Triple glazing adds and improves the thermal efficiency, giving your doors a better U-value.
U-values measure how effective a material is as an insulator. The lower the U-value, the better the heat insulation.
We normally supply all our doors and windows in fixed standard sizes. However, a bespoke service is available - please provide further information including dimensions via the Contact Us page, or call our sales team.

No treatment prior to installation is required on prefinished Vufold doors, however, regular maintenance is required. We have a full range of kits to help you maintain your timber doors. Please visit our maintenance section for more details on these products.
Our internal oak doors are supplied unfinished, as well as the Elite Unfinished external bifold door range, which will need treating before installation.
With top-hung / top roller systems, it is vital to fix through the aluminium track, timber frame head and lintel. Vufold doors are top-hung (except our aluminium Status and Supreme ranges, which are bottom-hung), so all the weight is supported from the aluminium top channel and the head of the timber frame, hence the importance of a secure fixing into the lintel, to enable the system to work correctly.
For fixing into RSJ / ‘I’ lintel use nuts and bolts (not provided). Direct frame fixings are provided to fix to a steel lintel.
If in any doubt consult a structural engineer.
FRAME Jamb: normally installed 5-10mm back from face of building, with cill on brick course.
