Description

Underlayment - perfect protection for your roof construction

A well-insulated roof is the key to an energy-efficient home. Our HaGa® roof underlay offers a state-of-the-art solution that's not only waterproof and windproof , but also boasts extreme tear resistance and high permeability . Designed to withstand even the harshest weather conditions, the vapor barrier provides reliable thermal insulation and long-term protection for your roof structure.

High-quality protection for roofs and walls

The underlay membrane is ideal for pitched roofs and building walls with batten construction . The vapor barrier offers an optimal combination of waterproofing and vapor permeability, effectively wicking moisture away from the outside without allowing water to penetrate. With a water vapor permeability of ≥1700 g/m²/24h and a permeability coefficient of 0.02 m, the underlay membrane ensures efficient insulation and prevents mold growth.

Three-layer technology for maximum efficiency

The membrane of the underlay consists of three layers of spunbonded polypropylene , providing excellent water repellency. This innovative construction of the underlay allows for thermal insulation across the entire height of the rafters without the need for additional ventilation. This keeps your roof optimally protected from the elements, while the vapor barrier simultaneously ensures perfect thermal insulation.

Why HaGa® underlayment is the right choice

Our underlayment is an essential component for any roof construction. The underlayment combines robustness, weather resistance, and excellent insulation properties in one product. The vapor barrier is easy and time-saving to install, and its high durability saves you time and money on roof maintenance in the long run.

Order the HaGa® underlayment today and benefit from optimal protection and insulation!

Frequently Asked Questions

What is the difference between underlayment and roofing underlayment?

The main difference lies in their application. An underlay membrane is laid directly under the rafters and serves primarily to keep moisture out of the interior of the building. An underlay membrane, on the other hand, is laid directly on the rafters and acts as a second water-repellent layer to prevent water from penetrating through damaged roofing.

Is an underlayment waterproof?

Yes, our underlay membrane is completely waterproof. It reliably prevents water from penetrating and thus protects the insulation underneath from moisture damage.

Is an underlayment absolutely necessary?

In most cases, an underlay membrane is essential, especially for steep roofs. It protects the insulation from moisture, improves the energy efficiency of the house and contributes to the longevity of the entire roof structure. In regions with high rainfall or strong winds, it is particularly important to prevent water and draughts from entering.
