Description

MB-SLIMLINE – Slim Aluminium Window System with Thermal Break

The MB-SLIMLINE is a high-performance, thermally broken window system designed for modern and renovation projects that demand both sleek aesthetics and excellent insulation.

Ideal for external use, this system supports a wide range of inward-opening window types—including side-hung, tilt-and-turn, hopper, and fixed windows—while delivering outstanding thermal insulation, airtightness, water resistance, and soundproofing.

With ultra-slim aluminium profiles visible from the outside, MB-SLIMLINE offers two design options:

  • Standard version with visible sash lines

  • SG version with concealed sashes for a seamless, uniform appearance between fixed and opening units

This system is also a perfect choice for replacing traditional steel-framed windows, preserving the slim, industrial-style look while significantly improving thermal efficiency and overall performance.

We have used SBW on several occasions over the years and always found their services very good, hence I’m a repeat customer. I’ve had bifold and sliding patio doors, front door, other exterior doors and replacement double glazing windows. Quality products, great customer service and aftercare.

Was very impressed both by the service and the product. After a bad experience with a previous window company, which you could feel the draft coming through after one month of instalation, I was skeptical to try different company. I am thrilled I found SBW GROUP. I had my windows done in April 2024 and the quality is above my expectations. The installation team was very organised, professional and considerate and we are very pleased with the results. Highly recommend them.
