Renders World is the UK's largest independent supplier of premium external wall insulation systems, silicone renders, graphite EPS boards, mineral wool slabs, and professional rendering tools. Fifteen years of trade supply, nationwide next-working-day delivery, and a technical desk staffed by specifiers — for contractors, developers, and homeowners.

Where to Start on Renders World

Builders, specifiers, and homeowners across the UK source from Renders World when a job needs to land first time. Our silicone render range leads the rendering materials catalogue, alongside silicate-silicone, mosaic, and concrete-effect finishes with matching primers and basecoats — start here when you know the finish.

For full retrofit or new-build projects, Renders World supplies the external wall insulation range with graphite EPS, mineral wool, XPS, fixings, and finish layers as per-square-metre system bundles. The render beads and mesh range closes the detail — corner beads, stop beads, bellcast drips, and 150–160 g/m² fibreglass mesh in the gauges UK installers specify.

New to the specification? The Renders World silicone render buying guide and the full Renders World knowledge hub cover the decisions that come before the order — finish selection, U-value targets, and substrate preparation.

Frequently Asked Questions

Everything you need to know about EWI systems, renders, and delivery from Renders World

Need Expert Advice?

Our technical team is ready to help with system selection, U-values, and pricing

Q1 Which render system is best for my property?

Silicone render suits most UK homes — self-cleaning, vapour-permeable, and durable in coastal and inland climates. Mineral wool with silicate-silicone finish is specified for high-rise or acoustic-sensitive projects. XPS with mosaic render is the standard solution for plinths and below-DPC zones. Send the project brief to Renders World and the technical team returns a complete build-up at no charge.

Q2 How much can I save on energy bills with EWI?

An average UK semi-detached home saves £680 to £1,200 per year after installing a premium external wall insulation build-up with silicone render finish, based on 2025 mains gas and electricity unit rates. Savings scale with starting wall U-value, exposure, and heating system — solid-wall properties typically see the largest reduction.

Q3 Do you offer trade prices?

Yes — Renders World applies tiered discounts automatically at checkout: 5% off orders over £1,000, 10% off over £3,000, and 15% off over £5,000. Trade accounts unlock bespoke project quotes, consolidated invoicing, and priority access to the technical desk for system specification.

Q4 Is delivery really next-day?

Yes — 98% of in-stock orders placed before 1pm at Renders World dispatch the same working day for next-working-day delivery anywhere in mainland UK. Highlands, islands, and Northern Ireland add one to two working days depending on carrier route. Pallet deliveries for full EWI bundles require kerbside access.
