Multipared

A continuación se presentan algunas preguntas comunes sobre Multiwall.

What kinds of tools and accessories do you stock?

We stock glazing bars, F-profiles, U-channels, HP profiles, aluminium edge trims, fixing buttons, breather and foil tapes, silicone sealants and other items that make fitting plastic sheets quicker and easier.

How do I choose the right glazing bar or profile?

The starting point is the sheet type and thickness. For example, 10 mm multiwall sheets need 10 mm bars and matching U-channels. If you send us a quick sketch of your layout and tell us which sheet you’re using, we’ll suggest a full set of compatible profiles.

Why do I need breather tape and aluminium tape on multiwall sheets?

Breather tape at the lower edge lets moisture escape while keeping insects and dust out of the flutes. Aluminium tape at the top edge closes the flutes completely. This helps keep the sheets cleaner inside and reduces condensation problems over time.

Are your tools suitable for DIY as well as trade?

Yes. Our accessories are used by installers, but they’re also straightforward for confident DIY users. We choose items that work reliably with our sheet products and help you get a tidy finish.

Can I buy extra fixings or sealant if I run short?

Absolutely. Fixing buttons, tapes, glazing bars and silicone cartridges are all available separately, so you can top up what comes in a kit or order parts for a custom project.

Can you help me pick the right accessories for my project?

Yes. If you’re unsure what you need, get in touch with us by phone or through our contact page. Our team of plastic-sheet specialists can talk through your project and suggest a complete set of parts.

bsmart Collection

Below are some common questions about bsmart Collection

What is the bsmart collection?

The bsmart collection is our partnership range with a premium plastic sheet supplier. It focuses on higher-end sheets such as abrasion-resistant polycarbonate, cast and extruded acrylic, neon and opal acrylic, PETG and greenhouse panels, plus selected items like solid polycarbonate and extruded acrylic mirror within the bsmart sub-collection.

Which products sit directly under the bsmart collection tag?

Right now, the bsmart collection highlights:

  • Solid polycarbonate sheets
  • Extruded acrylic mirror sheets

These sit alongside our wider plastic-sheets range in the main menu.

When would I choose a bsmart solid polycarbonate sheet?

We suggest bsmart solid polycarbonate for demanding glazing jobs where you need clarity and very high impact resistance, for example security glazing, protective screens or industrial panels.

What can I do with extruded acrylic mirror?

Extruded acrylic mirror works well for point-of-sale units, interior features, dance or fitness studios, decorative panels and any area where you want a reflective surface without the weight and shatter risk of glass mirror.

Do bsmart sheets work with your usual accessories?

Yes. Bsmart sheets can be used with the same kinds of fixings, profiles and tapes that we supply for our other sheet products. If you are unsure which accessories to pick, just ask us and we’ll match them for you.

DIY Side Passage

Below are some common questions about DIY Side Passage

What is a side-passage roof?

A side-passage roof covers the space along the side of a house or wall, creating a dry walkway between front and back or a sheltered storage area. Our kits are long and relatively narrow to suit this kind of layout.

What’s included in a side-passage package?

Each package includes:

  • Clear multiwall polycarbonate sheets cut for the fall and length
  • Matching glazing bars
  • Edge profiles
  • Fixing buttons
  • Tapes and clear silicone

The sheets are cut, blown and taped, and the rest of the parts are matched to that configuration.

Can you adjust a kit if my passage is a different length or width?

Yes. The listed side-passage packages are guides based on typical houses. If your passage is shorter, longer or slightly wider, send us the measurements and we can adjust the sheet sizes and bar layout.

Will a polycarbonate side-passage roof be noisy in heavy rain?

Any hard roof will create some noise in heavy rain, but multiwall polycarbonate tends to soften the sound compared with bare metal sheets, and the hollow structure gives some sound dampening.

Can I add doors or screens at the ends?

Yes. Many customers close off one or both ends with acrylic or polycarbonate panels or doors to create a more enclosed space. We can supply matching sheet materials if you want to extend the cover like that.

DIY Lean-To

Below are some common questions about DIY Lean-To

What is a lean-to roof?

A lean-to roof has a single slope and is fixed to a main building on one side, slanting away from it. It’s a simple way to create a covered patio, utility area or carport along a wall.

What does a DIY lean-to package include?

A lean-to kit includes:

  • Clear multiwall polycarbonate sheets cut to the specified fall and length
  • Glazing bars
  • Edge profiles (F-profiles and U-channels)
  • Fixing buttons
  • Tapes and clear silicone sealant

So you have everything you need for the roof itself.

How do I read sizes like “3000mm (fall) x 4200mm (wide)”?

The first figure is the fall (distance from the wall down the slope). The second figure is the length along the wall. You’ll need enough space in both directions for the kit size you choose.

Can I trim the sheets on site?

You can carry out small trims with suitable tools, but we recommend using our cut-to-size service to get the main cuts done. That way you usually only need minor adjustments on site.

Are these kits suitable for DIY installation?

Many customers fit lean-to roofs themselves. The concept is straightforward, but it’s important to follow the guidance on rafter spacing and fixings and to build a safe, secure frame. Where loads are high or spans are large, a professional installer is a good idea.

DIY Free-Standing

Below are some common questions about DIY Free-Standing

What is a free-standing DIY package?

Our free-standing packages are based on a clear multiwall polycarbonate roof sitting on a pergola-style frame that stands on its own, rather than fixing straight to the house. They’re ideal for garden seating and outdoor dining areas.

Do you supply the posts and beams?

No. We supply the roofing sheets and glazing accessories. The posts, beams and main structure are supplied and built by you or your contractor.

Can I change the roof size if my pergola is different to the example kit?

Yes. The example sizes are popular layouts, but the multiwall sheets and accessories can be cut and adjusted for a custom frame. Share your frame dimensions and we’ll help you plan the roof.

Will the roof cope with Irish weather?

Our multiwall polycarbonate roofing is made for outdoor use, with UV protection and high impact strength. Fitted to a properly built frame with the right spacing, it stands up very well to wind and rain.

DIY Packages – Ready To Go

Below are some common questions about DIY Packages – Ready To Go

What is a DIY roofing package?

Our DIY packages are ready-made kits for popular roof layouts. Each one combines clear multiwall polycarbonate sheets with the glazing bars, edge profiles, fixings, tapes and sealant needed for that size and style of roof.

Do the packages include the timber or steel frame?

No. We supply the plastic roofing and accessories. You (or your builder) provide the supporting structure and fix it to your house, garden or other base.

What kinds of structures can I build with these kits?

The DIY range covers three main layouts:

  • Lean-to roofs fixed to a house or wall
  • Free-standing roofs for pergola-style structures
  • Long, narrow roofs for side passages

Each kit is based on multiwall polycarbonate roofing.

Are the panels in the kits taped and ready to go?

Yes. In line with our standard practice, panels in the DIY kits are cut, the flutes are blown clear, and the ends are taped with breather and aluminium tape, so they are ready to install.

Can you tweak a package if my sizes are slightly different?

Our listed kits are based on common roof sizes, but they are also a guide. If your project is a bit longer, shorter or deeper, let us know your measurements and we can adjust sheet cuts and accessories to suit.

I’m not sure whether a lean-to, free-standing or side-passage kit suits me. Can you help?

Of course. If you send us a rough sketch and a few photos, we can talk through the options and point you to the closest kit or a custom layout.

Clear Polycarbonate (Solid)

Below are some common questions about Clear Polycarbonate (Solid)

What is solid clear polycarbonate used for?

Solid polycarbonate is a flat, clear sheet with very high impact strength. It’s often used for safety glazing, machine guards, security screens, rooflights, canopies and similar jobs where you need clear panels that can take a knock.

How strong is it compared to glass?

Polycarbonate is far more impact-resistant than standard glass, while weighing less. That makes it well suited to exposed areas, busy workspaces and places where breakage would be a serious risk.

Does it have UV protection?

Yes. Our solid polycarbonate sheet is made from UV-stabilised resin and has UV protection on both sides, so it keeps its clarity and resists discolouration outdoors.

Can clear polycarbonate be curved?

You can cold-bend polycarbonate within the recommended radius, and it can also be formed with heat for tighter curves, domes and shaped panels. This gives you a lot of freedom for rooflights and special glazing details.

What thicknesses and sizes do you offer, and can you cut to size?

We offer a range of thicknesses (for example from around 2 mm up to heavier gauges for more demanding jobs) and standard sheet sizes. We then cut to size so you receive panels that suit your frame or opening.

Acrylic (Perspex) Sheets

Below are some common questions about Acrylic (Perspex) Sheets

What is multiwall polycarbonate, and why would I pick it instead of glass?

Multiwall polycarbonate is a hollow-core sheet that is light in weight, very tough and gives good insulation. It’s widely used for roofs, canopies, greenhouses and skylights as a practical alternative to glass.

What thickness should I choose?

A simple rule of thumb:

  • 10 mm – smaller lean-to roofs, canopies, side passages
  • 16 mm – patios, pergolas, carports
  • 25 mm – spots where extra insulation or stiffness is needed

Our multiwall guide and product pages show typical rafter spacing and uses for each thickness, and we’re happy to talk that through with you.

What sizes and colours do you supply?

We stock 10 mm, 16 mm and 25 mm multiwall sheets in standard panel sizes, with longer lengths (up to 6000–7000 mm) available on request. Clear panels are the main option, with other tints available on certain sizes.

Are the sheets UV protected, and which side faces the sun?

Yes. Our multiwall roofing sheets have a UV-protected surface. The label and datasheet show which face goes outwards; that side should face the sun to help prevent yellowing and surface damage over time.

Can you cut multiwall polycarbonate to size?

We can. Multiwall panels are cut to your measurements, the flutes are blown clear with compressed air, and the ends are taped with breather and aluminium tape unless you ask us not to. That means the sheets arrive ready for installation.

What extra parts do I need for a roof?

For a complete roof you’ll normally need glazing bars, U-channels or F-profiles, fixing buttons, tapes and clear silicone. You’ll find these in our accessories and tools collections, and we can help you match parts to your sheet type.

Multiwall Polycarbonate

Below are some common questions about Multiwall Polycarbonate

What is acrylic (Perspex), and where is it used?

Acrylic (often called Perspex or plexiglass) is a clear plastic sheet with high light transmission, good impact strength and strong UV stability. It’s a great choice for glazing, display panels, guards, screens and interior features.

Is acrylic suitable for outdoor use?

Yes. Our acrylic sheets are UV stable and can be used outdoors for signage, screens and canopies, provided they are fixed and supported correctly.

What’s the difference between cast and extruded acrylic?

Cast acrylic usually gives the best optical clarity and is ideal if you plan to machine, polish or fabricate more intricate pieces. Extruded acrylic is more economical and very consistent in thickness, which suits general glazing and cut-to-size panels.

Can I cut or drill acrylic sheets myself?

You can cut and drill acrylic with suitable blades and drill bits, but it needs care to avoid chipping or cracking. Many customers ask us to cut the sheets to size and then only do light trimming or drilling on site.

Do acrylic sheets come with a protective film?

Yes. Acrylic sheets are supplied with a thin protective film on one or both faces to help prevent scratching during transport and handling. You simply peel this off once your sheet is in place.

What colours and finishes are available?

In this collection you’ll find:

  • Clear extruded sheets
  • Black and white acrylic
  • Opal cast acrylic
  • Neon acrylic sheets in bright colours

So you can pick something very simple or something more eye-catching for displays.

Plastic Sheets

Below are some common questions about Plastic Sheets.

What types of plastic sheets do you stock?

We stock a wide range of plastic sheets for roofing, greenhouses and DIY projects. That includes acrylic sheets, multiwall polycarbonate, solid clear polycarbonate, abrasion-resistant polycarbonate, PETG, greenhouse panel packs and more.

Can you cut plastic sheets to size for me?

Yes. We offer a free cut-to-size service on our sheet materials. You give us your measurements, we cut the panels before dispatch, so you have less waste and less work on site.

Which plastic sheet is best for a roof or canopy?

For most roofs, canopies, patios and greenhouses, multiwall polycarbonate is the sheet we usually recommend. It’s light, strong and gives far better insulation than single glazing, which makes it ideal for Irish weather.

What would you suggest for clear glazing or screens?

For clear panels where looks matter, we normally suggest either acrylic or solid clear polycarbonate:

  • Acrylic for very high clarity and UV stability
  • Solid polycarbonate where extra impact resistance is important (for example, safety glazing or screens)
Do your sheets have UV protection for outdoor use?

Yes. Our roofing-grade multiwall polycarbonate has a UV-protected face, and our solid polycarbonate sheets are manufactured from UV-stabilised resin with UV protection on both sides, so they resist yellowing outdoors.

Do you deliver plastic sheets nationwide?

We ship nationwide and offer collection from our Knockmitten Lane depot in Dublin. Our goal is to get sheets cut, packed and out to you as quickly as possible.

  • Separe los botones entre 500 mm y 600 mm.
  • Perfore al menos a 40 mm del borde de la lámina.
  • Perforar entre las costillas.
  • No apriete demasiado el tornillo al fijarlo.
  • Utilice una broca de 12 mm / 13 mm para permitir la expansión y la contracción.
  • Use sellador de silicona alrededor del borde del botón para ayudar a sellar y evitar fugas.
¿Mi techo podría decolorarse en un año o dos?

Si utiliza nuestras láminas de policarbonato transparente de doble o triple pared, le ofrecemos una garantía de 10 años contra la decoloración y el amarilleamiento, siempre que se instalen correctamente. Estas láminas son de una sola cara y están protegidas contra los rayos UV, por lo que es fundamental que el lado con revestimiento UV se instale mirando hacia el cielo; las láminas estarán claramente etiquetadas como "lado UV".

¿Qué puedo usar para limpiar mi techo?

Prepare una solución de agua tibia y un limpiador doméstico común o un jabón suave y úsela para lavar la sábana. Luego, use una esponja o un paño suave para eliminar suavemente la suciedad y la mugre.

Advertencia:

- No frote la lámina con cepillos o instrumentos afilados.

- No utilice escobillas de goma.

- Evite utilizar disolventes distintos a los enumerados o cualquier limpiador abrasivo.

- Evite limpiadores de composición altamente alcalina.

¿Puedo caminar sobre un techo de policarbonato multipared?

Las láminas de policarbonato multipared para techos no están diseñadas para soportar el peso de una persona, por lo que debe evitar caminar sobre ellas. Si necesita hacerlo, use tablas para gatear entre las vigas o escaleras de mano como un medio seguro para hacerlo.

Policarbonato

A continuación se presentan algunas de nuestras preguntas comunes sobre el policarbonato.

¿Qué son las láminas de policarbonato y sus aplicaciones?

El policarbonato es un material termoplástico cuyas fantásticas propiedades y versatilidad lo convierten en el material perfecto para una amplia gama de aplicaciones.

La estructura del plástico está formada por grupos carbonato, lo que le permite ser resistente y flexible al mismo tiempo. Se utiliza mucho en el sector del esmaltado gracias a su combinación única de transparencia, resistencia y resistencia a los rayos UV.

Aplicaciones: cobertizos, solarios, cocheras, la mayoría de aplicaciones de acristalamiento, pasarelas, refugios, protectores de máquinas e invernaderos, y muchos más.

¿Qué tan fuerte es el policarbonato sólido transparente en comparación con el vidrio?

En cuanto a la resistencia de su techo: el policarbonato se considera
Prácticamente irrompible y con una resistencia al impacto de unas 200 a 250 veces más fuerte que el vidrio de seguridad convencional. El policarbonato también se comporta de forma favorable frente a otras opciones de plástico. Por ejemplo, es 30 veces más fuerte que una placa acrílica comparable.

¿Puedo cortar yo mismo el material a medida?

Sí, puedes cortar las láminas de policarbonato a medida tú mismo. Sin embargo, te recomendamos que utilices el método correcto y seguro para hacerlo. Las láminas de policarbonato se pueden cortar con una sierra circular o una sierra de calar. Una sierra circular es la mejor herramienta para cortar longitudes más grandes de policarbonato. Gracias a las propiedades de este material, el policarbonato no se agrieta ni se astilla en la zona del corte.

Puede encontrar más información aquí: Cómo cortar correctamente láminas de policarbonato

¿Puedo hacer un agujero en el material?

Sí, se pueden hacer agujeros en las láminas de policarbonato. Al hacer agujeros en el policarbonato, es importante que la lámina esté bien sujeta. Coloque la lámina sobre una superficie plana que la sujete bien y en la que el taladro pueda entrar, por ejemplo, una tabla de madera. Puede hacer agujeros en el policarbonato con una broca de acero normal o con una broca HSS.

¿Cuál es la diferencia entre láminas de policarbonato y láminas acrílicas?

Aunque son muy similares en apariencia, existen dos diferencias principales entre el policarbonato transparente y el acrílico transparente. El policarbonato tiene una resistencia al impacto mucho mayor que el acrílico; aproximadamente 30 veces más fuerte. Nuestro policarbonato tiene un revestimiento de protección UV en ambos lados que brinda una garantía de 10 a 15 años de no decoloración, mientras que el acrílico es naturalmente resistente a los rayos UV y no se decolora durante más de 20 años.

Hemos elaborado una guía práctica que cubre las diferencias entre los dos materiales, que se puede encontrar aquí .

¿Cuánto dura el policarbonato?

El policarbonato es un material resistente y duradero. Su duración depende de factores como el tipo de uso y el desgaste al que esté expuesto. Pero, en promedio, se puede esperar fácilmente un mínimo de 10 años y, potencialmente, hasta 20 años o más.

Acrílico

A continuación se presentan algunas preguntas comunes sobre nuestro acrílico.

¿Cuál es la diferencia entre acrílico fundido y extruido?

Tanto el acrílico colado como el acrílico extruido se producen a partir del mismo termoplástico base, PMMA, polimetilmetacrilato, más comúnmente conocido como “perspex” o “plexiglás”. Los diferentes procesos de producción son responsables de sus propiedades ligeramente diferentes y dan como resultado que sean adecuados para diferentes aplicaciones.
