Safe installations in plasterboard15. July 2019
Drywall has become indispensable to interior construction. Special anchors are required for installations in this type of construction material. Below we will show you how to save time and money with fixings in plasterboard while ensuring a secure hold.
Drywall is particularly popular in interior construction. Thanks to its various sizes and weights it is used for non-loadbearing interior walls in addition to wall, roof and ceiling panels. The panels can easily be processed and resized using a utility knife before being broken apart. It might be worth purchasing a special plasterboard saw for users who regularly work with this construction material. New rooms, walk-in wardrobes and the like are thereby created in no time. Mounting pictures, smoke detectors and other objects in drywall requires special plasterboard anchors however, because this construction material is not particularly strong.
The fischer DUOBLADE is a plasterboard variant that saves both time and costs. Plasterboard anchors made of plastic usually require a special setting tool in order to insert the anchor into the panel. The setting tool is inserted in the cordless screwdriver instead of a bit. You needn’t worry about that with the fischer DUOBLADE. Thanks to its metal drilling tip and sharp thread it cuts into the drywall perfectly. A common cross-shaped tool mount (PZ2) provides a perfect hold in the cordless screwdriver, so there is no need for pre-drilling with these anchors. This product is ideal for situations where there is little space behind the construction material. The fischer DUOTEC is another plastic plasterboard anchor and is the best option for slightly higher loads.
Which wall plug for fixings in plasterboard?
The hollow cavity fixing made of metal is an alternative product to the plastic fixing and also provides an optimum form lock in the construction material. The metal cavity fixing HM folds open like an umbrella and engages behind the panel. The anchor works according to the following principle: the more surface lies behind the panel, the more load the anchor is able to carry. Drywall is not particularly strong however and can therefore quickly break. Pliers are required in order to place the cavity fixing HM. An expanding mechanism takes care of this when it comes to the cavity fixing HM.
Damage-free installation with a detection device
Timber frame walls are commonly used as drywall substructures. Power supply lines and water pipes can often be located behind the plasterboard panel. If you’re unsure where exactly these supply lines are located, then you could end up with water damages or short circuits in the worst case. You should therefore use a detection device which can be found in specialist stores as well as discount supermarkets. The device is simply placed on the plasterboard and the sensor will search for any cables located behind it. It is best to make a small mark in those areas where the device detects any cables. This area should be avoided when it comes to drilling.
If you’re carrying out a renovation or you’re constructing something new then regularly take pictures of the open walls. Store the images on your laptop or to a cloud. This will allow you to see where any cables are months or years down the line, which will help you prevent accidentally hitting a cable when drilling.
How much load can a plasterboard anchor take?
First you should make sure that your anchor really is suitable for drywall. Once you have found the right anchor, you should also make sure it is suitable for your application. You should consult and expert if you want to mount heavy loads such as kitchen cabinets and other applications that need to be securely installed. A professional solution is required for secure installations in this construction material. Information for lighter loads can be found on the packaging. The specified load values can only be achieved if the object has been installed correctly. High-quality anchors tend to have a safety margin on the load. The specified load should never be overstepped when purchasing cheaper anchor variants. A high-quality nylon anchor allows a little more leeway, but the manufacturer can only guarantee the specified load. By the way, double layered drywall panels are able to hold more weight than single layers.
If there is a hollow space behind the drywall then it can be used in order to engage behind the panels. Products such as the HM, KD or fischer DUOTEC will allow you to reach higher load values than the form lock in the panel alone.
