Frequently Asked Questions

Do PolarLight acrylic blocks have a plastic appearance?

The high grade acrylic used in the manufacture of our blocks has the look and clarity of a crystal grade of glass. Most people believe that our panels are made from glass until they touch their surface. Indeed, PolarLight acrylic blocks look clearer than many glass blocks on the market, which often contain a green or brown tint.

How are PolarLight acrylic block panels/windows installed?

Our block panels are delivered completely framed and ready to install. They can be installed by screwing the nail fins on the frame to wooden batons in stud walls. They can be fixed to block-work using standard window ties in a similar way that new uPVC windows are installed. If using the panel as a partition with an exposed edge, our flat endcap can also be used for fixing. The endcap can be screwed to a flat surface, such as a tiled wall, and the panel will snap securely into it.

Our unique 'drop-glaze' panels can be fitted into standard uPVC windows as a replacement for the normal glass unit. This allows for an exclusive opening block window.

How long does it take to get a PolarLight acrylic block panel delivered?

Most small orders in the UK & Ireland are delivered within 4 weeks of ordering.

How does the cost compare to glass block construction?

The installed cost of a PolarLight acrylic block window is generally less than building with traditional mortared glass block. However, there are costs with glass block that are difficult to estimate, delays due to curing time, work required for floor strengthening, quality issues, etc. Therefore, on larger scale projects, PolarLight acrylic block panels can offer significant savings over glass blocks.

Can I use PolarLight panels as shower walls?

The panels are engineered as external windows, and are completely waterproof, so are often used as part of a shower. However, it should be noted that, like all acrylic products such as baths, care must be taken with cleaning. Harsh bathroom cleaners may harm the acrylic blocks over time. This must be kept in mind if using them in a shower. See cleaning instructions below.

The wave pattern is on the inside of the block, and the outside is completely smooth. This makes for easier cleaning and less watermarks. We use a special mildew resistant white silicon between the blocks.

Which block patterns should I consider if I wish to use them for privacy?

Our Frosted Wave blocks have the distinctive Wave pattern on one side and a sandblasted effect on the other. Also, our Elegant block design, which has a 'cut glass' ribbed effect, and our Radiant blocks also offer good privacy. View our acrylic block designs.

Will the blocks yellow?

Our acrylic is highly UV stabilized and does not turn yellow.

Will the blocks scratch?

Acrylic blocks will scratch easier than glass. However, with normal use, scratching isn't a problem. Should a block get a scratch it can be easily removed using a plastic polish.

How do I clean acrylic blocks?

Clean your acrylic blocks with a solution of mild soap (dishwashing liquid) and lukewarm water. Use a clean soft cloth, applying only light pressure. Rinse with clean water and dry by blotting with a damp cloth or chamois. For a sparkling shine, use Pledge® furniture polish after cleaning.

DO NOT USE: Abrasive pads, alcohol, paint thinners, solvents, tile cleaners, abrasive cleaners, window cleaning sprays. or shower scrubs - always check with the cleanser's manufacturer for compatibility with acrylic.

If external DO NOT clean in hot sun.

What if a block gets broken?

If a block is cracked or broken, a block replacement kit is available. The damaged block is removed and a replacement block is installed in its place.

How easy is it for a burglar to break through an acrylic block window?

Although acrylic blocks can be broken with a hammer, as the window is made of individual blocks, each block would need to be broken in order for someone to enter through the window. It would be much quicker and easier for a burglar to break through a normal glass window.
