Hi Robert. Thank you for the great review! We are happy we were able to help you out and meet your expectations. If you require anything else, let us know. The Cosy Crew. C Surfin2024-06-13Trustindex verifies that the original source of the review is Google. Just had Cosy top off my attic to R60 with Weathershield insulation. The guys were on time and did a fantastic job. Before starting the job they went through the process with me and then proceeded with laying out plastic to protect my floors and walls. Once they stretched out the hose to pump the insulation through and sprayed the WeatherShield in the attic. After removing the blower hose, plastic and tools, the vacuumed their work area. in addition to energy savings we will receive, we have noticed a quieter upstairs from the sound damping effect from the extra insulation. Highly recommend this company. Thank you, Clarence S

Attic Insulation FAQs
Wondering if attic insulation really pays off? We’ve put together answers to the most frequent questions about comfort, efficiency, and upgrades.
Still need clarity on attic insulation in Penhold?
Because of Penhold’s severe winter conditions, attic insulation is essential to retain heat, save money on utilities, and prevent issues like ice buildup on your roof.
Adding or upgrading attic insulation can reduce heating costs in Penhold homes by 15%–25%, most noticeably in houses with older or inadequate insulation.
Blown-in cellulose and fiberglass both perform well in Penhold’s cold weather. They strengthen existing insulation and add reliable protection against heat loss and rising energy costs.
Rooms that never feel warm enough, insulation that looks thin, or gaps in coverage usually mean it’s time to add more. Houses built before 1990 are the most likely to need upgrades.
Generally 20–30 years, but Penhold’s cold climate can reduce that. Inspecting your attic regularly helps avoid costly issues down the road.
By stabilizing indoor temperatures year-round, attic insulation reduces energy waste, protects your roof from harsh winter conditions, and helps avoid expensive repairs.
By reducing energy loss, attic insulation often pays back its investment in 3–5 years. Older homes in Penhold usually see the biggest gains.
Blown-in cellulose or fiberglass offers broad coverage for attics, while spray foam forms a solid barrier against drafts and dampness. Either option saves energy — your choice depends on your attic needs.
While more expensive at installation, spray foam excels at blocking heat loss, sealing gaps, and resisting moisture — ensuring reliable, long-term performance.
It’s ideal when you want to enhance existing insulation. Cellulose or fiberglass loose-fill covers gaps and uneven surfaces, raising efficiency without extensive work.
Spray foam excels in difficult spaces where batt or blown-in insulation won’t perform well. It’s especially useful for controlling air leaks and moisture. Have a professional assess your attic to confirm suitability.
For most Penhold homes, the attic floor is essential. But adding roof deck insulation further reduces heat loss and keeps the attic comfortable if it’s a usable space.
