Description

The MB-77HS numbers among SBW ’s top systems in terms of performance and meets all the requirements for its product group. In terms of thermal insulation, it has two different variants: the ST and the HI. The profiles used in this product make it possible to fabricate exclusive, large-scale
doors with double or triple glazing units, while the materials and technical solutions used help to achieve a high degree of thermal and noise protection. Thanks to its specifications, the MB-77HS system is ideal for single-family houses, comfortable apartments and hotels. The MB-77HSB was developed to meet the needs of the Belgian market.

The slender

The slender, durable profile makes it possible to build a low-threshold door with a leaf weight of up to 600 kg, a height of up to 3.2 m, and a width of up to 3.3 m.

The frames

 Single- or double-glazed uA wide range of infills, includingnits, along with thermal breaks and a selection of accessories and insulating inserts, makes it possible to achieve excellent thermal and acoustic parameters.

The closed shape of the glazing beads and the anti-tamper details make it possible to obtain increased burglary resistant properties without changing the fundamental construction elements of the door.

The glazing beads come in three versions: Standard (rectangular), Prestige (rounded), and Style (diamond-shaped).

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.
