1 The Real Truth About R-value Innovative Insulation Solutions

2 Thermodynamics 101 * Warm air migrates to colder air * Warm air rises - cold air falls * Moisture goes from warm to cold * Moisture goes from more to less * Air goes from a higher pressure to a lower pressure * Gravity acts downward

3 I.R. Imaging Shows the temperature of a specific spot Blue coloring around studs and between fiberglass joints indicates air leakage Darker studs = energy loss Energy loss through and around framing is called Thermal Bridging

4 PROBLEMS with Insulation Thermal Bridging Air Leakage Moisture = PROBLEMS Infrared Imaging: Pictures worth a 1,000 words

5 Air Leakage = Moisture Dark coloring = AIR LEAKAGE & MOISTURE Green horizontal lines & dots = THERMAL BRIDGING Pink, blue, purple = WATER

6 NRC concludes air infiltration accounts for up to 40% of the energy lost in most buildings

7 Rim Joists & Electrical Air leakage is the major cause of moisture problems in walls and roofs - National Research Council Canada

8 Between 50 and 70% of the effective thermal resistance is lost if the system allows vapour transfer from one side of the cavity the other. National Research Council Canada

9 Frozen Moisture NO Cavity Insulation Batt Insulation & Vapour Barrier Batt Insulation - NO Vapour Barrier

10 Frozen to steel Batt insulation compressed against eave strut NO insulation value -3.7C. at eave strut INSIDE the building IMAGINE the energy bill for this building!

11 Joseph Lstiburek, Ph.D., P.Eng., ASHRAE Fellow, is a principal of Building Science Corporation. He is internationally recognized as a foremost authority on energy efficient construction techniques.

13 Batt Insulation & Basements Effective R-value REDUCED by 25% to 65% HIGH ENERGY COSTS & INFERIOR COMFORT ABSORBS MOISTURE - acts like a blotter PROMOTES & SUPPORTS MOLD GROWTH

14 MOLD IN BASEMENTS NASTY STUFF Flooding / moisture & batt insulation promote & support mold growth Sinus and digestive track infections are common Triggers Asthma Can cause DEATH

15 CMHC STUDY Presence of toxic molds in basement walls is common 27 tested, 16 had mold Toxigenic mold found in 15 of these houses Potential impacts beyond the scope of the study Requires attention by health and building science

16 National Energy Code for Buildings (NECB 2011) Mandates a 25% INCREASE in energy efficiency in 2014 Effective R-value / U- value REPLACES labelled R-value 50% INCREASE in building energy efficiency by 2016

17 What is Effective R-Value? Is the ability of REAL WALL assemblies containing wood, steel or concrete framing, drywall, OSB, metal sheathing(s)and insulation to resist the flow of heat in simulated REAL WORLD environments.

18 Oakridge National Laboratory / US Department of Energy states: R-19 batts have an R-value of 13.7 when installed as commonly found in actual walls.

19 ASHRAE (American Society of Heating, Refrigerating and Air-conditioning Engineers) claims the Effective R-Value of a Steel Frame Wall with R-19 Fiberglass Insulation is.only R-7.1

20 National Research Council "In recent years, the focus of building code and regulatory officials, professionals and researchers has shifted towards the performance of the entire wall system. Therefore, it is not sufficient to characterize the wall by its R-value alone, as was the case in the past."

21 "The use of effective R-values when evaluating the thermal resistance of an assembly is preferable to using the nominal/labelled R-value of the insulation alone. "The BEST method of testing is "Full- Scale thermal testing such as ASTM C1363 carried out at a certified laboratory

22 ADVANTAGES CONTINUOUS INSULATION SAVES energy $$$ s o Reduces Thermal Bridging through framing o Reduces air leakage o Increases the comfort of buildings o Reduces the dew point effect o Sustainable protects buildings infrastructure

23 Too BREATHE or NOT To BREATHE the DOUBLE VAPOUR BARRIER SYNDROME

24 NRC Study Double Vapour Barrier The study demonstrated that placing a material with low water-vapour permeance on the outside of an exterior wall does not necessarily increase the potential for condensation within the wall structure as long as sufficient thermal resistance is added outboard of the innermost plane
