Windows and doors play an important part in providing ventilation in a home, whether it’s opening a window for ‘purge’ ventilation or through the use of trickle vents for controlled and secure background ventilation.
XXX’s ventilation range includes full whole house systems, which have come to the fore due to the emphasis on improved energy efficiency, as well as trickle vents and window opening systems.
Replacement windows are fitted to reduce air leakage and insulate from the cold outside. It is essential to fit trickle ventilators in these circumstances, as they will compensate for the reduction in accidental air leakage around old or poorly fitted frames and glass.
