Overview
What makes the MB-79N CSF Casement
stand out.
The MB-79N CSF (Casement Slim Frame) is Aluprof's purpose-built outward-opening casement for markets that prefer push-out operation. Built on the MB-79N thermal platform with 70/79 mm frame/sash depth, the CSF uses hybrid hinges rated to 80 kg sash weight and features an ultra-slim outer frame visible from outside. Multi-point espagnolette locking and interior screen integration make it a natural fit for US residential projects where casement windows are the norm.
Key Highlights
- Outward-opening casement - US-familiar push-out operation
- Slim outer frame: minimal visible aluminum from exterior
- 80 kg hybrid hinge for heavy triple-glazed sashes
- Multi-point espagnolette locking for superior seal compression
- Interior screen integration without compromising operation
- E, ST, SI thermal variants matching the MB-79N family
Ideal For
US residential projects where casement operation is preferred, builders transitioning from domestic to European aluminum, and cold-climate homes requiring outswing with screen compatibility. The slim exterior frame suits modern facades.
Consider an Alternative When
If you prefer tilt & turn operation (European-style inswing), the standard MB-79N offers better air and water tightness. The Reynaers SlimLine 68 is a premium-brand alternative with slimmer sightlines.
