Prior to fitting doors into the wall it is necessary to remove the tongue of the log below the door so that the metal threshold bar can sit on a flat surface and be fixed down by screwing. It is not necessary to remove the tongue from the log under windows.
Standard doors and windows are designed to open outwards; this ensures that they are watertight.
Standard windows and doors come with decorative cross bars pinned on. These are optional, so it is entirely up to you whether you leave them on or not. You may need to take them off for decorating and will need to take them off to fit double glazing.
To refit, position the vertical crossbar in the centre of the window and pin top and bottom, then fit each horizontal bar across making sure you space them equally and pin at the ends. If refitting after installing double glazing, the vertical bar only will need a small cut out to increase the step length and provide clearance for the glass beading in its new more forward position.
If you have chosen the double glazing option, the standard doors and windows will have been supplied pre-glazed with single ply glass and 14 mm double glazed sealed units will have been provided separately.
It is a straight forward task to swap the glass and can be performed at any stage really, sometimes after decorating if you are likely to splodge all over the glass!
Simply prise off the glazing bead from the outside of the door or window, ideally using a sharp chisel or a strong thin blade (that will not snap). Take care to minimise bruising of the wood.
Lift out original glass and insert the double glazed sealed unit.
Refit the beading in its new more forward position and replace the pins if necessary.
Refit the cross bars if required as described in the doors and windows section above.
