Title 24 Envelope Highlights

Envelope HighlightsMandatory Measures §150.0There are several new thresholds for mandatory enveloperequirements including:• Ceiling/Roof insulation maximum = 0.043 U-factor (R-22 wood framing)

Prescriptive High Performance Walls §150.1In Climate Zones 1-5 & 8-16, above grade framed wallassemblies must not exceed a maximum U-factor of 0.051:• 2x6 @ 16” OC framing—R19 cavity + R5 continuous• 2x4 @ 16” OC framing—R15 cavity + R8 continuousIn Climate Zones 6 & 7, the maximum U-Factor is 0.065

Prescriptive High Performance Attics §150.1There are three options that may be used to comply:• Option A: Ducts and air handler may be locatedin the attic– Install attic radiant barrier (Zones 2-15)– Install R-38 insulation at ceiling (R-30 in zones 3 & 5-7)– Install continuous roof deck insulation (Zones 4 & 8-16)• R-6 with air space above insulation/ R-8with no space

RDeck Installation

Continuous Insulation for Walls “Half- SIPS” insulated wall panel- ThermaBase-CI

ThermaBase-CIFastening Chart for ThermaBase

Structural Bracing• Install continuously across the wall to

simplify design

• Install as a braced wall panel with Thermasheath-3 to optimize design costs

• Eliminates the need for heavy OSB sheathing

• Decrease time and costs associated with materials and labor

Continuous Insulation (c.i.)

• Polyiso has the highest R/inch of any foam plastic insulation

• Eliminates thermal bridging

• Allows you to meet or exceed energy code requirements

• Lowers energy consumption and energy bills

Air Barrier• Prevent air infiltration

• Keeps the home comfortable

• Makes your HVAC systems run more efficient

Water Barrier• Eliminates the need for house wrap or felt

• Resists water intrusion and moisture migration

• Defends against the growth of mold and mildew

R-SEAL Construction Tape

Recommended Zones

Installation Step 1: Measuring and Cutting

Wind Zones: • Use prescriptively in wind zones

≤110 mph • Use in higher wind zones requires

an engineered design

Wind Loading Seismic Loading

Seismic Zones: • Use prescriptively in seismic

design categories/regions − A, B and C− Do, D1 and D2

NOTE: With ½” gypsum applied to interior. Adjustment factor needed when there is no interior gypsum. Refer to TER 1207-01 for full details.

Recommended Usage

• Residential applications with numerous veneers: brick, stone, stucco, siding (wood, vinyl, aluminum), cement board, etc.

• Exterior wood frame walls

• Use as intermittent bracing with Thermasheath-3

• Use as continuous structural insulated sheathing

• With taped joints and other standard construction practices for sealing, achieve air barrier and water-resistive barrier (WRB)

• Do NOT install panels unless temperature is above 20˚F

• Wear eye protection when using power cutting tools

• Safety mask may be necessary while cutting this product due to nuisance dust

• Measure and mark panels for cutting using: − Chalk line

− Straight edge and marker

• Cut boards on a level, durable surface, using a circular saw

• Notes for cutting:− Do not shave, rasp or carve facers off any panels

− Rmax does not recommend scoring or cutting the back side of a panel allowing the board to

conform to framing regulations

− Rmax does not recommend the cutting or trimming of panels with the “score and snap” method

− Polyiso will not break cleanly or evenly – recommend using a sharp, fine-toothed saw

Installation - Step 1: Measuring and Cutting

Installation - Step 2: Installing Panels

• The Rmax logo must face out

• Install panels vertically with the length dimension of the panels parallel to the

framing behind

• Install directly over studs, refer to TER No. 1207-01 for framing requirements

Note: All perimeter edges must be backed and fastened to a framing member.

Installation - Step 2: Installing Panels (continued)

− Use Thermasheath-SI continuously

OR

− Use Thermasheath-SI in areas where

bracing is required per code

− Integrate remaining wall with Rmax

Thermasheath-3 insulation

R-SEAL Construction Tape

Installation - Step 3: Fastening• Fasten boards using approved staples every 3” along

perimeter and every 6” in the fields of the boards

• Fasteners must be placed not less than 3/8” (9.5 mm)

from sheathing edges

• Staples shall be a minimum 16 gauge, 1/2” or 1” crown,

at least 1 1/4” leg and penetrate a minimum of 1” into the

stud

• Nails shall be minimum 0.113” x 2 3/8” and penetrate a

minimum of 1 ¼ inch into the stud.

• Sheathing joints must be butted at framing members and

a single row of fasteners must be applied to each panel

edge into the stud behind

NOTE: Do not tack sheathing products to framing, but fasten each panel completely once fastening begins.

Note: Maintain a minimum 1” penetration into wood studs, fasteners may be countersunk.

DO NOT TACK FASTEN COMPLETELY

FIRST

FASTEN EVERY 3”ALONG PERIMETER

FASTEN EVERY6” IN THE FIELD

Installation - Step 4: Taping

• To achieve a WRB:

− Tape all joints & protrusions with

3” R-SEAL Construction Tape

− Center the tape over the joints to cover fastener penetrations

− Tape must be installed in temperatures between -25°F to 135°F

− Apply in shingle like fashion starting from bottom up

NOTE: Fasteners in the field of the board do not need to be taped to achieve WRB.
