SAP Calculations - Extensions

SAP Calculations For Extensions

Building regulations state that the proposed glazed area within your extension should not exceed 25% of the proposed extension floor area. However, most extension designs these days have significantly more glazing than this. If you are extending your home and want to have more glazing than the 25% rule allows, we can produce a specific type of SAP calculation that enables you to do this.
