Our Process

Below is a summary of a typical project broken down, however this is not conclusive as all jobs are invariably different and be will dealt with on their individual requirements.

Preparation

All projects start off with careful frame preparation, making sure that the surfaces are true and within an acceptable tolerance to fit the glass units. The work is completed by hand using traditional hand tools, mainly planes. Special care is taken to ensure door posts are within an acceptable tolerance to avoid any potential distortion of door and window frames.

Fitting the covering boards

Once we are happy that the frame is ready for glazing we start by fitting air dried larch packers, these are fastened with A2 stainless steel screws to the oak frame. The covering boards we use are prime air dried oak which can have a fine sawn or planed finish depending on the preference of the client. 

These are rebated, cut, pre-drilled and then temporarily fitted in place on the frame. We use stainless or copper flashings at the intersections; these will have been pre-formed to give a nice sharp finish. When we are happy with the covering boards they are removed and prepped ready to apply the EPDM tape. With this complete we lift the IGU's in place and refasten the covering boards.

Finishing

All the fastenings are counter-bored and oak pellets are used to fill the holes, each being glued with waterproof adhesive and cleaned up flush. Once the work has been completed the site is cleaned and all waste removed.

SPECIFICATION

Covering boards

All our oak covering boards are machined from prime air dried European oak which can be finished with either a sawn face or planed to a minimum thickness 33mm. We double screw all covering boards wider than 125mm at no more than 400mm centres. All screws are counter bored and pelleted. All corners are rebated.

Packing Timber

33mm thick larch, screw fastened at a maximum of 400mm centres.

Fastenings

Spax T drive A2 stainless steel countersunk screws used throughout. Covering boards are fastened with 100mm x 6mm countersunk screws and the packers are fastened with 70mm x 6mm countersunk screws.

EPDM Tape

Top quality EPDM tape used throughout.

Flashings

Stainless steel or copper flashings used at intersections with ground and first floor units. All flashings are pre-formed. Fit flashings at the floor plate to suit.

Insulated Glazing Units (IGUs)

28mm overall thickness
6mm low iron, toughened (outer)
16mm argon with black warm edge spacer
6mm low iron with low E coating, toughened

Depending on unit size the glass thickness may need to be increased.

DOORS, WINDOWS AND JOINERY

As part of our glazing service we are able to supply doors and windows that are designed to be incorporated within the face glazing with rebated frames. We can also make up sub-frames for aluminium and composite doors and windows.
