Entrapped Humidity Discharged By Effective Sub floor Ventilation

When sub floor ventilation is absent or inadequate, off-gassing from organic substances enters the habitable area and manifests itself by a pungent odour or a musty smell which decreases the air quality inside the home and excess humidity levels can encourage termites as they are attracted to moisture.

External Cement Rendering and the Impact on Sub floor Ventilation

It is understandable that the look of cement rendering can be quite attractive when finished, as the wall appearennce seem quite clean. However in some cases when this is done it is easy to render over existing passive vents which will make the minimal sub floor ventilation non-existant.

The ‘Standard’ That Established The Envirofan Quad Fan System

From 2001 Envirofan introduced the Quad fan system. The uniqueness about Envirofan products is the R & D that went into fan mechanism before its release into the marketplace from the 1980’s.

Sub-Floor Ventilation and the City (Melbourne, Sydney, Brisbane) – Is it a Good Idea?

In the cities such as Melbourne, Sydney or Brisbane, land-space is maximised by reducing block sizes and opting for medium to high density dwellings. This creates a challenge for effective sub-floor ventilation where surrounding buildings can inhibit natural air-flow through passive vents or neighbours being in such close proximity that the noise (or db rating) from certain types of fan-forced ventilation systems can be quite disturbing.

DIY Passive Vents or Fan-Forced Sub-Floor Ventilation?

TonyS_EF10-4-Installed-22-3-14-#4

Before the invention of fan-forced sub-floor ventilation systems, passive ventilation was the normal practice in home building. But do they adequately create cross-flow ventilation in the sub-floor area? This is something to consider before cutting brickwork and embarking on passive vents or fan-forced sub-floor ventilation systems.
