Why Bluminium

Specified by architects.
Tested to standard.

Every figure on this page is what we actually measure our own work against — not marketing rounding. Ask for the full test reports on any project.

Eight things every order is measured against.

Before a single frame leaves the factory floor.

01

Precision Fabrication

Every frame is cut and welded to a tolerance of under 1mm using CNC-calibrated machinery.

± 0.8mm
02

Thermal Performance

Polyamide thermal breaks reduce heat transfer, keeping interiors stable year-round.

U ≤ 2.1
03

Finish Durability

Marine-grade powder coating holds colour and resists corrosion in coastal climates.

15YR WARR.
04

Security Glazing

Multi-point locking and laminated glass options meet SANS security requirements.

SANS 613
05

Water Resistance

Drainage-channel profiles and EPDM seals tested against wind-driven rain penetration.

CLASS 9A
06

Wind Load Rating

Frame and glazing combinations engineered and tested for coastal wind exposure.

≤ 2.6 kPa
07

Acoustic Performance

Laminated glazing options reduce external noise transfer for road- or coast-facing openings.

Rw 32dB
08

Air Infiltration

Compression seals on every opening sash minimise draught and energy loss.

CLASS 4

Tested against the standards that matter.

Every system is manufactured and installed in line with recognised South African and international building standards.

SANS 613

Burglar bars and security gates — security glazing & locking compliance

SANS 10400-XA

Energy usage in buildings — thermal performance requirements

SANS 1253

Aluminium windows — dimensional & performance standard

ISO 9001

Quality management system — factory fabrication process
