Foam Board Insulation for Long Island Homes

Foam board is a rigid board substrate that is ideal for places where a firm surface, walkable or otherwise, or a surface that can be cut is desired, including attic access hatches, storage platforms, kneewalls, and localities around air handling units. It offers uniform insulating capacity, unlike some loose fill materials, which settle over time.

We will use foam board where it can be used selectively, and is more rigid and useful for the purpose of being cut to size, than cellulose or spray foam.

How it works

Where Foam Board Insulation Works Best

Foam board comes in rigid panels that can be cut to fit specific spaces, then secured in place. Because it holds its shape, it's often used in areas that need to remain accessible or walkable, such as attic hatches, storage platforms built over insulation, and kneewalls in finished attic spaces.

It is also installed around unconditioned air-handling equipment and ductwork to provide a firm surface on which the insulation layer can rest to prevent its being compressed or disturbed. 

Warning signs

Where Foam Board Insulation Delivers the Best Results 

Foam board tends to make sense in specific spots rather than as coverage across an entire attic floor.

Areas around air-handling equipment

Storage platforms built over existing insulation

Basement rim joists in some applications

Kneewalls in finished attic spaces

Spaces needing a walkable or trimmable insulated surface

Our process

What Foam Board Insulation Can Do for Your Home



Circle Step
01

Area evaluation

We identify where a rigid, cut-to-fit material would perform better than cellulose or spray foam for that specific location.

Circle Step
02

Measuring and cutting

The foam board panels are then measured and cut to fit the access point, kneewall or platform being insulated.

Circle Step
03

Installation

Panels are secured in place and seams are sealed as needed to reduce air movement around the installed foam board.

Circle Step
04

Review

A walkthrough is conducted to review the completed work and any other insulation/air-sealing opportunities are identified. 


Benefits

Key Benefits of Foam Board Insulation

Consistent, Non-Settling Coverage

Foam board can also keep maintaining insulating properties over time without settling, as can some loose-fill materials.

Walkable and Trimmable

Foam board can be used to provide light load-bearing for platforms on attics, and can be cut to fit in odd spaces and access holes.

Useful at Access Points

It is an easy-to-use solution for areas with a hatch in the attic or kneewalls that must be accessible to save on energy loss and still provide insulation.

Protective Layer for Equipment Areas

Foam board can help protect insulation and ductwork in unconditioned spaces near air-handling equipment.
