The ARC Retrofit Eaves Insulator was developed to address heat loss at the eaves junction of the existing housing stock in the UK. The eaves junction, where a pitched roof meets the wall, is a difficult detail to insulate retrospectively due to space constraints and therefore is prone to excessive heat loss.
Historically, mineral or glass wool was stuffed into this detail; however, this blocks the ventilation path from the eaves into the cold loft space and can result in mould formation and condensation in the structure.
If the installer estimates a ventilation gap, it is very difficult to ensure an appropriate ventilation path is maintained whilst fully insulating the eaves. A gap in the insulation at the eaves detail will result in a thermal bridge and a cold spot on the internal walls where moisture in the air can condense and mould will begin to grow.
The ARC Retrofit Eaves Insulator is easy to install, ensures insulation right up to the wall plate, and maintains a ventilation path as required in the regulations.
The ARC Retrofit Eaves Insulator is to be used when continuous insulation from the loft to external wall insulation or the cavity is not possible. This may be the case when the path is blocked by a wall plate or the cavity is capped. The ARC Retrofit Eaves Insulator is best used when ventilation in the loft space is achieved through the eaves but can be used when ventilation is achieved by other methods.
The wedge-shaped product will ensure that the detail is fully insulated in any ventilation scenario.
