Descripción general

Las cercas de privacidad de vinilo utilizan tablas verticales machihembradas encajadas en rieles de alta resistencia que nunca necesitan pintura ni barniz.

Requieren gran precisión en la distancia entre postes ya que los rieles modulares encajan en alojamientos troquelados de fábrica con holguras justas.

Supuestos

  • Sections are 8-foot (or 6-foot) wide pre-engineered tongue-and-groove privacy kits.
  • Posts are 5x5 inch hollow vinyl structural profiles embedded in concrete.
  • Bottom rails include internal galvanized steel or aluminum reinforcement channels.
  • Layout assumes flat or stepped grade with post caps and hardware allowances included.

Errores comunes

  • Desviar la distancia entre postes impidiendo que las lenguetas de los rieles traben con seguridad.
  • No colocar el refuerzo de aluminio en el riel inferior, provocando hundimiento central del panel.
  • No reforzar con poste metálico interior los postes donde cuelgan portones pesados.
  • Fijar uniones con apriete excesivo impidiendo la dilatación térmica del PVC en verano.

Fórmulas de cálculo de vallas

La misma matemática que aplica la calculadora, en lenguaje sencillo. Nada es una caja negra.

  • Tramos

    sections = max(ceil(effective run / post spacing), 1)

  • Conteo de postes

    posts = (sections + 1) along the run, minus named corner and end posts already placed, plus 2 gate posts per gate

  • Tramo efectivo

    effective run = total length - sum of gate widths

  • Conteo de travesaños

    total rails = sections x rails per section

  • Conteo de pickets

    pickets = ceil(run in inches / (picket width + gap)); total = ceil(raw x (1 + waste %))

  • Paso board-on-board

    pitch = picket width - 1 in overlap

  • Conteo de paneles

    full panels = floor(run / panel width); add 1 cut panel if the remainder is over 0.01 ft; total = ceil(raw x (1 + waste %))

  • Volumen de hormigón

    per-hole = pi x (diameter / 2)^2 x depth; total = per-hole x posts; bags = ceil(total / bag yield)

  • Tramo ajustado por pendiente

    slope run = effective run / cos(atan(slope % / 100)); shown alongside, counts use the flat run

  • Coste

    materials = (posts x post price + rails x rail price + infill x unit price + 60 lb bags x bag price) x regional multiplier; labor = effective run x labor per ft x terrain multiplier x regional multiplier; installed total = materials + gate hardware + removal + permit + labor

Guía de compra

A vinyl privacy fence calculator has to account for the tongue-and-groove panel construction that sets vinyl privacy apart from both wood privacy and vinyl's own picket style: vertical boards interlock into a routed top and bottom rail as a sealed section, so there is no individual picket count, only a panel width and a post spacing that must match it exactly. The general vinyl fence calculator covers panel systems broadly, while this one is sized specifically around 6 foot opaque privacy sections, the height most municipalities treat as standard for backyard privacy fencing. Anyone instead planning an open, see-through style in the same material should use the vinyl picket fence calculator, since picket spacing and cap style change the hardware count even though the post and panel logic underneath is similar.

Posts carry more of the structural load in a privacy fence than in an open picket style, since a solid 6 foot panel catches far more wind than a picket fence with open gaps between boards. That is why gate posts and end posts commonly get internal reinforcement, steel rebar or a concrete fill inside the hollow vinyl post itself, while ordinary line posts rely on the outer footing collar alone. Sizing that footing correctly means running the post count through a fence post calculator first and then a concrete bags calculator for the actual bag count, rather than estimating concrete from the linear footage of fence. The vinyl fence installation guide covers the full footing depth and reinforcement sequence for exactly this kind of heavier panel in more detail.

Vinyl privacy sits at the upper end of the cost range among common privacy fence materials, and the clearest way to see where it lands relative to wood, chain link and aluminum is the comparison in this fence material cost comparison, since the gap between materials narrows or widens depending on local supply and installation labor rates. Composite is the other common long-lifespan privacy option, built on boards and rails rather than hollow panels, and comparing it directly through the composite fence calculator is worth doing before settling on vinyl purely on appearance, since the two materials differ more in installation method and panel weight than in finished look. Anyone wanting a wood-built privacy comparison for reference should check the privacy fence calculator, which uses the board-by-board wood formula instead of the panel formula used here.

Privacy fence height and placement are two of the most commonly regulated aspects of residential fencing, since a solid 6 foot or taller fence affects sightlines and setbacks in a way an open picket fence does not. Checking local rules before finalizing height and property-line placement is worth doing through this state-by-state permit overview and the more detailed property line and setback guide, since a privacy fence built a few inches over a setback line or past a stated height limit is a far more common and more expensive mistake than a bad material estimate. Maintenance-wise, vinyl privacy panels hold up well to routine washing but still benefit from an annual rinse to clear algae and mildew buildup in shaded yards, and impact damage from storms or falling branches is the more likely long-term failure point on a tall solid panel than ordinary wear.

The full set of panel and board calculators for low-maintenance materials, including both vinyl styles and composite, sits on the vinyl and composite calculator hub, which is worth a look before finalizing a privacy fence plan, since the height, style and material choices interact more than they first appear to, particularly around post reinforcement and footing size once the fence height passes 6 feet.

Grade changes are one of the more overlooked variables on a privacy run, since a solid 6 foot panel that is level across its own width can still leave a gap at the bottom on sloped ground, or sit noticeably proud of the soil on the downhill side if the layout does not account for it. Stepping panels down a slope in increments, with each section staying level and the post height adjusted at each step, is the common approach for tongue-and-groove vinyl, since the rigid rail and interlocking boards generally do not rack to follow a continuous grade the way some open picket or metal panel systems can. Getting the step height consistent across the whole run also keeps the top line of the fence visually even from a distance, which matters more on a privacy fence than on an open style precisely because there is no gap between boards to visually break up a slightly uneven top rail. Planning for this before ordering posts and panels, rather than discovering the slope mid-installation, avoids a mismatch between the panel heights ordered and the step count the actual grade requires.

Preguntas frecuentes

¿Como afecta la dilatación térmica al vinilo?

El PVC se expande y contrae hasta 1/4 de pulgada por tramo de 8 pies. Los rieles deben conservar holgura dentro de los postes ranurados.

¿Llevan concreto por dentro los postes de vinilo?

Normalmente no, salvo en los postes donde bisagra o cierra un portón, donde se inserta varilla y concreto o alma de acero de refuerzo.

¿Como se limpia una cerca de vinilo blanco?

Con manguera de jardín, agua jabonosa suave y cepillo suave. Para verdin y polvo bastara una hidrolavadora a presión moderada.

¿A que profundidad se entierran los postes de vinilo?

Para 6 pies de altura, los postes de 5x5 se entierran de 30 a 36 pulgadas con cimiento de concreto de 10 a 12 pulgadas de ancho.

¿Que componentes forman un panel de privacidad de vinilo?

Tablas machihembradas verticales, riel superior ranurado, riel inferior con canal de aluminio y dos perfiles en U de remate lateral.

¿Se puede instalar en terrenos con desnivel?

Si, mediante escalonado de paneles en cada poste o utilizando paneles especiales basculantes que admiten hasta 10 grados de pendiente.

¿Se quiebra el vinilo con el hielo invernal?

El vinilo virgen para exterior incorpora modificadores de impacto e inhibidores UV que mantienen flexibilidad en temperaturas bajo cero.

¿Cuanto dura una cerca de vinilo de calidad?

Suele durar entre 25 y 30 años o mas sin requerir mantenimiento salvo limpiezas anuales ocasionales con agua.
