Designed specifically to minimise heat loss, Planitherm One is ideal for achieving the lowest U-values. The advanced coating of Planitherm One offers insulating levels far in excess of the minimum requirements set out in Approved Document L of the Building Regulations.

Its excellent performance capability is in the name – a double glazed sealed unit featuring Planitherm One will deliver an optimum centre-pane U-value of 1.0W/m2K (16mm, 90% argon-filled cavity).

If higher thermal insulation levels are your goal, Planitherm One represents the perfect choice.

It is the most advanced thermal insulation performance within the Planitherm family, Europe’s best selling low-emissivity (low-E) glass and one of the UK’s leading offline low-E coating brands.
