Match the finished lining depth to the wall build-up, allowing for plasterboard and finishes. Measure at several points because masonry and stud walls may vary.
Build Square Openings for Doors, Stops and Architrave
Door Framing at MacBlair provides machined sections for forming accurate internal door linings and prepared openings. The confirmed range covers lining or framing timber that coordinates with door thickness, wall build-up, stops and decorative trim. Order against measured quantities and check the listed unit, length and pack information before work starts. timber for interior joinery provides context for the wider project.
Compare section depth, finished thickness, opening size, door handing, fire or acoustic requirements and the chosen finish. Measure the structural opening at several points and allow for packing, floor finish, clearances and the door manufacturer’s fitting dimensions. Fire doors need a tested doorset detail rather than improvised components. Where the task continues into another part of the build, skirting and architrave profiles can coordinate compatible materials.
Before work begins, confirm the wall is plumb and stable, mark the head and jamb positions, and dry-assemble the lining so joints and rebates remain square. Pack behind fixing points, check both diagonals, fix without bowing the jambs and recheck clearances before fitting architrave. Measure carefully and allow for cutting or fitting waste. Test the method on a short length or inconspicuous area when appearance matters. door hinges and fitting hardware may support the next practical stage.
Door Framing performs best when jambs are fully supported and kept square while plastering and other wet work dries. Coordinate hinges, stops, seals and ironmongery with the door specification. Prime cut ends and repair fixing marks before the decorative finish. Follow product instructions, drawings and trade guidance where structure, fire, moisture or exterior exposure affects the choice. Store remaining material as directed.
Door Framing FAQs
Use the door and lining manufacturer’s fitting dimensions, including head and jamb clearances, packing and final floor level. Nominal door size alone is not enough.
Dry-assemble it, check both diagonals and use temporary braces or wedges while fixing. Pack directly behind fixing points so screws do not pull the jambs out of line.
A fire door needs compatible, tested components and installation details, including lining, stops, seals, gaps and fixings. Follow the doorset evidence and project specification.
Fit it after the lining is secure and adjoining wall finishes are ready. Mark an even reveal, test mitres and account for the skirting junction before final fixing.
