Trends toward transparent buildings with minimal visible hardware push manufacturers to create products that are high-performing, durable, and visually pleasing. Quality is crucial, as poor fittings compromise both functionality and appearance.
Project location, type (residential, commercial, industrial), product finish, location of the door, budget, general climatic conditions, security level, access control requirements, occupancy, and local stock availability are important factors in the selection of hardware. By considering these criteria, architects and designers can select hardware that not only meets the functional requirements but also enhances the visual appeal and character of the building.
Can you discuss any recent trends in hardware design that cater to modern architectural aesthetics?
The hardware industry continues to evolve, and several key concepts are gaining traction in the industry. This model not only enhances functionality but also highlights the combination of aesthetics with modern architecture.
Current trends in hardware include:
- Finishes: The industry is moving away from standard finishes of Satin SS, black, satin brass, etc. The interior designers and developers are experimenting with bold finishes like gunmetal, dark umber, fused nickel bronze, brushed bronze, etc.
- Digital Door Locks: In the GCC market, door locks are gaining popularity because they incorporate digital technology to meet the growing demand for home automation and the demand for keyless entry systems. These locks offer superior security, including biometric authentication and remote access, making them an essential part of the modern smart home. The system has completely replaced the door hardware.
- Integrated Lock Levers: Integrated lock levers are revolutionising traditional door hardware by incorporating locking functions directly into the lever handle, eliminating the need for a separate escutcheon. These minimalist lever handles can also accommodate matching veneers and stones, seamlessly blending with the door finish and enhancing the overall aesthetic appeal.
- Pocket Sliding Fittings with Service Tracks: Pocket sliding fittings have historically been avoided due to high maintenance requirements and the potential need for wall modifications during servicing. However, the advent of dual-track technology has addressed these concerns. This system allows for the installation of a fixed track during construction, while an internal serviceable track can be easily removed for repairs or adjustments without disrupting the wall structure.
- Invisible Frames & Door Fittings: Invisible door fittings are designed to create a sleek, seamless appearance by minimising gaps between the door and frame to just 2-3mm. These doors are mounted with concealed hinges and door closers, ensuring smooth operation while maintaining a discreet profile. The use of metal frames and camouflaged designs allows these doors to blend seamlessly with wall finishes, achieving a modern, minimalist look.
In summary, the latest trends in architectural hardware reflect a shift towards integrating advanced technology, enhancing aesthetics, and improving functionality.
What are the latest sustainable practices being adopted by hardware manufacturers?
‘Longevity is sustainability’ – extended cycle testing ensures the product is fit for many years of operation & does not need replacement throughout the lifetime of the building. Accordingly, companies are designing hardware products with durability and recyclability in mind, facilitating easier disassembly and recycling at the end of the product’s life. This cradle-to-cradle approach helps reduce landfill waste and supports a circular economy.
Furthermore, companies are showing their commitment to sustainability by participating in carbon offset programs like planting trees and using renewable energy sources, such as solar or wind power, to reduce their environmental footprint further. Use of plastic is being avoided & recyclable packaging is being considered in the packaging of material. These efforts collectively contribute to a more sustainable hardware industry.
How does proper installation impact the performance and lifespan of hardware?
Proper installation ensures that the hardware is securely fitted and aligned, preventing issues such as misalignment, loosening, or undue stress on parts. For instance, in door hardware like hinges and locks, improper installation can lead to misalignment, causing the door to sag or not close properly, which can accelerate wear and necessitate early replacement.
Moreover, correct installation includes following manufacturer guidelines and using the appropriate tools and materials. This adherence to specifications ensures that the hardware can handle the expected loads and stresses, maintaining its structural integrity over time. In short, proper installation not only optimises the immediate functionality of hardware but also significantly contributes to its longevity and durability, protecting the investment and reducing long-term maintenance costs.
Annual inspections of fire-rated assemblies & exit doors should be conducted and enforced to ensure door openings are properly adjusted and maintained for usability and safety.
How has technology influenced the design and functionality of modern architectural hardware?
- Smart Technology: Integration of keyless entry systems, automated doors, and sensor-activated hardware for improved security and convenience.
- Energy Efficiency: Development of low-energy-consuming door closers and window hardware that optimise natural lighting and ventilation. Smart digital locks are also being furnished with rechargeable lithium-ion batteries.
- 3D Modelling: The use of 3D software helps factories to experiment with designs more creatively. Even the use of 3D printers facilitates to manufacture the visualised designs in ABS plastic through rapid prototyping with stereolithography machines. This is the first step we do for custom handles so that actual geometry & dimensions can be reviewed.
Overall, these technological innovations provide functional, durable, and aesthetically pleasing solutions for architectural hardware.
Can you discuss the integration of smart technology into architectural hardware and its benefits?
The integration of smart technology into architectural hardware is transforming the way we interact with buildings and spaces. Smart architectural hardware, such as automated door locks, touchless access systems, and intelligent lighting, enhances convenience, security, and energy efficiency. These innovations allow for seamless control and monitoring via smartphones or other devices, making building management more accessible and efficient.
One of the key benefits of smart technology in architectural hardware is enhanced security. Features like biometric access, remote monitoring, and automated locking systems ensure higher levels of protection against unauthorised access.
What are the key considerations for ensuring architectural hardware meets safety and regulatory standards?
Ensuring architectural hardware meets safety and regulatory standards is crucial for the integrity and functionality of a building. Doors act as barriers to the spread of smoke and fire. Ironmongery on doors is an important component to ensure the effectiveness of the operation of the barrier. Self-closing mechanisms, positive latching intumescent packs behind mechanical items on timber doors to limit the spread of fire, and seals to prevent the spread of smoke. There are third-party certification bodies that test the products on doors and guidelines issued by international bodies to ensure conformity to the guidelines.
In the selection of hardware, safety and security are interchangeable which creates some confusion in the selection process. It is important to note that security is of utmost importance and many times a balance must be made between safety and security.
What are the current challenges faced by the architectural hardware industry?
Construction methods have been constantly evolving and with that, all trades are also expected to keep pace. Safety, security, climate change, sustainability, price, and finishes are given a lot of credence along with aesthetics and traditional forms of operating doors and windows.
The hardware industry has been keeping abreast of all these challenges with constant improvements being made. Hardware specification for doors and windows is now a very specialised subject and we have multiple educational qualifications to train aspiring professionals on the nuances of specification. GAI and AHC for European and American norms respectively have more than three years of courses to get a professional certification that helps them aid consultants and contractors on the specification, installation, and compliance to various statutes that exist.
