10 Tell-Tale Signs You Need To Find A New Double Glazing Door Lock Double Glazing Door Locks

Many homeowners opt for double glazed doors and windows for their insulation, energy efficiency and sound reduction. However, they are also an effective deterrent against burglars.

To enhance the security of your double-glazed windows, check that they have been fitted with anti-jemmy hinges. These hardware parts are specially designed to make it extremely difficult to pry the sashes of your windows open.

Multi-point locking

Multipoint door locks can be one of the most efficient security tools you can put in your office or home. They are nearly impossible to pick or break and are an excellent option to add to any security system. They can also boost the efficiency of your energy by reducing drafts and improving the seal around the door frame.

Multi-point locking systems consist of a deadbolt as well as a live bolt (latch) joined by hook bolts below and above the latch, and flush bolts that lock into the sill and head of the door frame. They generally extend most of the time, but they are not all across the entire width of the door. These systems are known as "full-width", in commercial contexts. They secure the entire opening of the door.

Multi-point locking is offered on the majority of uPVC and some doors made of timber. This type of lock provides a higher level of security than regular locks. It is often described as a part of the Secured by Design initiative, which 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 make use of a key when you lock your door. The use of a handle to lock the door could damage the latch or deadbolt.

If your uPVC lock is not working properly, it could be that it's not aligned with the door frame. You can check by placing a spirit-level over the top of the doors, and then looking for gaps at the miter joints.

If you find a gap, it's worth getting your double glazing specialist to look at the issue and resolve the issue. They'll be able to replace the lock for you or install a new one. They'll know whether the issue is due to damage to the frame or the lock unit itself. In this case they'll be able repair or replace your multipoint lock to make it work again.

Espagnolette locks

Espagnolette locks are now a standard locking mechanism for double-glazed uPVC windows. The flat strip shape that rotates when you turn the handle is a great way to recognize them. They work using multi-point locks within the frame of your window to lock and unlock it safely. If you are seeking to improve your uPVC windows, the espagnolette handles are a good choice for new constructions or renovations. They are available in a variety of period and contemporary styles and come in a range of bar lengths, backset options and mushroom cam heights with a variety of profile keepers to fit all kinds of applications.

Although they are a very well-liked option the espagnolette locks have been criticized for providing low levels of security to French doors. With only one point of locking in the middle of the door can be bypassed with enough force. It is also possible for thieves to open French doors by bending the handle to the right or left. These doors are often used as a main entrance to your home and should be kept secure to reduce the chance of unauthorized entry.

The espagnolette lock is not an actual bolt, but rather it is a single-piece mechanism that can be fitted externally on the edge of French doors or internally to an existing frame. The mechanism is operated via a handle and comprises of a rod that has hooks at the head and at the sill that fit into sockets in the window frame. When the window's handle is turned on the rod is moved up and down. The hooks then lock into their respective receivers.

They are a great option for those looking to enhance the security of French doors without compromising on the design and aesthetics of the door. These types of handles can be paired with a range of other styles and can even be master keyed for added peace of mind.

Like cockspur handles, espagnolette handle are available in both crank and inline models based on the orientation of your windows. double glazing window lock replacement move in the same direction as the original. Cranked versions come in both right-handed and left-handed options.

Laminated glass

It is often used for windows because it is extremely difficult to break. It is also safer than regular safety glass since it is fused together into a single piece rather than breaking into sharp fragments. This makes it ideal for commercial and residential properties.

Lamination is the process of combining two pieces of flat glass with an interlayer of plastic. The whole piece is then heated and put under pressure to make it stronger enough to be used as windows or doors. The resulting laminated glass is five times stronger and 100 times more rigid than glass that is tempered. It also can endure more severe impacts, and withstand weathering.

This type of glazing is ideal for structures that require high-performance like increased safety (impact resistant glass) and UV protection, as well as noise reduction. Laminated glass can be paired with a high-performance coating in order to increase thermal insulation and solar control. It's available in a wide range of choices to meet your budget and project.

Laminated glass is safer to use than tempered glass since it is able to be cut even after production. It is more likely to not shatter if 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 can also be used to reduce the sound that travels through high-rise structures. The Saflex PVB layer in the laminated glasses also assists to block harmful sun ultraviolet rays. This prevents discolouration of furniture, fabrics, and other objects.

While laminated glazing is generally more expensive than tempered glass, it offers numerous advantages that could save you money over the long term. It's also more robust, resistant to abrasion and scratches and can be customized to your specifications. It is also less susceptible to heat damage, making it an ideal option for coastal areas and high-rise buildings. In fact, certain building codes require that all exterior doors and some interior windows be made from laminated glass.

Friction hinges

Friction hinges are designed to support and maintain the positions of doors and flaps, panels and windows. They also impede the movement of other hinges and stop hard slamming or unintentional closing and opening. They are available in various dimensions and shapes, and they can be equipped with a variety torques. These forces determine how long hinges stay open or closed.

Aluminum is an excellent material for friction hinges because of its strength, durability, resistance to corrosion and high strength-to-weight ratio. It is also lightweight and easy to work with. It can also be crafted into a variety of finishes, and is simple to install and repair. Brass is another popular material that is used in friction hinges. Brass is an alloy of zinc and copper, and it has a natural resistance to corrosion. It is more durable and stronger durable than stainless steel, but is more expensive.

The hinges with friction that are used in uPVC double glazing door systems can be customized to meet the specific needs of the particular application. These customizations could include the amount of damping, lubricant viscosity and the degree of tolerance between components. They may also include the conditions of the environment in which the hinge is used. These factors can impact the dynamic torque of the hinge and it is crucial to keep track of this metric in critical applications.

There are a variety of friction hinges, including one-way and detent. One-way friction hinges are characterized by constant torque in one direction, while detent friction hinges have no torque in the opposite direction. Other variations include disc, pipe, and curl friction. Each type of hinge is distinct and has its own set of properties, which make it more or less suitable for certain applications.

Friction hinges are also referred as 'free-stop' hinges because they permit a door or lid to remain at an angle after the force has been removed. This helps prevent injuries through accidental closing. This type hinge is suitable for use in harsh, medical or hazardous environments. The hinges can be configured to provide different levels of free play and can be designed to work in a range of angles.
