Döpfner Triple-Glazed Windows & Doors

Improving the quality of your windows, and other fenestration components, is one of the most effective ways to achieve considerable gains in your building’s energy efficiency, and reductions in those costly power demands. This is because windows are typically the weakest component of the building envelope.

“Windows can severely impact on the heating and cooling loads of a building. Up to 40% of a home’s heating energy can be lost, and up to 87% of its heat can be gained, through windows. Improving windows’ thermal performance reduces energy costs and greenhouse gas emissions”

Your Home (Australian Government)

Döpfner windows are not only highly airtight and resistant to unwanted heat gains and losses, they are also made sustainably, to an exceptional standard of quality, and of course, they look stunning too.

The window and door units arrive on your site, fully assembled, and ready to install, with triple-glazing in the aluminium-clad timber frames.

If you are unsure how the units might be installed in regards to your particular project, please don’t hesitate to contact us. You can also see a range of samples in our Fyshwick showroom.

Technical Specifications

Poor windows make it hard to achieve a balanced indoor climate, as they waste valuable heating and cooling energy.

Modern glazing technology achieves very high energy efficiency values which, until only recently, seemed impossible.

Döpfner uses high-performance triple-glazing elements, which are double argon filled, in order to meet requirements in thermal performance (U-value), air sealing, solar control (SHGC) and acoustics (Rw, the weighted sound reduction index, and not to be confused with thermal resistance, R).

Timber Types

Döpfner windows feature a solid timber construction, made from a wide selection of European timbers, including Spruce, Pine, Larch and Oak.

All Döpfner timber is sourced exclusively from renewable plantations in Central Europe with Forest Stewardship Council (FSC) certification.

“Many resources on our planet are limited, some are almost depleted: timber is not one of them. It grows in continuous cycles, and acts as a carbon sink, as well as an oxygen generator, while it is growing.”

Döpfner (GER)

Triple Nano-Coating

All timber surfaces are coated with three specially formulated protective layers:

• Base layer: penetrates the timber and protects against rot and discolouration.
• Intermediate layer: builds a transparent UV-protective film which does not obscure the natural timber texture.
• Outer layer: serves as a weather-proof surface shield.

This elaborate coating combines highly transparent natural timber colours with unmatched durability and low-maintenance. In addition to the natural timber finishes, Döpfner offers timber stains and oils, as well as a wide range of RAL colours for a painted finish.

Cladding Types

Aluminium cladding frames on the outside of your window act as the perfect durable shield, which can withstand even the most extreme weather conditions.

The aluminium frames are fully welded and polished to perfection before the final powder coating is applied. This elaborate process ensures a perfectly seamless, high-quality optical finish that maximises longevity.

There are a huge variety of aluminium contours available to suit any project, and new profiles are constantly being added to Döpfner’s catalogue all the time.

RAL Colours

Döpfner windows and doors offer a wide variety of surface types and colours, which are based on the European RAL colour standard.

Profile Types

Döpfner windows offer a range of timber profile contours, which allow you to select the perfect look and feel for your home.

There are currently four timber profile contours (Types 1 – 4), along with variable window frame depths of 68mm, 78mm and 88mm.

Tilt & Turn (Windows & Doors)

Tilt & Turn
Turn Only
Tilt Only

Relatively unknown in the Australian market, tilt & turn functionality has become very popular in Europe. The window and door units can pivot on vertical hinges to turn fully open (as you would expect from a standard window or door with ~ 180 degrees range). Windows and doors with hidden hinges that open >135° may squeak slightly when opened beyond 135°. This is normal behaviour and is not covered by warranty.

The entire top edge of the unit can also tilt inwards (~ 20 degrees from vertical), as the bottom edge remains securely anchored to the frame, maintaining your building’s security.The tilt function provides natural ventilation with the external environment, whilst allowing light rain to also run down the window and drain through to the external environment.

The standard units have a small step (20mm) at the bottom edge of the frame, however they can also be ordered with a MACO sill, which sits flush with the floor level (wheelchair accessible). They are also available in French style configurations (double doors).
