Glass facade weather sealing
Building’s exterior structure must be protected against the various weather conditions such as UV rays, rain, wind, snow, etc. Also, it is important to protect the building’s structure against various other factors such as chemical and mechanical loads that may eventually cause damage to the building. Glass facades are especially complicated as the sealant used for the glass facade joints must be extra durable, compatible non-porous materials and totally weatherproof.
Backing the joint between glass elements
To ensure the proper size and shape of sealant in the joint and to avoid triple adhesion, a backer rod must be used.
Backer Rod PE 450 – round backer rod with closed cell structure. Highly flexible and compressible for easy installation.
Sealing joints between glass elements
For long-lasting, weatherproof joints, a neutral curing silicone with high movement capability must be used to compensate for deformation in the joint without losing elasticity or adhesion.
Glazing Silicone 330 – a high-quality neutral alkoxy silicone sealant with excellent adhesive properties and low modulus. Forms a flexible rubber seal with many porous and non-porous materials.
An alternative product is Building Silicone 322 – a multipurpose neutral silicone sealant with high movement capability and excellent adhesive properties. Forms a mould-proof and ageing-resistant, flexible, silicone rubber seal.
