Visqueen VT024A Air Brick Black RS061033

Product Overview:

Visqueen Airbricks are manufactured from UV stabilized polypropylene and are available in Terracotta and Black. The airbrick replaces an external masonry brick. It incorporates a front mounted louvered grill to permit airflow while blocking out wind driven rain and prohibiting large insects from gaining access.

The airbrick, vent and extension sleeve are sold separately.

When combined with the vent (with or without the extension sleeve), each airbrick provides a free air flow capacity of 6450mm².

Features & benefits

• Easy to install - functional solution for exhausting ground gases from underfloor voids
• Integral grille - prevents movement of vermin through vent
• Robust material - resistant to decay
• Purpose made system components - no airflow restriction through vent

Usage

• Visqueen Adjustable Z Vent and Airbrick system is used within external masonry cavity wall constructions to provide a clear airfow passage to the void beneath precast suspended segmental ground foors e.g. beam and block. The system is used to achieve a passive subfoor ventilation system in accordance with BS8485:2015 + A1:2019, efectively diluting any hazardous ground gases accumulating in the underfoor void.
• The telescopic feature enables the vent to adjust vertically within the cavity to between three and fve brick courses (225mm and 375mm).
• The airbrick replaces individual masonry bricks in the external leaf.
• The system includes a Visqueen Extension Sleeve which increases the adjustment of the vertical portion of the vent by a further
• two brick courses (150mm). Additional sleeves can be used to extend the coursing indefnitely. The extension sleeves can also be
• used to extend the horizontal portion of the vent e.g. for wider cavity applications.
