Illuminated business signage covers the lettering above a shop, the illuminated box on a workshop gate, the projecting sign that catches a driver before the turning, and the free-standing totem at the entrance to a yard. We build all of these in Győr and install them ourselves in the Zagreb area. This page sets out which construction suits which building, how a sign is fixed through an insulated facade without leaving a cold bridge or a leak, how bright is bright enough at night, and what documentation we hand over with the finished job.
Illuminated signage in Sesvete — manufacturing, installation, quote
Croatia · 300 km from our plant in Győr
Look along Zagrebačka cesta after dark and you see what kind of place this is commercially: two and three storey buildings with a shop or a workshop below and flats above, a tyre fitter next to a bakery next to a pharmacy, and behind them the newer estate at Novi Jelkovec where nothing is more than fifteen years old. An illuminated sign in Sesvete is therefore almost never a solitary object on a blank corporate facade. It sits under somebody's bedroom window, beside a neighbour's sign of a different colour and age, on a wall that may be brick, may be rendered blockwork, and increasingly is external insulation over both. The design problem is not how to be seen. It is how to be seen clearly at forty metres while remaining a good neighbour at midnight.
Four constructions and their honest price order
From painted face to individual halo-lit letters
The illuminated box with a printed acrylic face is the least expensive and the most forgiving of an uneven wall; it reads well and it dates quickly. Individual letters with an illuminated face are a considerable step up in appearance and cost, and they suit a name of eight or ten characters, not a slogan. Halo-lit letters, lit from behind onto the wall, are the quietest of the family and work beautifully on a plain rendered surface, but they need a clean background to glow against. A free-standing totem at a yard gate, of the kind that suits the units at Sesvetski Kraljevec, is a different animal again, since it needs a foundation and a supply of its own. The right choice is usually driven by the name itself: a short name suits letters, a long one suits a box.
Facades with a hundred and fifty millimetres of insulation
Fixing through, not into, the render
External insulation is now the normal condition on the renovated buildings of the district and the standard one at Novi Jelkovec, and it changes the whole fixing method. The render and the insulation carry nothing. Anchors have to pass through to the structural wall behind, using spacer sleeves so that tightening the fixing does not crush the insulation, and every penetration is sealed against water tracking down inside the system. On the rendered blockwork common around Trg Dragutina Domjanića and the market, the drilling positions are set out from a template made in our workshop, so that on the day nothing is measured on a ladder. A sign that was screwed straight into an insulation board will be hanging crooked within two winters, and the damage it does to the facade costs more than the sign.
Output after the flats above go to bed
Two levels, one timer
The luminance a sign needs at six in the evening in December is not the level it should hold at one in the morning, and the difference is not marginal. Every sign we build is wired for two-level operation with a timer or a light sensor, so the daytime level is chosen for legibility and the night level for coexistence. On a street where flats sit directly above the shopfront, that second setting is the difference between a sign nobody complains about and a sign that ends up switched off permanently by an exasperated tenant. It also saves electricity across a year, which is a smaller argument but a real one.
Colour, contrast and the name that has to be read
What survives at forty metres
Legibility at distance comes from contrast and letter height, not from saturation. A deep blue letter face against a dark wall vanishes at dusk however brightly it is driven; the same letter in white or warm white reads from the far pavement. As a working figure, a capital letter of ten centimetres is comfortable at around thirty metres for a stationary reader, and a driver needs considerably more. If a corporate identity insists on a colour that will not perform, the usual compromise is a coloured logo element next to white lettering, which keeps the brand and keeps the readability.
Supply, protection and the paperwork of the electrical side
What the installing electrician leaves behind
An outdoor sign runs from a low-voltage power supply in a sealed enclosure, protected on its own circuit, with an isolator that somebody can actually reach. The enclosure and the cable glands are rated for outdoor use, drainage is provided at the lowest point of any box so condensation has somewhere to go, and the earthing is documented. We hand over a wiring schematic, the data sheets for the supply units and a photographic record of the fixings before they were covered. This is dull material until the day a fault has to be found by somebody who was not there, at which point it is the whole job.
The first five years of a sign
Cleaning, ageing and replacement parts
LEDs do not usually fail; they fade, and they fade unevenly if half the sign faces the afternoon sun. A wash twice a year removes the film of road dirt that Zagrebačka cesta deposits on everything, and it makes a measurable difference to apparent brightness. The parts that genuinely fail are the power supplies, which is why we specify a size that has spare capacity rather than one working at its limit, and why we leave the replacement type recorded. Warranty runs one or two years depending on the construction. Beyond that, a service visit from Győr at 300 kilometres is a single day's work, and it is worth combining with any other maintenance the building needs.
