Ventilation and Insulation is a Cool Combination

Good ventilation is the panacea for a hot, stuffy and uncomfortable home especially during summer weather.  Without it, the inside of a home becomes unbearable. Installing insulation can help but it can also act as an agent for blocking air and moisture from escaping, giving rise for fungi growth. But insulation combined with an effective ventilation system is the perfect solution for a stuffy house. Another question arises: What type of ventilation should you have installed in your home to complement your insulating efforts?

Types of ventilating systems available


  • The ‘whirlybird’ vent

This cleverly designed ventilating system is both very simple and effective. Its dynamic properties consist of a vent with turning lightweight blades that rotate from the flow of air coursing through the vent. As they rotate the blades whirl warm air from the house and forces  it outside. For maximum effect, many vents need to be installed to facilitate a constant cleansing of air within the home.

  • Solar powered vents

These type of vents are highly also efficient and self-energizing. Their dynamic feature is amazingly simple consisting of a solar panel attached to an exhaust van that draws unclean air from inside the home and expels it outside. Unlike the whirly bird vent which need to be installed in the higher parts of the house, these solar powered vents can be installed anywhere in the house. The only drawback is that the system lacks storage capability, meaning that it can only work during the day but not during the night.


  • Electrically powered vents
    Manufactures view this system as perhaps being the most efficient of all the systems available, the main reason being that the system is versatile and offers the best solution for achieving a constant flow of cool air inside your home. It is well ahead of the other 2 systems mentioned here because it operates non-stop unless you or a power outage turn it off. Another plus for this ventilation system is that the benefits gained by far outweigh the costs of installing, operating and maintaining the system


Which system should you choose?

Before you go ahead and make a dare in choosing a ventilating system, you should first ensure that your house is suitably insulated against radiated heat from the roof and walls. Choosing the most appropriate ventilating system is more complex because no single system can fit the different kinds of prevailing conditions. However, you may prefer whirlybirds because all you need to do is install the right numbers only once and they do the rest. It would make sense to opt for a ventilation system powered by sunlight if you live in an area with a lot of sunlight all year round. On the other hand, you may prefer an electrical ventilation system because it can operate continuously day and night. The choice is entirely yours to make.
