Blanket Insulation

Versatile and easy-to-use, rolls are usually the same width as the space between joists or rafters.

Cellulose

Cellulose requires a blower, which can be rented, and is ideal for small spaces.

Pipe Insulation

Use this in a cold roof to prevent pipes from freezing, which may cause costly leaks and damage.

Framefoil

This material retards heat transfer by reflecting heat back to its source and by trapping air in its multiple layers.

6 mil Polyethylene

This waterproof, clear polythene membrane is suitable for use below new concrete or wood floors.

4 mil Polyethylene

This polythene sheet plastic is used to stop water vapor from penetrating ceilings and sometimes walls.

Pipe Lagging

Use pipe lagging to wrap around attic water pipes.

Flanking Tape

Use flanking tape to cover gaps along edges when soundproofing.

Acoustic Underlayment

Used under flooring instead of regular underlayment, this helps to improve a room’s sound insulation.

Polystyrene Board

This rigid board is installed below floors but also in roofs for insulation. Adjacent edges interlock using a tongue-and-groove design.

Extruded Polystyrene Board

This rigid board is used to insulate concrete floors. It is also bonded under flooring sheets to make storage decking in an attic.

Rigid Board Insulation

This comes in panels and provides a high level of insulation. It is more expensive than blanket or loose-fill insulation.

Acoustic Mat

Used in a continuous layer below flooring, this densely packed material reduces the effects of airborne noise.

Acoustic Slab

This dense soundproofing material is sold in slabs. It can be laid below floors, above ceilings, and within walls.
