Double Glazing Door Locks Many homeowners choose double-glazed windows and doors for their energy efficiency, insulation and sound reduction. upvc window lock repairs near me repairmywindowsanddoors.co.uk are also a powerful deterrent to burglars. Check that your double-glazed windows have anti jemmy hinges to improve their security. These hardware parts are specially designed to make it very difficult to open the sashes of your windows open. Multi-point locking Multipoint door locks are among the most secure security devices you can put in at home or at work. They are almost impossible to break or pick and are an excellent addition to any security system. They can also improve your energy efficiency by reducing drafts around the doorframe and improving the seal. Multi-point locking systems are composed of a deadbolt and a live bolt and hook bolts located above and beneath the latch. They also include flush bolts that lock into the head of the door and the sill. They usually extend most if not all across the entire length of the door. These systems are referred to as “full-width”, in commercial contexts. They secure the entire opening of the door. The majority of uPVC doors are equipped with multi-point locking, but some timber doors are also offered with this level of security. This type of lock offers greater security when compared to regular locks. It is often described as a part of the Secured by Design initiative, which has been approved by the police. If a uPVC door that has a multi-point lock is closed the handle on the outside turns the latch bolt. The inside handle is locked by turning the lock's thumbturn on the inside of the door with the handle raised or using a key. You should always use a key to lock your door when it is closed, since trying to push the deadbolt or latch bolt using a handle can cause damage to the lock and hinges. If your uPVC multi-point lock isn't functioning properly it could be due to 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 connects to the door. If you notice a gap it's worth contacting your double glazing specialist to have a look and fix the problem. They'll be able replace the lock on your behalf or install a new one. They'll be able to tell whether the issue is due to damage to the frame or the lock unit itself. In such cases the technician can repair or replace the multipoint lock in order to restore it's functionality. Espagnolette locks Espagnolette locks are among the most commonly used window locking mechanisms used in modern uPVC double-glazed windows. They can be identified by their flat strip shape which moves as you turn the handle. They work in conjunction with the secure multi-point locks that are positioned around the frame to firmly lock and unlock your windows. If you're looking to improve your uPVC window, espagnolette handles can be used for new builds or for renovations. They are available in a variety of period and contemporary styles and come in a range of bar lengths, backset options and the heights of the mushroom cams, with a choice of profile keepers to fit most applications. The espagnolette lock is a popular option, but it has been criticized for offering an inadequate security level on French doors. A single lock point in the middle of the door can be easily bypassed. In addition, it is relatively easy for thieves to gain access to your French doors by bending the handle to the left or right. These doors are often the main entry points into your home, and should be secured to minimize the chance of intrusion from outside. Although they are referred to as espagnolette locks, these locks are not a bolt but actually a one-piece mechanism that can be mounted externally on the edges of your French doors or inside a frame for a casement window. The mechanism is operated by an handle. It consists of a rod with hooks at its sill and head. These hooks fit into sockets on the frame of your window. When the handle is turned the rod is moved upwards and downwards, and the hooks lock into their receivers, allowing them to lock and unlock your windows. These are an excellent solution for those who wish to enhance the security of French doors without compromising the aesthetics of the door. These types of handles can be used with a variety of other designs and are able to be master-keyed for extra peace of mind. Like cockspur handles espagnolette handles are available in both crank and inline models depending on the orientation of your windows. Inline versions simply turn in the same manner as the original, while cranked versions are available in both left and right handed versions. Laminated glass Laminated glass is commonly used for windows since it is extremely difficult to break. It is also more secure than regular glass since it fuses together into one single piece of safety glass, rather than breaking into sharp, loose fragments. This makes it perfect for residential and commercial properties. Lamination is the process of joining two pieces flat glass and an interlayer of plastic. The entire piece is heated before being pressured to make it stronger enough to use as a door or window. The resulting laminated glass is up to 5 times stronger and 100 times stiffer than glass that has been tempered. It also withstands greater impacts and is resistant to weathering. This type of glass is ideal for buildings that have to perform well, such as enhanced security (impact-resistant glass), UV protection, or noise reduction. Laminated glazing can be used with a high-performance coating to increase thermal insulation and solar control. It is available in a variety of options that will fit your budget and project. Laminated glass is more secure to use than tempered glass as it is able to be cut even after the production. It is also less likely to break when cut from the side rather than the edge of the glass. This makes it a good option for glass that does not open or close, such as cellar windows. It is also used to reduce the noise that travels through high-rise buildings. The Saflex PVB interlayer in the laminated glass helps to suffocate some of the sun's harmful UV rays, preventing discolouration of furniture and fabrics. Although laminated glass is more expensive than tempered, it offers many advantages that can save you money over time. It's also more durable and resistant to abrasions and scratches. It can be made according to your exact specifications. It's also less prone to heat damage and is a great choice for high-rises and coastal areas. Some building codes even require that exterior doors and certain windows inside are made of laminated glasses. Friction hinges Friction hinges support and hold in place doors, flaps and panels. They can also impede the movement of other hinges and prevent slamming hard and unintentional closing and opening. They come in a variety of sizes and shapes, and they are able to have a variety of torques. These forces determine how long the hinges remain open or closed. Aluminum is a great material for friction hinges due to its strength-to-weight ratio that is high, durability, and resistance to corrosion. It is also light and easy to work with. It can also be crafted into a variety of finishes and is easy to install and repair. Brass is another popular material used for friction hinges. Brass is an alloy of copper and zinc which is naturally resistant to corrosion. It is also stronger and more durable than steel, however it is more expensive. The hinges with friction that are used in uPVC double glazing door systems can be customized to meet the requirements of the particular application. These modifications can include the amount of damping, the viscosity of the lubricant as well as the amount of space tolerance between components, as well as the conditions in which the hinge is used. These factors can impact the dynamic torque of hinges. It is essential to be aware of the metric when in critical applications. There are a variety of friction hinges, such as one-way and detent. Detent friction hinges do not have torque in the reverse direction. Other variations include discs pipe, and curl friction. Each type of hinge is distinct and has its own set of characteristics, making it more or less useful for certain applications. Friction hinges are also known as 'free-stop' hinges because they allow the lid or door to remain at an angle even after the force has been eliminated. This prevents injuries by preventing accidental closing. This kind of hinge is perfect for use in medical, tough or dangerous environments. The hinges can be configured to have different degrees of free play and can be designed to function at a variety of angles.
