Aluminium windows and doors are essentially energy efficient, which is one of the many characteristics of aluminium that makes it a better metal for the construction of doors and windows.

The cost of power consumption is increasing with each passing day, and along with that, mankind is growing more conscious of the environmental impacts of their lives and living. However, opting for the aluminium doors and windows can result in dissolving both of these problems. If you are living in Perth, near Western Australia, or in and around the land down under, then Com-Al Windows would certainly help you get the best energy-efficient commercial aluminium windows and doors for your office or commercial buildings that are tested to meet the Australian standards.

Why is Energy Efficiency Important When it Comes to Doors

and windows?

Energy efficiency is really important today both for residential and commercial buildings and complexes. Much of the energy is lost today from our homes and offices, and this is mainly due to the installation of inefficient doors and windows. While in the summer, when we want to keep our indoors cooler, the hot air pouring in from drafty/inefficient windows and doors, makes the air conditioner work harder than usual. On the other hand, during winters, when we want to keep the inside of our rooms warm and cozy, we often find cool air that comes in, which makes things challenging indeed for ourselves and our machines. All of these can come to an end if we aim for energy efficiency in doors and windows.

Being energy-efficient would mean:

• Cutting down on your bills
• Getting the optimum temperature and humidity that you want indoors
• Saving energy by minimizing additional heating/cooling
• Adding more life to your heaters/coolers
• Lower maintenance costs
• Getting adequate comfort
• Enhanced property value

The fundamental difference between the energy-efficient doors and windows, and those that are not energy-efficient is that the former kinds of doors and windows allow the inside temperature to be different from the temperature outside. This happens due to their excellent thermal reflection properties. Using energy-efficient commercial doors and windows for your office/buildings will help you maintain both the temperature and humidity at ideal levels indoors regardless of their levels outside.

Aluminium as an Energy-Efficient Material for Commercial

Windows and Doors!

Aluminium is largely chosen today as the primary material for the construction of both residential and commercial windows and doors. This is basically due to the high energy efficiency ratings of aluminium, and the broad spectrum of customisation that it offers its users.

Yes, along with the high efficiency, strength, durability, and aesthetic appeal that it is praised for, aluminium frames can also be trimmed down by the installers to a large extent, thereby helping the glass to take the centre stage. Glass, which in itself, is a bad conductor of heat, allows minimum heat to pass in/out, which helps keep the room temperatures and humidity at desired levels of efficiency.

The metal wasn’t really energy-efficient when it was first discovered as an alternative for the doors and windows. However, with years of development, double glazing technology emerged, which helped aluminium significantly to claim its place as one of the most energy-efficient materials for doors and windows today. Fast forward to now, when we have double glazing, which is combined with the thermal break technology and low emissivity glass units that are fitted to the aluminium doors and windows, aluminium has earned an imposing presence in the doors and windows segment.

If you are also wondering about choosing energy-efficient doors and windows for your commercial complex, you just need to reach out to Com-Al Windows, who would help you get the best of what you want.

Nonetheless, aluminium is an unbeatable material for the doors and windows now, but do you know that the energy efficiency can vary from room to room. Yes, energy efficiency depends on numerous factors, and the energy efficiency ratings can also depend on a list of reasons.

What is an Energy Efficiency Rating?

As energy efficiency is a crucial factor that is greatly pursued by the owners of homes and offices today, efficiency has luckily turned out to be a measurable value that can be measured by energy performance ratings. These ratings for energy efficiency are issued by government bodies and determine the efficiency of doors and windows too, which further helps the users choose the most efficient residential and commercial aluminium windows and doors. The energy efficiency ratings of doors and windows also greatly differ due to numerous factors that we will check below.

Main Factors that Affect the Energy Efficiency Ratings of Windows and Doors!

Though performance scores are almost meaningless for the house owners or the owners of commercial buildings and offices, knowing the energy efficiency ratings and the factors on which they depend are important indeed, and will ultimately help them maintain efficiency indoors.

Here are some of the prominent kinds of ratings and how they affect the commercial windows and doors and their residential counterparts.

• U Factor Ratings

The U factor ratings range between 0.15-0.39, where the low end of the rating can only be achieved while using a triple-glazed window. The best of these ratings fall between 0.17-0.30 in the summers. Now to define, a standard clear window with a single pane of glass has its U factor rating of around 1.09. Here, you need to look for the lowest U-factor ratings while choosing commercial aluminium doors and windows.

• Solar Heat Gain Coefficient Ratings

The solar heat gain coefficient ratings largely depend on the direction of the walls of a room and the climate to which they are exposed. To make this simpler, high solar heat gain is good in cold climates for the south-facing walls, whereas, in hot climates, solar heat gain values of 0.25 are good. Much like the U-factor ratings, the solar heat gain coefficient ratings should also be lower to be more efficient. A standard piece of glass’ solar heat gain coefficient rating is around 0.81.

• Air Leakage Ratings

By the name itself, it can be identified that the air leakage ratings somewhat define the air leakage from the rooms. These ratings range from 0.1-0.3 where the lower the air leakage rating, the better it is for the users.

• Visible Transmittance Ratings

Visible transmittance influences the light transmitted to the rooms from outside. These ratings stay between 0-1, where the higher the visible transmittance rating, the more the light that is passed indoors. Here, for commercial aluminium doors and windows, you ideally need to seek lower ratings of visible transmittance where work is done on the laptops and computer screens to cut down on the glare received. However, on the other hand, for the doors and windows that are installed in the other areas, where you either have plants or you need more natural light like the entrance, you need to go for higher transmittance ratings.

Keeping all these ratings in mind, and figuring out the best commercial aluminium doors and windows might sound tough, but it will seem far from challenging with Com-Al Windows within your reach. Established back in 1970, Com-Al Windows brings in years of experience and expertise in the doors and windows contracting industry and would help in designing, manufacturing, and installing the kind of aluminium doors and windows that you have always wanted, complete with commercial cyclonic glass and curtain walling systems.
