Spray Foam Insulation in Allen, TX

Closed-cell is dense, roughly R-6 to R-7 per inch, adds rigidity, and works as a moisture and air barrier, which suits tight cavities, rim joists, and damp areas. Open-cell is lighter, about R-3.5 to R-3.9 per inch, expands more to fill gaps, dampens sound, and costs less, but it's vapor-permeable and not a moisture barrier.

It's a two-part chemical system that needs specialized rigs, trained applicators, and protective gear, and it air-seals as it insulates instead of just adding R-value. That higher upfront price often buys better air-sealing and more R-value per inch, which counts most in tight spaces where blown-in can't reach.

Yes, plan to be out. During spraying and through the manufacturer's re-occupancy window, commonly around 24 hours, the foam cures and off-gasses, so occupants and pets need to stay clear of the house. Ventilation is required during and after the application, and your installer confirms the exact re-entry time for the specific product being used.

The two foams behave differently. Closed-cell acts as an air barrier and, at sufficient thickness, as a vapor retarder as well; open-cell stops air movement but stays vapor-permeable. That distinction matters because a vapor-closed assembly that cannot dry will hold moisture inside the structure, so the type you choose has to suit your climate and your specific wall or roof assembly.

Four things, mainly: the foam itself, since closed-cell runs noticeably more than open-cell; the thickness and R-value you are targeting; the square footage; and any prep or removal of existing material. An open attic roofline is a very different job from filling wall cavities, which is why a proper quote spells out type, thickness, and area.

Everything visible — facing, mantel, hearth, built-ins. None of it is structural. The limits are the appliance's published clearances and the size of the opening.

Only by changing the appliance, which brings the flue with it. That turns a finish project into a construction one, and it is worth knowing before you fall in love with a drawing.

Published distances from the opening to anything combustible, including how deep a mantel may be at a given height. We design to the manual and show you the page.
