Webinar Recording - Rethinking IWI with Natural Fibre Insulation
Take a deep dive into thermal upgrades to solid walls using natural fibre insulation internally
Weather protection included – reliable protection against rain and moisture
Rainproof sarking boards
STEICO sarking and sheathing boards and wall panels are hydrophobic, i.e., water-repellent. Rainwater’s surface tension cannot break through sarking boards like STEICOuniversal dry but runs off the surface. The panels are provided with a tightly closing, all-round tongue and groove profile and thus offer a rainproofing function and serve as temporary covering.
Suitable as temporary covering for several weeks
STEICO sarking boards can be laid directly on the rafters without battens and instantly provide robust weather protection. Thanks to the special tongue and groove profile, they seal tightly and can be exposed to the elements on roof slopes over 16°. They fulfil three functions in one fell swoop:
- a windproof layer
- a secondary water removal layer
- additional insulation
As sarking boardss, they can be used as temporary covering for several weeks
Reduce constructive thermal bridges
Laying above the rafters effectively reduces structural thermal bridges, even with thin panels. The top of the rafters is insulated and thus warmer, significantly reducing the risk of condensation.
Additional insulation above the rafters
The rafters of old building roofs are often small, but inter-rafter insulation alone does not provide thermal protection that meets modern standards. With insulation above the rafters, the roof can be insulated in a future-proof way without taking up valuable living space under the roof. At the same time, the sound insulation is noticeably improved.
STEICO sarking boards are easy to use and enable rapid work progress
The sarking boards are laid above the rafters and "interlocked" via the tongue and groove system
The special board profile ensures reliable weather protection with rainproofing and can withstand temporary weathering
STEICO sarking boards do their job - protecting your building - right from the moment they are installed. Further roof extension can be continued in dry conditions.
The boards are attached in the rafters using the counter battens = maximum safety, even in windy storms
Water rolls off the hydrophobised panels
While STEICO sarking boards protect against rain, they are also vapour-permeable - just like good functional clothing
That’s how STEICO sarking boards work

Diffusion-open insulation materials for safe moisture management
Wetness is a danger; not just from the outside, but from the inside too. Increased amounts of moisture are produced during showering or cooking, for example. Although the insulation layer is structurally protected from moisture, small holes in the vapour barrier can result in greater moisture penetration if care is not taken. If you have used vapour-permeable insulation material, there is nothing to fear.
All STEICO insulation materials are vapour-permeable, so they allow for safe drying out. In simplified terms, the term "breathing structures" is often used. STEICO insulation materials help keep your construction dry and offer protection against moisture damage, mould and structural damage.
""Whether flexible insulation batt, rigid insulation board or air-injected insulation – all STEICO insulation materials are highly diffusion-open."
Further advantages of STEICO insulation materials
