More R-value.
Less space.
A dense cell structure provides high resistance to heat flow in a compact layer. It is especially useful where framing depth is limited and every inch matters.

Comfort through changing seasons.
For Pomona buildings, good insulation means balancing thermal performance, air sealing, and moisture control. Closed-cell foam can support a durable envelope when the specification matches the construction and local conditions.
A whole-envelope review
Look at walls, rim joists, roof transitions, ventilation, and existing moisture conditions as one connected system.
Value Spray Foam Insulation brings a local-service mindset to projects with national reach. Tell us your Pomona project location, building type, and goals so availability and the right installation scope can be confirmed.
MORE THAN INSULATIONOne application.
One application.
A stronger building envelope.
Closed-cell foam expands into gaps and bonds to the surface, bringing insulation, air sealing, and moisture control together.
More R-value.
Keep outdoor air
where it belongs.
A continuous air seal reduces drafts and moisture carried by leaking air. At the specified thickness, many closed-cell products also act as a vapor retarder.
Built-in strength.
Lasting support.
The cured, rigid foam adheres to framing and sheathing and can improve an assembly’s racking resistance. Structural gains depend on the product and tested assembly.
R-values and vapor performance vary by product, thickness, and installation. Structural benefits supplement engineered framing; they do not replace it. SPFA product guidance ↗
WHERE COMFORT TAKES SHAPEFrom the crawl space
From the crawl space
to the roof deck.
We install closed-cell spray foam for residential and commercial projects. The right assembly starts with your building, climate, and goals.
Plan your installation ↗01 Crawl spaces & rim joists
Reduce drafts at the floor line and help keep crawl spaces warmer and drier. A complete moisture strategy may also need drainage, a ground vapor barrier, and humidity control. Repair active water intrusion before insulating.
02 Attics & roof decks
Slow heat flow through the roof assembly and reduce air leakage. Vented and unvented roof designs need different details, including condensation control, roof drying potential, and required ignition or thermal barriers.
03 Walls & new construction
Fill irregular cavities, seal around penetrations, and get strong thermal resistance in limited space. Continuous insulation may also be needed to reduce thermal bridging through the framing.
04 Metal buildings & commercial spaces
Create a bonded insulation layer on suitable substrates. Product compatibility, condensation control, fire protection, and the building’s use guide the specification.
Choose performance
that goes beyond R-value.
For tight spaces, moisture-sensitive areas, and projects that need a rigid air seal, closed-cell spray foam is often the strongest fit.
| What matters | Closed-cell spray foam | Open-cell spray foam | Fiberglass batts |
|---|---|---|---|
| Thermal resistance per inch | High; typically R-5.8–6.9 | Lower than closed-cell | Varies by density and fit |
| Air sealing | At tested thickness | At tested thickness | Separate air barrier needed |
| Water vapor control | Low permeability at specified thickness | More vapor permeable | Separate strategy needed |
| Physical structure | Dense, rigid, bonded | Softer, lower density | Flexible fiber blanket |
| Best considered for | Limited depth, moisture control, rigidity | Drying potential and sound absorption | Accessible cavities and lower upfront cost |
The best insulation depends on the assembly, climate, budget, and fire requirements. Closed-cell foam typically costs more upfront. Compare foam types ↗

GOOD QUESTIONS. CLEAR ANSWERS.Know what goes
Know what goes
into your walls.
Why choose closed-cell spray foam?
It combines high R-value per inch with air sealing, low vapor permeability at the specified thickness, and a rigid bond to the substrate. That makes it a strong choice when space, air leakage, and moisture control are priorities. Other insulation may suit different budgets, acoustic goals, or drying requirements.
Is spray foam a radiant heat barrier?
Closed-cell foam resists heat flow and seals air leaks. It is not a reflective radiant barrier. A radiant barrier uses a reflective surface next to an air space; your roof design determines whether one is useful.
Will it keep my crawl space dry and warm?
It helps reduce heat loss, air leakage, and moisture vapor movement through insulated surfaces. Standing water, ground moisture, drainage problems, and humidity still need their own solutions. A complete crawl-space design addresses all of these together.
Can it reinforce walls and roofs?
Some tested closed-cell foam assemblies gain racking resistance or other structural benefits from the cured foam’s adhesion and rigidity. The benefit depends on product and assembly testing. It does not replace framing, fasteners, bracing, or an engineer’s design.
How much thickness do I need?
Thickness depends on the selected product’s rated R-value, climate, local energy code, assembly, and condensation strategy. We plan the specification around the project rather than applying one thickness everywhere.
What should I expect during installation?
Assessment and preparation come first, followed by professional application and inspection. Occupants and pets stay out of the work area during application and return only after the manufacturer’s ventilation and reoccupancy requirements are met. Required fire-protective layers are part of the assembly design.
