Internal Door Installation for London Victorian Terraces: Period Profiles, FD30S Fire Doors, and Door Furniture

THE CORRECT DOOR PROFILE CHOICE IS FUNDAMENTAL TO MAINTAINING THE PERIOD AUTHENTICITY AND CHARACTER OF A LONDON VICTORIAN TERRACE RENOVATION — AND THE WRONG PROFILE (PARTICULARLY A MODERN FLAT-PANEL OR FLUSH DOOR) CAN SIGNIFICANTLY DETRACT FROM THE PROPERTY'S CHARACTER AND VALUE.

4-PANEL DOOR (THE MOST HISTORICALLY AUTHENTIC DOOR FOR A LONDON VICTORIAN TERRACE — GROUND FLOOR AND FIRST FLOOR ROOMS): THE 4-PANEL DOOR (TWO LARGE LOWER PANELS PLUS TWO SMALLER UPPER PANELS — ALL SEPARATED BY SOLID STILES AND RAILS) IS THE DOMINANT PROFILE FOUND IN LONDON VICTORIAN TERRACE INTERIORS OF THE 1860S-1900S. PROPORTIONS: THE UPPER PANELS ARE TYPICALLY TALLER RELATIVE TO THEIR WIDTH THAN THE LOWER PANELS — THE CLASSIC VICTORIAN 4-PANEL ARRANGEMENT HAS UPPER PANELS OF APPROXIMATELY 300MM HEIGHT AND LOWER PANELS OF APPROXIMATELY 700-800MM HEIGHT (IN A STANDARD 1981X686MM DOOR). AVAILABLE FROM: LPD DOORS (LPD VICTORIAN 4-PANEL — 1981X838MM AND 1981X762MM — SOLID SOFTWOOD — PRIMED FOR PAINTING — APPROXIMATELY £90-170 TRADE): ONE OF THE MOST WIDELY USED PERIOD-PROFILE DOOR RANGES FOR VICTORIAN RENOVATION. XL JOINERY VICTORIAN (SOLID SOFTWOOD — PRIMED — SIMILAR PROFILE — APPROXIMATELY £80-160 TRADE). ALSO AVAILABLE IN SOLID OAK (RICHARD BURBIDGE PINNACLE OAK VICTORIAN 4-PANEL — £250-400 FOR STAIN AND VARNISH FINISH).

2-PANEL DOOR (ALSO PERIOD-APPROPRIATE — FOUND IN BOTH LATE GEORGIAN PERIOD BEFORE THE VICTORIAN ERA AND EARLY VICTORIAN PROPERTIES — AND COMMON IN THE UPPER FLOORS AND SERVICE ROOMS OF MID-VICTORIAN LONDON TERRACES): THE 2-PANEL DOOR (TWO TALL VERTICAL STACKED PANELS — SEPARATED BY A MID-RAIL) HAS A CLEANER, MORE MINIMAL AESTHETIC THAN THE 4-PANEL DOOR — FOUND IN THE SIMPLEST PROPERTIES AND THE UPPER-FLOOR BEDROOMS AND SERVICE AREAS OF LARGER VICTORIAN TERRACES.

6-PANEL DOOR (LATE VICTORIAN AND EDWARDIAN PERIOD — 1890-1910 — ALSO VERY APPROPRIATE FOR EDWARDIAN CONVERSIONS OR LATE VICTORIAN TERRACE RENOVATIONS): THE 6-PANEL DOOR (THREE ROWS OF TWO PANELS — OR TWO ROWS OF THREE — DEPENDING ON THE ARRANGEMENT) IS THE DOMINANT DOOR PROFILE OF THE LATE VICTORIAN AND EDWARDIAN PERIODS — AND IS THE MOST 'GEORGIAN' OF THE VICTORIAN-ERA PROFILES. APPROPRIATE FOR: EDWARDIAN TERRACES (POST-1900); LATE VICTORIAN TERRACES (POST-1890) WHERE THE ORIGINAL DOORS MAY HAVE BEEN 6-PANEL.

FLUSH DOORS (MODERN HOLLOW-CORE OR SOLID-CORE MDF — FLAT FACE — NO RAISED PANELS): INAPPROPRIATE FOR A PERIOD VICTORIAN TERRACE RENOVATION — SHOULD BE REPLACED WITH APPROPRIATE PERIOD PROFILES UNLESS THERE IS A SPECIFIC PRACTICAL REASON FOR FLUSH CONSTRUCTION (E.G. VERY NARROW HALLWAY WHERE A RAISED PANEL DOOR FRAME WOULD REDUCE THE OPENING BELOW ACCESSIBILITY REQUIREMENTS).

FIRE DOOR REQUIREMENTS (FD30S — 30-MINUTE FIRE RESISTANCE — SMOKE SEAL — TO BS EN 1634-1) APPLY TO SPECIFIC LOCATIONS WITHIN A LONDON VICTORIAN TERRACE UNDER BUILDING REGULATIONS APPROVED DOCUMENT B (FIRE SAFETY — VOLUME 1 — DWELLING HOUSES): THE MOST COMMON LOCATION WHERE FD30S FIRE DOORS ARE REQUIRED IN A LONDON VICTORIAN TERRACE IS WHERE A LOFT CONVERSION HAS BEEN CARRIED OUT — APPROVED DOCUMENT B REQUIRES THAT THE STAIRCASE SERVING THE LOFT BEDROOM(S) IS ENCLOSED WITHIN A FIRE-RESISTING ENCLOSURE (30-MINUTE FIRE RESISTANCE — FR30) INCLUDING FD30S FIRE DOORS AT EVERY OPENING OFF THE STAIRCASE — TO PROVIDE A PROTECTED MEANS OF ESCAPE FROM THE UPPER STOREYS OF THE BUILDING.

FD30S FIRE DOOR SPECIFICATION: FD30 (30-MINUTE FIRE DOOR — BS EN 1634-1 TESTED — MUST BE CERTIFIED BY AN ACCREDITED CERTIFICATION BODY — TYPICALLY BWF-CERTIFIRE, FIRAS, OR BM TRADA Q-MARK): JELD-WEN FD30S SHAKER (THE MOST WIDELY SPECIFIED FD30S PERIOD-PROFILE DOOR FOR LONDON VICTORIAN TERRACE LOFT CONVERSION STAIRCASE ENCLOSURES): AVAILABLE IN 4-PANEL PERIOD PROFILE (JELD-WEN FD30S SHAKER 4-PANEL — PRIMED SOFTWOOD — 1981X838MM, 1981X762MM, 1981X686MM — APPROXIMATELY £180-280 TRADE). LPD DOORS FD30S RANGE: ALSO AVAILABLE IN PERIOD PROFILES (LPD FD30S VICTORIAN — PRIMED SOFTWOOD). XL JOINERY FD30S: SIMILAR RANGE.

FD30S DOOR INSTALLATION REQUIREMENTS (NON-NEGOTIABLE — THE DOOR MUST BE INSTALLED AS A COMPLETE CERTIFIED ASSEMBLY TO MAINTAIN THE FIRE-RATING): INTUMESCENT STRIP + COLD SMOKE SEAL: THE 'S' IN FD30S MEANS SMOKE SEAL — AN INTUMESCENT STRIP (WHICH EXPANDS IN FIRE TO SEAL THE GAP BETWEEN DOOR LEAF AND FRAME) PLUS A COLD SMOKE SEAL (TYPICALLY A BRUSH PILE SEAL — WHICH SEALS AGAINST COLD SMOKE BEFORE THE FIRE IS HOT ENOUGH TO ACTIVATE THE INTUMESCENT) MUST BE FITTED IN THE DOOR FRAME REBATE OR IN A GROOVE IN THE DOOR LEAF EDGE. LORIENT LAS23 (20MM X 4MM INTUMESCENT STRIP WITH COLD SMOKE SEAL — THE MOST WIDELY SPECIFIED PRODUCT FOR FD30S DOORS IN UK RESIDENTIAL CONSTRUCTION — USED IN THE DOOR FRAME REBATE) IS THE RECOMMENDED SPECIFICATION. THREE HINGES (NOT TWO — THREE HINGES ARE REQUIRED FOR FD30S FIRE DOORS — TWO HINGES ARE NOT ADEQUATE TO MAINTAIN THE DOOR IN ITS FRAME UNDER FIRE CONDITIONS): FIRE-RATED CE-MARKED HINGES (CARLISLE BRASS OR SIMONSWERK — 3 NO. GRADE 13 BALL BEARING BUTT HINGES — 102X76MM OR 100X75MM — STAINLESS STEEL OR SATIN CHROME). FIRE-RATED DOOR CLOSER (FD30S DOORS MUST BE FITTED WITH A SELF-CLOSING DEVICE — BUILDING REGULATIONS APPROVED DOCUMENT B REQUIRES FIRE DOORS TO BE SELF-CLOSING IN PROTECTED STAIRCASE ENCLOSURES): PERKO PC100 (OVERHEAD DOOR CLOSER — CONCEALED IN THE DOOR FRAME HEAD — THE MOST PERIOD-DISCREET CLOSER FOR VICTORIAN TERRACE APPLICATIONS) OR DORMA TS68 (EXPOSED OVERHEAD CLOSER). FIRECO DORGARD (FIRE DOOR HOLD-OPEN DEVICE — ALLOWS FIRE DOOR TO BE HELD OPEN LEGALLY — RELEASES AUTOMATICALLY ON ACTIVATION OF FIRE ALARM — USEFUL WHERE FIRE DOORS ARE FREQUENTLY USED BETWEEN KITCHEN AND HALLWAY): OPTIONAL BUT FREQUENTLY SPECIFIED.

THE DOOR LINING SET (THE FRAME WITHIN THE STRUCTURAL OPENING — COMPRISING THE HEAD LINING AND TWO SIDE LININGS — TO WHICH THE DOOR IS HINGED AND WHICH CARRIES THE DOOR STOP AGAINST WHICH THE DOOR CLOSES) AND THE ARCHITRAVE (THE MOULDED TRIM THAT COVERS THE GAP BETWEEN THE LINING AND THE SURROUNDING WALL PLASTER OR PLASTERBOARD) ARE AS IMPORTANT TO THE PERIOD AUTHENTICITY OF THE INSTALLATION AS THE DOOR LEAF ITSELF.

DOOR LINING SETS (CHESHIRE MOULDINGS — THE LEADING UK SUPPLIER OF SOFTWOOD MOULDED TIMBER JOINERY COMPONENTS — INCLUDING DOOR LINING SETS, ARCHITRAVES, SKIRTINGS, AND DADO RAILS FOR THE RENOVATION MARKET): STANDARD LINING SET (27MM THICK X WALL THICKNESS WIDE — TYPICALLY 107MM, 119MM, OR 133MM WIDE FOR STANDARD TIMBER-FRAMED AND MASONRY PARTITIONS IN A VICTORIAN TERRACE) — SUPPLIED IN THREE PIECES (HEAD PLUS TWO LEGS) — FIXED TO THE STRUCTURAL OPENING WITH SCREWS INTO TIMBER PACKING PIECES (FIXING PACKERS NAILED OR SCREWED INTO THE MASONRY OR TIMBER STUD AT EACH SIDE AND HEAD OF THE OPENING — AT 450MM CENTRES — THE LINING IS THEN FIXED TO THE PACKERS WITH SCREWS AND PLUGGED). REBATED LINING (27MM LINING WITH A 12MM DEEP REBATE MACHINED INTO THE FACE — PROVIDING AN INTEGRAL DOOR STOP — NEATER AND LESS PRONE TO BEING KNOCKED OFF THAN A PLANTED DOOR STOP): AVAILABLE FROM CHESHIRE MOULDINGS AND RICHARD BURBIDGE.

ARCHITRAVES (THE MOULDED PROFILE TRIM THAT FRAMES THE DOOR OPENING ON EACH FACE OF THE WALL): PERIOD-APPROPRIATE ARCHITRAVE PROFILES FOR A LONDON VICTORIAN TERRACE: OGEE PROFILE (THE MOST COMMON VICTORIAN INTERIOR ARCHITRAVE — AN S-CURVE SECTION — CHESHIRE MOULDINGS 57X20MM OGEE PRIMED MDF OR SOFTWOOD). TORUS PROFILE (A SEMI-CIRCULAR CONVEX SECTION — SLIGHTLY SIMPLER AND MORE EDWARDIAN/ARTS-AND-CRAFTS — CHESHIRE MOULDINGS 57X20MM TORUS PRIMED). OVOLO PROFILE (SIMILAR TO OGEE BUT WITH DIFFERENT S-CURVE PROPORTIONS — MORE GREEK REVIVAL AND EARLY VICTORIAN — CHESHIRE MOULDINGS). ALL AVAILABLE FROM BUILDERS MERCHANTS (TRAVIS PERKINS, JEWSON, BUILDBASE) AT APPROXIMATELY £2-5/M FOR PRIMED MDF OR SOFTWOOD.

THE DOOR FURNITURE (IRONMONGERY — HANDLES, HINGES, LATCHES, AND BOLTS) IS THE DETAIL THAT MOST DIRECTLY REFLECTS THE PERIOD CHARACTER OF THE INSTALLATION — AND IS ALSO THE DETAIL MOST OFTEN COMPROMISED IN BUDGET RENOVATIONS BY THE SPECIFICATION OF CHEAP CHROME HANDLES THAT ARE COMPLETELY INAPPROPRIATE TO A VICTORIAN TERRACE INTERIOR.

PERIOD-APPROPRIATE DOOR HANDLES FOR A LONDON VICTORIAN TERRACE: CARLISLE BRASS (A LEADING UK MANUFACTURER AND IMPORTER OF ARCHITECTURAL IRONMONGERY — THEIR PERIOD RANGES ARE WIDELY SPECIFIED FOR VICTORIAN TERRACE RENOVATION): CARLISLE BRASS MANITAL LUCIA LEVER ON ROSE (SATIN BRASS — THE PERIOD-APPROPRIATE FINISH FOR A VICTORIAN TERRACE — OR ANTIQUE BRASS OR POLISHED BRASS DEPENDING ON THE INTERIOR PALETTE): £20-40 PER PAIR. CARLISLE BRASS ALBA LEVER ON ROSE (POLISHED CHROME — FOR A CLEANER, CONTEMPORARY-WITH-PERIOD INTERPRETATION — LESS AUTHENTICALLY VICTORIAN BUT POPULAR IN RENOVATED TERRACES): £15-30 PER PAIR. PERIOD HOUSE STORE (AN ONLINE RETAILER SPECIALISING IN PERIOD-APPROPRIATE ARCHITECTURAL IRONMONGERY FOR GEORGIAN AND VICTORIAN PROPERTIES): A GOOD SOURCE FOR: VICTORIAN RING PULLS (FOR INTERNAL DOORS — THE MOST AUTHENTIC DOOR FURNITURE FOR A LONDON VICTORIAN TERRACE INTERIOR), CERAMIC KNOBS (WHITE PORCELAIN OR OCTAGONAL BONE CHINA — THE MOST COMMON DOOR KNOB MATERIAL IN ORIGINAL VICTORIAN TERRACE INTERIORS), AND SOLID BRASS RIMLOCK SETS (THE ORIGINAL LOCKING MECHANISM ON VICTORIAN INTERNAL DOORS — A SURFACE-MOUNTED RECTANGULAR LOCK BOX ON THE FACE OF THE DOOR — RATHER THAN A MORTISE LOCK RECESSED INTO THE EDGE).

HINGES (BUTTS — HINGES FOR INTERNAL DOORS): STANDARD INTERNAL DOORS (NON-FIRE-RATED): TWO HINGES ARE ADEQUATE (MINIMUM 75X50MM BUTT HINGES — PRESSED STEEL FOR ECONOMY, BALL-BEARING FOR QUALITY — MATCHING THE DOOR FURNITURE FINISH — SATIN BRASS WITH BRASS HANDLES, SATIN CHROME WITH CHROME HANDLES). FIRE-RATED FD30S DOORS: THREE HINGES MANDATORY — CE-MARKED FIRE-RATED GRADE 13 BALL-BEARING HINGES (CARLISLE BRASS OR SIMONSWERK — 102X76MM).

BEYOND THE FIRE-RATING AND PERIOD PROFILE, TWO FURTHER TECHNICAL CONSIDERATIONS ARE FREQUENTLY OVERLOOKED IN INTERNAL DOOR SPECIFICATION FOR A LONDON VICTORIAN TERRACE RENOVATION: ACOUSTIC PERFORMANCE AND ACCESSIBILITY.

ACOUSTIC SEALS (FOR DOORS TO BEDROOMS, HOME OFFICES, BATHROOMS, OR BETWEEN OPEN-PLAN KITCHEN-DINING AND THE SLEEPING ACCOMMODATION): BUILDING REGULATIONS APPROVED DOCUMENT E (RESISTANCE TO THE PASSAGE OF SOUND) SETS REQUIREMENTS FOR SOUND INSULATION BETWEEN ROOMS IN CONVERTED PROPERTIES — BUT EVEN WHERE APPROVED DOCUMENT E DOES NOT STRICTLY APPLY, ACOUSTIC SEALS ON INTERNAL DOORS SIGNIFICANTLY IMPROVE THE ACOUSTIC PERFORMANCE OF THE DOOR WITHOUT CHANGING ITS APPEARANCE. LORIENT LAS23 (20MM X 4MM INTUMESCENT STRIP WITH COLD SMOKE SEAL — ALSO PROVIDES SIGNIFICANT ACOUSTIC BENEFIT — SEALING THE GAP BETWEEN THE DOOR LEAF EDGE AND THE DOOR STOP): ALSO AVAILABLE IN NON-INTUMESCENT FORM (LORIENT LAS3 — BRUSH PILE ONLY) FOR ACOUSTIC-ONLY APPLICATIONS (NON-FIRE-RATED DOORS). THRESHOLD SEAL (LORIENT LTX THRESHOLD SEAL — DROP-DOWN SEAL OPERATED BY THE CLOSING MECHANISM OF THE DOOR — SEALS THE GAP BETWEEN THE BOTTOM OF THE DOOR AND THE FLOOR — SIGNIFICANT ACOUSTIC IMPROVEMENT — ALSO IMPORTANT FOR ENERGY EFFICIENCY WHERE THE DOOR IS IN AN EXTERNAL-FACING POSITION — E.G. UTILITY ROOM DOOR). ACOUSTIC DOOR: A SOLID-CORE DOOR (NOT A HOLLOW-CORE DOOR — HOLLOW-CORE HAS VERY POOR SOUND REDUCTION) IS THE STARTING POINT FOR ACOUSTIC PERFORMANCE. A SOLID SOFTWOOD 4-PANEL DOOR (LPD OR XL JOINERY) WITH PERIMETER SEALS (LORIENT LAS3) AND THRESHOLD SEAL (LORIENT LTX) CAN ACHIEVE RW 28-32 DB — ADEQUATE FOR A BEDROOM OR HOME OFFICE DOOR.

ACCESSIBILITY (BUILDING REGULATIONS APPROVED DOCUMENT M — CATEGORY 2 AND 3 DWELLINGS — NOT MANDATORY FOR ALL PROPERTIES BUT BEST PRACTICE): MINIMUM CLEAR OPENING WIDTH FOR WHEELCHAIR ACCESS: 775MM CLEAR OPENING (FOR A STANDARD WHEELCHAIR). THIS MEANS A MINIMUM DOOR LEAF WIDTH OF APPROXIMATELY 840MM (775MM CLEAR MINUS THE DOOR LINING REBATE AND HINGE POSITIONS). MOST STANDARD VICTORIAN TERRACE INTERNAL OPENINGS ARE 686MM WIDE LEAVES — WHICH GIVES A CLEAR OPENING OF ONLY 650-660MM — BELOW THE PART M CATEGORY 2 MINIMUM. WHERE ACCESSIBILITY IS A PRIORITY, CONSIDER WIDER DOOR LEAVES (762MM OR 838MM) IF THE STRUCTURAL OPENING IS LARGE ENOUGH — OR OFFSET PIVOT HINGES (WHICH ALLOW THE DOOR LEAF TO SWING CLEAR OF THE OPENING AND INCREASE THE EFFECTIVE CLEAR WIDTH BY 50-70MM).

DOOR INSTALLATION SEQUENCE (TYPICAL FOR A LONDON VICTORIAN TERRACE RENOVATION): STEP 1 — MEASURE THE STRUCTURAL OPENING ACCURATELY (HEIGHT AND WIDTH AT TOP, MIDDLE, AND BOTTOM — VICTORIAN TERRACE OPENINGS ARE RARELY PERFECTLY SQUARE). STEP 2 — FIX LINING SET (PLUMB AND SQUARE — CHECK WITH SPIRIT LEVEL — PACK WITH SOFTWOOD PACKERS AS NECESSARY). STEP 3 — PLANE DOOR LEAF TO FIT (3MM CLEARANCE ON EACH SIDE AND HEAD — 8-10MM AT THRESHOLD FOR CARPET OR 3-5MM FOR HARD FLOOR). STEP 4 — MARK HINGE POSITIONS (TOP HINGE 150MM FROM TOP OF DOOR — BOTTOM HINGE 225MM FROM BOTTOM — THIRD HINGE MIDWAY — FOR FD30S). STEP 5 — CHOP HINGE RECESSES (CHISELLED — EXACTLY FLUSH WITH DOOR EDGE AND LINING FACE). STEP 6 — FIT LATCHES AND HANDLES (DRILL MORTISE LATCH POCKET — 95-103MM FROM DOOR EDGE — FIT LATCH — FIT HANDLE PLATE AND SPINDLE). STEP 7 — HANG DOOR (FIX HINGE LEAVES TO DOOR — FIT TO LINING — ADJUST). STEP 8 — FIT DOOR STOP (ON LINING FACE — AGAINST WHICH THE DOOR CLOSES — PLANTED DOOR STOP — 12X38MM SOFTWOOD — OR INTEGRAL REBATE ON REBATED LINING).
