New glass sealing process

Endurance Doors recently invested in a new glass sealing process for its solid timber core composite doors, which helps to eliminate water ingress.

Water ingress is an issue that has hampered the composite door sector in the past and it has been several years since Endurance incorporated a Moisture Barrier Systems (MBS) to the bottom of its door slabs.

The first stage in the process involves the bonding of the two inner glazing cassettes and glass unit to the Endurance door slab, using the pre-inserted black double-sided tape. The new additional stage in this process introduces the wet sealing of the external cassettes, with the application of a silicone bead to the inner and outer channels of the external cassette, before they are both pushed together on the slab, with any excess wiped clean prior to being screwed together.

Stephen Nadin, managing director of Endurance Doors, said: “With the recent heavy rainfall during the latter three months of the year, we’ve heard of a number of composite door installations that have been subject to water ingress to the foot of the door slab and also into the glazing cassettes. The results have been graphic and represent the risk of installing composite doors where manufacturers don’t take water ingress seriously.”
