ST, HKS, HST, PAS and Bi-fold patio doors - Differences and which you should choose?

Patio doors are an essential feature in any home, serving both a functional and aesthetic purpose by connecting your indoor living space to your garden or patio. They can create a sense of openness, increase natural light, and even improve the flow of your home. Choosing the right type of patio door depends on several factors, such as the available space, the style of your home, your energy efficiency requirements, and how you plan to use the door. Options like ST, HKS, HST, PAS, and bi-fold doors each offers different benefits in terms of operation, insulation, security, and visual appeal. With so many choices available, understanding the key differences between these types of doors is essential for making the best decision for your home. Whether you're looking for something simple and practical or a more sophisticated design, the right patio doors can greatly enhance the overall look and functionality of your living space.

ST Patio Doors - A simple and classic option

ST patio doors, often referred to as standard sliding doors, are a popular and practical choice for homeowners who value simplicity and functionality. These doors consist of two large glass panels, one of which is fixed while the other slides horizontally to open and close. The sliding mechanism is easy to operate and ideal for homes with limited space, as the doors don't require room to swing open, unlike hinged doors. This makes ST doors a great option for smaller homes, flats, or areas where space efficiency is crucial. Beyond their practicality, ST patio doors allow for expansive views of the outdoors and let in an abundance of natural light, creating a brighter and more open-feeling living space. While they may not offer the same level of flexibility as more advanced options, ST sliding doors are a cost-effective solution for homeowners seeking a clean, modern design with a focus on practicality. Many newer models also feature enhanced thermal insulation, making them energy-efficient and environmentally friendly.

HKS Patio Doors - Tilt-and-slide functionality

HKS patio doors bring an innovative twist to the traditional sliding door design, offering a tilt-and-slide mechanism that provides added versatility. Unlike standard sliding doors, HKS doors allow you to tilt the door inwards at the top, providing ventilation without needing to fully open the door. This feature is especially beneficial for homeowners looking to improve airflow while maintaining security, as the door remains securely locked in the tilted position. The tilt function also allows for better control of ventilation in various weather conditions, making HKS doors perfect for homes in climates with variable temperatures. In addition to their ventilation benefits, these doors still offer the smooth sliding operation of standard sliding doors, making them easy to use and highly functional. HKS doors are available in a range of materials and finishes, allowing you to choose a style that complements the architecture of your home while enjoying the added benefits of modern functionality. Their unique combination of flexibility, security, and ease of use makes HKS patio doors an appealing choice for many homeowners.

HST Patio Doors - Lift-and-slide for larger spaces

HST patio doors, also known as lift-and-slide doors, are designed for homes with large openings and wide vistas, making them perfect for properties that want to blur the line between indoor and outdoor living. These doors feature a specialised lift mechanism that raises the door off the track when in use, allowing for smooth and effortless sliding even with larger, heavier glass panels. This lift-and-slide functionality makes HST doors ideal for expansive doorways, where traditional sliding doors might struggle with heavier loads. Not only do HST doors offer superior ease of operation, but they also excel in thermal insulation, thanks to their thicker profiles and well-sealed construction. This makes them a great choice for homes in colder climates, as they help maintain a stable indoor temperature by reducing heat loss. The large glass panels used in HST doors also provide uninterrupted views of the outdoors, making them an architectural feature that enhances both the interior and exterior aesthetic of your home. For homeowners looking to combine elegance, functionality, and energy efficiency, HST doors offer a premium option.

PAS Patio Doors - Secure and well-ventilated

PAS patio doors, short for Parallel Action Sliding doors, are designed with both security and ventilation in mind, offering a unique mechanism that sets them apart from traditional sliding doors. These doors operate by sliding parallel to the wall, similar to standard sliding doors, but they also have the added functionality of a slight outward tilt, allowing for secure ventilation. This means you can leave the door slightly open to allow fresh air in without sacrificing security, as the door remains firmly in place even in the ventilation position. PAS doors are an excellent choice for homeowners who live in high-traffic areas or who prioritise security while still wanting to enjoy fresh air. The innovative parallel action also provides smooth and reliable operation, with minimal effort required to open or close the door. In addition to their functional benefits, PAS doors come in a variety of modern and stylish designs, making them a visually appealing option for contemporary homes. The large glass panels typical of PAS doors ensure that plenty of natural light enters your home, enhancing both the aesthetics and comfort of your living space.

Bi-Fold Patio Doors - Maximising flexibility and space

Bi-fold doors are perhaps the most flexible and space-maximising option available when it comes to patio doors, making them increasingly popular in modern home design. Unlike sliding doors, which only allow a portion of the door to open, bi-fold doors consist of multiple panels that fold back against each other, creating a wide, uninterrupted opening. This feature makes bi-fold doors ideal for homeowners who want to create a seamless transition between their indoor and outdoor spaces, making them perfect for entertaining or simply enjoying the garden. Bi-fold doors are especially well-suited for larger openings, but they can also be customised for smaller spaces, offering versatility in terms of size and configuration. Available in a wide range of materials such as aluminium, timber, and uPVC, bi-fold doors can be tailored to match the style and architectural needs of any home. They also offer excellent energy efficiency, with many models featuring advanced insulation properties to help maintain indoor temperature and reduce energy costs. Bi-fold doors are a stylish, functional, and modern choice for homeowners looking to enhance their living space by maximising natural light and providing easy access to the outdoors.
