U Values

Thermal Values

Slenderpane slim double glazed units can achieve a range of u values to suit the nature of the project.

Sightlines of our warm edge spacers do not affect the thermal value and these are 6mm Heritage, 7mm, 8mm, 9mm and 11mm.

N.B. We recommend that a minimum of 3mm o/a is deducted from the tight size of the opening to arrive at the unit size.

The lower the u value the better the thermal efficiency of the unit.
