THEORY BOOKS COVERED

11/12/08

During this course we have studied the following books,
- Install and replace windows
- Explosive powere tools
- Fixing out
- Claddings and linings.
- Health and Safety for Carpenters 2

INSTALL AND REPLACE WINDOWS

This book covers the different types of buildings we may face in the building industry. eg brick, stone, concrete, timber, brick venere and how these may affect how we do our job. The book covered venere buildings and how they affect how we install doors and windows. we covered the diferent wall ties, roof ties and hinges used and how and where they are used.

EXPLOSIVE POWER TOOLS

This book is explained in one of my ealier blogs

FIXING OUT

The fixing out theory book covers all the different types of mouldings that are commonly used in the carpentry industry. from architraves to skirting, coving, scotia, and all the different profiles they come in and where they go. This book continues on to explain how we are to calculate lengths of mouldings and how to invoice clients the quantity and cost.

CLADDINGS AND LININGS

This book covers the cladding side of our course. It covers the diferent materials that are available, the fixings that should be used for them, and the diferent flashings, clips and joiners that are available for each product. It covers sarking and water proofing of cladding buildings and explains the starndards of using different products. This book also covers the material calculations of cladding and the cost invoicing.

HEALTH AND SAFETY FOR CARPENTERS 2

We covered this health and safety book and studied for the test. It covered workplace housekeeping, firefighting,safety signs, hazardous, materials, noise, and emergencies. we did the test on this which i recieved 98%.

Controls; gloves, careful handling

Install corner mouldings-
Hazards; drop saws, routers
Controls: use of ppe, careful handling

Practical Cladding Assesment

Install Sisolation
The first thing we will have to do is to put our sisolation on the walls we need to clad. Making sure our laps are correct and will maximise weatherproofing.
Tools- knife, clouts

Install Flashings
After our sisolation is on, we will need to install our flashings down the external and internal coners of our walls.
Tools tin snips, clouts

Install corner moulds
After our Flashing are installed, we can put our corner moulds in place, running vertically from 50mm below the bottom of the plate and hard up to the top of the wall. The internal mould should be around 30 x 30mm and the external somewhere around 45 x 45mm with a 12x 12mm rebate out of one corner so that it can fit around the corner of the wall.
Tools- drop saw, router, bench saw, nails/ screws.

Install weatherboards
After the corner moulds are in place, we will then be able to start cladding. starting by putting a fillet along the bottom so that the bottom board kicks out like the rest of the boards, we can start cladding from the bottom up. making sure the boards are level and fit nice and tight we can nail them off just above where the board below would be. We will need to watch for our 25mm lap, to ensure that it stays consistant.
Tools drop saw, hammer, clouts/nails, ruler

PROJECT CONSTRUCTION PLAN

2/12/08

Project: Window installation

CONSTRUCTION STEPS, HOW IT HAPPENS, TOOLS AND EQUIPMENT

Placing raw frame into vice.
We were given a raw timber frame with a window in it.We fixed the frames in
our vices in order to install our window sashes and clad around them
Tools- vice

Putting sisolation on.
After our frames are secured in the vice, we put our sisolation (brown Building paper) on. making sure our laps are going the right way.
Tools-knife, staples

Installing window
Put window into the frame to figure out where our packers need to go to make it level and plum, with a consistant spacing all the way around. Once the window is packed in tight, it can then be
nailed into the wall frame through the side of the sash, making sure ure nails go through the packers to prevent twisting the window sash.
Tools- drop saw, hammer, level

Install flashing
Install our flashings above the window to ensure that it is kept water tight, knowing that if we run flashings down the sides aswell it will increase the water proofing of the window.
Tools- tin snips.

Install cladding
After our flashings go in we need to install our cladding around our window. Starting from the bottom of our frame, upwards, we will clad our wall ensuring that our boards are level, and the same hieght from the bottom on each side.
Tools- drop saw, nails, hammer, tape measure

Install gyprock
Once we finish cladding our walls we will turn our focus on the inside of the frame and window.
the first step here is to put up our gyprock for our internall cladding.
Tools- glue, nails/ screws, knife. straight edge

Install window sill nosing
After our gyprock goes on we can then put our sill nosing in. We will have to measure our check outs for our horn nosing, and measure our Architraves to calculate how long our horns need to be. we will then cut out for our horns using a drop saw, band saw and we will put our bullnose profile on them with a router.
Tools- drop saw, band saw, router

Install jamb packers
After out sill nosing goes in, there will be a gap between the window sash and the inside edge of the gyprock. this will need to be covered up with some Jamb packers. the gap that is left between the edge of the gyprock and the frame will be covered up with the architraves next.
Tools- drop saw, rule, brad gun

Install architraves
After our Jamb packers go in we are then eble put our Architraves around the window. Remembering our 10mm margin, cutting our mitres in the top corners, we need to fit the architraves as neat as possible making sure we fit them down hard on our horns.
Tools- Mitre saw, brad gun, rule.

Install Scotia
The last step will be to install the scotia under the sill nosing.
Tools- mitre saw, brad gun
