This saves you labor hours, minimizes cutting waste, and keeps your job site more efficient. In addition, the roof elements are exceptionally walkable for safe handling.

2. Excellent thermal performance

Thanks to custom-made delivery, there are fewer seams and gaps in the roof structure. This ensures an optimal connection between the elements, limits heat loss, and contributes to an energy-efficient and high-performing roof.

3. Fire safety

Unidek Sarking XL is manufactured from fire-retardant modified EPS Platinum. Combined with a suitable fire-resistant interior finish, this contributes to a fire-safe roof structure and extra peace of mind for construction professionals and end users.

4. Vapor-permeable and moisture-resistant

Thanks to its vapor-permeable nature, Unidek Sarking XL is easy to combine with existing finishes and insulation materials. Furthermore, the closed-cell structure of EPS makes the roof element exceptionally moisture-resistant and dimensionally stable, which contributes to a durable and reliable roof construction.

5. Sustainable choice

Thanks to the custom-made nature of Unidek Sarking XL, cutting waste on the job site is kept to a minimum. Moreover, the core made of EPS Platinum 100% is recyclable, and the product's long lifespan contributes to a sustainable and future-proof roof insulation solution.

Unidek Aero Comfort

Structurally insulating and sound-insulating roof element

Unidek Aero Comfort forms an efficient basis for pitched roofs. Thanks to the continuous insulation core of EPS Platinum, thermal bridges are minimized and a high thermal performance is achieved. The integrated stiffeners enable large spans, while the fast installation contributes to smooth execution on the job site. Available in Uc-values from 0.27 to 0.10 for various new construction and renovation projects.

1. More comfort – Soundproofing

Thanks to the integrated plasterboard panel, Unidek Aero Comfort offers excellent sound insulation performance. Ambient noise and sound transmission between homes are reduced, resulting in higher acoustic comfort for the end user.

2. Free choice of interior finishing

Unidek Aero Comfort is available with a neat white visible side or with a sturdy gypsum fiberboard that can be finished as desired. This creates maximum flexibility in the finish and the space under the roof can easily be set up as, for example, a bedroom or study.

3. EPS Platinum

The core of Unidek Aero Comfort consists of EPS Platinum, a durable and efficient insulation material with excellent thermal performance up to passive house level. This contributes to an energy-efficient and future-proof roof structure.

4. Strong and constructive roof element

The combination of integrated edge stiffeners, impact-resistant sheet material, EPS Platinum, and a 12 mm plasterboard makes Unidek Aero Comfort a very strong and reliable roof element. Thanks to the patented stiffeners, the element is also self-supporting up to nearly 6 meters, which contributes to an efficient and stable roof construction.

5. Faster placement

Unidek Aero Comfort is very quick to install on site. In many cases, it is possible to make a standard roof wind- and watertight in a single day. Thanks to custom-made delivery, including the desired ridge bevel, the margin for error is greatly reduced and installation is more efficient and precise.

Class of fire

Unidek Aero Comfort features an excellent reaction to fire with Euroclass C-s2-d0. This performs better than the standard requirements of D or E that are imposed on construction products, depending on the type of building and application. Thus, the roof element contributes to a safe and compliant roof structure.

7. Advantages
