What are the benefits of block foam insulation?
Block foam insulation is "high velocity" so it loses heat more quickly than fiber glass.
Many people forgo building out their attics because they don't know what to do or how to do it - there are so many decisions between nailing down joists, installing vapor barrier, insulation thickness, roofing materials. Attic spaces also stay hotter during the summer and colder during winter months because heating and cooling fixtures blow hot or cold air directly into them instead of pushing that conditioned air through other parts of the home first (pro tip: seal up all old light fixture openings with caulking). But an insulated attic can be the perfect place to put all those extra storage containers without worrying about airflow-caused humidity build-up .
In short, block foam insulation is a quick and easy solution for an attic that's not being used at all, but it's even more effective when paired with other insulation types to create a well-rounded thermal barrier. This DIY guide will show you how to block the heat out of your attic, step by step.
First, look around and map out where power outlets and light fixtures are located throughout the space so you know where to install block foam insulation and where it needs to be left bare (e.g., no block foam insulation needed under/around these). The main thing is to avoid creating any potential fire hazards by leaving spaces uncovered or covered in flammable material such as fiberglass batting or rolled-out newspaper ( have I mentioned block foam insulation is flammable?).
Once you've mapped out the bare spots, go around the room inspecting for spots without block foam insulation or where block foam insulation has fallen down or shifted. Install new block foam insulation over top of the old block foam insulation using adhesive caulk . While you're at it, make sure to fill in any holes that have created along the existing block foam installation. Pay special attention at corners and vents - these are common trouble areas that can cause increased air movement into/out-of the attic if not blocked off.

How does block foam insulation work?
Block foam insulation provides effective air sealing, neat installation for clean surfaces, and easy access to the enclosed space.
Block foam insulation is mainly made of closed-cell polyurethane materials which are hydrophobic or water resistant. They are designed to provide excellent thermal insulation, sound diminution with high levels of STC (sound transmission classification) ratings, better light reflection with high levels of R value ratings which gets absorbed by the material's mass.
The closed-cell polyurethane material prevents moisture from permeating through while also continuously drawing in outside air for ventilation and freshness. As a result it makes block foam insulation able to emit negative ions and release additional electrons which further nourishes our living environment. The block foam insulation is known as the perfect insulation material for block building. It has high resistance to moisture, rot and insects, which are common concerns in wet locations. The block foam insulation also reduces the chance of mold or mildew growth. By installing block foam insulation you can reduce high utility bills by insulating your home more thoroughly which helps prevent cold spells coming inside while keeping summer temperatures cool. Homeowners who have block foam insulation installed on their homes could save up to 50 percent off their annual heating and cooling costs while increasing the comfort level of living areas in their homes since it makes them cooler in the summer and warmer during winter time.
