Thermal Insulation and Other Insulating Methods Thermal Insulation • Exterior Insulation and Finish Systems (EIFS) • Roof Insulation • Heat Loss through Doors and Windows • Building Systems for Improved Insulation
Unit 52 — Thermal Insulation and Other Insulating Methods
Insulation is installed inside and on the surfaces of framed floors, walls, ceilings, and roofs.
Unit 52 — Thermal Insulation and Other Insulating Methods
Insulation R values are based on the climatic conditions of the area. Note the difference between the recommended R values for western and northeastern areas.
Unit 52 — Thermal Insulation and Other Insulating Methods
Various insulation materials provide differing R values.
Unit 52 — Thermal Insulation and Other Insulating Methods
Increased insulation thicknesses provide greater R values. For example, 3.5″ of fiberglass insulation has an R value of 11.
Unit 52 — Thermal Insulation and Other Insulating Methods
A pressurized hose is used to blow loose fill insulation between the ceiling joists.
Unit 52 — Thermal Insulation and Other Insulating Methods
A plywood rake is convenient to spread and level off loose fill insulation between ceiling joists.
Unit 52 — Thermal Insulation and Other Insulating Methods
Loose fill insulation can be blown between the studs into wall cavities.
Unit 52 — Thermal Insulation and Other Insulating Methods
In the blown-in-blanket system, loose fill insulation is blown into a bag made of retention fabric, which has been fastened to the studs.
Unit 52 — Thermal Insulation and Other Insulating Methods
Flexible batt and blanket insulation differ only in length.
Unit 52 — Thermal Insulation and Other Insulating Methods
Blanket and batt insulation must be properly installed for maximum energy savings.
Unit 52 — Thermal Insulation and Other Insulating Methods
A thin layer of foamedin-place insulation is sprayed on a surface. The foam then expands to fill the wall cavity.
Unit 52 — Thermal Insulation and Other Insulating Methods
Heat loss occurs through full-basement, crawl-space, and slab-at-grade foundations.
Unit 52 — Thermal Insulation and Other Insulating Methods
Rigid foam insulation can be applied to the exterior or interior of concrete foundation walls.
Unit 52 — Thermal Insulation and Other Insulating Methods
Metal fasteners may be used to attach rigid foam insulation to concrete walls. Note the metal channel cap at the top of the insulation to prevent water from getting behind the insulation.
Unit 52 — Thermal Insulation and Other Insulating Methods
For a slab-at-grade foundation, rigid foam insulation is placed along the outside of the foundation wall or placed beneath and between the wall and slab.
Unit 52 — Thermal Insulation and Other Insulating Methods
Rigid foam insulation is often placed behind siding or masonry veneer.
Unit 52 — Thermal Insulation and Other Insulating Methods
Exterior insulation and finish systems (EIFS) provide an excellent waterproof insulation system.
Unit 52 — Thermal Insulation and Other Insulating Methods
Rigid foam insulation is applied to the upper surfaces of the rafters. Tiling and counter battens and roofing felt are installed prior to installing roofing tile.
Unit 52 — Thermal Insulation and Other Insulating Methods
Shingles or shakes can be directly fastened to the cover board.
Unit 52 — Thermal Insulation and Other Insulating Methods
Rigid foam insulation is installed below the roofing felt plies of a built-up roof. The insulation may be tapered to provide a sloped roof.
Unit 52 — Thermal Insulation and Other Insulating Methods
A caulking gun with cartridge is used to apply caulk between a window frame and concrete block wall.
Unit 52 — Thermal Insulation and Other Insulating Methods
Different types of weatherstripping may be used around doors and windows.
Unit 52 — Thermal Insulation and Other Insulating Methods
Door bottoms must be sealed to prevent air infiltration.
Unit 52 — Thermal Insulation and Other Insulating Methods
A steel-clad, foaminsulated exterior door allows little heat transmission. Note the weatherstripping and threshold that have been installed.
Unit 52 — Thermal Insulation and Other Insulating Methods
Storm doors are hung on the outside of the door frame. The glass pane can be replaced with a screen for airflow in warmer months.
Unit 52 — Thermal Insulation and Other Insulating Methods
This double-glazed window has special 1/2″ sealed insulated glass and an air space to provide a highly insulated unit.
Unit 52 — Thermal Insulation and Other Insulating Methods
Gas-filled windows have greater U values than traditional multiple-pane windows.
Unit 52 — Thermal Insulation and Other Insulating Methods
Energy efficiency is gained by using a variety of insulation techniques and materials.
