The K2 roof can achieve a combined U-value of 1.6, using:


• Either PVC-u or aluminium roof system (U-value 3.1)


• Celsius one glazing (centre pane U-value 1.0)


• Slope Factor adjustment as laid out in BRE doc BR443 (<20° U-value 0.4)


“For our Integra and Venetian orangery roof systems the standard insulation is 0.20,” Sharon added. “If you put in an additional quilt in the void this can easily reach 0.18. Therefore, ALL K2


conservatory roof and orangery products when glazed with either Celsius one or Celsius Elite, can meet the “energy efficiency provisions from non- exempt conservatories and porches.”


She pointed out that other regulations may have to be taken into account such as “Document A Structure.”


A final note was made concerning the removal


of doors or walls between the house and the extension.


If this is going to happen you will need to commission a full Carbon Emissions (SAP)


report for the existing house, plus a “Notional” complying extension.


You will then do a Carbon Emissions (SAP)


report for the existing house and plus the conservatory. The CO rating for the conservatory and house must be equal to or less than that of the “notional extension” and house.


K2 would like to thank all of the people who attended to the Open Days.
