Also known as 'glass joiners' or 'glazing connectors' this one-part muntin bar is used to connect separate units of glass or polycarbonate sheets in conservatory roofs.

Features & Benefits

• Strong aluminium extrusion
• Thermal break stops condensation
• Internally ribbed to trap sealant
• Secure and reliable joint
• Hardwearing powdercoated finish
• For 24mm glass or 25mm polycarbonate
• Simple H-section design
• Fit and forget reassurance

Manufacturing limitations of glass and how it is being used can can restrict the maximum length of a unit. Muntin bars are used to join more than one unit and therefore span a longer distance.

Create a reliable seal

• Ensure that all surfaces to be joined, including the inner faces of the H-section, are clean and free from dust.
• Apply a bead of sealant* to the leading edge of both inner faces of the H-section.
• Bring two edges flush together and carefully push the H-section onto the glazing or roof vent. The sealant will be drawn under the H-section and create a seal between the two. More sealant can be added if required.
• Carefully remove any surplus sealant.
• Apply a neat bead of sealant along the H-section where it meets the outside face of glazing or roof vent. Then do the same with the inside face.
• Repeat the above for the second side of the joint.

* Use a sealant that is compatible with your glazing material. We recommend a neutral cure sealant, such as GB-Pro.
