Hi,
I currently have fully glazed uPVC front door with mid-rail, along with matching side panels, total width 2.1m. In the summer, the hall gets extremely hot. In the winter, it's cold (but this is less of a problem).
I'm looking into replacing the lower panels with solid panels (uPVC-Polystyrene-MDF-Polystyrene-uPVC sandwich). This works out significantly cheaper than fitting "PerfectFit"-style blinds, and has other benefits with post being visible on the floor. Solar film is ruled out due to the glass texture.
Am I likely to notice any improvement? The existing glazing units are mid-90's air-filled, tempered glass, without low-e coating or warm edge. I'm just not sure how good the ~20mm of polystyrene will be compared to the air gap in a regular double-glazed unit. I'm guessing that in any case, the solar gain will be less than a glass + blinds combination.
