Brick Feature Lintels
Custom Made Brick Details
Keyslip Brick Feature Lintels are one piece prefabricated units, manufactured bespoke to order, achieving even the most challenging architectural designs.
Custom Made Brick Details
Keystone provides a technically advanced solution for an extensive range of architectural features including arches, panels, soffits and architectural features. Produced offsite as a one piece prefabricated unit, the patented Keystone system ensures maximum performance thanks to the unique adhesion process.
Keystone receives a consignment of free issuebrick being used onsite. This brick is then tailored to suit the client’s design and fixed to the lintel. The finished Brick Feature Lintel joins seamlessly with the already constructed brickwork. Every Brick Feature Lintel is manufactured bespoke to order, ensuring that each individual unit is customised according to the unique size, shape and aesthetic requirements of the project.
With optional return soffit, centre stone feature and insulation, the builder is able to specify each brick feature requirement through their local builders’ merchant and Keystone’s free Brick Feature Lintel design service.
