Frequently Asked Questions
What do these sealants do?
They seal the gap around glass and aluminium frames and keep weather out. Pasco 911 is the main product for general glazing perimeters. SA Contractors and Adheseal N70 also suit glass-to-frame joints. They do not carry structural load.
Can I use these for structural glazing?
No. They seal the perimeter gap; they do not carry load. Adheseal N70 is not rated for structural glazing. If the glass must hold weight, use a sealant made and approved for structural glazing.
Which product is right for a window perimeter?
Pasco 911 is the first pick for general glazing and window perimeters. SA Contractors and Adheseal N70 also suit them. Check the product notes for your frame material, substrate, and exposure before you apply.
Can I use a wet-area silicone on a window perimeter?
Wet-area silicones such as Pasco 912 and Bostik 6S are formulated for bathrooms, showers, and kitchens. We keep them in Waterproofing and Tiling. For window and shopfront perimeters, choose a glazing weatherseal.
What surfaces will these stick to?
Glass, aluminium, painted or powder-coated metal, steel, timber, and ceramic come up across these products. Each product has its own approved list. Check the preparation, adhesion, staining, cure, and exposure notes before you apply.
What is the difference between a perimeter seal and structural glazing?
A perimeter seal closes the gap around a frame or panel and keeps water out. Structural glazing holds the glass to the frame under designed load. The two need different sealants. Check the product's structural rating before load-bearing work.
