Pretoria’s heat
Pretoria is warmer than Johannesburg, so plan ventilation when you replace windows. Openings on two walls let air flow through a room, and a side hung window opens fully. West-facing glass needs shade, from an overhang, pergola or blinds. We supply clear laminated glass only, not tinted or double glazing. For louvred options and sliding window ranges, see aluminium windows Pretoria.
Renovation step by step
- Measure each opening once the old frame is out. Steel frames are built into the wall, so the true opening only shows after removal. Our units are made 10 mm smaller than the catalogue size.
- Order the whole house together, in one colour, so it arrives in one delivery.
- Plan the plaster repairs around each new frame with your builder.
- Keep or replace burglar bars and security gates. Check that every opening sash and door clears them.
