Slimline Tricklevent

The Slimline Ventilator will provide Trickle Ventilation in accordance with the Building Regulations 2000: Part F: Approved Document F1 October 2010 and Scottish Building Regulations October 2011 Standard 3.14.

The product is specifically designed for “Through Profile” PVC-U applications using a 10 mm routered slot, and is available in two sizes. All ventilators are “Clip” fixed with the advantage of rapid fitting to profiles.

The products key features are as follows:

  • Spring Clip fitting (No Screws) (Saves over 1 minute per window to install)
  • Unique closure mechanism provides for adjustable ventilation with a positive action
  • BBA and LABC Certification on most versions
  • Sash window application – “Offset” clips are available
  • Clip fixed so no end caps (to be lost)
  • Available in 100’s of colour options and combinations

The product consists of an internal ventilator with adjustable closures to regulate incoming air flow and an external canopy with integral fly screen.

Internal ventilator
This is injection moulded in PVC-U, with UV resistant Acetal spring clips that enable the ventilators to be firmly snapped into the routered slot in the profile. The installation of this vent provides time cost savings when compared with ‘screw fitting’ alternatives.

The closure plate has a positive action and multiple units in the 4000 version provide control of airflow.

A variety of custom fixing clips are available to offset the ventilator vertically relative to the 10mm slot for applications such as sash windows, where space is at a premium. These give offsets of +/- 2mm.

External canopy
This is complimentary to the interior unit and features the same materials and fixing methods. The canopy has an integral fly screen. A flat grill is available.

Materials of construction
Internal and external units are primarily moulded in UV stabilised PVC-U. The spring fixing clips are in UV stabilised Acetal. Suppliers data sheets for these polymers are available on request.

All tricklevent colours are available boxed as bagged sets or bulk packed “pick n mix”.

Bagged sets – The vent (internal) and canopy (external) are bagged and are both the same colour, normally 50 sets per box.

Benefit; Sets are easy to pick and ship with each window. Typically, vents can be taped to windows or added to the hardware box that accompanies each delivery.

Colour on white sets – The vent (internal) and canopy (external) are sold as sets (white internal vent with a coloured external canopy), normally 50 sets per box.

Benefit: No need to buy two sets of vents, (a white set and a colour set) then dispose of the excess parts, so half price?

Specials – If you need a particular colour mix, these are normally made to order with 50 bagged sets per box. Contact customer service for advice on availability.

Bulk packed – The vent (internal) or canopy (external) are sold separately (one colour only), normally 100 parts per box.

Benefit: This allows for a “pick n mix” option on the production line. This allows more effective purchasing on volumes and “special” colours whilst being easily adaptable for colour on white. Buy more of the colours you use most of at better prices and carry minimal stocks of low volume use or special colours.
