Premium Trickle Vent - Slot/Frame Vent for uPVC Window 400mm - White 5 Pack

Product Information

Handlestore only supply vents that can be screw fixed onto your existing frame. You may have screw-fixing points already that can be re-utilised, or it is more likely that you will have to drill two new holes. Drilling into a plastic frame is easy but you need to ensure that you have marked the position of the fixing points carefully. The best way to do this is to hold the vent in its position and then drop a pencil into the fixing holes to make a mark. All of our vents are provided with the correct screws for uPVC frames but you will need to use a 2mm drill for the screw to tighten correctly. Airflow performance: 4069mm² Equivalent Area - independently tested in accordance with BS 13141-1:2019 We should point out that there may also be extra difficulty with uPVC if there is a metal reinforcement section inside the hollow profile of the frame. This can be the case but not always and the metal can be either aluminium or galvanised steel. The metal sections tend to be quite thin but the galvanised surface of steel is difficult to drill through. The new fixing centres are pulling the plastic vent down flat but under tension. Release and re-position carefully. Challenge: Including these additional ventilation components requires adjustments in manufacturing processes, sourcing of new materials, and compliance with quality standards. These factors contribute to higher production costs, which may ultimately be passed on to consumers, causing dissatisfaction.

There are two options to consider when positioning the vents on your window. The first is to put them on the outer frame of the window at the very top of the window or alternatively to position them at the head of the opening window itself. The latter may be easier to do as you can take the window off by the hinges and place the complete unit on a table or bench to carry out the work. It is also easier to assess whether any reinforcement is present within the window unit (uPVC) by withdrawing some of the screws to view the screw type. Drill point screws are used for reinforcement metal and self tappers are most likely to be for uPVC only.All vents are provided with two cover caps to disguise the screws and finish off the installation by simply pushing into place. The plastic vent is so long it doesn't fit perfectly flat onto the surface of the window. In that case consider the aluminium vents which are more rigid and sturdy. The windows you have will require slots cutting through them that are the correct dimensions. By drilling holes this will not allow enough air through because of the bridges between the holes.

Once your item has been returned, we will inspect it and take the necessary action as soon as possible.The basis of these window ventilators is to pass air through the frame and to do this you will need to form a slot within the tolerances shown. This can be done on uPVC or timber windows but aluminium or steel windows is not advisable. The vents can then be screwed to the frame and operated quite simply. The overall length of the slot against the screw fixing points size (ensure there is enough room past the slot at each end to get a screw into the frame. When you take the existing vent off the window you will see a slot or two slots cut through your window. Ideal for use on new build properties or window refurbishment projects in existing properties and suitable to be used on timber, aluminium, or PVCu windows. Take the window out of the frame if it is easier particularly if you decide the vent is the best option to place the vent otherwise it will be done in the head of the window where there is no interference from the glass.

It is recommended that you screw the vent down into position using a hand screwdriver not a drill or any other mechanically/electrically operated device. The screws will appear quite tight but this is important to cut a suitable thread into the plastic. Provided you don’t over-tighten the screws the vent will be adequately fixed.
