Middle layer:

Breathable monolithic PU film

Bottom layer:

Non-woven PP fabric

Top layer:

Highly UV ray-stabilised PP non-woven fabric

The layers are bound with a solvent-free acrylate dispersion, and the product is backed with a pre-cut removable plastic film to aid the self-adhesion process.

Superior Breathable Membrane

Traspir Tightwrap is easily comparable, indeed superior to the popular alternatives such as Wraptite. Ideal for both commercial and residential buildings, its ease of use saves on both labour and materials, whilst providing a robust airtight barrier that remains vapour permeable, and UV resistant.

Permanent UV Stability

UV resistance is permanent even when exposed to open joints on façades up to 35 mm wide and uncovering a maximum of 30 % of the surface area for façade application.

Repositionable

In case of a mistake during installation, the membrane can be repositioned and reapplied without difficulty.

The special polymer compound makes the membrane waterproof and airtight, but vapour permeable. This makes it easier for any seepage to dry out and protects the structure.

Frequently asked questions

Is Trapsir Tightwrap suitable for use in both residential and commercial buildings?

Yes, Trapsir Tightwrap can be used on both residential and commercial buildings. Its easy installation and market leading performance make it a reliable solution for a range of construction projects, from homes to large commercial structures.

What is the permeability rating of the Tightwrap airtight membrane, and why is it important?

Key to its overall performance, the vapour permeability of Trapsir Tightwrap allows moisture vapour to pass through without letting water in. This permeability prevents condensation buildup, which can lead to mould, mildew, and structural damage, particularly in walls and roof membranes. It ensures that your building stays dry and maintains a healthy indoor environment.

How does Tightwrap membrane contribute to energy efficiency in buildings?

As a highly effective airtight membrane, the Tightwrap membrane prevents air leakage, which reduces the loss of internal air. This creates a more energy-efficient building envelope, which helps to lower heating and cooling costs. Its breathable membrane design also allows moisture vapour to escape, preventing condensation and improving indoor air quality.

How long does Trapsir Tightwrap building membrane last once installed?

The Tightwrap membrane is engineered for long-term durability. Its robust construction, including resistance to UV rays and weather, ensures it remains effective for the life of the building. Its ability to withstand wear and tear makes it a highly reliable choice for both roof membranes and house wrap membranes.

Does the Tightwrap airtight membrane meet the requirements for passive house construction?

Yes, the Trapsir Tightwrap meets the requirements for passive house construction. Its combination of airtightness, waterproof breathable membrane properties, and energy efficiency makes it ideal for passive house projects, where controlling air leakage and maintaining a healthy, breathable environment is critical.

Is Tightwrap resistant to UV rays and other environmental factors?

Yes, in fact, the Tightwrap membrane offers excellent resistance to UV rays and harsh environmental conditions. Unlike many alternatives, its UV resistance is permanent, even when exposed to open joints on façades up to 35 mm wide. This makes it an ideal waterproof breathable membrane that can withstand the rigours of construction sites and prolonged exposure to the elements.

How does the Tightwrap breather membrane perform in terms of water resistance and breathability?

The Trapsir Tightwrap delivers a perfect balance of water resistance and breathability. It acts as a waterproof breathable membrane, preventing external moisture from entering the building while allowing internal vapour to escape. This dual functionality helps protect your structure from water damage while promoting a healthy, dry interior environment.
