Challenge

Insulating pitched roofs at rafter level has long been an intricate and complex job and the private developers on this project in Chester were looking for a solution which was not only cost-effective but more importantly easy and quick to install.

The installation procedure would be a difficult one, due to the unusual nature of the roof. Access would be from scaffolding, as the roof was located above an open-plan galleried entrance hall.

As well as simplifying the installation, the insulation would need to provide reliable long term performance – this requirement being intensified by the exposure of the roof to the main living space.

Solution

Knauf Insulation proposed 200mm Room-in-Roof Roll 37 as a cost-effective and easily installed method of achieving the project requirements.

Room-in-Roof Roll is a brand new foil-faced glass mineral wool roll, which is far more cost-effective than traditional rigid foam board solutions as well as being inherently sustainable, as it is manufactured using high recycled glass bottle content.

The integrated foil facing acts as a built-in vapour control layer and the overlapping facing is quickly stapled into place while friction fitting reduces the need for time-consuming cutting and fitting, commonly associated with the installation of rigid foam boards.

Outcome

The developers commented that the product was actually 3-4 times quicker to install than rigid foam boards.

Friction fitting of the product allows the rafter space to be completely filled, eliminating heat loss via air gaps and thereby maximising the thermal and acoustic performance of the roof. As a comparison, rigid foam boards are susceptible to air gaps which are often hidden by covering with foil tape or partially filling with expanding foam.

Thanks to its speed of installation, cost effectiveness and thermal efficiency, Room-in-Roof Roll is ideally suited for insulating pitched roofs at rafter level.
