HOME & HEATING<br />

Ground moisture barrier<br />

under low sub-floor<br />

Now with the colder and wetter weather on<br />

its way, home owners are focusing on ways<br />

to make their homes comfortable, warm<br />

and healthy for their families throughout<br />

winter. Rising damp is an issue that affects<br />

many of our older properties which suffer<br />

from poor, or no, ground moisture barrier.<br />

In Canterbury especially, post-quake, many<br />

people have relocated to homes that suffer<br />

from rising damp which can be associated<br />

with health problems. Independent tests have<br />

shown that up to 40 litres of water can rise<br />

from the ground and enter a house every day,<br />

leading to mildew, mould, condensation and<br />

musty smells. Moulds can produce various<br />

allergic reactions and the frail, elderly and<br />

very young are especially vulnerable.<br />

Canterbury Foam Concrete Ltd is a<br />

locally owned and operated firm. The team<br />

understands the problems caused by rising<br />

damp and are there to help. They will come<br />

to your damp home and pump a lightweight,<br />

flowable foam concrete under your timber<br />

floored home.<br />

While insulation is important, it has been<br />

recognised that it is dampness that is the real<br />

villain in the house. The new Healthy Homes<br />

Standards introduced by the government<br />

effective from the 1st July 2019 now has<br />

a requirement to install ground moisture<br />

barriers, a key element in the armory to fight<br />

moisture in the home.<br />

Dr Larry Bellamy BE (hons) PhD in a<br />

report dated 1988: Foam Concrete Under<br />

Timber Floors: An Energy Analysis assessed<br />

the effects of placing Foam Concrete over<br />

damp soil and had this to say: Condensation<br />

on the underside of a timber floor can occur<br />

where the floor is suspended over damp<br />

ground and the inside air temperature falls<br />

close to the crawl space air temperature.<br />

Much energy is required to vaporize moisture<br />

that penetrates the structure. By avoiding<br />

underfloor condensation, foam concrete can<br />

reduce floor heat losses by up to 90%.<br />

• Canterbury Foam Concrete Ltd can in most<br />

cases, install a Ground Moisture Barrier<br />

under the suspended wooden floor of your<br />

home, even when there is no crawl space.<br />

The importance<br />

of air quality<br />

The quality of the air<br />

we breathe affects our<br />

health and ability to<br />

perform. We breathe in<br />

and out approximately<br />

20,000 litres of air every<br />

day. It is therefore very<br />

important to ensure<br />

good air quality indoors<br />

through adequate<br />

ventilation. Ventilation<br />

is the process of air<br />

exchange to provide the<br />

necessary air quality that<br />

meets the needs of the<br />

occupants for clean, fresh air. Low oxygen<br />

with high carbon dioxide causes stuffiness<br />

in the room and occupants can feel drowsy.<br />

Invisible harmful substances like a high<br />

content of dust and tobacco smoke are<br />

harmful and can cause various diseases.<br />

Even bad smells can cause discomfort or<br />

irritate the nervous system. In summer, it’s<br />

easy to open windows for cross ventilation,<br />

however as winter approaches, we start to<br />

shut up out houses to trap in the heat and<br />

as a result, air quality can decline.<br />

Ventilation includes both the exchange<br />

of air to the outside as well as circulation<br />

of air within the building. It is one of the<br />

most important factors for maintaining<br />

acceptable indoor air quality in buildings.<br />

Filtered air supply for summer and filtered<br />

and warmed air in winter creates a healthy<br />

environment in which to live and work.<br />

In cases with poor or insufficient air<br />

intake from outside, the oxygen content<br />

decreases, humidity and dustiness levels<br />

increase. If exhaust ventilation is not<br />

provided or it is not effective, polluted air,<br />

smells, humidity and harmful substances<br />

are not removed.<br />

To ensure the quality of your air, contact<br />

the experts. Smooth-Air Products can<br />

calculate the required air exchange for your<br />

building requirement. Smooth-Air offers<br />

a wide range of ventilation equipment,<br />

from air vents to ducting for fans, for both<br />

the commercial and domestic markets.<br />

They have an extensive range of fans and<br />

ventilation components in-store but they<br />

can also provide innovative solutions<br />

tailored to differing requirements.<br />
