Effective insect protection: weatherproof, wear-resistant and fireproof

Düpmann insect protection products give you the protection you need whilst visibly unnoticeable. They allow you to ventilate your rooms throughout the day without the need for  harmful sprays. With this, you can still enjoy the summer and winter breeze without having to deal with mosquitoes, flies, spiders, or wasps.

Screen the insects away…

The materials we use are of robust and professional quality, fireproof, wear-and-tear free, and have a high level of resistance  against all weathers. We have  a variety of choices available: e.g. tenter frames, curtains, ventiduct guards, hinged doors and windows, vertical and standard sliding doors. You also have the choice to select the color frames individually. For an unhindered view, choose our silver grey gauze.

The silk-like gauze screens offer additional uncomplicated protection against seasonal pollen from entering your living space.

For those with pets, consider our Pet screens that cannot be easily destroyed by your playful pets.

Tenter Frames

Tenter Frames

Tenter frames are extremely functional as they can be adjusted to fit any given window shape and size. In addition, they are a low-cost alternative. Tenter frames are easy to assemble even if there is just a little space available. They can be installed in windows made of aluminum, wood, or plastics and do not derail existing shutters.

Easy removing of the tenter frames is made possible due to existing hangers.

This feature prevents any interference during window cleaning. Nearly every window form can be equipped with a suitable tenter frame. Shapes such as triangles, trapezes round arches, or chamfers are possible.

Revolving Doors

Revolving Doors

A revolving door is an optimal solution for balcony doors or patio entries. This type of insect protection can be used on constructions with limited space available.

Düpmann has developed an integrated handle especially for such situations, allowing you to use existing elements like shutters without any detractions. In addition, the integrated handle serves to further stabilize the door frame. Damages are avoided by using a protective footplate at the bottom of the screen. Built-in magnet strips are used as closing devices, increasing the screen's ease of usage.

The construction of each revolving door or window is based on the given geometry of the architectural site.

Insect protection sliding elements are usually used to bridge large ranges, such as balconies, patios, winter or summer gardens, and balcony enclosures. For the most part, one-element sliding doors are delivered. However multi-wing elements are also available. The single frames have wear-free rollers, therefore making the whole construction maintenance-free. A newly designed handle offers convenient handling and in addition, stabilizes the whole construction frame.

A further solution has been developed by Düpmann Aluminium Systeme GmbH. Asides from our standard element a suspended door is also available to customers. This suspended door is fixed at the upper track of the construction thus eliminating a potential stumbling block at the bottom. This barrier-free solution is a significant surplus for you and avoids potential risks.
