Acrylic Sheet

Advantage: 30 times stronger than glass

This may sound surprising, but molded acrylic sheets are actually 30 times stronger than standard glass. This is because acrylic sheets are a form of plastic and offer greater flexibility. When molded acrylic is worked, there is only a small risk of it breaking.

Advantage: 2 times lighter than glass

Acrylic sheet or plexiglass is twice the weight of standard glass, a feature that comes in handy when you want to use it for applications such as hanging acrylic barn doors.

Advantage: Acrylic sheet is cheaper

Acrylic sheet is also recommended for those who want to save money for themselves. Not only is acrylic much cheaper than standard glass, but it is also much easier to cut to size.

Advantage: Easier processing

Ordinary glass has a high risk of breakage when processing, but with Acrylic Sheets there is no problem. Plexiglass or clear acrylic offers almost unlimited options for processing. You can saw, mill, drill, carve, glue, polish and bend these sheets.

Advantage: Plexiglass is durable

Acrylic board is very durable and will not weather or discolor. As long as you maintain it regularly, it will keep looking great for years. Plexiglass has the same level of thermal efficiency as standard glass. It is also UV and moisture resistant, which is why acrylic sheet is perfect for exterior applications.

Advantage: It lets more light through

Clear acrylic has a higher light transmission than standard glass: it lets through 92% of the light. Even with thicker sheets, it still lets more light through than glass. If you need some sunlight protection or need privacy, choose tinted or matte acrylic.

Advantage: Acrylic is safer than glass

Plexiglas is ideal for applications where safety is a concern, as it is much more difficult to break. It is also 30 times stronger than glass. This is why acrylic panels are often used for balcony glass or aquariums.

Disadvantage: Acrylic sheets are more sensitive to scratches

One of the disadvantages of plexiglass is that it scratches more easily than standard glass, so you have to maintain and clean it properly. To learn how to do this, read our blog with tips for cleaning acrylic sheets. How to clean acrylic.

Disadvantage: acrylic is not resistant to high temperatures

Acrylic sheets should never be used in security areas such as windows of trains and buses. This is because acrylic sheets are not resistant to high temperatures. If you need an alternative to standard glass that can withstand high temperatures, choose clear polycarbonate.

Clear plastic glazing sheets are excellent for greenhouses, shed windows, secondary glazing, and many other applications where glass would get easily broken. However, clear plastic sheets are not all the same. When buying clear plastic sheeting for glazing it&#;s important to realise the disadvantages of acrylic and why it should be avoided.

When it comes to glazing with clear plastic, you should avoid using any type of low-cost plastic sheets, such as acrylic sheets or polystyrene sheets. There are a lot of hidden costs and risks which you will want to avoid.

With competitive price and timely delivery, XISHUN Acrylic sincerely hope to be your supplier and partner.

Saving a small amount at the beginning of your project could cost you significant sums later with replacements. Below we have set out why you should avoid clear plastic sheets for glazing that are lower cost such as acrylic or polystyrene glazing sheets, and how making the right choice initially can provide a far longer-lasting and safer result over time.

4 Disadvantages of Acrylic Sheets:

1. Acrylic sheets have a relatively low impact strength and break easily.
2. When acrylic sheets are cut, they tend to crack
3. If you need to drill holes in the corners of acrylic sheets, they can shatter
4. Broken plastic sheets have sharp edges and spikes which could be harmful

What Glazing Sheet is Better than Acrylic?

The best clear plastic sheets for glazing are made from UV-Protected Polycarbonate. So, be sure to choose Solid Polycarbonate Sheets as they do not break like acrylic sheets do. Polycarbonate sheets are generally a bit more expensive than acrylic sheets, but you won&#;t have the cost of replacing cracked or broken panels so in the medium term they cost you much less.

Additionally, using polycarbonate sheets is a safer alternative. Although Acrylic is slightly stronger than glass it does easily break. When acrylic sheets break, they leave sharp jagged edges which are dangerous. Polycarbonate sheets on the other hand are much less likely to break as they are approximately 200 times the impact strength of glass and are generally classed as virtually unbreakable.

Polycarbonate sheets are incredibly robust against impact and can be cut and drilled easily without any breakage. They are also perfect for cold bending on curved structures.

Aside from the breakage issues with acrylic sheets during installation, you have to consider the risks after installation too. For example, in a greenhouse, a tool such as a spade could slip and fall against the glazing. Or, with a shed perhaps a ball from a ball game could impact the window by mistake. In both cases, you want to ensure you have polycarbonate sheet glazing, as this will generally withstand these impacts, whereas acrylic will tend to easily crack.

Another common application for clear plastic glazing sheets is for use in secondary glazing. Using a secondary glazing system to improve heat insulation in a house or protect windows from impact is common, particularly on older heritage properties. When making this investment the last thing you want is for the plastic to break or to quickly become discoloured. So once again, it&#;s important to choose to use a UV-protected polycarbonate glazing sheet and not a lower-cost acrylic glazing sheet.

Of course, acrylic sheets do have a purpose for applications such as indoor display areas where there is no chance of impact, and where there is no need to cut or drill the sheets on site. However, by choosing polycarbonate glazing sheets you can have total peace of mind for almost any application.

Polystyrene glazing sheets, sometimes known as styrene, are even more fragile than acrylic sheets and should be avoided completely, except for very light-duty and short-term applications in which breakage and discolouration are not an issue.

EXTRA ACRYLIC TIPS & INFO:

Is Twinwall Polycarbonate as strong as solid flat polycarbonate?

Although twinwall polycarbonate is made from very similar plastic resin and is extremely strong, because it is made from very thin layers into a structure, it can dent or crush easier than solid polycarbonate. However, twinwall polycarbonate is still much stronger from breakage than acrylic sheets and provides a lower cost than solid polycarbonate. Twinwall polycarbonate also provides a higher level of heat insulation due to the layer that makes up the structure of the sheet.

What is Perspex?

Perspex is just a brand name for acrylic sheets and has the same issues with breakage as all acrylic sheets. It is best not to use acrylic sheets for glazing applications. Instead, you can choose a quality polycarbonate sheet which is just as clear, similar to glass, and won&#;t break. Polycarbonate sheets are 200 times as strong as the same thickness of glass, which is why they are generally classed as unbreakable.

What is Plexiglass?

Plexiglass is just a brand name for acrylic sheets. It also breaks easily on impact or when cutting or drilling, and you should avoid using it in areas of high impact. The more popular choice is clear polycarbonate sheets which are over 10 time stronger and available in many thicknesses and sizes.

What is Axgard?

Axgard is a high-quality polycarbonate sheet with UV protection on both sides so it stays clear and doesn&#;t discolour. Axgard polycarbonate sheets are easy to cut to size, drill and install and is incredibly strong, so with a great impact resistance it won&#;t break with most general impacts, whether on installation or in application afterwards.

Axgard is also very long-lasting and weather-resistant and has an excellent light transmission. Axgard is available in sheets as thin as 2mm which are flexible and great for curve structures, and then up to 12mm thickness which provides excellent strength and rigidity.

Why do plastic sheets sometimes go yellow?

Some plastic sheets like clear polystyrene glazing sheets turn yellow after a few months in the sunlight. This is because the plastic is not UV protected and they are therefore not able to withstand the UV rays of the sun. This yellowing not only looks bad but also causes brittleness. UV Protected plastic sheets have a protective layer in them to prevent any discolouration and stop them from becoming fragile.
