System performance

Danskin Thermal Saddle System U-value tables using Knauf Polyfoam (U-values in W/m2K for given P/A Ratios)

Data courtesy of Knauf Insulation calculated using BS EN ISO 13370:1998.

Please refer to Approved Document L1A (England and Wales) or the Technical Handbook (Scotland) for guidance on acceptable U values.

Figures in red indicate non compliance with a maximum 0.25 U Value.

85mm boards are a non stock item and may be subject to a lead in time.

The system is available with alternative insulation materials where particular performance or environmental properties are required.
Please contact Danskin for advice.
