As stated in Part F 2009 of the building regulations a habitable room must have a background ventilator with equivalent area of 5000mm sq, this increases by 40% in the case of a house with a airtightness value lower than 5 m3 (h/m2), bringing the requirement for a habitable room to 7000mm sq for reasonably airtight homes.
With some of the products on the market it can be difficult to meet this with a single vent, however with Rytons Super Acoustic Controllable LookRyt® AirCore® 8,500mm squared equivalent area can be achieved with one 125mm diameter wall vent.
ALL THE RYTONS PRODUCT ARE SUBJECT TO CUSTOM CHARGES (IMPORTED FROM UK).

F.A.Q.
>
Do I need an extension piece? The extension piece is an extra fitting that easily attaches to the wall vent. It is only required if the depth of the wall exceeds 350mm.
Will the vent reduce sound from inside to outside as well as from outside to inside? The BRE state that ‘reciprocity’ applies to the vents. That is, the third-octave values for sound reduction index are the same in both directions (out to in and in to out).
Are the wall vents only available in white? No, the external grille comes with a choice of colours such as, Terracotta, Buff/Sand & White.
Can I collect? No, collection is not available.
Can I buy individual parts/components? No, the products are sold all-inclusive so individual components can’t be sold separately.
What is the level of noise reduced i.e. 43/50dB? As can be seen from the accompanying chart, this level of noise can be considered as a standard conversation, what you might not consider loud, but noise nonetheless. Although this may not seem like much, it reduces the level of what you could consider loud noise quite noticeably. In all our years of supplying this product, we’ve never had a complaint about the acoustic noise reduction not living up to expectations.
Do you provide installation? No, we do not provide installation for ventilation products.
How to install? The installation sheet can be found beneath the product description. The installation process is quick and easy to follow, with illustrations provided to avoid confusion.
Can it be mounted on a ceiling? No, this product was manufactured specifically for through wall ventilation and should not be installed through a ceiling.
Is it suitable for stoves? No, this product should not be installed near a stove as it does not comply with the relevant building regulations for stove ventilation.
Is there a 4 inch available? No. With respect to the relevant building regulations, the minimum allowable duct diameter for this type of ventilation product is 5 inch (125mm).
Can it be partially opened? Yes, the amount the vent opens can be controlled by the user and isn’t restricted to either fully opened or fully closed.
Can it be fully closed? No, the vent will always allow for trickle ventilation.
Can extension pieces be trimmed to length? Yes, however, extension pieces are only required if the wall the vent passes through measures more than 350mm in thickness.
Do I need a cowl? A cowl is used to reduce the effect of heavy winds on an air vent. It isn’t necessary, but may be required if the outlet of the installed vent is on a frequently windy facing side of the building.
