How far it has to project to do anything
The working rule for west-facing glass in Pretoria is a projection of roughly half the glass height. A 1.2m-high window wants a 600mm awning; a 2.1m sliding door wants about a metre. Anything shallower shades the top of the glass in December and nothing at all in the late afternoon, which is when the room actually overheats. North-facing glass is the easier case: the sun is high, and a 600mm projection blocks it across the whole summer regardless of the window height.
That difference is why the same house often needs a modest canopy on the north side and a deep awning on the west. The full reasoning on Pretoria sun angles is in the sun, heat and UV guide.
The fixing fails before the fabric does
A 2.4m window awning carries a real wind load, and it is held by four to six anchors. Into solid brick that is a 10mm sleeve anchor and it holds for the life of the awning. Into plaster, or into the mortar joint of a single-skin wall, it pulls out in the first serious Highveld gust and takes a chunk of the wall with it. KB drills through the plaster into brick and sets the anchors in the brick face rather than the joint, and fits a flashing strip above the awning so rain runs off the front instead of down the wall behind it. That flashing is the part missing from almost every shelf-bought awning.
An awning bought off a shelf is sized to a standard opening and supplied without fixings, flashing or a measure — the comparison is set out under awnings for sale in Pretoria.
Fitted with the carport, on one visit
Most window and door awnings KB fits go up on the same day as a carport, in a matching colour, which is why the house reads as one structure rather than three additions. Awnings carried off the carport frame itself are carport awnings; a whole outdoor area is a patio cover. The measure that covers all of it is the same one used to quote carports in Pretoria.
Window and door awning questions
How much is a window awning in Pretoria?
R1,200 to R2,400 for a standard 1.5m window and R2,400 to R4,500 for a wide window or sliding door, supplied and installed with the fixings and the flashing. A front-door canopy runs R1,500 to R3,200.
Do window awnings actually cool a room?
Yes, and more than an internal blind does. An awning stops the sun outside the glass, so the heat never enters the room. A blind absorbs the same sunlight after it is already inside and then radiates it, which is why a west-facing lounge is still hot at five with the blinds down.
Can an awning be fitted to a plastered wall?
Yes, provided the anchors go through the plaster into the brick behind it. Fixing into plaster alone, or into a mortar joint, is what pulls out in the first Highveld gust. KB sets 10mm sleeve anchors into the brick face and flashes above the awning so water cannot run behind it.
