sequentially
Insulating Walls
6. • Before you begin your project, it is crucial that you
have the correct materials.
• Your budget will have a great impact in determining
what material you use.
Obtaining the proper materials for the job
• We will look at various insulation and drywall options
7. • Insulation comes in a variety of options. There is
traditional rolled or batt insulation, blown insulation,
rigid insulation, liquid insulation, and loose filled.
Obtaining the proper materials for the job
• You must also decide what type of rolled or pre cut
insulation you will use.
• For this project we will concentrate on rolled or pre
cut insulation.
8. • You should take a look at the R-value of the insulation
and determine which would be best for your project.
Obtaining the proper materials for the job
• An R value measures how well building insulation
materials, such as fiberglass insulation, resist heat.
• The higher the R-value, the greater the insulation.
Insulation with a higher R-value will perform better
than insulation with a lower rating insulation
9. • 2 inch x 4 inch walls can hold R-13 or R-15 batts.
2 inch x 6 inch walls can use R-19 or R-21 products.
Obtaining the proper materials for the job
• For climates that are humid and hot an R value of 15
or R-21 should be used.
• The choice of going with rolled or batt depends on
the project. Many older homes have unique room
dimensions. Batts that are pre cut in various widths
can help reduce time.
10. Obtaining the proper materials for the job
Rolled Pre cut
• Here are examples of rolled and pre cut insulation
11. Obtaining the proper materials for the job
• Drywall comes in sheets. The most common size
is 4 x 8 feet.
• Larger sheets are available to use so that you can
reduce the number of seams.
• We now take a look at drywall.
• If the room you are remodeling is larger than usual,
the larger sheets will be helpful.
12. Obtaining the proper materials for the job
• Square-edged
• Moisture-resistant
• Here are the various types of drywall.
• Foil-backed
• Taper-edged
• Fire-resistant
• Soundproof
• Abuse-resistant
13. Obtaining the proper materials for the job
• 3/8 inch and 1/2 inch being the most common.
• You must also choose how thick you want
the drywall to be.
• For this project, we will use ½ inch drywall.
17. Preparing to insulate
• To begin, measure the width between wall studs.
• Make sure you also measure the height of the wall.
• Write down measurements on paper
18. Preparing to insulate
• Take insulation and get one batt
• Measure batt and mark off measurement
with a pen.
• With a box cutter, proceed to cut horizontally.
19. Preparing to insulate
• Place batt in between studs.
• Make sure that batt reaches to about ¼ inch
from floor
• Gently pat batt to insure that there are no
air gaps
20. • Locate tabs on both sides of drywall.
• Pull tabs out so that they can be fastened
to drywall
• With staple gun, gently staple tab to stud
Preparing to insulate
• Do not pull to hard as insulation may tear
• Fasten tab to the side of the stud
• Do not fasten to top of stud
21. Drywall
• We will now look at two forms of drywall
• We will go over characteristics of each one
23. Installing Drywall
• We will now look at installing drywall
• We will go over the procedure on how to hang drywall
24. Installing Drywall
• Once you have measured you’re the dimensions of the area
you will cover, you must determine which drywall type is
best.
• If the area is inside the home or a building, traditional
drywall will be best.
• If the area will be exposed to moisture, such as a bathroom,
green drywall will be best.
25. Installing Drywall
• When working with drywall, you want to use as few as possible
• The reason behind this is because you want the least
amount of seams possible.
• This will ensure less work later on and the wall will have
a smoother appearance.
26. Installing Drywall
• Make sure you have the tools necessary for installation
• Sheets of drywall
• Box Cutter
• Drywall sander
• Drywall jack• Drywall screws
• Drill
27. Installing Drywall
• Once you have determined how many sheets you will need
it is best to have them in the within reach
• Make sure than you fasten properly to avoid cracking or falling
• Begin to hang drywall from the top down
29. Installing Drywall
• After installing drywall, inspect for unevenness
• Many times a stud may be warped or crooked
• If you have an area that is too uneven, you may have
to remove the sheet and take care of the stud.
• If everything is alright, then you are ready to begin the next
phase which would be tape and float.
