The Spray Foam Guys

Spray foam insulation is an alternative to traditional building insulation, and due to its fantastic versatility, can be used on any areas of your property, including your roof, loft, walls and floors. Using spray foam assists in retaining the warmth and heat within your home, therefore reducing energy costs with less heat being wasted and lost.

Spray Foam Benefits

Up to 40 percent of a building’s energy is lost due to air infiltration. Gaps and air leaks allow expensive heating and air conditioning to go to waste, and needlessly increase energy bills. An alternative to traditional cellulose and fiberglass insulation, spray foam insulation resists heat transfer and insulates and seals gaps.

Why use Spray Foam?

At Red Letter Supplies we can offer a whole range of specialist foams for industrial, marine, and commercial projects. Please contact us to discuss the needs for your specific project and we will work with you to find the right solution for you.


Spray foam insulation is a totally inert product and does not disintegrate or deteriorate over time. It doesn’t not need to be topped up regularly.

SEAI Grant

Spray Foam is suitable for the SEAI insulation grant. In order to qualify you must apply for the grant before starting any insulation works.

NSAI Certificate

The National Safety Authority of Ireland have exhaustively tested our foam to ensure that it is safe for use in Irish properties.
