Louvre windows at their best: FIEGER louvre windows

Our windows in the FLW range are our most popular products. Our industry leading double and triple-glazed windows provide all the advantages that louvre windows can offer.
FLM are uninsulated, single glazed windows. With an architectural, sleek and frameless design, they offer controllable ventilation with a touch of elegance, suitable for unheated rooms, winter gardens or as a second skin façade.
FLL are aluminium skinned insulated louvres, suitable for internal or external applications.

FDS, our special design product, a bespoke window package, ready to turn your ideas into reality.
All FIEGER louvre windows are available with manual, electric and pneumatic drives. With custom fitting adapter extrusions, they can also be individually customised for installation into any system. All glazed windows can be ordered with float, ESG or VSG glass or any combination thereof.
