Joint fillers and sealers are used to seal, set and bond joints in various building elements, including windows, floors, doors, panels, cladding and glazing. They provide flexibility in construction and movement joints, and can be used in external environments for paving and bridge joints. Read More

The seals come in formats to suit the application, be it preformed sealants, mastics, foams, putties or liquids.

Intumescent sealants help prevent the spread of fire through a building. Other fillers and seals can have waterproofing, humidity resistant, permeable, flexible, UV stabilised or low shrinkage properties.

Movement and expansion joints , mortars and adhesives can be found in separate sections on this site.
