selecting the door design,designers shouldtake into consideration the performance characteristics of the various door systems.Inaddition,the choice of ironmongeries,especially the hinges and securing devices,is importantto ensure that the selected door system meets the specified performance requirements.  \nThe timber door is one of the most common and more problematic areas in building works.Defect complaint on timber door is one of the main complaints especially during handingover.Some of the common complaints from owners are mentioned in Chapter 9.  \nThis guide is to share with the industry the good practices to achieve quality timber doorsthrough proper door design,handling&storage,preparatory works,installation and protectionworks.It adopts the quality standards set out in CONQUAS 21 and includes the CONQUASquality assessment criteria in the recommended inspection checklists.  \nDue to volume constraint,this guide focuses on the installation of swing doors for residentialprojects.Fire-rated doors are not covered.  \n# 2.Design\n\nThere is a wide range of timber doors and ironmongeries available in the market.This guide focuses only on thecommonly used products.  \n2.1.TYPES OF TIMBER DOORS  \nTable 2.1 shows the types of timber doors commonly used in local residential projects.  \nTable 2.1 Types of timber doors  \nTypes of timber doorsDescription and uses  \n## 1.Swing door\n\n### 1.1.Traditional system\n\nWALL  \nDOOR PANELMAIN FRAMEARCHITRAVE  \n·Installation of door frame is carried out as the wall is being erected.  \n·This system is fast being replaced by the sub-frame system as installingthe door frame at early stage of construction faces the followingproblems:  \no Door frame may warp or shrink due to movement,tension,as wellas change in moisture content and temperature during plasteringor grouting work  \no Door frame may be damaged/dented by impact of heavy objectso Door frame may be stained by cement mortar or paint  \n·Proper protection of the door frame is needed while other trades arein progress.  \n### Types of timber doors\n\n1.2.Sub-frame system  \n1.3.Rebated and lift-up door system  \nDescription and uses  \nDOOR PANELMAIN FRAMEARCHITRAVESUBFRAME  \n·Consists of a sub-frame and a main frame.  \n·The sub-frame is installed at the early stage of construction.Theinstallation of the main frame will only commence after the completionof other internal trades.  \n·Sub-frame is usually fabricated with a smaller width (about 10mm)than the main frame to allow adjustment for any misalignment.  \n● There are two methods of installing the sub-frame:o before wallerection;ando after wall erection  \nInstalling the sub-frame after wall erection is preferred as no studdingof door sub-frame is needed.  \n● The advantages of sub-frame system are:  \no Prevent damages to the main frame and save cost and time fromundesirable abortive works  \no No staining of door frame by cement mortar and paint  \no The main frame is less likely to be subjected to warpage orshrinkage due to differential movement,tension or change inmoisture content and temperature during plastering or groutingwork  \nLIFT-UP HINGEDOOR
