How to Choose Shutters

Close the louvres and the room quietens. Open them and they disappear into the frame. Four questions decide the material and the configuration.

How do you choose the right shutters for a South African home?

  1. PVC shutters for coastal and humid homes: moisture-proof, no warping, no repainting
  2. Aluminium security shutters where security matters: security, privacy, light control and insulation in one product that replaces burglar bars, curtains and blinds
  3. Timber shutters only inland where humidity is low, and with periodic maintenance
  4. Never timber in bathrooms, kitchens or coastal rooms
  5. Configuration matters as much as material: hinged for standard windows, bi-fold or bypass past 1.8m
  6. Custom Lifestyle Shutters are made to Custom Blinds Shutters & Awnings’ specification in Cape Town and fitted across the Garden Route after a site visit

Four questions for choosing shutters, in order

Exposure first, security second, maintenance third, opening size fourth. Answer them in sequence and the shutter chooses itself.

  1. ExposureCoastal or humid: PVC or powder-coated aluminium only. Inland and dry: any material, timber included
  2. SecurityIf yes: aluminium security shutters, with 3-pin locking and reinforced louvres. On ground-floor bedrooms, stacking doors and anything reachable from outside
  3. Maintenance toleranceZero: PVC, wipe clean, no repainting. Willing to refinish every few years: timber, inland
  4. Opening sizeStandard window: hinged. Wider than 1.8m or a stacking door: bi-fold or bypass

PVC, aluminium, timber

Hinged, bi-fold or bypass

How the panels open, how much window they clear, how they look when open.

PerformanceHingedBi-foldBypass

Best forStandard-width windowsWide openings, stacking doors, feature windowsVery wide openings where folding panels would be unwieldy

Panels should not exceed 900mm wide; wider panels strain the hinges. The site visit sets the configuration.

04   Why 89mm louvres

The widest standard plantation blade, on every installation.

Not a supplier constraint: an aesthetic judgement held across more than twenty years of Garden Route shutter work. Fewer, wider blades sit more comfortably in a frame, close cleaner, and open to a less obstructed glass. At 45 degrees, diffused light with full privacy; fully open, the glass largely clear. Narrower louvres are a different look, available elsewhere, and not offered because they do not produce a better outcome.

At the site visitFrame depth, panel width and hinge placement are confirmed to the opening. The louvre width is fixed.

Questions buyers ask about choosing shutters

Which shutters are best for a South African home?

PVC for coastal and humid homes and wet rooms, aluminium security shutters where security leads, timber only in dry inland rooms. Custom Blinds Shutters & Awnings fits its Custom Lifestyle Shutters range across the Garden Route after a site visit.

Are PVC shutters as good as timber?

For durability and maintenance, better: moisture, UV and humidity do not warp them and they never need repainting. Timber has the warmer natural grain and needs upkeep, especially near the coast.

How much do shutters cost in South Africa?

Every shutter is custom made, so the price depends on material, opening size, configuration and colour. Custom Blinds Shutters & Awnings provides an itemised quote after the site visit; shutters are not priced online.

Can shutters replace curtains and blinds?

Yes. Many homeowners remove curtains entirely: adjustable light, complete privacy when closed, and insulation against heat and cold in one product.

Do shutters add value to a property?

Yes. Estate agents list them as a premium feature and treat them as a permanent architectural improvement.

Which shutters are best for coastal homes?

PVC indoors and aluminium for security. Both resist salt air and humidity. Avoid timber in direct coastal exposure.
