Wallbarn Standard Black Plastic Cap for TPE Vents 140mm High

Drainage Superstore

This 140mm high Wallbarn Standard Black Plastic Cap is designed for TPE Vents. Otherwise known as aerators, Wallbarn TPE vents facilitate aeration beneath a concrete slab and promote proper ventilation within the structure. Constructed from TPE, a plastic/rubber composite, they are compatible with bituminous waterproofing systems.In any concrete structure, there will be a degree of moisture retained within its mass following construction. After the roof is waterproofed, it is crucial to provide a means for this residual moisture to escape the system. Without it, there™s a potential that built-up moisture will protrude from the top of the structure, causing bubbles, blisters and even rupture that will affect the waterproof seal. Vents effectively redirect this moisture away from the concrete slab.Features & Benefits: Wallbarn Standard Black Plastic Cap for TPE Vents - 140mm High, 140mm height, 75mm diameter of the cap at the bottom (where it slots onto the pipe), 82mm diameter of the funnels at each side, Made from TPE plastic/rubber composite, For use with TPE vents, Compatible with bituminous waterproofing systemsPositioned onto the exposed concrete surface beneath the waterproofing membrane and insulation, the membrane is applied over the base of the vent, creating a flue™ that facilitates the evacuation of vapour from the concrete. The round base plate (or flange) is equipped with a series of ribs underneath, promoting the flow of vapour along the base and into the tube (or flue). It serves to mitigate any buildup of hot air between the slab and the membrane, which is often evident through blistering and bubbling of the membrane material..

Wallbarn TPE vents, also called aerators, are designed to help aerate the concrete slab beneath, and help the structure to breathe. These vents are manufactured from TPE, a plastic / rubber compound. They are suitable for bituminous waterproofing systems. All concrete will retain an element of moisture within its mass after the construction process, and it is important that once the roof is waterproofed, this moisture has a way to escape the system, otherwise there is a risk that this retained moisture will build up and possibly bulge out of the top of the structure and cause the waterproof seal to bubble, blister or even burst.     The vent is designed to draw this moisture away from the concrete slab. It is placed onto the bare concrete beneath the waterproofing membrane and insulation. The membrane will then be applied over the base of the vent. This creates a flue which helps to draw the vapour out of the concrete. There are a series of ribs along the underside of the round base plate (or flange) and this encourages the movement of vapour along the base and into the tube (or flue). It also acts to alleviate any hot air which might appear between the slab and the membrane, often evidenced by blistering and bubbling of the membrane. Properties Height: 140mm. Diameter of the cap at the bottom (where is slots onto the pipe): 75mm. Diameter of the funnels at each side: 82mm. Material: Plastic.. Wallbarn Standard Black Plastic Cap for TPE Vents - 140mm High
