The G965 Dual Extended Telescopic Underfloor Void Ventilator is designed to provide a clear airflow passage to a void beneath an insulated suspended floor.
Due to modern methods of construction, increased depths of thermal insulation are being used in suspended floors along with an ever-growing width of wall cavities to accommodate the greater amounts of insulation placed within them, mainly driven by Part L of the Building Regulations and other standards.
This has resulted in clear access vertically to the underfloor void being as much as 6 or 7 brick courses (525mm) below the level of an airbrick and potentially as much as 350mm horizontally from the outer face of the external leaf.
The G965 Dual Extended Telescopic Underfloor Vent eliminates the need for vertical extension sleeves, in most modern details.
The Underfloor Vent is manufactured to offer the greatest vertical telescopic adjustment on the market between 5-8 brick courses, the standard being 3-5, the horizontal outlet can bridge an overall wall thickness of 350mm, so no additional extensions are required, in most modern details, keeping installation quick, simple and free of error.
Designed to meet the requirements of the relevant Building Regulations Approved Document C 4.19, NHBC Standards 5.2.10, BS5250:2011 and BRE guidance, the product is of a strong and durable nature for added assurance and integrity once in position.
