Packed: 1
- Designed to provide a clear airflow passage to a void beneath an insulated suspended floor - 8,000mmΒ² 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

Not for chewers
Size: 8 Inch, Color: Yellow, Size: 8 Inch, Color: Yellow
My dog managed to pop this and completely chew through it in a matter of 4 days. It was definitely cute and she loved the size of it but with her chewing all the way to the core we have to get rid of it. I thought it was a good material but I guess I was wrong. Kind of sad considering the money spent only lasted 4 days

Great dog toy
Size: 8 Inch, Color: Pink
The amount of stupid and cute these dogs look like when they shake this ball and smack their own faces! It took a hot second for either dog to understand where to bite on the ball, but now that they do, they both will play with it for a while. Great purchase, came with a pump to blow the ball up.

Great toy to play fetch with the dogs.
Color: Black/White, Size: Large
These balls are a great dog toy to play fetch with your dogs. This not the first ball I have gotten for the dogs. Just the right size and weight for medium sized dogs. I have less concerns about them possibly choking on these soccer balls versus tennis balls. So I can leave them out for them to play with. The are easy to inflate using the included pump. My only concern is the durability of the straps as my dogs have almost torn off one the straps of the previous ball I purchased.

A must have for my pup! I have bought this at least 5 times. She eventually pops them and I need a new one. It's an amazing toy that she can thrash and we can play fetch with

Westie LOVES this toy
Color: U.S.A, Size: Medium
My pup (Westie) adores this toy. This is actually our second one. The ball itself is resistant but the straps will be obliterated. Would definitely recommend! Totally worth the price!
