Why Los Gatos Residents Choose Us for Reflectix Service
Wes Okafor, our owner and lead technician, learned the trade at Olive-Harvey College on Chicago’s Far Southeast Side, where blower-door equipment came before cellulose bags. That sequence still governs how we work in Los Gatos: seal first, then insulate. We’ve found that Los Gatos’s hillside homes reward this discipline more than flat-valley properties because cold-air drainage off the Santa Cruz Mountains pulls heat out faster than standard construction assumptions allowed for.
We stock genuine Reflectix product lines locally - Double Reflective bubble-pack rolls, single- and double-sided foil rolls, rafter-facing barrier, and duct wrap - so Los Gatos jobs don’t wait on shipping. Our crew carries OEM-compatible fasteners, spacers, and baffles sized for the 3/4-inch minimum airspace Reflectix requires. Every job closes with a Documented Photo Record and, on applicable work, before-and-after blower-door readings.
Under Haven Standard Clause 1, you get a flat written price and written scope before anyone lifts a tool. No exceptions. Our 365-Day Done Right Promise applies to all completed work in Los Gatos.
Common Reflectix Insulation Problems We Solve in Los Gatos
- Foil installed directly against roof decking with no airspace. In Los Gatos hillside cathedral ceilings, this collapses radiant performance and traps moisture against sheathing during the wet season. The Santa Cruz Mountains deliver storms that don’t dry quickly on north-facing slopes, so an unspaced Reflectix layer becomes a vapor trap instead of a barrier.
- Bubble-pack crushed in kneewalls and rim areas. Los Gatos’s 1960s-1980s custom homes have complex attic geometries where installers walk across the product. Punctured bubble-pack leaves foil facing the wrong direction, turning it into a non-radiant dust collector that does nothing for your envelope.
- Aluminum foil oxidation after years in 140°F+ summer attics. Los Gatos’s south-facing hillside roofs bake harder than valley properties. Separated, flaking foil means R-value claims no longer hold and the homeowner is paying for a product that’s already failed.
- Reflectix stapled over attic vents, ridge vents, or baffles. Common in DIY jobs around the historic downtown district’s pre-1950 homes. Blocked ventilation paths cause condensation and, in some cases, rot at the deck - a repair that runs far past any insulation budget.
- Original rigid foam too thin for modern code, with Reflectix added as a band-aid. Many 1970s Los Gatos hills homes have 2-3 inches of rigid foam under the decking, well below R-38 CZ4 requirements. Slapping foil over insufficient foam doesn’t fix the thermal bridge; it just hides it until the next energy bill arrives.
Reflectix Service in Los Gatos: What Local Conditions Mean for Your Equipment
Los Gatos hillside homes built in the 1960s-1980s sit on steep, shaded, north-facing lots where roof decks rarely dry out between storms. This changes what Reflectix is doing in your assembly. Here, it’s a radiant and a moisture-management decision, not just a summertime heat-reflector. Any foil we install has to be airspaced and vented, or it makes the assembly worse than bare decking.
We’ve measured this. In a 1970s exposed-beam hillside home off Kennedy Road, our tech found Reflectix bubble-pack stapled tight against the roof deck with the foil facing down and zero airspace. The homeowner thought the attic was “already radiant-barriered,” but summer attic temps still hit 145°F and the furnace ran hard on cold downhill nights. We pulled the crushed foil, laid genuine Reflectix Double Reflective roll with a proper 3/4-inch airspace and baffling to keep the ridge path clear, then added closed-cell foam over the 2-3 inches of original rigid foam on the vaulted section. Attic temps dropped and the homeowner reported the upstairs bedrooms holding heat instead of dumping it into the night air. That’s the difference between installing foil and installing it right in Los Gatos’s microclimate.
Seal the leaks first. The insulation just holds what you’ve already captured.
Reflectix Models & Products We Service in Los Gatos
We install and repair the full Reflectix sales & service product line as part of real envelope jobs - never as a standalone gimmick.
- Reflectix Double Reflective Insulation Roll - bubble-pack in 5/16-inch and 1/4-inch thicknesses. We use this for attic floor and kneewall applications where the assembly allows proper airspace.
- Reflectix Reflective Foil Insulation Roll - single- and double-sided foil for rafter-facing and roof-deck installations in Los Gatos cathedral ceilings.
- Reflectix Attic Radiant Barrier / Rafter-Facing Foil Products - the correct layer for vented attic assemblies in hillside homes with proper baffle clearance.
- Reflectix Duct Insulation Wrap - for HVAC ductwork in Los Gatos’s older historic-core homes where conditioned air runs through unconditioned spaces.
We stock these products locally for fast Los Gatos turnaround. When Reflectix sizing or thickness can’t meet a specific assembly, we specify quality foil-faced alternatives and explain why in writing.

FAQs - Reflectix Insulation in Los Gatos
No. Reflectix is a radiant barrier, not insulation. In Los Gatos’s cold-air-drainage microclimate, bedrooms lose heat through conduction and air leakage, not just radiant transfer. We seal top plates, can-light boots, and attic hatch perimeters first, then add the correct insulation layer - dense-pack, spray foam, or blown-in - with Reflectix as a radiant component where the assembly allows. Call (669) 280-8103 for a free estimate that includes blower-door testing.
Minimum 3/4 inch, and we prefer 1 inch or more in Los Gatos’s wet-season conditions. Without this airspace, the foil can’t reflect radiant heat and may trap moisture against the deck. We install baffles to maintain this gap and keep the ridge vent path clear. Call (669) 280-8103 for a free estimate.
Only if the existing foam is dry, intact, and properly fastened. More often, that 2-3 inches of original rigid foam is below modern R-38 CZ4 requirements and may have absorbed moisture on north-facing slopes. We inspect with moisture meters and thermal imaging, then recommend either a Reflectix-plus-closed-cell hybrid or full foam replacement. Call (669) 280-8103 for a free estimate with documented photos.
Dense-pack cellulose or mineral wool for the wall cavities first. Balloon-frame walls in Los Gatos’s historic downtown core have zero cavity insulation and significant air leakage paths. Reflectix has no place in a wall cavity without airspace; it’s not a substitute for cavity fill. We dense-pack the walls, then evaluate whether a radiant barrier belongs elsewhere in the envelope. Call (669) 280-8103 for a free estimate.
We install genuine Reflectix Double Reflective roll for attic floors and kneewalls, and Reflectix Attic Radiant Barrier / Rafter-Facing Foil for vented cathedral assemblies. We do not install crushed, mis-faced, or unspaced product. Every installation includes proper fastening, airspace maintenance, and ventilation path protection.
