Tyvek insulation installation

Tyvek is NOT designed as a product for older homes. What insulation? I have a house about 37 years old It has 16 in studs. Would it be wise to do this. I have heard it would be better to go with spray foam insulation and osb and I have heard that is would be good to put R13 the osb. Would is be advisable in any of these circumstances to go ahead and do the house wrap. I live in the South East part of Alabama. I'm putting on LP smart siding on my 75 year old house that has r13 insulation in the walls and was going to go with a 1in foam bored and typar wrap over the top.

Any suggestions to a diy. I have a 70 by 14 mobile home. Good shape but wanting to update it. I am wanting to put siding on it. The man I spoke to was only going to use tyvek under the siding. I have a wooden outside right now around this home, not vinyl. We are not rich so I need help deciding what to use to do the job. Please advise. Roofing Inverted Roof. Residential Overview.

You may be able to purchase your Tyvek with stud marks printed on the surface at a specified width, which will make it easier to line up with your wall. Position the Tyvek. Begin by placing an edge of Tyvek at one end of the wall, leaving a 6—12 inch 15—30 cm overlap over the corner.

If stud marks are printed on your Tyvek product, line them up with the first stud of your wall. The first roll should be plumb with the bottom edge of the wall. If the wall has not yet been raised, let the Tyvek overhang the bottom edge of the wall and fasten it there with Tyvek tape or sealant.

Unroll and attach the Tyvek. Unroll so the Tyvek is taut, but not so much that it gets stretch marks or tears when fastened. Have a second person secure the Tyvek with a fastener every 6—18 inches cm , over the wall studs. Once the whole roll is attached, use cladding fasteners to attach it permanently. Over wood, gypsum board, and most other wall materials, use large head or washer head nails.

Unless installing over foam sheathing, you may use staples with at least 1 in. Cover doors and windows. Ideally, install Tyvek before installing the doors, windows, or window flashing. However, no matter what stage of construction these areas have reached, you may cover them completely with the Tyvek while first installing. You will make adjustments to these areas once the wall is covered as described below.

Overlap additional rolls of Tyvek to cover the whole wall. If the wall is higher than the width of the Tyvek roll, unroll additional Tyvek higher than the first, moving upward. Overlap the Tyvek rolls by at least 6 inches 30 cm. Make sure to cover the entire wall surface thoroughly, or air and water protection could be significantly reduced.

Use portable scaffolding, not a ladder, when covering Tyvek over high areas. Tyvek rolls are slippery and large, so secure footing is highly recommended when handling them. Cut off excess Tyvek. Use a sharp box cutter or utility knife to remove excess Tyvek from around the wall. Make sure to fasten the Tyvek in place at the end of the wall before cutting, including along unusually shaped areas of the wall such as gables.

Cut out windows in an X shape. Cut a large X from one corner diagonally from one corner to the other. Now fold the flaps to the inside and tack them down. If window flashing or a window apron has already been installed, instead cut out the entire outline of the window. Take care not to cut into the flashing itself, if it has been constructed out of a flexible material. Cut out doors in a capital i shape.

Cut an opening for the doors shaped like a capital "i," including the top and bottom horizontal bars of the letter. Cut from the corners of the door openings to each corner of the "I," with the top and bottom of the "I" located approximately 8 inches Once the cut has been made, fold the Tyvek over the door openings and tack it down on the inside of the framing. Seal the wall wherever necessary. Use Tyvek tape or a sealant product vetted for Tyvek to cover any areas that require additional protection, forming an airtight seal.

Be sure to apply tape or sealant to the following areas: The entire outline window openings except the sill base. Vertical and horizontal seams where Tyvek rolls overlap.

Any tears, puncture marks, or other damage the Tyvek suffered during installation. Larger holes may need a small piece of Tyvek wrap taped over them.

Method 2. Purchase Tyvek FlexWrap. This is a Tyvek product that can easily be stretched to cover the corners of window and door openings. Choose a width, typically 7—9 inches 18—23 cm that can easily cover the sill and provide a couple inches several centimeters of overlap.

While ordinary Tyvek wrap is typically cheaper, it will not provide as durable and effective a water barrier for window sills. Check the slope. The windowsill should be level or sloped slightly outward, to provide adequate drainage. If it is sloped inward or sloped severely in either direction, install a sloped sill pan before continuing. Clean the sill. Wipe the sill and surrounding surfaces with a dry cloth to remove all moisture, grease, dust, and frost from the area. Cut the FlexWrap.

Cut the FlexWrap at least 12 in. This extra space ensures the entire sill will still be covered once the Tyvek FlexWrap is stretched around it and fastened. Apply primer in certain conditions. Primer is only necessary in areas of severe weather conditions, severe cold temperatures, or certain building materials.
