Awning Window vs Casement Window: Pros, Cons, & Which to Choose

When it comes to selecting the perfect windows for your home or commercial building, the decision between an awning window and a casement window can be a tough one. Both types of windows have unique characteristics that suit different needs, preferences, and architectural styles. 

In this in-depth guide, we’ll explore the pros and cons of each window type, their functionality, cost, and more, to help you make an informed decision for your property.

Awning Window vs Casement Window: A Quick Comparison

Awning Window vs Casement Window: Which Is Better?

How Awning Windows Work

Awning windows are hinged at the top and open outward, providing a unique mechanism compared to standard windows. These windows are designed to let in air even during rain, thanks to their outward opening nature which allows the top to remain shielded from the elements.

How Casement Windows Work

Casement windows are hinged on one side, typically opening outward using a crank mechanism. These windows offer a wider opening than awning windows and are perfect for those who want to enjoy maximum ventilation and airflow.

Awning Window vs Casement Window: Materials

Both window types are available in a variety of materials, each with their own advantages.

View & Natural Light Intake

Both awning and casement windows are great at allowing natural light into your property. However, casement windows tend to offer a wider view due to their larger opening and more expansive design, making them ideal for living areas where natural light and views are important. 

On the other hand, awning windows, while they may not provide as wide of a view, are excellent for smaller spaces that require ventilation while still maintaining privacy.

Insulation & Energy Efficiency

Both types of windows can provide excellent insulation when installed properly. However, casement windows typically offer a better seal than awning windows due to their side hinges and locking mechanism, providing improved energy efficiency. 

For homeowners seeking top-notch insulation, casement windows may be the better option.

Glazing Options

Single glazing is less energy-efficient, while double and triple glazing offer better insulation, reducing heat loss and increasing energy savings.

Ventilation & Draughts

When it comes to ventilation, both window types perform well. Casement windows provide a larger opening for airflow, while awning windows allow for continuous ventilation even when it’s raining. 

However, due to their tight seals, casement windows tend to have fewer draughts and better insulation.

Security Features

Both window types come with built-in security features. Casement windows often feature a multi-point locking system, providing a secure seal. Awning windows, while secure, may not offer the same level of security as casement windows due to their opening mechanism, making it easier for burglars to access in some cases.

Maintenance & Longevity

In terms of maintenance, both window types are relatively easy to care for. However, casement windows require more upkeep due to their crank mechanism, which can wear over time. Awning windows have fewer moving parts and require less maintenance in general.

Costs & Installation

The price of new windows can vary depending on the material (uPVC, timber, aluminium) and glazing options chosen.

In general, awning windows are more affordable, especially when opting for uPVC. The cost of casement windows, particularly in timber or aluminium, can be more expensive.

Installation Requirements & Timeframe

The installation of both window types typically requires professional fitting to ensure proper sealing and function. Casement windows may take slightly longer to install due to the cranks and complex hardware.

FAQs

Are casement windows still popular?

Yes, casement windows remain very popular. Their hinged design allows for maximum ventilation and is highly energy-efficient, as they seal tightly when closed. 

Casement windows are especially common in modern homes due to their sleek appearance and practicality. They are often chosen for their ease of use, ability to open fully, and superior airflow.

Are awning windows energy efficient?

Awning windows are generally considered energy-efficient. When closed, they create a tight seal, which helps reduce air leakage. This feature is especially beneficial in preventing drafts and improving insulation. 

Additionally, because they open outward at an angle, they allow for natural ventilation while preventing rain from entering the home. If you choose high-quality, energy-efficient glass, awning windows can contribute to better energy savings.

Can awning windows be double glazed?

Yes, awning windows can be double glazed. In fact, double-glazed windows are often recommended for awning windows to improve insulation and soundproofing. 

Double glazing helps reduce heat loss during winter and keeps your home cooler in the summer, making your home more energy-efficient overall.
