There are many factors to consider when choosing which upvc doors are best for your home or business, TWG can offer advice on the technical aspects of the door, door frame, locking and installation. One of the many reasons for replacing your existing doors with a upvc door is the excellent safety and security features offered by the very latest advanced door systems. Early uPVC frames offered very little in the way of resistance to potential burglars, with poor locking systems, external beads and frames without reinforcement. Thankfully things have moved on and True Window and Glass Centre would suggest that your new uPVC door should have the following: • At least 70 mm frames (the thickness back to front) that add improved stability and strength to pvcu doors • Internally glazed doors (sealed units installed into the frames from inside rather than outside) so that the glass is more difficult to remove from outside, without breaking it. • Multi-point, shoot bolt and hook bolt locking systems to deter or severely delay entry by a burglar.

Euro cylinder locks should be anti-snap, anti-bump and anti-drill certified. TWG recommend fitting at least a 3 star Kite marked Euro Cylinder lock to provide true resistance to snapping. • Doors should be fixed into the house walls with proper screw fixings, not just fixing foam, otherwise the whole frame could simply be cut away from the surrounding brickwork. • Door panels should be reinforced to prevent forced entry (twg fit reinforced as standard – some companies do not so please check!). Why Choose a PVCu Door? When considering the purchase of any door the main factor will inevitably be the cost of the materials. When it comes to pricing uPVC is usually cheaper than aluminium, timber or composite, but uPVC can mean quality and value with relative cost effectiveness being a bonus that makes a difference. Another hugely appealing feature of upvc doors is:- they are remarkably low maintenance. Aluminium is resilient, but still needs attention every now and then.

On the other hand, upvc never rots, flakes, rusts or fades. Apart from a quick wipe with a damp cloth to keep it clean, upvc requires virtually no maintenance making it very convenient and time-saving. Due to its resilient and robustness, uPVC is known to be very reliable and trustworthy when it comes to security. Modern doors have frames constructed to the utmost hardness and the True Window and Glass Centre fit a reinforced panel at no extra cost, making it extremely difficult to break through or damage. kitchen cabinet doors dublin irelandWhilst aluminium is generally more secure due to its strength -uPVC is not far behind and we also offer an upgrade to anti-snap, anti-bump and anti-drill 3 star Euro lock to prevent lock snapping.sliding door hardware nw

All our uPVC doors come with optional Part M compliant easy access low threshold option, ideal for wheelchair users and family homes as they create less of a trip hazard and make an easy access ramp for wheelchairs and pushchairs. PVCu is a very competent insulator and provides the best heat and energy insulation available and the ability to keep heat in and sound out is largely responsible for its popularity.lambo door kits for 2012 camaro TWG specialise in supplying hardware and replacement parts for PVCu doors – handles, hinges, locks, keeps, key cylinders, multi-point door locks and door furniture such as letterboxes, door knockers, door restrictors, door hinges, etc. blinds for patio door irelandWe are often able to supply and source parts for older doors fitted over the past 25+ years.lowes garage door opener installation charge

We also stock hardware for aluminium windows, doors and patio doors. What is the difference between uPVC and PVCu? The simple answer is it is the same thing – most European languages place the noun (the word PVC in this case) before the adjective (U) giving the term pvcu, the term ‘upvc’ is more common in the UK.hollow metal doors nj uPVC, also known as rigid PVC, is extensively used in the building industry as a low-maintenance material and is available in a range of colours and finishes, and is increasingly used as a substitute for wooden window frames and sills when installing double glazing in new buildings. frameless shower door standard widthOther uses include fascia, and soffits and guttering. PVCu is known as having strong resistance against chemicals, sunlight, and oxidation from water.

TWG–The Wise Choice for uPVC DoorsLocking mechanisms on doors are varied and it can be difficult to judge whether what you have is good, bad or indifferent. This information takes you through the common types of door locks for PVCu doors. Ultimately what you need is a combination of locking mechanism that gives you flexibility and convenience for entering and exiting your property, but also providing you with additional security at night time or if you are away on holiday. Whenever you move house and inherit somebody else’s security choices you should ensure that what you have meets your needs and ultimately provides you with the most appropriate security level versus your budget. Generally speaking a multi-point lock that has a number of locking points along the edge of the door. These locking points are centrally controlled and engage when the handle is lifted/ thrown securing it to the frame. Multi-point locks can use a combination of latches, hooks, rollers, mushrooms and bolts;

and as standard are operated with a Euro Cylinder. Is a new multi-point lock solution that offers all the benefits of multi-point locking - rollers, mushrooms, hooks and bolts; but removes the vulnerable cylinder thereby overcoming all associated issues – No Cylinder, No Problem! The Vectis lock has been designed to overcome the associated problems with cylinders by  using levers instead of traditional and trusted mortice locks with anti-jemmy multiple locking points along the whole face of the door. The dimension from the lock faceplate to the centre line of the cylinder or keyhole.(This definition is different for traditional mortice locks) The dimension between the lock spindle and the centre of the keyway of the gearbox. Centres can vary between lock systems, though typically, the UK standard is 92mm. Older lock types do have different centres. Understanding the lock centre dimension is critical for specification of the correct handle. See also Offset Spindle configuration.

A standard size feature within PVCu doors (16mm) that accepts the locking hardware. The location of the eurogroove within different profiles (the plastic of the door) will vary, hence the requirement for a variety of handle spindle lengths. The metal part o f the lock that is visible on the edge of the door leaf. These can vary in width to suit the application. 16mm is typical for PVCu to suit the eurogroove channel, 20mm is common for timber and composite doors. The chamfered part of the lock usually in the central gearbox, which initially engages to hold the door in the closed position when shut. The latch is spring loaded and retracts when it makes contact with the striking edge of the keep, and then extends when aligned with in the keep. Latches are typically deadlocked once the lock is fully engaged (locked) and are reversible by removing the screws on the external face of the latch and then rotating the latch – screws are then re-inserted. A plastic part on the lock that allows the latch to be held in its withdrawn position, thus preventing it engaging within the keep.

This is normally used in conjunction with a nightlatch (lever/pad) facility to temporarily prevent the door from being locked when closed. Hooks provide a steadfast locking point for a door. When thrown they extend into the keep and due to their shape and the geometry of movement, engage behind the keep plate to provide anti separation. Some multi - point locks have hooks that throw /move in the sam e direction, and whilst this provides resistance to horizontal separation, there is less resistance to lifting the door. Bi-directional hooks (movement in opposite directions) provide the optimum security as they effectively clasp the leaf into the outer frame. Linear bolts extend horizontally into the keep, with greater penetration than a roller and can be effective for door sets with small gaps (4mm or less) between the frame and the door. Rollers are often used for weathersealing on PVCu doors; and are a cylindrical shape. They generally also often an adjustment feature to enable the compression of the sash against the frame to achieve the appropriate weatherseal.

Mushrooms have an element that interlocks within its keep to provide separation resistance of the sash from the frame. Keeps are fitted to the door frame and the moving parts of the lock (hook, linear bolt or cam) locates into these when in the locked position. They often feature adjustable plates or pockets to allow for adjustment of the door once fitted. Keeps for roller cams usually feature a chamfered (angled) edge, to guide them into the keep (reducing the closing force required). The square section drive bar, usually 8mm in width, which is positioned through the drive of the lock and locates into the handle set levers, or pads. Rotation of the lever/pad rotates the spindle, which in turn operates the drive (follower) of the lock. The length of the spindle is dependent upon the thickness of the door and depth of the handles lever. Gives the option for the entry into the house from outside requiring a key, even when the lock has not been fully engaged, this is to replicate the operation of a traditional nightlatch.

Gives you the nightlatch function on certain types of locks. The spindle is split, so that depressing the handle on the outside of the door does not retract the latch. An alternative mechanism to the split spindle for providing a nightlatch function. An offset spindle lock has two drives, one of which retracts the bolts/ rollers/ hooks and latch, and one that will only retract the bolts and not the latch. Typically in the UK the centres are set at 92 mm and 62mm . Used in conjunction with a handle where the inner and outer levers or pads are offset, so that the external handle will not retract the latch, the night latching function is achieved. Multipoint lock gearboxes can be either sprung or unsprung. With a sprung gearbox, the drive mechanism is spring loaded, so that when the lever is depressed and released, the handle and latch are returned to their original (at rest) position by the spring within the gearbox. Unsprung gearboxes require the use of sprung handles (handle sets with spring cassettes) to return the lock drive from the depressed position, thus re-engaging the latch.

Spring cassettes are also used in certain handles, where the weight of the lever is too great to allow the integral spring within the gear box to operate effectively in isolation. This is typically the case with solid cast levers and extended levers for disability use. The rotating operating element of the handle . Handle designs can vary f rom plain straight levers, to decorative swan neck, twist and contemporary designs. Additionally, extended levers can be used for disability complaint applications to reduce operating forces of the lock operation. A handle type, typically used with offset or split spindle operation (though not exclusively) that is designed to mimic a traditional knob aesthetically, whilst having conventional lever operation. The element of the handle that is fixed to the door. Back plates can be face fixed, i.e. the inner and outer handle screw into the face of the door independently, though most multipoint handles use bolt through handles, where the outer back plate has a screw lug for receiving the screw fixing from the inner handle.

Has a central cam that rotates, upon turning of the key to operate the lock mechanism. Cylinders are available in a number of profiles, though the Europrofile and Oval shapes are by far the most common for single point locking mechanisms. Cylinders can be supplied with a thumbturn fixture on one side to enable operation of the lock without the use of the key from one side of the door. The security of a lock cylinder can vary greatly, with options for the number of differs, drill resistance, plug extraction, pick, bump and snap resistance all being options. Additionally, a number of supplementary hardware devices have been engineered to provide additional resistance to attack, including cylinder guards and security handles. A feature of higher security locks and cylinders, that resists forced entry through attack by drilling of the cylinder mechanism or lock case. A plate used to cover a functional element of the lock, usually the cylinder or lever key way.
