Ordering Online
Fast, Reliable & Hassle-Free Online Ordering
Our trusted online store makes it easy for retail customers to order polystyrene products directly — no calls, no waiting. Simply browse, add to cart, and check out in minutes. It’s that easy. Need something custom or in bulk? You can request a quote directly through the platform too.

Secure, straightforward, and trusted by thousands across South Africa.
Retail vs Bulk Pricing
For Bulk Buyers & Contractors – Let’s Talk Direct
While our online store is perfect for retail orders, bulk buyers and building contractors can get even better value by requesting a custom quote. We offer discounted volume pricing, tailored solutions, and fast national delivery — all backed by expert support.

Buying in bulk? Don’t pay retail — request your personalised quote today.
Delivery Options?
Need Delivery - No Delivery Option? Let’s Make It Happen.
Due to the bulky nature of polystyrene, our online store offers limited automated delivery options.

If delivery isn’t available at checkout — don’t worry! It simply means we need to quote manually based on your location and order size.

The quickest solution? Use live chat or request a quote with all the products you need delivered, and we’ll get back to you quickly with a custom delivery option.

For large orders, we deliver nationwide — even if the system says we can’t.
For very small orders over long distances, delivery may not be feasible.

If your project is far from one of our distribution hubs, you’re also welcome to have your order delivered to a local contact or nearby business for collection.
Lead Times
Lead Times & Fast Turnaround Options
We aim to make your polystyrene ordering experience as smooth and efficient as possible.

Standard lead time:

Online orders are generally cut and delivered within 4 to 5 working days (excluding weekends and public holidays).

See the example given below.

Need it urgently?

If you’re on a tight deadline, give us a call or chat with us online — we’ll do everything we can to assist. In many cases, same-day or next-day turnaround is possible depending on your location and product needs.

We may have stock?

For extruded polystyrene ceilings: We carry stock and can usually assist very quickly.

For expanded polystyrene sheets and insulation boards: We may have stock at our Strydompark, Randburg warehouse.

We can often cut overnight for next-day delivery or collection in the regions.

The best approach? Talk to us. We’re fast, flexible, and if we can’t do it — nobody can!

Example: Ordering on a Friday Afternoon

If you place your order on Friday after 2:00 PM, processing will begin the following Monday morning. From there, your order will typically be ready for delivery or collection within 4 to 5 working days, which means it would likely be ready by Friday of the next week (or the following Monday at the latest).

Need it sooner?

Contact us via live chat or call us directly — we may be able to prioritize your order.
Refunds & Returns
Refunds & Returns Policy
Because all polystyrene orders are cut to size based on your specifications, we unfortunately do not offer returns or refunds.

However, if you need to cancel an order before cutting begins, we’ll happily cancel it and issue a full refund — no problem.

Need help? Contact us right away and we’ll do our best to assist.
