Pitched Roof and Attic Insulation Systems
Pitched roofs and converted attics are critical structural components responsible for a building’s overall energy efficiency and climate comfort. Implementing a professionally engineered pitched roof insulation system not only drastically slashes winter heating bills but also forms a shield against extreme summer heat. By effectively sealing this zone, you transform raw under-roof areas into fully functional, comfortable, and valuable living spaces.

Stone Wool 30
Product Description
A premium slab material made of stone mineral wool. This insulation is entirely non-combustible and easy to install, creating a highly reliable barrier against cold and environmental noise.
Thanks to its optimized density of 30 kg/m³, this material features a lighter weight, which significantly reduces the structural load on building frameworks and simplifies transportation and handling on-site. The primary benefit of this density is its increased cost-effectiveness: due to lower raw material consumption during manufacturing, it delivers top-tier thermal efficiency at a substantially lower price point compared to heavier alternatives. This makes IZOVAT 30 an ideal, budget-friendly solution for non-load-bearing structural applications.

Foil-Faced Mineral Insulation Roll
Product Description
Foil-Faced Mineral Insulation Roll is a high-performance thermal insulation material made from premium glass wool, laminated on one side with a durable, reinforced aluminum foil. Due to this composite matrix, the insulation operates like a thermos: the polished foil layer reflects infrared radiant heat back into the interior space while simultaneously acting as a total vapor barrier. The presence of an integrated self-adhesive foil overlap along the edges significantly streamlines and accelerates the installation process, allowing contractors to create a completely airtight, continuous, and energy-efficient insulation envelope without requiring extra joint tapes.
Product Application
Engineered for maximum flexibility, low structural weight, and integrated vapor control, this foil-faced roll is widely utilized in the following applications:
- Comprehensive Thermal & Acoustic Insulation: Deployed in apartments, private residences, and cottages to heavily reduce heat loss and maximize indoor acoustic comfort.

Cement-Bonded Particle Boards (CPB)
Product Description
Cement-Bonded Particle Boards (CPB) are versatile, high-strength building materials that perfectly combine the structural solidity of cement with the flexibility of wood particles. Unlike wood-based sheets that rely on synthetic adhesives (such as OSB or chipboard), CPB boards are manufactured through eco-friendly compression without the use of toxic resins, phenols, or hazardous chemical additives. This process makes the material exceptionally durable, moisture-resistant, bio-stable, and entirely safe for indoor air quality and human health. The flat, dense surface provides an ideal substrate for various finishing options, including painting, plastering, or tiling.
Product Application
Engineered for multi-functional performance, cement-bonded particle boards (CPB) are heavily utilized across a wide spectrum of construction and retrofitting workflows:
- Framed Construction: Applied as a rigid material for both exterior sheathing and interior wall lining, providing a stable, heavy-duty, and fire-resistant structural core.
- Exterior & Interior Finishing: Used as a reliable, moisture-resistant substrate for modern facade systems, partition walls, suspended ceilings, and protective cladding.

System Purpose
High-performance pitched roof insulation executes several vital functions within the building envelope:
- Energy Efficiency: An uninsulated roof structure accounts for up to 25% of a building’s total heat loss. Premium insulation traps radiant heat indoors during winter and keeps solar heat out during summer, drastically optimizing utility costs.
- Acoustic Protection: Mineral wool insulation delivers superb sound absorption, dampening aggressive airborne and impact noises such as heavy rain, hail, wind, and ambient street traffic to ensure interior tranquility.
- Microclimate Optimization: Properly insulated attics maintain stable indoor temperatures, completely eliminating sharp temperature fluctuations and interstitial condensation that can trigger toxic mold, mildew, and structural wood rot.
- Fire Safety: Mineral stone wool, coupled with Cement-Bonded Particle Boards (CBPB) or Fiber Cement Boards (FCB), are non-combustible materials that dramatically elevate the overall fire protection and rating of the entire building framework.
Frequently Asked Questions
What is the main advantage of your roof insulation system compared to conventional methods?
Our integrated system flawlessly unifies two key structural functions: robust fire safety via non-combustible sheathing panels (CBPB/FCB) and elite thermal performance via mineral wool. We utilize hydro-engineered mineral insulation rolls enhanced with a specialized silicone-infused additive, providing superior water repellency.
Available in optimized widths of 400 mm and 600 mm and continuous lengths starting from 7000 mm, these rolls are tailored to friction-fit snugly between standard roof rafters. This guarantees a seamless, dense application that completely eliminates thermal bridging (“cold bridges”).
Does the system protect the roof assembly against moisture and fungal growth?
Absolutely. Thanks to their specialized composition, CBPB and FCB cladding panels are completely immune to rot, decay, mold, and fungal infestations. Furthermore, the silicone-treated mineral wool core actively repels external moisture and internal condensation, ensuring decades of structural integrity and continuous thermal performance.
How should stone wool (e.g., for facades or roofs) be stored on an active construction site?
It is vital to safeguard the material from direct moisture, humidity, and atmospheric precipitation (rain, snow). All insulation products must be kept elevated off the ground in their original factory waterproof packaging. Additionally, avoid stacking heights that could cause mechanical damage or crush the packaging.
