Conservatory Joinery

We design and build our side structures utilising the very best materials to reflect the design criteria. Great consideration and care is taken to incorporate the correct mouldings and detailing to echo the period and architectural characteristics of the conservatory.

Our National Trust Conservatories are predominantly manufactured from Douglas Fir, which is without doubt, one of the hardest, strongest and most durable timbers available. Contrary to popular belief that hardwoods are superior to softwoods, Douglas Fir is a more superior timber to use in construction than many readily available hardwoods. Douglas Fir is a stable timber which seasons well, dries evenly and remains straight and true with negligible checking or distortion. It also has the characteristic of having excellent longevity, even in its natural state.

Interesting facts:

  • Balsa wood – one of the softest, weakest and least durable timbers available, is actually a hardwood.
  • The 70-metres tall flagpole at Kew Gardens is made from Douglas Fir - and is thought to be 370 years old.

Vale remains committed to an environmentally responsible policy and the timber used in a National Trust Conservatory is purchased from sustainable sources and in addition, Vale has a Chain of Custody policy and is audited annually under the FSC & PEFC scheme.

At Vale, we also subject our cut timbers to pressure treatment which impregnates the timber with an organic solvent and gives additional protection against rot and fungal attack. This process ensures absolute longevity of your timber. To ensure the very best standards are maintained, this is carried out in-house under strict quality control procedures.

Windows & Doors

All doors and windows are constructed in the traditional proven way with mortice & tenon joints. Traditional timber window detail is created with a traditional true-divided light construction, achieved with a 26mm glazing style housing individual double glazed units.

As standard, due to the weight of the joinery and glass most of our windows are top hung excluding cragside design and each is fitted with two 250mm casement stays, one incorporating a security locking nut.

Doors are usually outward opening, fitted with a suited 5 lever mortice lock. In addition all doors are fitted with shoot bolts top and bottom with the master door bolts having a locking mechanism for additional security. Each door is hung on decorative finial projection hinges.

All our doors and windows are fitted with storm proof seals and whilst all ironmongery is generally specified in un-lacquered brass – chrome and bronze are also available.
