HIGH-PERFORMANCE AND SAFE

The ALMO 220g underlay sets new standards in roof technology with its four-layer, grid-reinforced structure. It not only offers outstanding diffusion capacity (Sd value 0.02 m) and robustness, but also excellent fall-through protection that meets the strict criteria of DIN 4426.

✓

UV-RESISTANCE

Equipped with a 3-month UV resistance and rated fire class E, our underlayment offers reliable performance in various environmental conditions, making it the ideal choice for numerous construction projects.

✓

OUTSTANDING VAPOR PERMEABILITY

With an sd value of 0.02 m, the UV underlay promotes excellent moisture regulation, improves the indoor climate and effectively prevents mold growth.

✓

APPLICABLE FROM ROOF PITCH > 10°

The ProLine 220G is versatile and can be used for roof pitches from 10°.

✓

WATERPROOF AND OPEN TO DIFFUSION

With a surface weight of 220g/m² and a W1 classification for resistance to water penetration, our underlay membrane guarantees protection against driving rain while remaining open to diffusion and enabling optimum moisture regulation.

✓

USER-FRIENDLY ASSEMBLY

Installation is simplified by two integrated self-adhesive strips, enabling quick and easy installation. This efficient installation method saves considerable time and guarantees lasting reliability and performance.

ProLine roofing membrane installation instructions

Step 1: Align and prepare the roof membrane

The ALMO ProLine sarking and underlay membrane should be laid starting at the lower part of the roof pitch and parallel to the eaves. The printed side is the upper side and faces the installer during installation. The membrane is rolled out directly onto the rafters or onto the fully sheathed roof. The underlay should protrude slightly after positioning.

Step 2: Attachment in the eaves area

In the eaves area, the roofing membrane must be fastened under the counter battens on the eaves sheet or above the eaves batten on the gutter lashing. At the same time, water pockets and counterfalls should be avoided. Fasten the underlays to the rafters with nails or staples.

Step 3: Nail sealing tape and counter battens

To keep the rafters watertight, we recommend using a strip of our Nail sealing tape 60 under the counter battens. After spreading the membrane, counter battens and battens should be attached. The counter battens create a gap between the membrane and the battens. Ensure that all points where nails or staples pass through the membrane are sealed with nail sealing tape and are located under the counter battens.

Step 4: Overlapping and bonding underlayments

Another strip of membrane should be applied with a 10-15 cm overlap. To make the installation of the roofing membrane efficient, avoid draughts and keep the overlaps watertight, use the adhesive strips integrated with the membrane, which are glued together.

Step 5: Ridge sealing

For non-ventilated roof constructions, the membrane goes over the ridge to seal it against snow and rain. For ventilated roof constructions, the roof membrane should be approx. 5 cm from the highest ridge point. This ventilation opening should also be secured with a strip of roofing membrane fixed over a counter batten so that the membrane overlaps the roof surface by approx. 20 cm.

Step 6: Sealing for eaves

In the case of roof projections such as chimneys, the sheets should be cut, pulled out and fixed with the ALMO Versa Uni Tape be sealed. Separate strips of membrane are glued to the surface and at the corners. An inclined foil gutter can be installed above penetrating building components. To form a temporary covering, connections to rising building components must also be bonded and secured to prevent them from running behind.

Step 7: Seal overlaps to make them windproof

The resulting overlaps must be bonded laterally and transversely if wind-tightness is required. For a replacement overlap, the membrane strip of a foil gutter is extended to below the next ridge-side height overlap and taped all the way around. The open joints at the corners are taped to make them rainproof. Roof windows are integrated into the opening and fixed in place. If counter battens or the resulting frame are further away from the window, separate strips of membrane can be attached.
