Comparing Breezway Louvres with Other Aluminium Window Types
When mentally putting together their dream home after watching their favourite architecture or home renovation TV show, few people‘s thoughts about windows would extend much beyond wanting to frame views, or perhaps wanting to maximise natural light. Most people are unaware of the various advantages and disadvantages associated with the various window types.
Whilst some things are common to all window types, like keeping rain out and letting light in, the variety of window designs commonly used in Asia have a number of differences in the benefits that they will bring to your building.read more
Louvre Windows in Schools Can Improve Your Child’s Learning!
We all want the best for our children. We want them to do well in their studies, remain in good health, be friendly and have good manners. While I haven’t seen any scientific studies recently about how to improve their manners or be more friendly, there are many scientific studies showing that it is possible to improve their performance at school and reduce the frequency that they get sick by simply opening up windows to let in more fresh air.
Studies Showing Improved Learning Outcomes
A study in 2006 showed that children in classrooms with higher outdoor air ventilation rates tend to achieve higher scores on standardised tests in math and reading than children in poorly ventilated classrooms.
Controlled studies published in 1999 and 2000 showed that children perform school work with greater speed as ventilation rates increase. The performance of adults, including teachers and school staff, were also shown to improve with higher ventilation rates.read more
Automated Windows are best for High Level Natural Ventilation
The fact that air rises as it heats up has been used for centuries as a way to draw fresh, cooler air into a building. This is one of the prime reasons that double height voids and windows positioned close to the ceiling are common features of naturally comfortable homes.
Our Altair Louvre Windows are well suited to these applications for three reasons:
1. They remain fully functional even when using short and wide window shapes,
2. They maximise ventilation, and
3. They are one of the few window types which can be operated when out of reach.
Around 1 in 10 of the Altair Louvre Windows that we manufacture and sell have Ring Handles which are specifically designed for clerestory windows which will be out of reach and will be opened and closed using a Map Rod. Honestly, this frustrates me a bit. Not because I think that Ring Handles are bad, but simply because there are five really good reasons to upgrade these windows to automated Powerlouvre Windows.read more
The Energy Efficiency Benefits of Woven Mesh Screens on Louvres
“Can your louvre windows be screened?” is one of the most common questions we are asked. Altair Louvre Windows sure can be screened! They can be screened with fibreglass mesh to keep the insects out, or woven metal mesh to keep intruders out.
Most people don’t realise though that mesh screens offer more benefits than protection from insects and intruders. Specifically they offer some great energy efficiency benefits in the form of shading and thermal insulation.read more
Breezway Louvres Breathe New Life into SMK Subang Jaya
Breezway’s care for the community and our deep commitment to corporate social responsibility (CSR), was demonstrated in our sponsorship of Breezway Louvre Windows for Sekolah Menengah Kebangsaan Subang Jaya in Selangor. Sekolah Menengah Kebangsaan Subang Jaya, a school that is more than 40 years old, was in dire need of new windows as the existing louvres were rusty and in bad condition.
As part of its CSR efforts, Breezway undertook the refurbishment of the classroom with new Breezway Louvres and glass, in collaboration with Hargrave Corporation Sdn Bhd, who provided the labor for installation.read more
Ventilation Through Windows with Restricted Openings – Buyer Beware
The amount of ventilation through an Altair Louvre Window with its openings restricted is relatively unaffected, but for many window types a restricted opening device will severely reduce the ventilation through the window.
The picture displayed in this article is of a home spotted recently in subtropical Queensland, Australia where it appears that the chain winder of the window has been detached and a piece of timber is being used to hold the window open, most likely in an attempt to get some fresh air into the room.read more
Light and Shadow when using Altair Louvre Windows
With almost the entire eastern façade of the Breezway Head Office (in Australia) made up of a wall of Altair Louvre Windows there are two characteristics of our building that most visitors comment on….1) How pleasant it is to feel the breeze and 2) How much natural light streams into our building.
There’s another aspect that I really enjoy which few visitors get to see because it only happens first thing in the morning when the sun is low in the sky – and that is the light patterns caused by the angled, open blades.
Our Altair Louvre Windows have green tinted glass blades to reduce the amount of heat entering the building in the form of sunlight. The sunlight passing through the tinted blades and the sunlight passing between the tinted blades forms geometric patterns on the walls and floors.read more
Comparing the energy efficiency of ‘Esky’ buildings to passively designed buildings.
Years ago I attended a week long training course in the conference centre of a large hotel right on the beachfront. The food was pretty good but the conference room felt a bit like a dungeon! There were no windows at all and one of the presenters had this cruel theory that making the air conditioning extra cold would ensure that no-one fell asleep during the after-lunch sessions.
A few years later I attended another conference at a different venue that was also only 100m from the ocean. In contrast, this venue had windows looking out to the ocean and we could enjoy the fresh ocean breezes.read more
Enjoy the day while reducing your electricity bill – open your office windows!
It’s a beautiful winter’s day in Brisbane today: blue skies, 23C with a breeze blowing from the west. Unlike most other office workers around the city today, I can actually feel the breeze. It’s not because I’m working outside though, it’s because the air conditioning is off and the office windows are open. No, I don’t work in a small home office, the Breezway head office here in the suburb of Coorparoo has a floor area of 660m2 spread over 3 floors.read more
“For every complex problem there is an answer that is clear, simple, and wrong.” - H. L. Mencken (1880-1956) The energy efficiency of a building is influenced by many different design aspects. Orientation, insulation, ventilation, shading, sealing and building size...read more
