Joinery Specification

Here at David Salisbury, we source all of the timber used in our orangeries and kitchens from sustainable sources and responsibly managed forests.

We only use premium quality timber which is specifically selected for a combination of strength, durability, machining properties and an ability to accept a wide range of finishes.

Orangery WINDOWS & DOORS

We offer 3 framing systems for doors & casement windows with projecting casements or flush closing options these are 68mm or 93mm thick respectively with a heavier framing of 109mm frame available to allow for triple glazing.

All frames have three different moulding options, as do casements which can be mixed and matched as required.

In addition we have 4 vertical sliding sash systems. Weighted & spring balanced, both in two different frame thicknesses. As with casement windows there are several options on sash moulds.

TYPICAL PHYSICAL PROPERTIES

Typical physical properties are:

• Moisture content (kiln dried) 12-14%.
• Strength (Young’s Modulus is a measure of elasticity; the higher the value the greater the strength) – 8000.
• Conformance – Class 1 hardwood to BS1186*.
• Roof wind and snow loading – satisfies BS6399*.

Using a matrix of sizes underwritten by our structural engineer, every roof made by David Salisbury is designed to meet current British standards. Structural tie-bars will be included where necessary and if Building Regulation approval is required full structural calculations will be supplied.

Flat roof areas and ridges are finished with either a single ply membrane or lead as required by the client.
