Protect Performance. Preserve Efficiency

A passivhaus building minimises heat loss, relying on airtight, well-insulated, and undamaged building envelopes. Protectapeel Passivhaus sealant supports these standards by creating airtight layers during construction, helping preserve the integrity of energy-efficient buildings in both new builds and refurbishments.

Protectapeel seals gaps and cracks within the building envelope to prevent air leakage and improve thermal performance, particularly around windows, doors and critical junctions. Applied easily with an airless spray gun, it delivers precise, clean sealing and a smooth, professional finish across a wide range of substrates.

Once cured, Protectapeel forms a durable yet flexible seal that maintains airtightness despite building movement and temperature changes. By reducing air infiltration, it cuts energy loss, lowers heating and cooling costs, and supports long-term sustainability and compliance with energy-efficient building standards.

service related FAQ’s

Is protectapeel Original waterproof?2026-04-08T12:04:37+00:00

Yes, applying Protectapeel Top Coat on top of Protectapeel Original creates a waterproof barrier that effectively protects surfaces from moisture and contaminants.

How does Protectapeel compare to other protection materials?2026-04-08T12:30:49+00:00

Protectapeel offers significant advantages over traditional protective films and boards by drastically reducing labour during application and removal. Unlike films that can lose adhesion or boards that shift out of place, Protectapeel adheres securely to surfaces, ensuring consistent protection for up to 12 months.

Additionally, Protectapeel’s effective barrier minimises cleaning costs by shielding surfaces from dirt, dust, and debris. These combined benefits make it a far more cost-effective and reliable solution for construction projects.
