A solar screen stops heat at the outside of the glass. Once sunlight is through the window, it is already inside the house and the air conditioner owns the problem.
External shading over glazing
Shade over a stone terraceThe physics is unglamorous and reliable: shading the glass on the outside keeps the energy out of the building. Anything on the inside is intercepting heat that has already arrived.
West-facing glass is the priority in this valley. The late-afternoon sun in August comes in at a low angle, when the house is already at its warmest and the air conditioner has been running all day.
Screens are also the cheapest intervention on this site by a wide margin, which makes them the sensible first move if a full patio cover is not in budget this year.
Shade the glass externally or the heat is already in.
Low August sun on west glass is the worst case here.
A fraction of the cost of a structure.
Installed planning range for this market, priced per sq ft of opening.
Permit fees are set by the City of Bakersfield or Kern County depending on the address, and are not published as figures on this site because no current schedule could be verified.
Jurisdiction, the openness threshold and the energy code decide more here than the finish does.
They reduce solar heat gain through the glass they cover, which is the mechanism behind cooling load on a west wall. The size of the saving depends on how much glass you have and which way it faces.
A cover shades a whole outdoor space and the wall behind it; screens shade specific windows cheaply. Many people do screens first and a cover later.
They cut visible light as well as heat. Denser weaves block more of both, so the choice is a trade rather than a free win.
Screens generally do not, being neither structural nor a building. A shade structure is a different matter. Confirm with the Building Division on (661) 326-3720 if the product attaches structurally.
Planning ranges run about $12 to $28 per square foot of opening covered.
