“Use Right Hardware for the Right Applications”
By: Amit Malhotra
Important Hardware for Doors and Windows
Apart from the standard model of single-point locking with Cockspur Handles, PVC-U doors and windows are characterised by the ability to be locked at multiple points for added safety and better sealing. This is done by Espagnolettes with multiple locking points, strikers and operated by an appropriate handle, both in casement as well as sliding doors and windows.
Friction hinges for windows and 3D, 2D and Butt hinges for doors provide the necessary hinge action in casement doors and windows, while rollers, both single and double nylon or steel-wheeled, swing or adjustable, provide the movement to sliding doors and windows.
However, of late, a plethora of specialised hardware for tilt & turn, slide & fold, lift & slide, tilt & slide, slide & pivot and vertical windows and doors have evolved and are increasingly being brought into use.
Need for choosing the right kind of hardware for windows and doors
Hardware to a window/door is like the true engine oil, lubricant, wheels and parts which is to a car. You may choose the best, most durable, profiles and glass, but compromise to the hardware is critical to the life durability and functionality to the operations of the door/ window.
Factors to consider while specifying architectural hardwares for doors and windows
• Size of the window/door
• Weight of the window/door
• Static and dynamic load conditions on-site
• Safety and security requirements
• Atmospheric conditions, like corrosive environment at the point of use
• Profile dimensions like width, depth and, presence/absence of Euro Groove on profile
• Severity of recurrence of use per unit time interval
• Any special client specified requirements like night ventilation or ergonomic requirements, etc.
Type of hardware determines the profile to be used, not vice versa
The evolution of door and window hardwares over the past decade
Well, as concerned with the evolution, the growth of the uPVC Industry has driven the prices south and also increased the use of sliding windows especially in major parts of south and north India and least is taken into account for the hardware. Even now, some touch locks with absolutely least functionality are being used. Also, espags and locking devices and handles causing poor quality are frequently used in windows.
Latest technologies and materials for architectural hardware available in the Indian market
The entire range of products from around the world are fully available in India and also at most affordable prices. The inclination to use them by own choice is not moving ahead. I hope that after this disaster ‘Covid’, we could expect an accelerative movement to use the right hardware for the right applications.
Just to explain, for a 70 Kg door, two small rollers of Nylon which can hardly bear 20 kg cannot suffice. Similar are the examples applied for handles, friction hinges and espags of even quality of SS 304 vs SS 201 in use of friction stays. Mental awareness and consciousness must arise to use the best suitable, quality hardware.
Standards followed by architectural hardware manufacturers in India, to make sure that their products are of superior quality
Most of the hardware used or manufactured for uPVC or aluminium doors and windows come from Germany, Italy, Turkey Spain, France and China and are mostly top-end products, following best standards. Quality awareness is high among the users and fabricators.
All about customised architectural hardware & the advantages and hurdles façade regarding customisation
Customisation usually needs economies of scale and functionality. The total market in India for low-cost aluminum windows are still the highest. Therefore, cheaper, just operable, not the best functional hardware is used in a lot of projects.
Future of the hardware industry for façades and fenestrations?
The future is where people look for safety and security and more durable solutions. The fabricator needs to say ‘No’ to the lowest quote answers to their customers. Customers need to look for and should buy the most cost-effective yet durable and functional doors and windows with a focus on safety and security.
