What is the most cost effective insulation?
Closed-cell spray foam has the highest R-value of any insulation, up to R-6 per inch.
It takes up less space than fiberglass or blown-in insulation.
It can also save up to $500 a year in energy costs.
Expect to spend $300-to-$600 for a DIY foam insulation kit to cover 200-square-feet..

What is the R value of 1 inch Styrofoam?
3.6 to 4.2 per inch• Also called Styrofoam insulation, this is the least expensive material. It provides R-values that range from 3.6 to 4.2 per inch. Some products have reinforced facing to make them sturdier.
What is the best R value for insulation?

Performance. Sprayed-on cellulose and fiberglass work about as well as loose fill, but sprayed-on mineral wool performs better than loose fill, at R-4.1 per inch. Any spray-on insulation will seal air leaks better than loose fill.
What is the thinnest insulation with the highest R value?
Aerogel insulation offers the highest R-value of any insulating material at less weight and thickness—ideal for construction, refineries, pipelines, and thin-gap thermal barriers.
What can you use instead of insulation?
It’s mold-, moisture- and fire-resistant as well. Cellulose spray is made from recycled paper products, primarily newsprint, and is the most environmentally friendly insulation option out there, with a recycled material content of 85%….Non-Fiberglass Spray InsulationIcynene.Soy.Cellulose.Polystyrene.
Which is better spray foam or insulation?
R-value is a simple “the higher, the better” statistic. On paper, spray foam is the clear winner in this category, as closed cell foam can reach staggering R-value heights of up to 7.0. It also doesn’t sag or settle over time, a side effect that fiberglass insulation suffers from when it’s installed incorrectly.
What is a good U value for insulation?
The best insulating materials have a U-value of close to zero – the lower the better. Building regulations currently stipulate that for a new building, the elements must have maximum U-values as follows: Wall – 0.3 W/m2k. Roof – 0.15 W/m2k.
What is the best type of attic insulation?
Fiberglass, cotton, and mineral wool can all work as loose-fill material, but the far and away top choice for blown-in insulation is fiberglass. Contrary to batts, blown-in fiberglass insulation is perfect for filling in tight voids around wiring, pipes, or any area with awkward framing.
