Trickle Ventilators
Are designed to allow the passage of stale and fresh air through the window or door, the position of the ventilator (internal operation) and canopy (external) are usually on the top of the opening sash or the top of the frame. Every system is different, and you should enquire and ask the question, should the vents be required.
Each type of vent will have different EQ requirements (Equivalent Area) to allow the ait to pass through accordingly to the room size requirements. Several designs are available but we utilise the product from Titon and these can be found here http://www.titon.co.uk/pages/products/ventilators.php
These come in standard colours and they may not match your chosen colour, we try and match as best as possible but if not, then it is important to know, we do not offer custom colours out with the standards.
The product we use is Trimvent® 4000 Hi Lift when possible, we may use a lower model dependant on window size.
