A front door flanked by sidelites has to do two jobs at once. From the street it has to look like it belongs on the house. From the hallway it has to behave like a window assembly, because that is exactly what the two narrow panels beside the slab are. Most buying guides treat this as a style decision and stop there, which is why so many beautiful entrances turn out to be draughty, foggy at the glass edge, or awkwardly proportioned once installed. This guide walks through the order that actually works: proportion first, then material, then the glazing and hardware specification, then finish.
Traditional architecture — Colonial, Georgian, Federal, Craftsman, Victorian, or a classic European villa — is built on proportion and symmetry rather than on ornament. The entrance is the one place where the facade declares its rules, and those rules are surprisingly consistent across styles.
Most disappointing entrances are not made of the wrong material. They are the wrong width. A slab that is too narrow between two oversized sidelites looks like a shopfront; a heavy slab hemmed in by skimpy panels looks pinched. Start by fixing the unit width, then let the material serve it. The arithmetic is simple — add the slab width to both sidelite widths and you have the rough unit width before the frame.
| Configuration | Approx. unit width | Where it looks right |
|---|---|---|
| 36 in slab + one 12 in sidelite | about 48 in | Narrow townhouse frontages, side entrances, secondary doors |
| 36 in slab + two 12 in sidelites | about 60 in | The default for Colonial, Georgian and Federal facades |
| 36 in slab + two 14 in sidelites | about 64 in | Craftsman bungalows and homes with a deep porch |
| 36 in slab + two 16 in sidelites | about 68 in | Grand entries; needs a wide stoop or portico to carry it |
| Any of the above + transom | height 96 in and up | Victorian and tall-foyer homes where the hall needs overhead light |
Height matters as much as width. The standard residential slab is 80 in, and 96 in is the usual step up for a grand opening. If you are working to a fixed structural opening rather than designing from scratch, measure width and height at three points each, check the opening for square by comparing diagonals, and record the jamb depth before ordering. These three numbers decide whether the unit fits on the first attempt. For a full breakdown of how rough openings, slab widths and entry door sizes relate to each other, measure the structural opening rather than the old door, because old frames are frequently out of square.
The conventional shortlist is wood, fibreglass and steel. All three have an honest claim, and it is worth saying plainly where each one still beats aluminium, because the answer depends on the project.
Those three also have advantages we will not pretend to match. Local distributors stock them in common sizes, the certification paperwork for a specific regional code is usually already on file, and a damaged skin can often be repaired by a local tradesperson without replacing the unit. If the schedule is measured in weeks rather than months, or the inspector wants a locally certified assembly, that route is faster.
Aluminium is usually left off the list for traditional homes because people picture a thin commercial storefront section. That is a different product category from a thermal-break system. The reason to consider a thermally broken aluminum entry door for a period-style house is dimensional, not stylistic: a broken aluminium frame carries a wider span and a taller opening with a slimmer sightline than the other three, holds its geometry instead of swelling seasonally, and can be drawn from the same profile family as the rest of the house so every frame line on the facade matches.
Style gets the photographs. These parameters decide whether the entrance is still comfortable and still closing cleanly after several winters. They are the numbers we build to on our own system platform, and they are the ones worth asking any supplier to put in writing.
| Parameter | What to look for | Why it matters at the front door |
|---|---|---|
| Profile alloy and temper | 6060-T66 | Higher precision extrusion keeps a tall sidelite frame straight instead of bowing |
| Wall thickness | 1.8 mm to 2.5 mm; main load-bearing sections 2.2 mm, locally reinforced to 3.0 mm on large openings | Stops the hinge side from gradually pulling out of alignment under a heavy slab |
| Thermal break | PA66GF25 multi-chamber strips, 34 mm to 44 mm on selected series | The single biggest defence against condensation running down the sidelite frame |
| Sealing | Dual-matrix eight-layer sealing on the AW series; triple sealing with welded corners on casement series | Keeps wind-driven rain out of the threshold, which is where most front-door complaints start |
| Hardware | ROTO transmission boxes with anti-pry lock points; Winkhaus full sets; CMECH handles tested to 30,000 cycles; Wehag options | Cycle testing is what keeps a heavy door latching correctly in year ten instead of dropping on the strike |
| Corrosion and structure | 240-hour salt spray resistance; 5,000 N shear resistance on the AW90 platform | Relevant for coastal villas and for any entrance facing prevailing weather |
| Thermal performance | K-values down to 1.3 on the AW90 passive platform | The figure to compare against, always quoted with the model it was measured on |
The slab gets the attention and the sidelites decide whether the hallway is comfortable. Each one is a fixed pane running from threshold to head, with a frame that is a genuine thermal path through the wall. Specifying them properly is where most projects either succeed quietly or fail slowly.
Adding sidelites increases glazed area next to the latch, and that changes the security calculation. A slab with a good deadbolt is only as strong as the nearest pane, because reaching through broken glass is faster than defeating the lock. Three things close that gap: multi-point engagement along the full height of the slab, anti-pry lock points at the corners, and laminated glass in the sidelite nearest the handle. Systems that distribute locking points around the full perimeter — the 360-degree layout used on our AW90 platform — also reduce the slow sag that eventually stops a heavy door from meeting the strike cleanly.
Traditional homes can carry a stronger door colour than most people expect; the door is meant to be the focal point on an otherwise regular facade. Brown Coffee sits naturally against brick, stone and Craftsman timberwork. Starry Sky Gray is the safe middle ground for a rendered or stone villa. Aurora Gray gives near-black contrast if the windows are already dark framed. Ice Cream White works when the door should read as part of the trim rather than against it. Custom colour matching is worth the lead time when the entrance has to tie back to an existing window package. One approach that reads particularly well on wide openings is a two-tone unit: a darker slab with a lighter frame, which keeps the assembly from becoming a single heavy block.
| Project | Configuration to start from | Detail to insist on |
|---|---|---|
| Colonial or Georgian restoration | 36 in slab, two 12 in sidelites, divided-lite grilles | Grille alignment between slab and sidelites |
| Craftsman bungalow | Upper-third glass, two 14 in sidelites, dentil shelf detail | Solid lower panels so the unit does not read as all glass |
| Coastal villa | Thermally broken frame, laminated sidelite glass | Salt spray rating and hardware corrosion specification in writing |
| Tall foyer or Victorian terrace | 96 in unit with transom over slab and sidelites | Head reinforcement; check the transom can be carried by the frame |
| New build in a period style | Matched door and window package from one profile family | Identical frame sightlines across the whole facade |
Sometimes, but check the frame first. If the old sidelites are single glazed or the frame is not thermally broken, a new high-performance slab next to them leaves the coldest part of the assembly in place. Measuring the existing frame also tells you whether a new slab will actually sit square in it.
They do if they are specified as decoration. Insulated Low-E glass in a thermally broken frame, with the frame sealed to the wall rather than just to the slab, keeps the added glass area close to neutral.
Stand outside facing the door. Hinges on the left means a left-hand unit. Getting this wrong is one of the most common and most avoidable ordering errors, because it cannot be corrected on site.
Usually no. Fixed sidelites seal better and cost less. If you want airflow, a transom above the slab is a cleaner solution than an operable panel beside the latch.
For a traditional home, the best entrance is a symmetrically paired unit at roughly 60 to 64 inches overall, with glazing concentrated in the upper zone, divided-lite grilles that line up across slab and sidelites, insulated Low-E glass with laminated panes near the handle, and a frame that is thermally broken on every side including the sidelites. Material follows from there: choose wood, fibreglass or steel if local stock sizing and local paperwork dominate the decision, and choose a thermally broken aluminium system when the opening is wide or tall, the climate is demanding, or the entrance has to match a window package drawn from the same profiles.
We build system windows and doors in Foshan and Zhaoqing on a 100,000 square metre production base, exporting to villa and apartment projects across the Middle East and Australia. If you are specifying an entry door with sidelites and want the frame, glazing and hardware numbers confirmed against your opening, send us the rough opening dimensions and the facade style you are matching.
