All of our PVCu double glazed windows allow for background ventilation. This is essential during the cold months to prevent condensation building up within your home. Many customers opt for trickle vents - the long thin slot vents found on almost all new windows in newbuild properties. These are closeable when not needed, but it is recommended that they are all left open at all times. These provide draught free ventilation.
Some customers who are replacing their windows in an existing installation may not want to see the trickle vents. Therefore, all of our windows are fitted with a night vent facility. These work in much the same way as slot vents, but without them being needed. The window is opened slightly and then locked in this position. Again this gives draught free ventilation and is also extremely secure. Either form of background ventilation will help remove condensation whilst leaving the house secure as normal.
