4. Walls and Windows
4.1 Stud Work
I installed stud work (2 x 3in timbers) between the upright posts to create the structure to which the inner and outer covering can be affixed.
There are several considerations at this point:
- Diagonal elements introduced into the stud work help prevent shearing and generally stiffen up the structure.
- Studs at the base of internal walls and at the sides of corner posts ensure there are fixing points for walling material inside
- Studs can be spaced horizontally and vertically to match up with internal sheet materials making fixing easier and reducing the amount of cuts needed (e.g. 4 x 8 ft ply sheet shown as blue rectangle on diagram above)
4.2 Gable End & Panoramic Window
The gable end of the roof was formed out of stud work attached to the wall plate. Space was left for the small gable window. Temporary diagonal bracing using added to prevent it being pushed over by the wind.
Studwork in the end wall was installed to create openings for the panoramic window. The studs create the mullions, and the double glazed units will simply sit in the gap with beading holding them in place behind and in front of them. The only sophisticated element to this part of the design was a standard window cill which was cut round the central post and sat on top of the horizontal studs shown above.
At this stage I sealed all gaps with mastic and painted the timber with a water repellant paint, knowing that once glazing and beading go in some of the timber will never get another coat. I am pleased with how well these windows have faired: no leaks, no blown units. Way cheaper than buying commercial units, and with structural (load bearing) mullions!
Hardwood beading was fixed on the inside for the double glazed units to be bedded using glazing mastic and spacers. External beads were then fitted to hold the glazing in place. The bottom bead was raised on spacers to ensure the bottom of the unit was ‘drained and vented’ so that the bottom of the unit would never sit in a puddle of trapped water.
