Certificate type
This Vent / Aerator is designed to help remove water vapour that forms between the roof slab and the waterproof roofing felt. Allows hot air to escape from between the roof slab and the waterproofing.
Application
Welded PVC aerator / vent to fit onto concrete slab for single ply membranes.
Description
Tough and durable vent, designed to help aerate concrete slabs and allow the structure to breathe.
Features and benefits:
- It draws moisture away from a concrete slab and is placed onto the bare concrete beneath the waterproofing membrane and insulation.
- Bonded by using hot air gun (not direct contact to a flame).
- The membrane is welded to the top of the base of the vent, creating a flue which helps to draw vapour out of the concrete.
- There are a series of ribs along the underside of the round base plate which encourage the movement of vapour along the base and into the flue and also act to alleviate any hot air which might appear between the slab and the membrane.
- The top of the flue has three lateral holes to allow the vapour to escape into the atmosphere.
- It is covered by a hood which overlaps the internal holes, preventing rainwater entering the system but still allowing the passage of vapour.

Height | 160 mm. Manufacturer guidanceThe shorter, broader vent can be used for deck areas where a shorter pipe is required. The extra-long vent pipe may be required for areas where some sort of covering is placed onto the deck and the hood needs to be exposed. |
Hood | Manufacturer's standard. Guidance for specification option: Black round cap. ESTRAER®. Guidance for specification option: Two conical funnels. Manufacturer guidanceThe ESTRAER® funnel shaped hood comprises two conical funnels which join up at a central hole at the top of pipe. It creates extra suction on the pipe, helping to draw out a greater amount of vapour and air from the concrete. For use where the concrete deck and insulation needs to be aerated and ventilated. |
Sustainability data
Contains Red List materials | Yes Manufacturer guidancePVC roof outlets themselves are not specifically called out on the "Red List," but since they are made from polyvinyl chloride (PVC), they fall under the general advisement against using PVC in sustainable building practices. The Living Building Challenge, for instance, lists PVC as a Red List material due to its environmental and health impacts during production, use, and disposal. This includes the release of harmful chemicals and pollutants. |

Recyclability | 100 Manufacturer guidancePVC can be recycled through mechanical recycling processes, where the material is ground into small chips or pellets, which are then cleaned, processed, and remelted to form new PVC products. However, recycling PVC can be complex and costly due to the presence of additives like plasticizers, stabilizers, and fillers that are often used in PVC products. These additives can make it difficult to recycle PVC with other types of plastics or even other types of PVC. |
