for housing and commercial projects made under the Quick-Step and Moduleo brands. Unilin Flooring, a division of Unilin, specialises in the production of laminate, wood and vinyl fl oors for housing and commercial interiors. As part of the Unilin One Home sustainability strategy which aligns with SBTi (Science Based Targets initiative) near-term targets, it has undergone an analysis of pre-consumer recycled content within its vinyl fl oors made at its Avelgem, Belgium production facility. Conducted by third-party certifi cation body SCS Global Services, the analysis has calculated the total content of pre-consumer recycled content used in dryback, loose lay and engineered vinyl fl oors made under the Quick-Step and Moduleo brands. Under the analysis, pre-consumer recycled content is defi ned as: recycled materials from other industrial processes, including internal cutting waste, reprocessed into raw materials. For dryback and loose lay vinyl fl oors, such as those in the Moduleo Roots 55, Moduleo Moods and Moduleo Intoo loose lay collections, a minimum 21% pre-consumer recycled content is used (SCS-RC-20324). At least 22% pre- consumer recycled content can be found in engineered vinyl fl oors from Quick-Step Alpha Vinyl and Moduleo LayRed.
