Which material suits which property?
Listed buildings and conservation areas
Solid timber is usually the only acceptable choice in listed buildings and conservation areas. Pine and meranti both qualify; meranti has the advantage of better long-term stability. Alu-clad timber may be accepted in some conservation areas but rarely on listed buildings — check with your local authority before ordering.
Exposed coastal properties
Coastal exposure is harsh on any material. Meranti and alu-clad meranti perform best in salt-laden air. PVC also performs well but ages visually faster in strong UV. Pine should be avoided in unprotected coastal positions unless under a substantial porch.
North-facing or shaded entrances
North-facing doors get less UV but more moisture, especially in damp areas. Alu-clad timber and PVC handle this best. Pine can work if there is sufficient shelter from rain.
South or west-facing exposed entrances
These positions get the most UV degradation, which is hardest on timber finishes. Alu-clad timber is the best long-term performer here. Meranti with high-quality opaque finish also works well; pine will need more frequent refinishing.
Urban and contemporary homes
Modern homes often suit PVC or alu-clad timber in bold colours like anthracite grey, black or deep blue. Both materials hold colour well, and the smooth surface fits the architectural language.
