Installation instructions for door frames

Using ready made door systems has considerably simplified the manufacture and installation of conventional doors which, until now, have been rather expensive and complicated.

The system consists of a ready to install door frame and architrave and a ready to hang door leaf. The frame and architrave are assembled from individual sections using supplied accessories and inserted in the wall opening; the door leaf is hung and the new door unit is ready.

The installation of the door frame is uncomplicated, as demonstrated by the illustrations:

Stage 1 Diagram

1. Insert the metal cross dowels into the pre-drilled holes at the corner joints of the frame uprights.

Stage 2 Diagram

2. Insert the collars into the pre -drilled holes of the cross section of the architrave.

Stage 3 Diagram

3. Apply white adhesive to butt joint ends and mitred edges.

Stage 4 Diagram

4. Join the frame sections with flathead screws and architrave sections with set screws, starting with the architrave. Any surplus adhesive must be removed immediately. Let the adhesive cure before proceeding further.

Stage 5 Diagram

5. Then tighten up the screw for the hinged frame section using the 4mm Allen key. Cut door seal to suit avoiding any stretching.

Stage 6 Diagram

6. Insert the assembled frame into the wall opening. If necessary adjustments can be made for any irregularities in the wall opening. The hinge side of the frame must be plumb and fixed at the top.

Stage 7 Diagram

7. Hang door leaf, check that it operates correctly and adjust, if necessary. The lower gap between door and floor may be modified by adjusting the frame or by shortening the door leaf. (See 12) Line up the lock plate side of the frame with the door leaf and fix.

Stage 8 Diagram

8. Pack cavities between wall and frame at hinge and lock plate level with timber packing pieces, if required. To ensure an accurate fit, clamp three braces between the two upright frame sections.

Stage 9 Diagram

9. Tip: To avoid overspill onto the frame from the expanding foam, insert cardboard strips in the groove of the architrave prior to application.

Stage 10 Diagram

10. Apply double-compound foam to the cavities at the height of the braces and at least 30% of the cavity area.

Stage 11 Diagram

11. Insert the already assembled architrave into the groove of the installed frame. Start at top corner and gradually insert the architrave parallel to the wall. The adjustable architrave evens out any variations in the wall thickness.

Stage 12 Diagram

12. For hard floors (e.g. tiles, parquet flooring) the bottom of the frame should be sealed to prevent penetration of water. The frame can also be raised using a spacer strip if necessary.
