Frequently Asked Questions

Yes, if they are used sparingly. Muted finishes such as graphite or Velvet grey are suitable for a particularly calm look; Black sets more deliberate accents.

To disinfect a door handle set, you need a virucidal disinfectant for surfaces and disposable wipes - such as from a kitchen roll.
In the first step, wet the door handle completely with disinfectant. The areas where the palm of the hand rests on the door handle are particularly important. For WC sets, do not forget the WC lock. 
Afterwards, the disinfectant must act according to the manufacturer's instructions. Follow the respective product instructions.
Finally, wipe the surface with the disposable cloth. When doing so, avoid rubbing the cloth back and forth on surfaces that have already been disinfected and avoid using the cloth several times.
To ensure that the surface remains beautiful after frequent disinfection, it can be wiped with water or soapy water. Disposable cloths should also be used for this purpose. Throw the water away afterwards.

Yes, especially for heavily used Doors. Only apply a small drop. Too much will gum up the mechanism.

In principle, it is possible to retrofit a tight-closing system on sliding doors. There are ready-made sets with rubber bands to stick on. Of course, you can also ask a specialist for help. At Griffwerk, the sealing system is permanently built into the product. Therefore, retrofitting is not possible.

The weight of a sliding glass door varies from door to door and depends on the dimensions and type of glass. We therefore have a few examples for you: Sliding doors measuring 935x2058x8mm (for example, our Lines Four 503 sliding glass door made of toughened safety glass) have a surface area of 1.94 m². This weighs around 39 kg. A wider sliding glass door (1060x2058x8mm) is slightly heavier at approx. 44 kg. Sliding doors for high rooms (935x2183x8mm) are in the middle at around 41 kg.

High-quality sliding doors are best purchased from a specialist dealer. You can also purchase sliding doors from GRIFFWERK from our contractual partners in the online store.

Toughened safety glass or laminated safety glass. The former is heat-treated glass with increased impact and shock resistance. In the event of breakage, small, blunt shards are produced.

If the sliding door is to be particularly robust, we recommend LSG PRIME DOORS. They consist of two thermally toughened safety glasses and an inner tear-resistant film. In the event of breakage, the shards adhere to this intermediate layer. In addition, LSG prime glass has sound-absorbing properties.

The bathroom has long since evolved into a place that goes far beyond mere personal hygiene. Whether you linger in a relaxing tub bath in the evening or enjoy individual wellness rituals, your well-being depends on both privacy and a stylish ambience. This is where Glass doors come in as an ideal solution, offering a versatile choice with a Width range of glass designs. Glass doors with frosted glass look are very popular and have almost become a traditional element. The matt finish provides perfect privacy, allowing you to fully enjoy your bathroom in a personal and intimate atmosphere. Satin frosted glass can also be designed with artistic patterns or motifs, depending on your taste. Here, there are hardly any limits to your individual preferences and requirements. If you want to create a more lively atmosphere in the bathroom, you can opt for Glass doors with colored lacquer. These are completely opaque and can act as vibrant color accents.

Glass doors can also be subsequently satinized. By laser or sandblasting the glass becomes milky and opaque.

Glass doors are tested for burglar-resistant properties in accordance with DIN EN 1627/1630.

Yes, Glass doors are a stylish option for cabinet doors and can reveal the contents.

LSG prime glass doors can withstand a lot. This is already due to the fact that the door leaf is made of two TSG panes. LSG has a significantly higher stability than normal float glass. For example, the bending strength alone is three times as high. The impact and shock resistance is also significantly better. These properties are achieved by a thermal pre-treatment of the ready-cut TSG pane. The glass is heated and then cooled relatively quickly. Two different tensions are created in the glass. There is compressive stress on the inside and tensile stress on the surface. Unfortunately, these stress conditions also have disadvantages, because TSG becomes very sensitive at the edges. The edges are actually the weakest point of a pane. This also applies to LSG glass doors.

LSG doors are more expensive than TSG doors. After all, the manufacturing process is much more complex. If you have to pay closer attention to your budget, you can only use LSG doors where extra safety is particularly important. This is the case in some rooms, for example on staircases where there is a risk of tripping, in narrow corridors, in bathrooms (where floors can become slippery), at room transitions where there can be strong draughts and, in general, always in places where people who are in particular need of protection, such as children or elderly people, are present. In any case, only doors made of safety glass should be used - regardless of whether they are TSG or LSG. We offer many designs in both types of glass.

As a rule, LSG panes are 8.8 mm thick. However, the thickness of our LSG glass doors depends on the format. For larger formats, we recommend a thickness of 10.8 mm.

Lockable window handles are suitable as an additional means of burglary protection or child safety. Whether plastic windows or noble wooden frames - whether plain silver or noble brass look - in our Griffwerk range you will find the right lockable window handle for every window variant. Ask your specialist dealer about Griffwerk products.

The window handles from Griffwerk can be individually matched to other design elements. Choose your window handle in the same look as your door handle or show your colours and surprise with strong contrasts: At Griffwerk, every taste will find what it is looking for.

As a renowned manufacturer of handles of all kinds, we at Griffwerk always try to cater to individual needs. Griffwerk window handles can be made with different square spindle lengths and can therefore be used in any window frame. On request, we produce special designs with variable pin lengths. Contact us!

When choosing a window handle, consider to which side you have room to turn and to which side the window should open. Window handles for windows that are opened and closed often need to be more durable and fit better in the hand than those that are rarely used. Window handles should match the material, shape and color of the existing door handles and hardware or those being purchased. If the window is located on a poorly visible corner, on a lower floor or in the children's room, you should think about lockable window handles.

Yes, there are different types of window handles that are suitable for different window types and styles. For example, there are window handles for swing windows, pivot windows, tilt windows, etc.

Plastic window handles are cheaper than stainless steel handles. Brass, stainless steel, aluminum or chrome wears out less. The interior style also affects the choice of window handles: For example, in an Art Nouveau room, an ornate brass handle would be better than a no-frills black window handle.

Yes, there are special window handles suitable for people with handicaps, for example those with larger levers or automatic opening mechanisms - Griffwerk does not offer these.

Window handles are fixed to the window frame with the help of a 7 mm square pin. The thickness of the window determines how deep the square spindle must be pushed into the window in order to lock it optimally.

We recommend the following trick for measuring: Take a thin object, e.g. a knitting needle, and push it into the opening as far as it will go. Mark the spot with your fingernail or tape. Then measure the distance with a tape measure.

Yes, you can replace glass fittings for glass doors yourself. A Phillips or slotted screwdriver and, if necessary, a hexagonal wrench and a drilling template are sufficient in most cases to change glass fittings.

LSG doors can be used for glass door systems with clamp mounting SENSA by GRIFFWERK. The inner foil is only slightly elastic. We nevertheless recommend readjusting the screws of the fixing after some time and later if necessary. Glass doors, like wooden doors, can adapt to changing room conditions and thus change. Please refer to the respective product data sheets for detailed information.

Glass fittings are made of sturdy material, such as metal, stainless steel, brass or aluminum.

When cleaning glass fittings, water with a little washing-up liquid is often sufficient as a cleaning agent. After wiping with a towel, always dry well to avoid rust.

A whisper latch is a door latch that has been partially coated with plastic. The plastic dampens the impact of the metal latch in the lock. Doors can thus be closed "whisper quietly". Whisper latches are available for door handles for wooden doors as well as for glass lock cases on all-glass doors.

To ensure that doors stay open or to protect against a hard impact, it is worth using a doorstop. Especially for glass doors, which break more easily if hit too hard. The door leaf and wall are thus not damaged. Glass doors in particular are protected with a doorstop.

Floor and wall door stops: To prevent the door from hitting the wall, door stops are fixed to the floor or wall. They are screwed or glued to the wall. Some are also equipped with magnets to stop the door. There are also floor doorstops that hold the door open by their own weight without being fixed. Door wedges are only placed on the floor and thus prevent the door from falling into the lock unintentionally. Risk of breakage: Door wedges should not be used for glass doors. Soft rubber door stops are suitable for glass.

Doorstops are often made of silver stainless steel. Door stops made of plastic are available in almost all colours. For a harmonious overall appearance, it is worth considering the colour of the glass door and the door fittings.

There are heavy doorstops made of metal that stop doors based on their own weight and can weigh up to a kilo or more. Door wedges made of plastic or wood weigh only a few grams. As with door stops that are screwed into place, the weight does not matter because they are fastened with screws or wedged in place.

Door stops can be made of stainless steel, metal, plastic, rubber or silicone. Door wedges are often made of wood as well as plastic. Sack-like door stops that are placed on the floor are usually made of fabric.

A security upgrade in rented flats, like all changes affecting the building fabric, must be agreed with the owner. It makes sense to obtain written permission, which also excludes the obligation to dismantle the building when moving out. Ideally, change requests can be clarified before the tenancy agreement is signed.

Never just pull the front door closed. Under certain circumstances, they are legally considered to be unlocked. In order to benefit from insurance cover in the event of damage, it is worth checking with your insurance company. Take this opportunity to clarify whether the resistance class of the protective fittings is sufficient.

A security fitting is mounted on the front door and protects the profile cylinder and mortise lock from mechanical impact. This means that the lock cannot be broken open without considerable force - which deters burglars because it costs them time. The goal: to protect your house or flat from unwanted intruders.

Good security fittings are labelled with the manufacturer's name or mark, the resistance class and the test number. They are marked with the corresponding test and inspection mark.

Anyone who wants to provide additional protection for their home or property can take one of the following special measures. GRIFFWERK does not sell these products, please contact an appropriate specialist dealer if you are interested.  

• Multi-point lock: A multi-point lock is an alternative to the mortise lock that secures the front door with up to 7 locking elements.  
• Hinge side security: With hinge side security, several toothed elements interlock in order to keep the attack surface for mechanical effects as small as possible. 
• Sturdy striking plate: High-quality striking plates allow the deadbolt and latch of the mortise lock to engage when the front door is closed.
• High-quality locking cylinder: A burglar-proof locking cylinder ensures increased security through drilling and picking protection. 
• Stable door hinges: Door hinges connect the door frame or frame and the door leaf - similar to a hinge. Deeply anchored door hinges protect against the door being prised open.

Protective fittings protect doors, locking cylinders and handles against manipulation from the outside. They are composed of an inner shield with a door handle or door knob and a resistant outer shield to which a knob, handle or door lever is attached. Screwed from the inside, protective fittings have no attack surface for burglars: nothing sticks out that can be broken off or twisted or pulled out.

Stand on the visible hinge side, not on the lock side. Hinges left = DIN left, hinges right = DIN right. Photograph the side so that everything remains clear.

BB indicates the classic keyhole, PZ indicates the cylinder opening, and WC indicates the olive with emergency release. Also check the door usage. This will help you choose the right type of lock.

72 mm dominates on Internal doors; 92 mm is suitable for PZ locks and Security door handles on residential and Entrance doors. Both dimensions describe the distance between the center of the square and the center of the keyhole. Measure exactly, otherwise the fitting will not fit.

Start with fittings in harmonious finishes, refurbish existing doors, selectively insert Glass doors. Less, but high quality is typical of lagom.

Maintain matt finishes and Satin frosted Glass regularly with mild cleaners, use microfiber. In this way, the calm, high-quality appearance is permanently maintained.

Reduced, ergonomic forms with matt or brushed finishes; preferably in unagitated tones such as graphite, warm Grey or elegant patinated metal nuances.

Hygge emphasizes cosiness, Scandi often brightness and design icons. Lagom focuses on the "golden mean": sufficient, functional, unagitated - even when it comes to Doors & Fittings.
