A poor frame and single glazing is a cold surface which causes discomfort.
It feels like sitting beside an open frigde and even with heavy drapes the cold sneaks up on you
Everyone around here who has changed to double glazed PVCu or timber windows from single glazed wood or aluminium (without having changed anything else in the house!!) is going on about how much warmer the house is
Theory is one thing, the real physical experience is the other
True if you were to snuggle up close to an uncovered window on a winter night or actually leant against the pane Most people don't this. If you stay within reasonable limits of the external envelope the ambient air temperature is nowhere like that experienced near the window itself. The effect is lessened even more with a reasonably fitted window covering. Moreover, there is enough radiant heat from the interior structure to provide adequate comfort. Part of the discomfort near a sunless window is that there is no significant radiant heat approaching from that angle. That is negated the further away you move from it.
I am talking about sitting close to th window e.g. sofa or desk
Are you suggesting to move the sofa or desk to the middle of the room just to work around a crap window ??
Are you suggesting to run around the house after sunset to shut all curtains??
What if I come home late? Is the heat I "gained" in the day gone because
I wasn't home to shut the curtains ?
What if we don't insulate the walls at all and install heavy drapes and pelmets to cover all external walls at night including the windows
I wan't a stable temperature at home regardless when I come home or leave the house.
