Artificial reed for thatched roofs
Natural-looking reed with performance you can specify — for thatchers, builders, and clients who want appearance and assurance together.
Roofing & performance
One material. Clear benefits.
Our modified artificial reed is made for the thatched roof: the look of natural reed, consistent workability, and documentation that supports specification and handover. The figures below back those benefits — summarised from independent testing, not verbatim report text.

The look of natural reed
Structure and colour reading stay close to a classic thatched roof, so the finished result feels warm and familiar — with industrial consistency in supply and bundle quality.
Application: roof covering with modified reed · density approx. 750 kg/m³
Confidence on fire performance
Thatchers and clients need demonstrable fire behaviour. The material is tested for reaction to fire and external roof fire exposure, so you can back performance in specs and handover.
Euroclass E (EN 13501-1) · BROOF (t2) per EN 13501-5 / ENV 1187 test 2 · 30° pitch test on 18 mm plywood
Insulation that earns its place
A thatched roof should do more than look right. Thermal resistance supports comfort and energy performance — with clear values you can place alongside other building elements.
R ≈ 3.7 m²·K/W at approx. 196 mm thickness (EN 12667) · λ₁₀ ≈ 0.053 W/(m·K) · Kiwa BDA thermal testing
Weather & durability in practice
Weather tightness and wind-driven rain sit in the documentation pack. That keeps the roof conversation on performance and service life — not appearance alone.

Workmanship with something to hold onto
Consistent material quality gives the thatcher predictable installation and the client peace of mind on specification. Performance and appearance belong to one story — not separate “product” and “lab” blocks.

Not only the roof
Reed that works beyond the roof
The same warm material suits projects meant to last longer than a season. Think garden, terraces, and craft — a lighter tone, with the same serious quality behind it. And not just one shade: colour can play along.
01Reed baskets
Sturdy, natural-looking baskets for storage, market stalls, or gifts that feel as if they came from the garden.
02Garden fencing
A soft, green boundary for plots, terraces, and patios — privacy without the cold look of hard fencing.
03Outdoor & craft
Screens, decorative panels, hobby and lifestyle projects where reed sets the mood and stays the course.
More than one shade
Alongside familiar straw tones, we can also produce reed in other finishes — from warm natural hues to more distinctive colours that suit your project. Basket, screen, or garden fence: colour is part of the story. Tell us what you have in mind.
In short: a long-term solution for anyone who wants the feel of reed — even when no roof is involved. Got an idea or a colour in mind? Send us a note through the contact form.
