Wet Glazing

Wet Glazing

Many commercial windows are installed after manufacturing with a rubber gasket, also referred to as a dry seal. This dry seal relies on pressure from the window in order to keep moisture out of the window system. Over time, these gaskets shrink and are deteriorated by the weathering process. When the gaskets within the windows no longer function as an effective moisture barrier, we recommend applying wet glazing between the window and the frame. The wet glazing name comes from the fact that the silicone sealant is wet when it comes out of the gun, as opposed to the gasket being installed...

Caulking

Caulking

On masonry buildings, caulk is used at expansion joints, perimeter joints and areas where window frames and stoops meet masonry. Caulk is more able to expand, contract, and move than is mortar making it a better sealant for these applications. An open caulk joint allows unwelcome water into your building and brickwork. It may also allow heated or air-conditioned air to leak out. It may even provide an entrance for unwanted insect pests. Inspection and caulking should be considered as a part of regular maintenance of your building to maintain its value and increase its aesthetic appeal. The...

Transparent Waterproofing

Transparent Waterproofing

Water repellent and waterproofing products are for the protection of vertical or inclined surfaces from the effects of rainwater, whose principal polymers in the dispersion is silane or siloxane. The initial transparent liquid creates either a surface hydrophobic skin or it penetrates into porous of the substrate and then reacts and produces a bonded hydrophobic lining to the pores (the different way of action must be mentioned for each product). Some of them can be added to the finishing product (e.g. into the final surface coating). They are easily applied by brush or spray, diluted in...
