3.2 Safety In Use : Additional Requirements for Doors
Virtually any type of door can be produced in PVC-U , such as single hinged , double doors , inward or outward opening , in-line sliding , folding & sliding , tilt & slide and lift & slide . When choosing a particular type of door , consideration should be given , for instance to the following ( including the requirements for windows given in the previous section ) : -
• Access to buildings and the requirements of low thresholds and size of openings for wheelchair access .
• Safety in case of fire . It is important to ensure that means of escape in case of fire are provided . EN 14351- 1:2006 + A1:2010 also specifies that fitting of any emergency exit / panic hardware for a locked door on an escape route must comply with clause 4.10 .
• The provision of additional security devices such as spyholes and chains need to be specified and agreed .
4.0 Handling and Storage
When transporting glazed or unglazed frames , they should be firmly secured in an upright position on clean resilient packing . This will help prevent scratching of the surface of the profile .
Frames stored on site should be treated in the same way and should be carried securely and placed in position without heavy impact , do not rest , lower or drop frames on corners or edges as it may result in permanent damage .
Windows that are delivered pre-glazed should have the glazing packed to ensure correct operation and to minimise distortion and breakage . Windows which have had the frames and glazing delivered separately should be packed in accordance with the recommendations and the latest version of BS 6262 and BS 8213-4 .
PVC-U has a high resistance to weather , corrosion , and most materials found on building sites . However , as it is possible to deliver PVC-U frames , including glass to the installer in a “ completely finished ” condition , care taken in transport , storage and handling will prove beneficial , thus ensuring a good installed appearance and customer satisfaction .
