Implications of Building Fenestration on U-Value
The initial review of the building demonstrated a very regular repetition of windows with colonades of brick slip and aluminium cladding panels. The locating of Cavity Barriers and Slab Edge Fire Stopping within the crucifix details added to the complexity of the challenge faced when assessing the building u-value. The quantum of metal required within the construction in terms of bracket and rail was significantly more than would typically be required in terms of structural support simply down to the fenestration detailing, this had a significant impact on the U-value, affecting the insulation thickness and the bracketry depth, therefore the stand-off of the cladding to the building. In order to overcome this, SCF have reviewed a number of different options for the builidng;
- Utilising bracket and rail which spans slab to slab
- Utilising bracket and rail which uses a more optimal chi gasket, improving the thermal loss
- Utilising a thermal bridge free bracket
- Utilising alternative brick slip products which are mortar adhered directly to insulation with no bracket and rail requirement
Each has its own merits and variously there are drawbacks to each of the product.
