Trimvent® 90 Hi Lift
Trimvent 90 Hi Lift is a semi-recessed aluminium slot ventilator that fits over a 16mm slot in a window and provides an Equivalent Area (EA) of up to 8600mm² when fitted with the Hi Flow canopy. The TV90 Hi Lift is ideal for both new build or refurbished situations using any window material, and is also available in a variety of colours.
The Hi Lift design improves the Trimvent range to offer increased ventilation. It gives optimum airflow (and therefore EA) utilising existing Trimvent slot sizes and vent lengths, making them 60% more efficient than previous models.
It has been specifically developed for recent revisions to Part F of the Building Regulations for Ventilation (England & Wales), is optimised for use with the Scottish Technical Standards and to improve performance for requirements throughout the UK and Europe.
The Trimvent 90 range of trickle ventilators has been specified and fitted on millions of windows throughout the UK and mainland Europe over the last 35 years.
