Filled with argon gas and finished with Low-E coatings, these units keep heat out, block UV radiation, lower energy costs, and add acoustic insulation — keeping interiors cooler and protecting your furnishings for years. Read more ->
German Tilt & Turn Windows – Smart, Practical, Proven
Typically WOHNRAUM windows open inwards using the German Tilt & Turn system — one window, two opening modes.

Better Soundproofing
Up to 95% noise reduction.
Enjoy a quiet home by significantly reducing traffic, street, and neighborhood noise. Ideal for busy urban areas, apartments, and homes near main roads, so you can relax, focus, and sleep better.
Superior Security
Stronger frames and Hardware
UPVC windows are built with reinforced frames and multi-point locking systems for improved protection. This makes your home safer and gives you greater peace of mind for your family and property.
Termite and Rot-Proof
No rot, no rust, no decay
Unlike wood, UPVC does not attract termites, rot, or corrode in humid tropical climates. This means a longer lifespan, less maintenance, and a window that stays in good condition for decades.
Highly Energy Efficient
Lower cooling costs — more comfort
UPVC windows with insulated glazing provide excellent insulation that helps keep heat outside and cool air inside. This reduces the need for air conditioning and can help lower your monthly electricity bills.
