Double Glazing Door Locks Many homeowners opt for double-glazed doors and windows for their energy efficiency, insulation and sound reduction. However, they can also be an effective deterrent against burglars. To ensure the security of your double-glazed windows, ensure that they are fitted with anti-jemmy hinges. These special hardware components make it very difficult to get the sashes of your windows open. Multi-point locking Multipoint door locks are one of the most secure security devices you can install at your workplace or in your home. They are almost impossible for anyone to pick or break, and can be a great option to add to any security system. They also can improve your energy efficiency, by cutting down on drafts in the doorframe 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 secure the head and sill of the door frame. They typically extend the most, if not all across the width of the door. In commercial contexts, these are known as “full-width” systems due to the fact that they protect the entire opening. The majority of uPVC doors come with multi-point locking, however some timber doors are also equipped with this level of security. This type of lock offers an increased level of security compared to regular locks. It is typically specified as part of the Secured by Design initiative, that has been approved by the police. When a uPVC window with a multi-point lock is closed, the outside handle operates the latch bolt. The inside handle can be locked by turning the thumbturn on the inside while the door handle is raised or using the lock key. Always use a key to lock your door. Using an outside handle to lock the door can cause damage to the latch or deadbolt. If your uPVC lock isn't working properly, it could mean that it is not aligned with the frame of the door. You can check this by placing a spirit level on top of the door and checking for any gaps in the miter joints at the point where the frame connects to the door. If you do find gaps it's worth contacting your double glazing specialist to look at the issue and resolve the issue. They can fix the lock or install a replacement. They'll be able to tell whether the issue is caused by damage to the frame or the lock unit itself. In these cases, they'll be able to repair or replace your multipoint lock to make it work again. Espagnolette locks Espagnolette locks are one of the most popular window locking mechanisms that are used for modern uPVC double-glazed windows. The flat strip shape that moves when you turn the handle is a good method to identify them. They are used with multi-point locks around the frame of your window to lock and unlock it safely. If you're looking to improve your uPVC window handles, espagnolette handles are used to build new windows or for renovations. They are available in a variety of contemporary and period styles and come in a variety of bar lengths, backset options and mushroom cam heights with a choice of profile keeps to suit the majority of applications. While they are a popular choice, espagnolette locks have been criticized for delivering inadequate security for French doors. The single point of locking in the middle of the door is easily overcome with enough force. In addition, it is fairly easy for thieves to open your French doors by forcing the handle to the left or right. These doors are often the main entrances to your home, and should be secured to reduce the chance of intrusion from outside. The espagnolette lock isn't bolt-like, but is a single-piece mechanism which can be fitted externally to the edge of French doors or inside a casement frame. The mechanism is operated by a handle, and consists of a rod that has hooks at the sill and head that fit into sockets in the window frame. When the window's handle is operated the rod is moved up and down. The hooks are then locked into their receivers. They are a great solution for those who wish to improve the security of French doors without compromising on the appearance of the door. These handles can be paired with a range of other designs and are able to be master keyed for added security. visit the website to cockspur handles espagnolette handles are available in both cranked and inline models to match the orientation of your window. Inline versions move in the same direction as the original. Cranked versions come in both right- and left-handed versions. Laminated glass Laminated glass is commonly used for windows since it is extremely hard to break. It is also safer than standard safety glass because it is fused together into one piece instead of breaking into sharp fragments. This makes it perfect for residential and commercial properties. Lamination is a process that involves the joining of two pieces of flat glass with a plastic interlayer in between. The whole piece is then heated and put under pressure to make it strong enough to be used as windows or doors. The laminated glass that results can be up to five times stronger and one hundred times stiffer than tempered. It also can be able to withstand more severe impacts and withstand weathering. This type of glass is ideal for buildings that need to perform well, like enhanced safety (impact-resistant glass), UV protection, or noise reduction. Laminated glazing can be combined with a high-performance coating to increase thermal insulation and solar control. It's available in a variety of options to fit your budget and project. Unlike tempered glass, laminated glass is able to be cut after production, and be safe to use. It is more likely to not shatter when cut from the side instead of the edge of the glass. This makes it a great choice for glass that does not open or close, such as cellar windows. It is also utilized in high-rise structures in urban areas because of its ability to reduce the amount of noise that flows from the street to the interior of the. The Saflex PVB interlayer within the laminated glass is also able to block some of the sun's damaging UV rays, which prevents discoloration of furniture and fabrics. Although laminated glass is more expensive than tempered glass, it offers many advantages that will save you money over time. It's also more durable and resistant to scratches and abrasions. It can be manufactured according to your exact specifications. Additionally, it's less susceptible to heat damage, and is a great option for coastal areas and high-rise buildings. In fact, some building codes require that all exterior doors and some interior windows be made of laminated glass. Friction hinges Friction hinges support and hold doors panels, flaps and doors. They can also impede other hinges' movement and prevent slamming hard as well as accidental closing and opening. They are available in a variety of shapes and sizes. They also have different torques which are the forces which determine how long the hinges can remain open or closed. Aluminum is a great material for friction hinges because of its durability, corrosion resistance and high strength-to-weight ratio. It is light and easy to handle. It can also be crafted into a variety of finishes, and is easy to set up and repair. Brass is a different material that is widely used for friction hinges. Brass is an alloy made of copper and zinc which has a natural resistance to corrosion. It is more durable and stronger durable than stainless steel, but is more expensive. The hinges made of friction used in uPVC door systems with double glazing are able to be customized in accordance with the requirements of the particular application. These modifications can include the amount damping, lubricant viscosity and the degree of tolerance between the components. They can also be influenced by the environment where the hinge is used. These factors can impact the dynamic torque of a hinge. It is important to keep track of the metric in crucial applications. There are a variety of friction hinges including one-way and detent. One-way friction hinges have constant torque in one direction, whereas detent friction hinges do not have torque in the opposite direction. Other variations include curl, disc and pipe friction. Each type of friction hinge has a unique set of characteristics that make it more or less useful in specific applications. Friction hinges are also referred as 'free-stop' hinges because they allow a door or lid to remain at an angle after the force has been eliminated. This protects against injuries by preventing accidental closing. This kind of hinge is perfect for use in medical, tough or hazardous locations. The hinges are able to be designed to provide different levels of free play and are able to function in a variety of angles.
