    Moisture Ventilated Cavity Barrier WB or RS/WB/W gives a complete smoke seal. Place a tube and rubber grommets through the course between the brick and block mortar. Also, use with an aluminium rainscreen by drilling a hole in the aluminium to allow the tube to go through. Drilled hole size approx 10mm. Additionally, the moisture and smoke Cavity Barrier can have a self-draining and airflow system ( VWBG ). Tubes fix into the barrier unit and set into the mortar, allowing moisture to drain to the external area. Also allows free airflow into the cavity area.

    All of our 'in stock' product orders will be shipped same day, as long as the order has been processed before 3pm - this is simply to be in a position to catch the courier pickups.

    Some of couriers are explicit in their non-liquid deliveries so if you have ordered a mixture of ambient and liquid products your order has to be split across two couriers. These are lead by courier company policies, however the courier selection was done of price and so you can be safe in the knowledge that you will be getting the most competitive delivery prices around. 

    We deliver across the Island of Ireland and aim for 48/72hrs deliveries on all our orders. If you order a product that is 'out of stock' we will get them shipped by our supplier, Envirograf UK over night for our next days deliveries.
