Rising energy prices, climate change, new legal regulations: It’s never been more important for home owners to save energy effectively. A particularly efficient method here is roof insulation because the roof is, together with windows and walls, most often responsible for energy loss in a house. Up to 20% of warmth is lost through a roof that is not or not sufficiently insulated – and that generates unnecessarily high heating costs. With the tesa ISO SYSTEM®, we offer you a compact solution that enables you to insulate your roof quickly and easily on your own!
If you as a home owner would like to save some money, you should take a closer look at the energy efficiency of your roof. Without insulation, a great deal of energy and warmth is lost here. In order to optimally insulate your roof, not only will you need the right insulation material but also an airtight layer: a so-called vapour barrier.
The vapour barrier foil completes the roof insulation and helps reduce energy loss and thus utility costs. The right insulation also increases the value of a building, maintains the standing fabric and creates a pleasant air quality. In winter, the cold stays outside, and in the summer time, the insulation functions as protection against the heat. If you want to remodel your attic and convert it into living or office space, you should pay particular attention to quality when selecting your insulation. At the end of the day, the attic will be spared temperature shifts which might otherwise cause structural damage.
When it comes to installing roof insulation on your own, our three-component system provides you with everything you need: The tesa ISO SYSTEM® is a compact solution for creating a reliable airtight layer. The professional, optimally coordinated products offer an adhesion that’s resistant against age and failsafe.
1st component: tesa ISOFIX® 1 vapour barrier foil forms the basis
The tesa ISOFIX® 1 tear-proof vapour barrier foil helps save energy costs and is at the heart of the tesa Iso System®. While the vapour barrier protects the roof from moisture during the winter, it also contributes to drying any remaining moisture in the summer. The vapour foil is very thin and light, making it easy to apply with a stapler.
2nd component: The 2-in-1 adhesive tape tesa ISOFIX® 2 seals the foil
The 2-in-1 adhesive tape, tesa ISOFIX® 2, for vapour barriers and vapour seals is ideally suited to creating an airtight layer. With the robust adhesive tape, you can seal the vapour barrier foil (ISOFIX® 1). You can also use the adhesive tape to quickly and securely create an airtight seal for overlaps or holes.
3rd component: tesa ISOFIX® 3 sealing glue
The tesa ISOFIX® 3 sealing glue closes the gaps between the stonework and the vapour barrier foil (ISOFIX® 1).
The vapour foil is applied under the wooden structure to which the drywall tiles are attached, for example, in front of the insulating material. Attaching the foil is very simple as it is very light, can be easily unrolled, and there is a practical measuring and cutting aid printed on it. You have to staple the foil in intervals of approximately 30 cm to the rafters and let it protrude some 10 cm. Make sure you attach the foil in such a way that it sags a little. In the next step, seal overlaps and other unsealed areas with the adhesive tape (ISOFIX® 2). In order to seal the airtight layer, affix the overlapping foil with the cartridge glue (ISOFIX® 3) to the walls.
Roof insulation with the tesa ISO SYSTEM® is an investment that will pay off. Here you can find an overview of the many advantages:
