FAQs

Why is the choice of door design and ironmongery important for timber door systems?

Designers should consider the performance characteristics of different door systems. The selection of ironmongery—especially hinges and securing devices—must ensure the door system meets specified performance requirements.

What problems can occur when installing the door frame at an early construction stage?

Door frames may warp or shrink due to movement, tension, and changes in moisture content and temperature during plastering or grouting work. They may also be damaged by impact and stained by cement mortar or paint, so proper protection is needed while other trades proceed.

Which door types are covered by this guide, and what is excluded?

Due to volume constraints, the guide focuses on installing swing doors for residential projects. Fire-rated doors are not covered.
