Unveiling the Thermal Efficiency Champions: Awning and Tilt & Turn Windows

Updated: Jun 4

Introduction: When it comes to creating a cozy and energy-efficient home, the choice of windows can make a significant impact. At Spartan Double Glazing, we're all about providing you with the best solutions for energy efficiency, and today, we're diving into why Awning and Tilt & Turn windows reign supreme over sliding windows in the realm of thermal efficiency.

The Battle of the Windows: Awning, Tilt & Turn, and Sliding

Imagine a window that not only adds aesthetic charm to your home but also contributes to keeping it warm in winter and cool in summer. That's precisely what Awning and Tilt & Turn windows bring to the table. Unlike traditional sliding windows, these two contenders are designed to offer exceptional thermal efficiency, making them the go-to choices for those who seek an energy-efficient haven.

The Engineering Marvel: Awning Windows

Awning windows are akin to functional pieces of art. Hinged at the top and opening outward, they create an awning effect that lets fresh air in without compromising on insulation. The strategic design prevents rainwater from sneaking in while enabling optimal ventilation. The tight seal they provide when closed keeps the outdoor elements at bay, ensuring your indoor climate remains consistent.

Tilt & Turn: Innovation Redefined

Tilt & Turn windows are the epitome of modern window engineering. With a dual-action opening mechanism, they allow you to tilt the window for controlled ventilation or swing it wide open for easy cleaning and maximum airflow. This versatility doesn't just stop at convenience; it also enhances energy efficiency. When tightly closed, Tilt & Turn windows create an airtight seal that minimizes heat exchange, ultimately reducing energy consumption.

The Slide of Inefficiency: Sliding Windows

While sliding windows have their own charm, they often fall short in the thermal efficiency department. Their design, with overlapping panes that slide horizontally, can lead to gaps that compromise insulation. This can result in heat loss during winters and heat gain during summers, leading to higher energy bills and a less comfortable living environment.

The Numbers Don't Lie: Energy Savings

When you opt for Awning or Tilt & Turn windows from Spartan Double Glazing, you're investing in long-term energy savings. These windows are designed to meet stringent energy efficiency standards, ensuring that your home remains comfortable year-round without excessive reliance on heating or cooling systems. The insulation they provide acts as a barrier, keeping unwanted temperature fluctuations at bay and letting you enjoy a more sustainable lifestyle.


In the realm of thermal efficiency, Awning and Tilt & Turn windows emerge as the clear winners, leaving traditional sliding windows in the dust.
