Two materials, two jobs
A venetian does something a roller can't — it steers light direction, not just quantity. Tilt up for glare-free daylight, tilt down for privacy from a neighbouring double-storey, close flat for near-dark. On a property with as much boundary wall and mature planting as Dunkeld has, that hour-by-hour control earns its keep.
- Timber & bamboo (50mm slats) — warm, architectural, and the right material for sash windows, studies and formal rooms where a "real material" reads correctly against original joinery.
- Aluminium (25mm or 50mm slats) — the moisture champion for bathrooms, kitchens and sculleries where fabric treatments fail. Wide colour range including woodlook finishes for a lower-cost alternative to true timber.
Where the adjustability argument matters most
Rooms that face a neighbour's addition, or that swing from bright morning sun to deep afternoon shade under the garden's mature trees, are exactly where a tilt-controlled slat earns its place over a simple open/closed roller.
Timber is heavier than aluminium — very wide sash bays sometimes need the blind split or ladder-tape support rather than one oversized panel, and we'll say so at the measure. Keep timber out of high-steam rooms; a quality lacquer handles normal humidity but not a shower enclosure.
