Custom insect screens
High-quality insect protection from MHZ
What is an insect screen system?
MHZ custom insect screens are fitted to secure windows, doors and light wells to provide lasting, almost invisible, protection from mosquitoes, wasps, bees, flies, beetles and spiders, improving the quality of life in your home.
The large selection of insect screens and special meshes from Neher Technology meets the highest demands. The Polltec® TFP mesh, for example, will keep insects and pollen out of your home and create a pleasant atmosphere.


During the summer months especially, mosquitoes, flies, wasps and other insects can often stop us from sleeping. Our custom-made insect screens for windows and doors, not to mention our light well covers, protect your interiors from annoying insects and small animals. Custom-made tensioning frames, swing frames and side-hinged frames for windows and doors, sliding systems, pleated doors and roller blinds can be fitted in just a few simple steps.
The stable aluminium profiles blend in seamlessly with the overall look of your home and guarantee that windows, doors and roller shutters can be operated unhindered. The insect screens and insect screen roller blinds can be installed flexibly and are easy to clean. At the same time, these custom-made products fulfil high security standards.

Areas of application for insect protection
Insect protection and insect screens for windows and skylights
A tensioning frame is impressively quick and easy to install. It is lightweight and fits into the window frame with very little effort. Our range of MHZ insect screens includes over 150 different versions that come with a tensioning frame. And, of course, we have solutions ready for you if your installation situation is a bit more challenging than usual too.
A tensioning frame is inserted quickly and easily, plus it can be removed just as rapidly and without any fuss if you want to clean the window, for example.
One thing that it is important to know... With the right tensioning frame, windows and roller shutters can always be operated unhindered.


Side-hinged frames and swing frames can open in both directions and are especially well suited to windows that are opened and closed frequently. Side-hinged frames open in one direction, either inwards or outwards. Modern swing frames, on the other hand, open in both directions. The frame is fitted into the window frame.
Our MHZ insect screen roller blind is attached to the inside or outside of the window (between the window and the roller shutter). Just like a conventional roller blind, it can be opened and closed really easily to water plants or air out beds. To ensure completely reliable protection from insects, the side guides on this custom-made product are fitted with thick brushes.
One really practical aspect is that the insect screen roller blind can be integrated into the window, whether it be on the building front or a skylight in the roof.
Insect protection and insect screens for doors
Mosquitoes, wasps, beetles et al do not stop at balcony doors, patio doors or house doors. Custom insect screens for doors provide well-thought-out solutions for every room. The frame is fitted into the window frame for these products too.
Insect protection and light well covers for basements and underground garages

Our light well covers are:
- Weather-resistant and rust-proof – thanks to corrosion-resistant materials
- Hard-wearing and non-slip
- Able to let in light and air
- Optional: safe to drive on thanks to robust expanded aluminium

Mesh types for insect screens

The mesh is at the heart of your insect screen. Different insect screen meshes are needed, depending on the application in question. After all, it is only with the right mesh that your insect screen roller blind or custom insect screen will be able to meet all the demands placed on it. We offer an enormous variety of meshes for your specific needs and applications.
Their range of different properties, from transparency and breathability, weather resistance and tear resistance, to protection from insects, electrical smog and pollen, ensures that you will achieve a high degree of comfort.
The tried-and-tested standard mesh for insect screens made of plastic-coated fibreglass. It has great tensile strength and weather resistance.
With up to 140% higher breathability than our standard mesh, the Transpatec® mesh creates a nice atmosphere. It is self-cleaning and stays practically invisible all year round. It also has even better tensile strength and weather resistance than fibreglass mesh.
The pollen protection mesh protects from clinically relevant pollen and, thanks to its minimal mesh width, against tiny little insects too. Yet it also lets in more light and air than standard fibreglass mesh.
The electrical smog protective mesh protects against insects and high-frequency electromagnetic radiation emitted by mobile phone masts, for example.
Reliable protection from leaves and small animals, while being very hard-wearing and easy to clean.
Cat-proof insect screen mesh with extremely good tensile strength thanks to 7-fold reinforcement.
The stable and unobtrusive alternative for special applications.
Fabric for insect screens – your questions, our answers
Over time, dust and pollen can accumulate on the insect screen mesh. We therefore recommend cleaning it occasionally. Take particular care to do this gently, using very little pressure. The mesh can be cleaned either with a damp microfibre cloth or a vacuum cleaner with a upholstery nozzle. Profiles and fittings can be wiped with a damp microfibre cloth.
High-quality insect screens are designed to ensure both optimal air circulation and maximum light transmission. Special types of fabric offer virtually invisible protection with excellent visibility and air permeability.
Yes, there are special pollen screens for allergy sufferers that effectively keep out not only insects but also pollen. Pollen screens for allergy sufferers have very narrow meshes and effectively keep out not only annoying insects but also a wide variety of pollen.
Damaged fabric can be replaced. Minor repairs can sometimes be carried out on site. Otherwise, the specialist partner will take care of dismantling, delivery to the factory and reassembly. If you do not know the original specialist partner or if you encounter any other problems, please feel free to contact us. We will help you find a specialist dealer or you can use our specialist dealer search.
For households with pets, MHZ offers particularly robust insect screens that are scratch and tear resistant. In addition, pet flaps in various sizes can be installed in doors, allowing cats and medium-sized dogs to come and go easily without affecting the insect screen.
There are special requirements for restaurants and catering establishments. Our hygienic stainless steel or aluminium mesh is ideal for this purpose and can even be cleaned with a high-pressure cleaner.

Can I install insect screens myself, or should I hire a professional?
While DIY solutions are available, custom-made insect screens installed by professionals offer the best protection and longest service life. Professional installation ensures that the screens fit perfectly and function optimally. Specialist companies can also offer customised solutions for specific requirements.
Are MHZ insect repellent products also effective against tiger mosquitoes?
Yes, our insect screens also keep tiger mosquitoes out of your home.
Are there insect screen solutions that can be installed without drilling?
Yes, MHZ tensioning frames can be installed without drilling. They are clamped in place and are particularly suitable for rented apartments or listed buildings where structural alterations are undesirable. Furthermore, doors, for example, can also be installed without drilling using modern mounting adhesive tapes. This prevents thermal coupling.
Can insect screens be fitted to all types of windows?
There are customised insect screen solutions for almost all window types, including roof windows. Our MHZ specialist dealers can assess the conditions on site and recommend the right solution.
How do custom-made insect screens differ from DIY store products?
Custom-made insect screens are individually tailored to the specific dimensions and requirements of your window or door. They offer a perfect fit, higher material quality and often a longer service life. DIY store products, on the other hand, are standardised solutions that do not always fit perfectly and may wear out more quickly.
What if the owner insists on a specific colour?
Our MHZ insect screen systems are available in the most common standard colours. However, if these colours do not suit your requirements, MHZ can supply fly screens in special colours according to RAL, IGP or NCS.
Our numerous local specialist dealers offer you an all-round service - from measuring at your home to installing the custom-made fly screen. Find a dealer near you now.
