Packed: 1
- Designed to provide a clear airflow passage to a void beneath an insulated suspended floor - 8,000mm² airflow
- Current and future requirements of Part L of the Building Regulations along with other standards and regulations have led to an increase in the depth of thermal insulation in suspended floors along with an increase in cavity widths to accommodate greater amounts of cavity wall insulation
- This has meant that clear access to an underfloor void may be as far as 6 or 7 brick courses (525mm) below the level of an airbrick and potentially as much as 350mm from the outer face of the external leaf - traditional telescopic underfloor ventilators would not be able to achieve this without the use of additional vertical and horizontal extension sleeves
- The dual extended underfloor vent offers vertical telescopic adjustment of between 5 and 8 brick courses (318mm-575mm) without the need for an extension sleeve
- The horizontal outlet is long enough to bridge through an overall wall thickness of 350mm without the need for an additional extension
- The front aperture is designed for use with a combination airbrick or it can be used in conjunction with a traditional clay airbrick, although this would reduce the overall airflow through the system
- Regulations - BRE Digest 17, BRE Digest 262, Building Regulations C4, NHBC Standards 5.2 and BS 5250:2011 Control of Condensation in Building

Worth it!
Size: Queen(Pack of 2)
These pillows are amazing and very soft and comfortable. They came nicely packaged and I let them sit out for just a few hours before using them and that was plenty of time! They come with the cooling cover and fit a standard queen sized pillowcase. The material expands well and does not have any weird smells. 10/10 well worth the price.

Miracle pillow
Size: Standard(Pack of 2)
Best pillow I’ve ever had. I have been using this since December 2024 and it still hasn’t gotten flat. It is amazingly comfortable and solves all my neck issues for a side sleeper. My head never gets hot either. I’ve recommended this to my friends and they’ve had success with it as well.
