## Overview

The Perma-Vent Condensation Control Vent by Permagard Products Ltd offers a passive, maintenance-free ventilation solution featuring a vapour permeable membrane to prevent condensation and draughts. Designed for easy installation with a core cutter, it boasts over 15 years of proven performance, making it a reliable choice for long-term indoor air quality improvement.

## Description

Product description               The environmentally friendly Perma-Vent contains no moving parts and requires no maintenance. It works on the scientific principle that when the room temperature and humidity are greater internally than those externally moist air is ventilated outside the building due to vapour air differences. The Perma-Vent contains a vapour permeable membrane, this means vapour is allowed out of the building without allowing a draught back inside. The unit is easily and economically installed using a 4.25” (108mm) core cutter, positioned wherever condensation/mould is most prevalent. The thickness of the wall does not present a problem the standard unit is supplied with a 13.5" (350mm) long ventral core which will accommodate most properties. The unit is designed to be very unobtrusive, with a 6" (152mm) internal white plastic grill. Externally all that can be seen is a 6" white plastic external grille. It is possible in severe instances that a more advanced condensation control unit will be required to remedy the condensation. However the installation of a Perma-Vent is a simple, inexpensive, starting point to tackle the local problems of condensation and mould. The external diameter of the tube is 104mm so the core should be cut larger eg. 4.25” (108mm).

## Questions & Answers

**Q: Is the "permeable layer in the tube just insulation?**
A: The permeable layer in the tube is not insulation as such but a wadding material. Insulation would be too dense whereas the wadding will stop the draft but still let the correct amount of air flow/vapour through.

**Q: What's the maximum wall width that's this product will fit??**
A: 350mm

**Q: What height should this be fitted at?**
A: I've fitted my  one 25 cm from ceiling in bedroom and its solved my condensation problem.

**Q: Moonstone how did it work our, im thinkibg of putting one in the attic**
A: Mine has worked wonders my dad drilled the whole to install ..not had any issues since
