Grade 3 Insulation

ALL YEAR ROUND COMFORT

All models in the 2017 Auto-Sleepers motorhome range meet the NCC EN1646-1 Grade III classification for heating and thermal insulation, meaning every 2017 model excels in any environment to deliver luxurious year round touring comfort.

The classification was achieved after completing rigorous testing inside Truma’s state of the art Cold Chamber facility in Derby, where the vehicles were subjected to extreme temperatures of -15°C which is extremely challenging for an all steel body to overcome as it absorbs the cold and fights the heating system.

In order to achieve Grade III status, the centre of the interior must achieve a minimum temperature of +20°C within a 4 hour period despite the freezing temperatures surrounding the vehicle throughout the test. Auto-Sleepers new tank heater blankets, which form part of the new winter pack, allow for free flowing water, meaning Auto-Sleeper will excel in any environment for true motorhoming freedom.grade-3-logo-big
