Loft and Bathroom Condensation is Rising Fast
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.
Slate Vents — Your Multi-Purpose Solution
The inline slate vent is an almost invisible solution with 3 key applications:
🏠 Loft ventilation
💦 Shower fan
🚽 Soil vent pipe
Please note: Doesn't work with cooker hood extractors.

1️⃣ Vent Only
This option is perfect for loft ventilation.
If you're not connecting to any pipework (now or in the future), this option is all you need.
2️⃣ Vent + Pipe Adaptor
The pipe adaptor connects the vent to extraction units via existing pipework.
You can buy the pipe adaptor on its own later.
3️⃣ Vent + Pipe Adaptor + Flexible Pipe
The flexible pipe provides a high-quality flexible connection between the roof tile vent and existing pipework.
It can extend between lengths of 250mm - 550mm.
Adjustable ties allow diameters between 120mm - 77mm.
You can also buy the flexible pipe on its own later.
