Aluminum casement windows are a natural fit for low-rise homes — villas, townhouses, duplexes, and single-family houses. They hang on side hinges and open outward, which means a full-width opening for fresh air without a bulky frame cutting into the view. For a two- or three-storey home, a well-chosen casement window does more than frame the garden: it controls ventilation, keeps out noise and weather, and stays easy to operate for decades.
Casement windows have been a staple of residential building for good reason. On a low-rise house, a few things matter more than anywhere else, and casements happen to be strong in all of them:
Ground-floor windows are an easy target, so look for multi-point locking and anti-pry lock points rather than a single central latch. ALPES casement windows use ROTO transmission boxes and anti-pry lock points as standard, with 360° locking distribution on the premium AW90 tilt-and-turn series — the kind of hardware you want on a window someone could reach from outside.
In most climates, a thermal break profile is worth the investment. The ALPES C120 outward-opening system window reaches a thermal K-value of 1.6, and the C116 sits at 1.7 — comfortable numbers for a well-insulated family home. The insulation strips are PA66GF25 multi-chamber profiles, the same material family used across the range.
Triple sealing strips with welded corners block wind, rain, and street noise. On a low-rise home near a road, that is the difference between a quiet bedroom and a noisy one. The C113 and C116 both use a full triple-sealing design, and the C120 adds complete corner sealing with injection-molded structural adhesive.
Low-rise homes usually want screens on windows that open. ALPES casement windows come with integrated stainless steel mesh as standard — 40# black S/S mesh, with high-definition anti-PM2.5 mesh available — so you get ventilation and insect protection in one unit, with no separate screen frame to maintain.
Casement windows are made to measure, so they work in kitchens, bedrooms, living rooms, and bathrooms alike. Standard configurations can be adapted to the opening, and a custom casement window can be built for larger or unusual openings without compromising the seal or the hardware.
C120 Outward Opening System Window — the flagship
1.8–2.0mm 6060-T66 profiles, thermal K-value 1.6, and an integrated window-and-mesh design with instant mode switching. ROTO transmission box, anti-pry lock points, fall-rope safety mechanism, and roller locking device. A solid all-rounder for living rooms and master bedrooms.
C113 Outward-Open Window
1.8–2.0mm profiles with a full glue-injection process and triple sealing defense. CMECH hardware — a German Red Dot Design Award winner, tested to 30,000 cycles. A dependable choice for bedrooms and studies.
C116 Outward-Open Window
A slim 28mm frame with a 22mm medium mullion that maximizes the view. Thermal K-value 1.7, triple sealing with seamless welded corners, easy flat-channel drainage, and an optional German Wehag hardware upgrade. Great for rooms where you want the window to disappear into the wall.
All three use 6060-T66 aluminum profiles with PA66GF25 insulation strips, and come in standard colors including Ice Cream White, Aurora Gray, Starry Sky Gray, and Brown Coffee — with custom color matching available. You can browse the full series on the casement window category page.
There is no single "right" casement window size — it depends on the opening and the room. As a rule of thumb, a single casement panel suits openings up to about 800mm wide; wider openings are usually handled with two panels or a panel plus a fixed light. Height is typically driven by the room and the floor-to-ceiling design. The ALPES team can confirm what works for your opening and recommend the right series for each room.
Are aluminum casement windows suitable for low-rise homes?
Yes. They are among the most common window types for villas, townhouses, and single-family houses, offering strong sealing, good ventilation, and low maintenance.
Are casement windows secure on the ground floor?
Yes, when they use multi-point locking and anti-pry hardware. ALPES casement windows come with ROTO transmission boxes and anti-pry lock points as standard.
Do the windows come with insect screens?
Yes. ALPES casement windows include integrated stainless steel mesh as standard, with high-definition anti-PM2.5 mesh as an option.
Can I get custom sizes?
Yes. Casement windows are made to measure, and custom sizes are available for non-standard openings.
How do casement windows compare to sliding windows?
Casements generally seal better and offer a larger opening for ventilation, while sliding windows take up no swing space. For low-rise homes, many owners choose casements for bedrooms and living areas and sliders for balconies and patios.
For a low-rise home, aluminum casement windows deliver the combination that matters most: real ventilation, a tight seal, solid security, and a clean look that does not age.
