Ventilation is necessary for some types of primary glazing, whether for regular airflow or controlling condensation.
Having operational secondary glazing units can be integral to this.
Our lower and upper vertical sliding sash units allow easy access to your primary glazing, to allow regular ventilation, and are an ideal solution for sash primary windows. These are particularly useful in kitchens, bathrooms and bedrooms where regular airflow is essential.
Additionally, Storm manufactures horizontal sliding units which can be used for casement style windows (inward or outward opening) and allow a controlled airflow, giving easy access to clean and maintain the primary windows.
Regular ventilation should be considered to assist with controlling condensation, damp and mould which will affect the fabric of your building along with your health.
