This is your comprehensive buying guide.

What is Spray Foam Roofing?

SPF foam roofing is a sprayed-on roofing material that features three layers of material. Specifics of how it is applied are in the next section.

Base SPF: The primary layer is 2-part spray foam polyurethane (SPF). The material has been used since the 1960s in various applications, so it is a known commodity with clearly defined pros and cons.

The spray foam is a mix of two substances, a polyol resin and an isocyanate. They are combined onsite in a mixing spray gun and applied.

This is closed-cell foam, which makes it waterproof and gives it a higher R-value of 6.6 per inch vs. about R-3.5 per inch for open-cell foam.

The result is a seamless and waterproof roofing material.

Notes:

  • Cost: The Cost column reflects windows of average size and most common features chosen by homeowners. Specific window costs will range slightly lower or higher based on the feature package chosen such as window size, glazing/glass package, extras like exterior cladding, custom grilles, built-in blinds or shades.
  • Types Code: S=single-hung; D=double-hung; C=casement; A=awning; G=gliding or sliding. Most window series also offer picture/fixed windows and bay/bow window assemblies.

Did you know? New construction windows are different from replacement windows.

All Pella series and all Andersen series except for Renewal series can be used for new construction or as replacement windows. — If they are new construction windows, the frames are manufactured with a nailing fin used to secure the windows to the home’s exterior sheathing.

Replacement windows are secured to the window opening through the side jamb, so the exterior siding doesn’t need to be disrupted.

If you’re doing a complete exterior makeover including siding replacement, then either type can be used.

Installation Costs

Window installation costs below apply to both professional (warrantied) labor and any supplies required for all window types, double-hung, casement, fixed, etc.

  • New window (non-replacement) installation cost: $250-$300 per window
  • Basic Vinyl or Fiberglass Replacement window installation cost: $250-$400 per window
  • Wood-frame Replacement window installation cost: $350-$850 per window (more labor to replace wood windows)
  • Bay/Bow window installation cost: $400-$750 per window assembly

Window installations do cost less for new construction projects for two reasons:

  1. There are no old windows to remove first and windows quickly nail to the exterior sheathing on the home.
  2. Installing replacement windows in older homes can take significantly longer if the window openings have shifted or warped or if they need repair. — These delays will increase installation cost.

Cost-to-Value Return at Resale

National home remodeling and sales data show that window replacement return on investment (value recouped at resale) ranges from about 73% for upscale windows such as Pella Lifestyle (previously Designer 750) series and higher, Andersen 400 Series and higher, plus Renewal by Andersen, and up to 80% cost-to-value return for more affordable Pella and Andersen window lines.

For example, if you spend $10,000 on new windows, the potential sale price of your home in the first 10 years will be $7,300 to $8,000 higher.

The cost-to-value return speaks to the value recouped at the time of selling your home. It does not take into account the commutative value of energy savings and/or other benefits such as the enjoyment homeowners derived from the windows upgrade.

New windows can help a home sell faster, especially when the listing price is near the upper end of a potential buyer’s target price range. The buyer will have the assurance that replacing windows won’t be an expense they will need to worry about for the next 15-25 years.

Pro Tip: If you plan to sell your home in the next few years, replacing the windows isn’t a cost-effective choice unless they are in such poor condition, they’ll turn off buyers.

A better approach is to give potential buyers an allowance sufficient to cover the mid-grade new windows like Pella 350 high-end vinyl/Impervia Fiberglass or Andersen 200/400 Series. — This would cover their costs. The buyers could also use the money toward a premium window series, allowing the buyers to choose the kind of windows they like the best for the price.

Andersen Vs. Pella Window Comparison

Pella makes a broader overall range of window series in different materials compared to Andersen. You can view and buy Andersen windows at Home Depot, while Pella windows can be viewed and purchased at Lowe’s.

Andersen makes four solid wood series and one affordable Fibrex composite series. Pella makes three solid wood series, and one fiberglass Impervia Series windows that compare with the Andersen’s most affordable 100 Series windows made of Fibrex, though at a much higher cost for Pella Impervia. This comparison would be based on the window frame materials only (fiberglass vs. Fibrex) and not a fair series-to-series (Impervia is a mid-tier fiberglass window series line from Pella) comparison.

Andersen 100-Series Windows

Did you know? The primary difference between Pella and Andersen is that Pella also makes three vinyl window lines, and one fiberglass-frame window. Pella Impervia, the fiberglass window series sits right in between the wood and vinyl product lines based on Pella’s pricing tiers.

Andersen, on the other hand, offers windows made from their proprietary composite material called Fibrex, which is made from 40% reclaimed wood fibers by weight (from the production of Andersen wood windows) combined with 60% thermoplastic polymer (PVC vinyl) by weight.

Note: Andersen also has a completely separate line of high-end Fibrex windows called Renewals by Andersen, which is a whole separate business unit/division within Andersen. RBA windows are made for replacement only and are sold through the in-home sales presentations by independent RBA dealers. We cover the Renewals by Andersen offering, right below the main lineup of Andersen windows.

Residential Solar Power Is Breaking Records – Solar Prices Increase

The Solar Energy Industries Association (SEIA) publishes the US Solar Market Insight report each quarter, in collaboration with the consulting firm Wood Mackenzie. Their 2021 Q4 report was published on December 14, and the outlook is promising despite recent supply chain issues around the world.

source: Alternative Power Solutions Inc.

  • The US exceeded 100 gigawatts of solar power capacity early in 2021, and more than 15 gigawatts were added between January and September 2021.
  • A total of 5.4 GW were added in the third quarter, and data for October – December 2021 will be available in the next SEIA report, which is expected for March 2022.

Solar power accounts for 54% of the new generation capacity installed in the US during 2021, making it the electricity source with the fastest growth. Wind power follows in second place, representing 35% of new capacity. This means solar and wind power account for 89% of total capacity additions in 2021, while natural gas represents 10% and all other sources only account for around 1% (this includes coal).

  • Fossil fuels still dominate the grid, providing 60% of the electricity used in the US according to the Energy Information Administration. Natural gas represents 40%, coal represents 19%, while petroleum is used to generate the remaining 1%.
  • However, this could soon change with the current growth rate of wind and solar power. Renewables are providing 20% of the electricity consumed, and more than half comes from solar panels and wind turbines.

For the first time on record, the US installed more than one gigawatt (1,000,000 kilowatts) of residential solar power in a single quarter. More than 130,000 home solar systems were set up in Q3 2021, at an average price of $3.06 per watt. If this pace can be sustained, the US will soon be installing over 500,000 home solar systems per year!
