Loft and Bathroom Condensation is Rising
There's a big problem with roof ventilation:
🔥 You're making more heat (showers, washing, and central heating)
🏠 Your home holds more heat (double glazing, loft insulation, and cavity wall insulation)
Warm air rises. When it meets the cold surfaces of the ceilings or roof, it condensates into water droplets.
Over time, untreated loft and bathroom condensation can lead to damp, rot, and mould growth. Don't leave it until it's too late.
Rosemary Vent Tile - A Multi-Purpose Solution
The Rosemary Vent Tile is an almost invisible solution with 3 key applications:
🏠 Loft ventilation
💦 Bathroom extractor fan
🚽 Soil vent pipe
Please note: Doesn't work with cooker hood extractors.
How It Works
Easy to Install
The Rosemary Roof Tile Vent is quick and easy to fit.
One unit replaces 3 tiles. No tile or batten cutting is required. The roofing felt needs a diagonal cut for the throat of the ventilator to pass through.
- Cut and fold out the felt underlay
- Position the tile vent
- Nail securely and continue tiling
We recommend working with a professional roofer.
The Rosemary Roof Tile Vent is compatible with: Redland Rosemary Clay Classic plain tiles
This product blends in well with the Light Mixed Brindle and Medium Mixed Brindle options.
