Trimvent® Select Xtra S13 is a surface mounted plastic slot ventilator that fits over a 13mm slot in a window and provides an Equivalent Area (EA) of 2000mm2, 4400mm2 or 5000mm2. It can be fitted with an XC13 canopy or GS22 grille.
The XS13 is a direct replacement for the S13 range, using the same slot measurements but offering a much greater airflow and Equivalent Area.
The XS13 is ideal for both new build and refurbishment situations using any window material, and is available in a variety of colours.
The Xtra design improves the Trimvent® Select range to offer increased ventilation. It gives optimum airflow (and therefore EA) utilising existing slot sizes and vent lengths. It has been specifically developed to meet the recent 2022 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.
Trimvent® Select ventilators have been specified and fitted on tens of millions of windows throughout the UK and mainland Europe over the last 20 years
