Ventilating your home / Ceiling & Wall Vents

Ventilating your home with Ceiling & Wall Vents

There are three types of ceiling vents, and you will have seen two types,….. those that are specifically designed to be used in ducted air conditioning systems, and those sold in hardware stores.

95% of the ceiling vents sold in hardware stores are vents priced for the naive consumer who knows next to nothing about what he/she is attempting to do. The others will likely have a short use by date especially if moving parts are involved.

The type used in air conditioning are designed for air delivery under pressure, normally a set and forget unit provided with the package.
They are not designed for atmospheric natural ventilation, so whereas the name may be the same it’s design function is not, but like beliefs, you’re entitled to believe as you choose.

The hardware store type ceiling vent or wall vent is a product providing the bare minimum in performance and reliability at a price, here again, again believe as you choose, it’s your money.

A vent with very small holes is guaranteed to require constant cleaning to free it of dust adhesion creating a high resistance to air flow.
The type you don’t see are those designed and constructed to be adjustable, with long life, good flow efficiency and low resistance, being the most suited to the purpose of natural ventilation particularly in the home.

A high efficiency, low resistance, ceiling vent is not only serviceable and adjustable, but is also a precision unit likely to be made of steel as opposed to plastic as moveable parts do not fare well in plastic.
It is highly unlikely you will find an efficient ceiling vent or register with a high life expectancy, in a hardware store.

Plasticisers migrate out of the plastic rendering it brittle with discoloration and looking for a reason to collapse and those with movable parts have a very early use by date.

It’s these little things, such as a ceiling registers or purge vents, that provide greater comfort levels without operational cost.

You may ask, how did we get by without them?…we didn’t. All houses built up to the sixties and seventies had wall vents and were not air tight, although fixed wall venting was disadvantageous during winter but great in summer months.

The presence of good ventilation systems allows doors to open and close easier, and by allowing efficient air displacement rooms are fresher with less odour retention and a lighter, less oppressive, feel about the area.

It’s the little things that are barely noticed that often make the biggest difference and the Purge Vent is one of them.

A good ventilation system in the home promotes well being and good health particularly in bedrooms during the sleep cycle.

There’s little point to exercising in the morning, jogging and the like, to increase your fresh air intake if you’re going to spend the eight hours before breathing spent toxic air.
