AIR CONDITIONING, COOLING & VENTILATION
Lastly, be prepared! Site related constraints may change, and the duct drawing may need to alter. If you have to make changes, re calculate the air flow rates and, where necessary, change product accordingly. For example, if you must include a bend where one didn’t exist before, consider using something like a Domus Greenline Bend which has been cleverly engineered to reduce duct bend resistance by up to 60%.
Stick to the plan when it comes to installation
Once your duct drawing is finalised and the ducting is ready to be installed, be sure to stick to it on site. It’s not uncommon for installers to try save time and money by making the duct runs simpler or swapping rigid ducting for flexible ducting at final connections or around obstructions. All that hard work and carefully thought out planning compromised at the last post!
When it comes to installation of extract fans, check if wall and in-room installation kits are available as these will provide all the necessary parts to fit the fan – including ducting and grilles – for a swift, straightforward installation. Be sure to fit ducting insulation and
By far the easiest option though is to outsource the drawing. Most manufacturers, Domus Ventilation included, will provide a system drawing free of charge, along with duct take- offs and estimations.
firestopping products, as laid out in Building Regulations. Insulation is required where the ducting passes through unheated areas and voids, such as loft spaces. Firestopping products are necessary whenever a hole is made in a compartment wall for plastic ventilation ducting to pass through. In addition, non-combustible air bricks, such as Domus Ventilation’s Solis Air
Brick, must be used where ductwork penetrates through the external cavity when above 18m in England and 11m in Scotland.
Take care of your ducting and it will take care of you
Getting the ducting right really is one of the most important aspects of a residential ventilation system, yet it’s frequently the most overlooked and undervalued. By taking the time to consider your ducting products, where they go and how they are installed, you are more than half way to ensuring a good ventilation system that is Building Regulations compliant.
Your safety, our priority.
