The principal construction is in a combination of Sapele and Idigbo, both hardwoods with excellent paint adhesion qualities sourced from sustainable plantations. Durable qualities such as exceptional rigidity, resistance to indentation, shock loads and bending, together with a natural resistance to wood rot and fungal attack, combine to make them the natural choice in framing Town and Country’s buildings.
For non painted conservatories and roof lanterns we recommend either Oak or Iroko construction.
We build to no fixed roof pitches. The pitch is set as appropriate to each design and as the constraints of the site allow.
Our roofs are constructed from delicately moulded 45mm section glazing bars (rafters), hips, valleys, profiled roof plates, and substantial ridge and wall plates.
We offer a range roof ornamentation:- turned timber finials, cast metal finials, cast metal ridge cresting and profiled timber cresting.
Where specified, gable designs can include intricate radial or tracery glazing patterns, all in individually shaped true-divided panes, applied panes, or genuine leaded light panes.
Where specified, feature lanterns (surmounting a conservatory roof), and independent roof lanterns, can include glazed side-frames. The lantern side-frame windows can include intricate radial or tracery glazing patterns, all in individually shaped true-divided panes, applied panes, or genuine leaded light panes.
When required, the roof construction is augmented by internal roof tie bars, cast metal braces and timber encased steel framing.
Recessed electrical conduit channels with flush fitting de-mountable access covers, are incorporated within the underside of roof ridges.
Roof ventilation is provided by ridge mounted opening lights (ventilators), operated either manually by worm-screw openers and an elegant hand pole, or electronically by discreet chain actuated openers. The latter can be specified with variable thermostatic control, rain sensor setting and manual override.
Where ridge mounted opening lights cannot be specified, we offer alternative means of roof ventilation:- mechanical fan housed within a roof pinnacle; passive trickle vents within a roof ridge; top-hung opening windows within lantern side-frames.
Our preferred flat roof construction is of the warm deck type, laid to falls. The construction consists of a carcass of preservative (treated Redwood joists), high-performance foil backed insulation, firring pieces, external quality ply deck and weathering up stand. Mild steel channels and/or I-beams are incorporated where necessary.
The flat roof exterior is prepared to accept a choice of weathering finishes:- heavy gauge aluminium; code-5 lead; three-coat bitumen asphalt.
The flat roof interior is prepared to accept a choice of finishes:- premium grade ply; tongue and grooved match boarding; builders work plasterboard and skimmed plaster finish.
All guttering is in heavy-gauge aluminium.
Glazed roof elevations drain externally into large section ogee-pattern cornice guttering, essentially laid level with discreet internal joints.
Where adjacent to new or existing structures, or where an entablature is specified above the glazed wall-frames (typical of orangeries), the glazed roof elevations drain into substantial aluminium-lined parapet/box guttering, laid to falls and incorporating stepped junctions. Beneath these gutters is the structural timber carcassing (preservative treated Redwood), high performance foil backed insulation. Mild steel bracketing and mild steel channelling support the adjacent roof plate and the gutters themselves. The internal vertical face of this assembly is finished in profiled MDF or recessed moulded panelling. The internal underside of this assembly is finished in premium grade ply or builders work plasterboard and skimmed plaster finish.
Rainwater is discharged by PVC down pipes (aluminium to order), and where appropriate aluminium hoppers.
The wall-frames are constructed from 92mm section rebated jambs, head rails, transoms and a substantial mid-sill and thresholds.
The wall-frames can include a clerestorey – a rise of individually framed windows above a transom over the doors and windows. The arrangement of the clerestorey frame typically follows that of the doors and windows below.
Clerestorey window leaves can be specified openable.
Clerestorey window leaves can include intricate radial or tracery glazing patterns, either in individually shaped true-divided panes, applied panes or genuine leaded light panes.
Doors can be either inward or outward opening and wherever possible are specified to open through 180 degrees.
Opening window leaves can be either top or side-hung outward-opening.
A generous window board (window sill), is fitted internally capping the builders work masonry base.
The wall-frame jambs can be specified to include enhancements:- internal and external pilasters; corbels; stop-chamfered profiles.
The wall frame can be specified to include a substantial profiled entablature. (Typical of orangery designs). The timber topside of the entablature is dressed in code-5 lead.
The wall-frames can be specified to include a substantial timber base, panelled both sides and thermally insulated. (Instead of builders work dwarf walls).
The wall-frames can be specified to include traditional counter-balanced box-sash window frames.
Our single rebated wall-frames are grooved to accept patent draught seals.
Roof:- for glazing units less than 2400mm in length, Dual sealed double-glazing units comprise two leaves of 4mm clear toughened safety glass, a 16mm Argon gas filled cavity, and include Soft-coat Low-emissivity heat reflective coating to the cavity face of the inner leaf. The thermal U-value of roof glazing units is 1:2.
Or
Roof:- for glazing units greater than 2400mm in length, the double-glazing units comprise two leaves of 6mm clear toughened safety glass, a 12mm Argon gas filled cavity, and include Soft-coat Low-emissivity heat reflective coating to the cavity face of the inner leaf. The thermal U-value of roof glazing units is 1:3.
Wall-frames, lantern side-frames and gables with glazing patterns formed in true-divided panes - glazing units are retained with profiled beads internally fixed into 34mm rebated timber glazing bars - have sealed double-glazing units made in individually-shaped panes, comprising two leaves of 4mm clear toughened safety glass (float glass above transom height), a 12mm Argon gas filled cavity, and include Soft-coat Low-emissivity heat reflective coating to the cavity face of the inner leaf. The thermal U-value of these units is 1:3.
Or
Wall-frames and lantern side-frames with glazing patterns formed in applied glazing bars - the glazing units are continuous between a 26mm profiled timber glazing bar internally (without glazing rebate tongues), and corresponding 26mm applied aluminum glazing bar externally. Wall frame glazing units are secured in an aluminium frame inset within each timber door or window leaf. The aluminium inset frame includes integrated weep and breath channels and is supplied pre-finished in two-pack spray finish. The Dual sealed double-glazing units comprising two leaves of 4mm clear toughened safety glass, a 12mm Argon gas filled cavity, and include Soft-coat Low-emissivity heat reflective coating to the cavity face of the inner leaf. The thermal U-value of window and door glazing units is 1:3. Within the glazing unit the glazing pattern is repeated with matching spacers to those forming the unit’s sealed edges.
All timber roof and wall frame components are spray shop prepared to undercoat finish only. Door thresholds are normally mahogany-stained.
