Always a company that invests in outstanding product performance, Endurance Doors have recently invested in a new glass sealing process to their solid timber core composite doors, which has had a positive effect on helping to eliminate customer concerns over water ingress.

Water ingress in composite doors has hampered the composite door sector in the past and it has been several years since Endurance incorporated a unique Moisture Barrier Systems (MBS) to the bottom of their door slabs. But the recent introduction of a new glass sealing process adds further credence to the claim that Endurance Doors have become the #KingOfComposites.

The first stage in the glass sealing 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 important 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, excess then wiped clean prior to being screwed together.

This additional application of silicone has had a positive effect on the number of customer concerns. All of the operational efforts over the last 18 months in terms of adopting a quality culture and this and other new processes, have seen customer product issues nearly completely eliminated.

Stephen Nadin, Managing Director of Endurance Doors commented: ‘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.’
