For this reason, indoor comfort in hot climates is largely dictated by the effectiveness of a building’s passive heat gain control capabilities. One such question we are often asked at GREFET is whether aluminium system windows do actually keep indoor temperatures down?

The short answer: purely aluminium windows do not “cool” a space, nevertheless smartly crafted system servicing home windows can significantly boost warm reduction and furthermore minimize in-door temperatures.

Understanding Heat Gain Through Windows

The majority of hot air comes in through windows. Poorly designed systems allow:

Direct solar radiation to enter
Hot air infiltration through gaps
Heat transfer through frames and glass

That is where engineered systems come into play.

Finding Indoor Heat with System Aluminium Windows

GREFET develops aluminium window systems that regulate heat in multi-parameters.

1. High-Performance Glass Integration

The single biggest one is the glass.

Double glazing reduces heat transfer
Low-E coatings reflect solar radiation
Tinted or reflective glass reduces the bright sunlight and heat

2. Thermal Break Technology

Standard aluminium conducts heat. This is why system windows include a thermal break.

Inner and outer frame are insulated from each other
Reduces heat conduction significantly
Improves indoor temperature stability

3. Air-Tight Sealing Systems

It comes from the spaces around windows letting in hot air.

Our systems use:

Multi-layer gaskets
Precision-engineered sealing
Controlled air infiltration

This prevents hot outdoor air from entering in and cool indoor air from escaping.

4. Smart Design and Orientation

The placement and size of the window also play a role in its performance.

Better glazing systems are needed for larger openings

What This Means in Real World Scenarios

You should notice the difference when you install system aluminium windows with high performance.

Less heat accumulation indoor in peak summers
Lower dependency on air conditioning
More consistent indoor temperatures
Improved overall comfort

This difference – is most prominent in cities suffering from extreme heat.

Aluminium vs Traditional Window Materials

Less waste compared to wood, or aluminium’s of lower complexity

More well-sealed than other types of system aluminium windows
They are not prone to warping or thermal expansion
They maintain performance over time
They support advanced glass configurations

And this actually is meant for long term thermal efficiency, not temporary relief.

GREFET’s Approach to Thermal Performance

At GREFET we go through not one angle. We design complete systems where:

Profiles glass and hardware work together
All the factors have a role of reducing heat.
Performance remains consistent across projects

The system-oriented view assures that windows are contributing to indoor comfort.
