While underfloor heating is considered an efficient way to warm rooms in domestic properties, the new building regulations outlaw this.
Reducing Heat Loss
As an alternative it is proposed that the window area is limited to a maximum of 10% of the floor area of a room. It is further noted that renovations and new buildings must allow for the installation of double glazed windows.
This together with sensible insulation can reduce heat loss by as much as 50%. It substantially reduces heat loss from inside and radiant energy gain from outside – thus regulating temperature change, keeping homes warm in winter and cool in summer.
An average of around 40 % of energy loss occurs through standard single pane glazing!
