Description

The SBW 76 window system represents the new generation of modern uPVC windows, combining contemporary design, versatility, and enhanced energy efficiency. Built around a 76 mm deep profile with 6 internal chambers and three sealing gaskets, the system is suitable for both new-build projects and renovation works.

The window features a central uPVC gasket integrated into the sash profile, acting as a true safety barrier. This element increases structural rigidity, improves airtightness, and enhances burglar resistance. With its minimalist design, clean surfaces, and straight lines, SBW 76 integrates seamlessly into modern architectural styles.”

Advantages

High Energy Efficiency

The SBW 76 system features a 76 mm, 6-chamber profile with three sealing gaskets for excellent thermal performance. It achieves Uw values of up to 0.87 W/m²K, helping maintain comfort and reduce energy costs year-round.

Advanced Sealing

An integrated central gasket and safety wall improve airtightness and structural stability. This creates strong protection against drafts, water ingress, and external noise.

Sound Insulation

Provides acoustic insulation of up to 44 dB for a quieter indoor environment. Ideal for urban homes or high-traffic areas.

Energy Savings

Efficient insulation minimises heat loss in winter and overheating in summer. This results in lower energy consumption and reduced utility bills.

Modern Design

Clean lines and balanced proportions suit contemporary architecture. Available in white with black gaskets and multiple colour finishes for full customisation.

Flexible Glazing Options

Supports glazing thicknesses of 24–50 mm for fixed sashes and 26–52 mm for opening sashes. Compatible with modern double and triple glazing units.

Weather Resistance

Engineered to withstand strong winds and heavy rain. Tested to Air Class 4, Wind Class C4, and Watertightness Class 8A.

Enhanced Security

Can be configured up to RC2 security class for reliable burglar resistance. Reinforced profiles and secure hardware provide added protection

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.
