Technical Bulletin No. 9 –
Merbau
Split finished sash with untreated merbau sample
The suitability of merbau in the fabrication of architectural components, exposed to weather, can be explained through the high content of minerals and silica. The degrade, experienced in all species, whether painted or stained can be substantially reduced through the choice of the timber. Merbau has been employed by Luxbaum Windows + Doors to replace the traditional choice of hardwood, such as mahogany and teak, for the fabrication of not only new units, but replacement windows and doors as well. The water repellent characteristics of the wood, combined with its density ensure longetivity:

Density in pounds per cubic foot |
| Merbau |

| Teak |

| Honduran Mahogany |

The physical characteristics of merbau, has enabled the engineering and the fabrication of impact tested windows and doors, which have set a new standard in wood units. Merbau features extraordinary statistics:
| Specie |
Moisture Content (%) |
Bending Strength (psi) |
Modulus of elasticity (100psi) |
Masimum crushing strength (psi) |

| Honduran Mohogany |

These values have enabled us to engineer 6’ – 6” wide by 12’ – 4” high double French doors, impact resistant, without the employment in steel re-enforcement in the meeting styles.
Our search for excellence in engineering, design, fabrication, and service knows no boundaries.
