## Description

Dolphin is a cool medium-blue speckled vinyl from the [Altro Stronghold 30](https://flooringking.co.uk/category/altro-stronghold-30) range, built for safety-critical spaces. The R12 anti-slip rating keeps people on their feet in kitchens, bathrooms and wet commercial areas where a slip could matter.

The 3mm PVC sheet sits flat and stays quiet, absorbing 10dB of sound underfoot. It's waterproof, so splashes and spills don't soak through. You don't need underlay, and the vinyl works with underfloor heating if your home or workplace has it fitted.
