Thermal Performance

The thermal performance of Profix’s Residence 9 sash window frames can accommodate 28mm double or 44mm triple glazing that offers market performance when it comes to energy efficiency.

In most circumstances, it will outperform a like for like spec timber window, and has already been tested to give U Values of 1.2 W/m²K and 0.8 W/m²K achieved with 28 and 44mm argon filled units that meet thermal requirements for passivhaus and a Window Energy A Rating.

Traditional windows and doors with thermal performance of the R9 range from Profix will reduce energy bills while enhancing the appearance of period homes.
