## Overview

The Siga Majpell 5 vapour barrier offers 75 m² of high-performance roof underlay designed for quick, wrinkle-free installation and superior drying potential, making it the go-to solution for all standard roof renovation and insulation projects.

## Description

Three different applications can be covered with the universal and easy to use Majpell steam break: Intermediate and above-rafter insulation as well as roof renovation from the outside. In combination with tried and tested Siga high-performance adhesives, Majpell ensures lasting airtight building coverings for roof, wall and ceiling construction in the inner area. With a fixed SD value of 5 m on one side, Majpell is particularly dispersible. On the other hand, it offers highest level of safety, protecting the construction against moisture during the building phase, for example with fresh cast screed or fresh plaster. This means Majpell can replace variable vapour barriers, usually used especially in roof renovation. If Majpell is combined with the underlay membrane Majcoat (sd value = 0.1 m), with a diffusion gradient of 50:1, an ideal moisture wicking can be ensured.
