Double Glazing Door Locks Many homeowners opt for double-glazed windows and doors due to their energy efficiency, insulation, and sound reduction. However, they can also be an effective deterrent for burglars. To increase the security of your double glazed windows, ensure that they have been equipped with anti-jemmy hinges. These special hardware components make it very difficult to pry the window sashes open. Multi-point locking Multipoint door locks are among the most effective security tools you can install in your home or workplace. They are nearly impossible for anyone to pick or break, and can be a fantastic addition to any security system. They also can improve the efficiency of your energy use by decreasing drafts around the door frame and enhancing the seal. Multi-point locking systems consist of a deadbolt as well as a live bolt (latch) coupled with hook bolts below and above the latch, and flush bolts that lock into the head and sill of the door frame. They typically extend across the entire width of the door or even more. In commercial contexts, these are called “full-width” systems due to the fact that they protect the entire opening. Multi-point locking is a feature on most uPVC and certain timber doors. This type of lock provides a higher level of security than conventional locks. It is typically described as a part of the Secured by Design initiative, that has been approved by the police. When a uPVC multi-point lock door is shut the handle on the outside will activate the latch bolt. The inside handle is locked by turning the lock's thumbturn inside with the door handle raised or by using keys. You should always use a key to lock your door once it's closed, as trying to force the deadbolt or latch bolt using a handle can damage the lock and the hinges. If your uPVC multi-point lock doesn't function correctly, it could be because it's not aligned properly with the door frame. You can check this by placing a spirit level on the top of the door and looking for gaps in the miter joints where the frame meets the door. If you notice a gap, it's worth getting your double glazing expert to look at the issue and resolve the issue. They can fix the lock or install a replacement. They'll be able to determine if it's caused by damage on the frame or lock unit. In these cases the technician will be able to repair or replace the multipoint lock to make it work again. Espagnolette locks Espagnolette locks have become a standard locking mechanism for double-glazed uPVC windows. They are easily identified by their flat strip shape which moves as you turn the handle. They are used with multi-point locks around the frame of your window to secure the window and lock it. If you are looking to improve your uPVC window, espagnolette handles can be used for new builds or renovations. They are available in a broad variety of styles, including period and contemporary. They also come with an array of bar sizes backset options, mushrooms cam heights, and a selection of profiles that can be used for every application. Although they are a very well-liked option, espagnolette locks have been criticized for delivering low levels of security to French doors. A single locking point in the middle of the door can be easily bypassed. It is also possible for burglars to open French doors by pushing the handle to the left or left. replace window lock of doors are often used as the primary entry point to your home, and must be secured to minimise the risk of unwanted entry. The espagnolette lock isn't a bolt, but an uni-piece mechanism that can be attached externally to the edges of French doors, or internally to an existing frame. The mechanism operates with a handle. It consists of a rod which has hooks at its head and sill. These hooks fit into sockets on the window frame. When the window's handle is turned on the rod is moved upwards and downwards. The hooks then lock into their receivers. They are a great option for those looking to increase the security of their French doors without compromising the aesthetic of the door or the overall appearance of the room. These handles can be paired with a variety of different designs and are able to be master keyed to give you added security. Like cockspur handles espagnolette handles are available in both crank and inline models, based on the orientation of your windows. Inline versions simply turn exactly the same way as the original handle, whereas the cranked versions are available in right and left handed designs. Laminated glass It is used as windows because it is extremely difficult to break. It is also much safer than standard glass because it fuses together into one single piece of safety glass, rather than shattering into loose sharp shards. This makes it perfect for commercial and residential properties. Lamination is a process which combines two pieces of glass with a plastic interlayer between. The entire piece is heated before being pressured to make it stronger enough to be used as windows or doors. The resulting laminated glass is up to 5 times stronger and 100 times stiffer than glass that has been tempered. It can also withstand more intense impacts, and resist weathering. This type of glass is ideal for buildings that must perform well, like enhanced security (impact-resistant glass) UV protection, or noise reduction. Laminated glass can be paired with high-performance coatings to improve the thermal insulation as well as solar control. It comes in a range of options to fit your needs and budget. As opposed to tempered glass glass is able to be cut after production and still be safe to use. It is also less likely to break when cut from the sides rather than the edge of the glass. This makes it an excellent choice for glass that doesn't open or close like cellar windows. It also helps reduce the noise that travels through high-rise structures. The Saflex PVB interlayer within the laminated glass also helps to block some of the sun's harmful UV rays, thus preventing discoloration of furnishings and fabrics. Although laminated glass is more expensive than tempered glass, it has many benefits that can reduce your costs over time. It's also more robust and resistant to abrasions and scratches and can be customized according to your specific requirements. It's also less susceptible to heat damage, making it an ideal option for coastal areas or high-rise structures. Certain building codes require that exterior doors and some interior windows are made from glass laminated. Friction hinges Friction hinges help hold in place doors panels, flaps and doors. They also can withstand the motion of other hinges and prevent an unintentional closing and opening. They are available in a variety of sizes and shapes. They can have different torques, which are the forces which determine how long the hinges can remain open or closed. Aluminum is a fantastic material for friction hinges due to its high strength-to-weight ratio, durability, and resistance to corrosion. It is also lightweight and easy to work with. It can also be made into a wide range of finishes and is simple to install and repair. Another popular material for friction hinges is brass. Brass is an alloy made of copper and zinc, and it has a natural resistance to corrosion. It is stronger and more durable than stainless steel, but is more expensive. The hinges that use friction in uPVC door systems that have double glazing are able to be customized according to the application. These customizations may include the amount of damping, the viscosity of the lubricant, the degree of tolerance for space between components, and environment in which the hinge will be utilized. These factors can impact the dynamic torque of the hinge and it is important to keep track of this metric in critical applications. There are a variety of friction hinges, such as one-way and detent. One-way friction hinges have constant torque in one direction, whereas detent friction hinges don't have any torque in the opposite direction. Other variations include disc, pipe and curl friction. Every type of friction hinge has its own set of properties that make it more or less efficient in particular applications. The hinges that are friction are commonly called 'free stop' hinges, because they permit the lid or door to remain at a predetermined angle after the force has been removed. This protects against injuries by preventing accidental closing. This type of hinge is perfect for use in medical, tough or dangerous areas. The hinges are able to be designed to allow different levels of free play and can be designed to function at a variety of angles.
