Engineered with a louvred chevron grill and drip rib, these vents protect against wind-driven rain and direct moisture away from walls, preventing damp and unsightly stains.

## Description

White Refurbishment Weep Vents Pack of 10 Quick and easy to install in a 25mm drill hole. Louvred chevron grill which protects against wind and driving rain. External flange covers any damage to the substitute caused by the drill. Drip rib ensures clean moisture run off. Suitable for commercial and domestic use. Can be used on brick or rendered walls. Provides 260mm² of ventilation per unit. Length: 85mm. Diameter: 25mm. Satisfies NHBC Standards. Available in a range of colours and quantities in our shop. The 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 G952 can be used to ventilate rendered wall where standard weep vents are notoriously difficult to detail. 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 louvred 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.

Review: Nice fit - Good quality and with plenty of space for ventilation. I was a bit unsure of it but it is perfect for a garage conversion.
Review: Ideal for the job - Ideal for what I needed for trickle vents around the house. It has stopped a few bits of black mould appearing behind furniture.

## Questions & Answers

**Q: Can you put  these into 100mm concrete blocks, is it a problem if it doesn’t cover the whole length of the drilled hole?**
A: Hi,

A: Actual brick
Fitting Instructions
Preparation
Mark out the locations for the vents and drill a 25mm diameter hole through the external leaf of the wall into the
cavity at a slight upward angle at these points. Ensure that the hole is clear and free of debris before proceeding.
Installation
Align the tube with the hole, making sure to have the chevrons of the front grill pointing upward and the flat edge of
the drip feature horizontal, running parallel with the run of the wall. Push the vent firmly into the hole using the palm
of your hand until the back face of the flange sits flush against the substrate. As the ribs along the length of the tube
grip to hold the product in position it may require more force to push the vent into the hole, it is acceptable to gently
tap the vent into position using a rubber mallet.
Requirements
The vents can be positioned at high or low level to suit the required detail, and should be placed at both high and
low level to achieve a cross flow venitilated cavity if required. To suit the following requirements:
NHBC Standards 2008 - 650mm² free airflow every 1.2m - Space the G952 at 480mm centres.
Scottish Building Regulations 2007 - 300mm² free airflow every 1.2m - Space the G952 at 1m centres

**Q: Hi. Do these vents have an insect mesh or grille?.**
A: They do not have an insect mesh however the louvered grill is designed to deter insects from entering the cavity.
Thank you for your question.
