nelson lebo: positive pressure ventilation will suck up your cash

OOPS!
What is the difference between a word.
In last week\'s column, when I mentioned the positive pressure ventilation system, I accidentally used \"our home\" when I should use \"one home \".
In the context of explaining that the dehumidifier is sometimes valuable, I wrote: \"It is there if we need it, but like the positive pressure ventilation system installed in the roof cavity, it will only remove the moisture that already exists in our home.
\"Please note that we do not have a positive pressure ventilation system and I will not consider the installation either.
They are expensive, and studies have shown that they reduce the temperature at home by two to three degrees.
Therefore, they are certainly not suitable for the ecological environment.
Frugal approach to lowcost/high-
Performance housing.
You may not be familiar with the word \"positive pressure\", but the brand name will certainly be.
The two largest companies are known for their initials, and moreor-
New Zealand has fewer household names.
Small companies tend to put a fashionable word in front of the word \"vent\" to brand themselves.
The fictional example is platinum. Vent, Uber-Vent, or Sweet-As-Vent.
As far as I know, the positive pressure ventilation system makes the home cold in two ways.
The first and most obvious method is that they deliver cold dry air from the roof cavity to the living space.
This tends to make a home dryer at the expense of warmth.
On the other hand, there needs to be a more comprehensive understanding of the function of the family, so we can expect complaints from enthusiastic writers who neither read for understanding nor tend to believe in scientific research to the Chronicle.
As I have written dozens of times in the last 40 months, limiting the airflow around the curtains is critical to the curtain\'s function as a window insulation.
Close the top of the curtain track with pelmet or similar strategies to ensure that the curtain touches the floor is the most important factor in the performance of the curtain.
However, at least one positive pressure ventilation company specifically recommends that buyers of their systems open the top and bottom of the curtains to allow adequate airflow.
This suggestion makes the home colder.
In addition to the unexpected wording errors, last week\'s column was all about preventing moisture before it piled up at home.
After dehumidifier and positive pressure ventilation-the-The facts are close.
They treat symptoms of unhealthy families.
But like modern medicine, treating causes is better and more cost-effective than treating symptoms.
With this in mind, here is a question for readers of Chronicles.
\"What is the best covering for bathroom windows?
There is a large window on the bathroom vanity.
I like to keep the bathroom door open and airy, but the cold came in through the window all winter.
Be cautious about installing hot curtains in damp-prone rooms.
I have a shower dome which is perfect for reducing the steam generated by the shower.
We would like to thank you for your suggestion. \" -
Liz Solly thanks Liz for not being able to have curtains or roman blind in any bathroom for no reason.
As you pointed out, the key is to manage moisture.
The shower dome is great. Similar products are called steam stop.
But in both cases, with 10-
The minute delay timer may be an additional measure to ensure that the bathroom does not suffer from high humidity for a long time.
Any type of curtain should be done from this point of view, although I will avoid using cotton.
Again, I got this feedback from another reader: \"As we put polyethylene under my house, my home became warmer and drier.
In the kitchen, my wood floor often had large wet patches, very bad, I used to think the kids spilled something without telling me!
Since polyethylene went down, there was no sign of rising humidity. . .
My home feels healthier, drier and warmer, and my only regret is that I hope to do this a few years ago.
Recommend thoroughly.
Thanks Nelson. \" -
