This comprehensive guide explores various types of windows, their features, benefits, and ideal applications, with a focus on Dekko’s extensive product range of styles.

Understanding the nuances of each window type will allow you to provide your customers with the best possible solutions for their homes and businesses.

What Factors Should You Consider When Choosing the Best Windows for a Project?

When selecting new windows, it’s important to consider several factors, including energy efficiency, aesthetics, and functionality. The style of window should complement the building’s architecture while providing excellent ventilation and natural light.

Additionally, the choice of materials, glazing options, and window placement are all important considerations for ensuring optimal performance and customer satisfaction.

Exploring the Most Common Types of Windows

Let’s delve into some of the most common types of windows available from Dekko, examining their unique characteristics and advantages:

Casement Windows: Versatile and Practical

The casement window is one of the most popular types of windows, known for its versatility and clean lines. Hinged on one side, it swings outward like a door, providing unobstructed views and allowing ample amounts of fresh air into the property. These windows are ideal for both modern homes and traditional properties, thanks to their timeless design.

Dekko’s standard casement windows are available in a variety of high-quality materials, including durable uPVC frames and sleek aluminium frames, ensuring long-lasting performance. For customers seeking a contemporary look, Dekko’s flush casement window offers a seamless finish that sits flush within the frame. These windows are also available in a wide range of finishes and a variety of colours, making them adaptable to any architectural style.

Benefits:

• Easy operation with simple handles.
• Provides excellent ventilation.
• Suitable for both small and larger window openings.
• High levels of thermal performance with options such as double glazing.

Ideal Applications:

Casement windows are perfect for residential properties that require energy-efficient solutions with an emphasis on practicality. They are particularly suited to areas where unobstructed views or maximum airflow are desired.

Sash Windows: Classic Elegance for Period Properties

For projects involving period properties or homes with traditional architecture, few options rival the charm and elegance of the classic sash window. These windows feature two sashes that slide vertically within the frame – one at the top and one at the bottom. Their design is synonymous with heritage buildings but can also be adapted for more contemporary settings.

Dekko offers both traditional timber-effect sash designs as well as modern uPVC alternatives that combine classic aesthetics with cutting-edge performance features like improved security and thermal insulation. For trade installers working on renovations or restorations, these windows provide an authentic look while meeting modern building standards.

Benefits:

• Timeless appeal that complements traditional properties.
• Allows flexible ventilation by opening either the top or bottom sash.
• Available in modern materials like uPVC for increased durability.
• Suitable for double glazing to improve energy efficiency.

Ideal Applications:

Sash windows are ideal for restoring historical buildings or adding character to new builds designed in a traditional style. They’re also popular in upper-floor installations where safety is paramount.

Bay Windows: Architectural Beauty with Extra Space

A favourite feature in many homes, bay windows extend outward from the building’s structure, creating a sense of openness and adding valuable extra space to interiors. These windows typically consist of three or more panels arranged at angles to form either a polygonal or curved shape (known as bow windows). They are not only functional but also serve as stunning architectural focal points that bring in abundant amounts of natural light.

Dekko’s customisable bay window options allow trade installers to tailor designs to suit specific project requirements. Whether working on a renovation or designing for a new build, these windows can be manufactured in various sizes and styles to match different types of properties.

Benefits:

• Maximises natural light intake.
• Adds extra interior space – ideal for seating areas or storage.
• Creates panoramic views.
• Improves kerb appeal with striking architectural detail.

Ideal Applications:

Bay windows are perfect for living rooms, kitchens, or other spaces where homeowners want to enjoy expansive views while creating a cosy nook inside. They work well in both modern designs and traditional homes.

Tilt-and-Turn Windows: Modern Functionality Meets Style

For trade installers seeking versatile solutions that combine practicality with sleek aesthetics, tilt-and-turn windows are an excellent choice. These innovative designs allow homeowners to tilt the window inward at an angle for controlled ventilation or fully open it inward like a door – making cleaning easy even on upper floors.

Dekko’s tilt-and-turn options are available in durable materials such as uPVC and aluminium frames, ensuring superior performance in terms of security and thermal efficiency. Their adaptability makes them suitable for both residential and commercial installations.

Benefits:

• Dual functionality: tilt mode for ventilation; turn mode for access.
• Easy cleaning from inside – ideal for upper floors.
• Secure locking mechanisms improve safety.
• Modern styles complement contemporary homes.

Ideal Applications:

Tilt-and-turn windows are ideal for urban settings where space is limited but functionality is essential. They’re particularly suited to apartments or properties with upper-floor installations requiring easy maintenance access.

Other Window Options from Dekko

In addition to these core categories, Dekko offers specialised solutions such as:

Roof Windows and Roof Lanterns

Transform dark attic spaces or extensions into bright living areas with Dekko’s range of roof products. Both roof lanterns and roof windows maximise natural light penetration while maintaining excellent thermal performance. These options are particularly useful in loft conversions or modern open-plan designs where light flow is critical.

Choosing Materials and Glazing: An Important Consideration

The choice of materials plays a vital role in determining the durability, appearance, and energy efficiency of any window installation. Dekko’s offerings include:

• uPVC Frames: Cost-effective yet durable; perfect for residential projects prioritising affordability without compromising quality.
• Aluminium Frames: Sleek and strong; ideal for modern designs requiring slim profiles.
• Timber-effect finishes: Combine classic aesthetics with low-maintenance benefits.

Additionally, glazing options such as double glazing can significantly improve energy ratings while reducing noise pollution – a key selling point for trade installers working on urban developments.
