"Our super soft almond thermal lining is a luxurious 180gsm and is made from recycled polyester and responsibly sourced cotton. Offering several insulating benefits that have been independently tested and proven by laboratory tests. The results show a ten-fold increase* in thermal resistance when compared to a standard thermal lining, it's so effective it has an equivalent 2.2 tog rating! Specifically developed to help boost heat retention to reduce drafts, conserve energy and keep the warmth in. Thus helping with the rising costs of energy for your clients. Trapped air creates the thermal resistance and the most effective barrier to keep the cold out and the warmth in. *Thermal resistance (K-M/W) independent results show thermal resistance at 0.2322 for the super thermal lining and 0.0286 for the standard thermal lining . Tested under 10°C-30°C test conditions."
