Wall Ventilation

Refurbishment Weep Vent – G952

Core Vent – G900

Manthorpe Refurbishment Weep Vent – G952 Description
The Manthorpe G952 has been designed to provide retrospective ventilation to cavity walls where no or an insufficient amount of Weep Vents have been used. In addition the Manthorpe G952 can be used to ventilate plastered walls where standard weep vents are notoriously difficult to detail. The Manthorpe G952 can also be utilised in weatherboard in order to provide ventilation to combat isolated areas of mould inside the home.

The product is quick and easy to install and comes in a range of colours to suit all common brick and render finishes.

Further benefits of the product are that each unit is produced with louvered chevron grill which helps to protect against wind driven rain. The protruding drip feature on the front face of product directs moisture away from wall rather than down onto it which could lead to unsightly stains and damp patches.

Manthorpe Core Vent – G900 Description
The Manthorpe 5” Core Drill Vent is designed predominently for use when ventilating a gas appliance, although it can be used to supply general through-wall ventilation as well. The kit includes a cowl vent for exterior use, a louvre grille for interior use, a 350mm length of pipe duct and an optional anti-draught baffle which reduces the airflow and also the feel of a draught through the vent. Without the use of the anti-draught baffle, the free area of the vent is 100cm², enough to supply an appliance with a rated input of 27kW or 92,000 Btu/h. With the anti-draught baffle installed, the effective free area of the vent is reduced to 70cm² providing enough ventilation for an appliance with an input rating of 21kW or 71,500 Btu/h. The vent can easily be fitted in both refurb and new build situations with the use of a 5” (127mm) diameter core drill.
