Q

What is the R-value for the single component caulking foam?

A

The R-value for the single component foam is approximately 3.5 R per inch.

Q

What is the temperature limit?

A

For proper application, the foam should be applied between 55 – 90 F.  Below 55F, the foam resin will become viscous and the rate of extrusion from the cylinders will be slow.  For temperatures above 90F, the viscosity of the foam resin will decrease drastically.  Extrusion rates from the cylinders will become too fast to be controlled comfortably.

Q

How do you solve the extreme temperature application problems?

A

We do have ‘Summer’ and ‘Winter’ formulations for the market.  You may specify which formulation that you prefer when you order.

Q

How much does the foam expand after application?

A

The final expansion of the foam is directly proportional to the ambient temperatures.  The higher the temperature, the higher will the final expansion be.  In an ideal condition of 77F, 60% R.H., the average expansion of the cured foam is approximately 35%.

Q

Can I stop and reuse later?  How long?

A

Yes, you may stop and reuse the partially emptied cylinder later.  Shut off the flow of foam from the cylinder by turning the yellow color cylinder valve stem clockwise.  Do not empty the foam resin from the hose.  Insert a wire or nail about ½” into the tip of  the brass nozzle.  Store the cylinder indoor, away from direct sunlight, in a reasonable ambient condition.  The foam resin in the hose must be purged and replaced with new foam resin weekly if you wish to store the foam cylinder for a prolonged period of time.

Q

How do I control the size of the foam bead during application?

A

For applications that require finesse, we recommend upgrading your application kit to our metering dispensing wand.  You can control the size of the foam beads with this dispensing wand.

Q

My dispensing kit was clogged, but the foam resin in the cylinder is apparently fluid upon agitation and should be useable.  What should I do?

A

You may order a new dispensing kit.  This will include an 8 foot hose, ball-valve and brass dispensing nozzle.  Remove the old hose from the cylinder.  Clean the cylinder valve with solvent.  Connect the new kit, and you are ready to go.

Q

What is the R-value?

A

The R-value for the spray foam is approximately R8 per inch.

Q

Can I spray inside the existing wall and attics?

A

Yes, you may spray into existing walls and attics.  This is a common practice for residences in states with extreme cold or hot ambient conditions.  The densely packed closed cells of this product are ideal for insulating against these extreme ambient conditions.

Q

What can I do if foam sagged before cured during vertical application?

A

You may have applied too much chemical on a vertical surface on one pass.  Spray a thin coat on the surface.  After the foam achieves full rise, apply a new coat.  Building up the thickness of the foam this way will eliminate the sagging problem.
