In general terms, when considering render solutions for metal frame buildings, the following applies:
Generally this applies to new build projects and can be used within both domestic & commercial schemes.
A project specific specification is available and when installing, close attention is required to the system providers.
Specification is critical to the longevity of the finished render system and particular attention to detailing is needed around openings, corners, movement joints should be evident.
On ventilated systems, the use of board edge closing PVC Beads and insect mesh are integral to the long-term performance.
Frame seal, or APU Beads, are an innovative stop bead for use around windows. The bead includes a self-seal feature, which generally negates the need to apply a silicone seal on completion of render application. Frame seals also incorporate a removable protective strip (the yellow strip seen on the image). This ensures a sharp clean line when complete.
For increased thermal performance within both the refurbishment & new build construction markets: GPD have worked closely with our suppliers for a number of years. Our partners as listed have all carry certified systems for use on metal frame constructions.
The Insulation within an EWI system is often mechanically fixed with a cementitious adhesive. However, as with all industries, manufacturers are striving for improvements to their systems. The fixing methods from STO are a good example.
