ALUMINIUM WINDOWS

We believe superior manufacturing elevates our product above nearly all other aluminium products. And, feel that when you need the best, Bergmann will be your premier thought. Bergmann Aluminium products will meet – and exceed – demands of multiple applications. Everything from heavy duty and light commercial new builds, to large-scale refurbishment projects and residential new builds can be supplied.

Designed for light and airy interiors, this system is available as casement, fixed or French windows.

A range of outer frame sizes accommodate different plaster lines and window reveals – ensuring a perfect, neat finish. Slim sashes allow more light into any home, expanding the sense of space.

These game-changing benefits feature in all our BERGMANN aluminium products:

Windows, Doors, Bifold Doors and Patio Doors

  • • Most thermally efficient

    • Full depth Eurogroove

    • Thermlock® multi-chamber thermal break

    • 7 colours, dual colour, bespoke colour

    • Patented corner construction method

  • A full-depth Eurogroove enables the latest high security, multipoint locking mechanisms.

    Additional features like unique hinge protectors also help create exceptional levels of security. The clever integrated design ensures all lock-cases are fully enclosed, means the glazing or beading areas of the window/door aren’t affected – which weakens the frame’s integrity.

  • Hidden inside all BERGMANN products is an innovative Thermlock® multi-chamber thermal design. Insulating chambers act as a thermal break and work with high-performance glazing creating class-leading thermal performance, superior to traditional polyamide.

Thermlock® technology

Hidden inside all BERGMANN products is an innovative Thermlock® multi-chamber thermal design. Insulating chambers act as a thermal break and work with high-performance glazing creating class-leading thermal performance, superior to traditional polyamide.

Thermal transmittance, or U-value, measures the rate of transfer of heat. The better insulated a window is the lower the U-value

Every window tuned to perfection

This patented construction method using threaded rods to bind corners together tightly – eliminating misaligned corner issues that can occur on ordinary aluminium frames.

Co-extruded weather-seals on clip-together sills and other ancillaries also means there’s minimal need for silicone sealing, saving time, money and creating more consistently reliable weatherproof installations.

Dual colours as standard

Colour is as important on the inside as much as the outside. That’s why we offer any dual colour options on all BERGMANN products.

Bespoke colours are available.

Please note: Due to variables in screen colour displays, these colours are intended to be used as a guide only.
