We have curated a specialised "Low Pitch Lineup" consisting of 6 advanced interlocking clay roof tiles. These profiles are specifically designed to maintain exceptional weathering performance at angles where other roof tiles typically fail.

The standout performance of this collection belongs to the ERLUS AG Karat RS.

Engineered with a deep interlocking bars, the Karat RS can be safely specified down to 7° pitch, a technical capability unique to the UK roofing market. This allows architects and contractors to achieve a premium, natural clay aesthetic on ultra-low pitch extensions and modern builds without resorting to metal or synthetic cladding substitutes.

From sharp, minimalist flat profiles of the Planum and Level RS to classic pantile aesthetics like the E58 and Selectum, this range provides robust technical solutions for demanding design briefs.

👉 Review the technical profiles and minimum pitch capabilities and speak to our team about which profile will best suit your project.

Ready to upgrade your roof windows but not sure what type or size you have?
Then you need your "ID Card."

Every VELUX window made since 1968 has a specific Type Sign that tells you exactly what you have. No tape measure required! 📏❌

Where to look:
🪟Open your window (pivot it toward you).
👀Look at the top left corner of the sash.
🕵️Check behind the ventilation flap.

🧩 Cracking the Code:
Your data plate will show a string of characters. Here is what they mean:
1. Type: (e.g., GGL) – This tells us the opening style and material.
2. Size: (e.g., MK04) – This is the code for your dimensions.
3. Variant: (e.g., 7070) – Defines the pane type and exterior finish.
4. Production Code: Tells us exactly when your window was born!

Just snap a clear photo of this plate and send it to us. We’ll do the heavy lifting and find the perfect replacement flashing or upgrade for you!
