With a clarity similar to glass, it is far more robust, and will prove to be far easier to install maintain.

What are the Key Benefits of this Sheet?

This optically clear sheeting allows for a very high level of natural light to pass through it, making the interior of any structure it is used on significantly brighter. However, you won’t have to worry about harmful rays, as this sheet also benefits from long life UV protection. The light weight of this sheet makes it extremely easy to handle and install, and its fantastic fire performance, melting away from the flames and thus aiding the prevention of the spread of fire, is unrivaled on the market.

Storage Recommendations

We recommend storing sheets internally, on flat and dry surfaces, in cool environments, to limit the risk of distortion caused by solar heat gain. If outdoor storage is unavoidable, store on wooden bearers (spaced at approximately one-meter centres) and cover ALL sheets with an opaque, light-coloured tarpaulin.

Delivery Information

We understand that ordering products online can be daunting, especially when ordering roofing materials. It is for this reason that we make our delivery processes as simple as possible for you. However, there are a few things to know about our delivery processes. These include:

  • When placing an order, you’ll see a breakdown of your delivery charge in your shopping cart. These charges are for the UK mainland only, and additional charges may apply for Northern Ireland, the Scottish Highlands and other regions.

  • Deliveries only take place on working days (Mon - Fri) and do not take place on Bank Holidays. 

  • You’ll find an estimated delivery on the majority of product pages below the 'Add to Basket' button. Whilst we aim to deliver your items within the estimated delivery, it is only an estimate. 

  • You're able to select a preferred delivery date in your shopping basket. Whilst we aim to deliver your items on this date, it is not guaranteed.
  • Orders placed after 12pm, during the weekend, and on a bank holiday will not be processed until the next working day. Please consider this when placing your order as it may impact your delivery date.

  • After you’ve placed your order, you’ll receive an order confirmation by email outlining the details of your order. Please check your order confirmation email and inform us of any mistakes or errors immediately.

  • Shortly after receiving your order confirmation you’ll receive a separate email confirming the planned delivery date.

  • We can only provide a delivery date and are not able to confirm the time delivery will be attempted. Therefore, we ask that somebody is able to accept and sign for your items throughout the started delivery date.

  • If you are unable to accept and sign for an order, it can be left in a safe location in most circumstances. Please email [email protected] if you would like an item to be left without a signature. 

  • Whilst we aim to hold the majority of our products in stock, due to the vast number of products we offer this is not always possible. Because of this we are required to send your items directly from the manufacturer on a small number of occasions, at which point a different delivery charge may apply as standard.  

  • On occasions the items ordered may be shipped from different depots, which could result in seperate deliveries taking place.

If you have more questions about our products or delivery, please contact our team online or by telephone.
