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. Continue reading “Entrapped Humidity Discharged By Effective Sub floor Ventilation”
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. It made Envirofan or Solarfan as it was known at the time, very credible as the test process was carried out by UNSW Consulting/Unisearch. This established the standard for sub-floor ventilation systems.

Joining of Low Voltage Cable for Sub-Floor Ventilation Installations
In connecting Envirofan sub-floor ventilation systems various joining methods have been adopted.

Should Humidistats Be Used In Sub-Floor Ventilation Installations
Since the implementation of fan-forced sub floor ventilation systems the question does arise should humidistats be used in sub floor ventilation installations.

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.
The Recipe for a Great 12v Sub-Floor Ventilation System
For a great product to eventuate there must be a good concept; as was the case with the idea of a Solarfan 12v sub-floor ventilation system. We can compare the evolution of fan-forced sub-floor ventilation against the humble kitchen oven.

Is Sub-Floor Ventilation a One-Part Solution for a Damp Sub-Floor?
Sub-floor ventilation is one solution to a damp sub floor but it should not held as a panacea for all sub-floor damp issues. Why?

Pest Management and the Sub-Floor Ventilation Relationship
Pest management companies, as part as there termite control regime are recognising the need for sub-floor ventilation. The most effective sub-floor ventilation is the combined use of passive and active ventilation systems. Over the years passive vents have improved to include high flow vents, up from the old terracotta vent, which are a better proposition.

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