A standard ventilation louvre will provide the maximum airflow required with minimal rain defence. These louvres tend to be preferred for projects where economy is the primary consideration, high free area is important and occasional water penetration will not cause significant problems.
What are the vents on the wall called?
Perhaps your vents are located on side walls or even on the floor. Depending on your setup, those are called registers or grilles. Registers and grilles help regulate the air flow to and from your HVAC unit. They are available in wood, plastic and various metals in a wide assortment of styles.
What are trickle vents for?
Trickle vents allow for a small amount of ventilation even when the window or door is closed. These vents are designed to help prevent or minimise problems associated with poor ventilation, such as condensation.
How do louvres work?
A louver is a ventilation product that allows air to pass through it while keeping out unwanted elements such as water, dirt, and debris. A number of fixed or operable blades mounted in a frame can provide this functionality.
What is a louvre system?
Louvre System
Louvre systems generally provide the passage of air to and from HVAC and other building systems, while protecting these openings against rain. Louvre screens are also used to conceal HVAC and other heavy equipment from view. In many cases, these systems are used purely for aesthetic effect.
Is it necessary to have air vents in walls?
Moisture Control
Static vents, positioned throughout older homes, controlled moisture. In some older homes, wall air vents helped remove moisture build-up between exterior and interior walls. This prevented mold from growing prior to the invention of sealants.
What are the different vents in my house?
There are three types of venting in your home: venting for supply air, return air and exhaust air. The effectiveness of these venting systems is facilitated by a combination of heating and air system materials, duct sizes, duct sealant and insulation.
What is the difference between a register and a vent?
WHAT IS THE DIFFERENCE BETWEEN AN AIR VENT COVER AND A REGISTER? An air register has the capability of adjusting the air flow by opening and closing a damper or flaps, usually found at the bottom of the air register. An air vent cover, simply covers the duct without the added feature of adjusting air flow.
Do trickle vents let in cold?

Should trickle vents be left open in winter?
People feel the draught and close the vent or think the room loses its heat. The purpose of trickle ventilators is providing a consistent flow of fresh air. Any cooling of the internal temperature in winter from a trickle vent is marginal. Keep your trickle vents open.
Is it OK to cover air vents?
You could mess with the air flow.
Just because you cover the vent, it doesn’t mean your HVAC system knows that. It will keep pushing air to those vents, and if they’re closed, you could cause a buildup of air pressure and insufficient airflow which could damage your system.
Should you close air vents in winter?
Air vents should be open to prevent damage
Increased air pressure can create cracks and holes in the ductwork. It can also cause your furnace’s heat exchanger to crack. Leave all air vents open to prevent extensive damage to your home’s heating system this winter.
Why is cold air coming out of my vents when the heat is on?

Are louvre windows airtight?
Altair Louvre Windows provide tight sealing due to: The living hinge design that resists water and air penetration between the clips and the channels. An over centre locking mechanism which applies strong locking pressure to blades when fully closed.
What is louver HVAC?
The Louver is a kind of a shutter or blind that comes with horizontal slats that are angled to allow space for light and air but restrict rain and direct sunlight whereas dampers control the airflow. In HVAC systems, dampers and louvers are used to regulate the flow of air.
Are louvers safe?
Louver or jalousie windows: Louver windows are especially vulnerable to intruders because the glass panes can be easily lifted out of their brackets from the outside. A simple way to increase the security of this type of window is to epoxy the panes to the brackets.
