The optimal thickness of intumescent coating depends on the material being protected, the required fire-resistance rating, and the product’s tested performance characteristics. Standard application thicknesses range from 0.5 mm to over 5 mm (20 to 200 mils), with structural steel often requiring between 1.5 mm and 3.5 mm for 60- to 120-minute ratings. For non-structural […]
Open-cell spray foam is preferred over closed-cell for many interior insulation projects because it offers superior sound absorption, cost efficiency, and structural flexibility in wall cavities and ceilings. It expands more during application, filling gaps and irregular framing more effectively without adding unnecessary weight or rigidity. Closed-cell foam, while denser and more moisture-resistant, often exceeds […]
Spray foam insulation is highly effective in Lowell due to specific regional climate factors that directly impact home energy efficiency and structural integrity. The area’s mix of humid summers, frigid winters, and high moisture levels creates persistent challenges for both temperature control and vapor management. Open-cell and closed-cell spray foam address these challenges by providing […]
Spray foam insulation significantly reduces energy bills for Hartford County homeowners by sealing air leaks, minimizing heat transfer, and improving HVAC efficiency. Compared to traditional insulation materials, spray foam forms an airtight barrier, limiting temperature fluctuations and reducing energy loss through gaps in attics, walls, and basements. Open-cell and closed-cell spray foam options each provide […]
Spray foam insulation, when applied correctly, delivers high energy efficiency. Improper handling, however, presents risks to both applicators and building occupants. In Petersham, MA, proper safety measures must be followed to account for the region’s seasonal climate swings, variable humidity, and strict environmental codes. Failure to follow protocol can lead to indoor air quality issues, […]
Spray foam insulation, when applied too thin, can lead to persistent moisture problems, energy inefficiencies, and structural vulnerabilities. In the climate of Hardwick, MA, where temperature swings and humidity levels can strain building envelopes, thin applications of spray foam often fail to deliver the air-sealing and R-value performance needed for consistent protection. Improper installation thickness […]
Spray foam insulation offers strong thermal resistance and air sealing when correctly installed. Mistakes during installation can compromise its performance, cause safety hazards, and result in costly repairs. The most common issues stem from surface prep failures, improper product handling, and incorrect application thickness. This article outlines common errors to avoid, based on field experience […]
Spray foam insulation performance depends on a combination of environmental, installation, and material-based variables. Core factors include substrate condition, ambient temperature and humidity, foam type, application technique, and curing conditions. Mistakes in any of these can lead to poor R-value performance, shrinkage, off-gassing, or delamination. Material properties and installer experience directly influence long-term thermal performance, […]
At Lamothe Insulation & Contracting, we work with homeowners and builders who don’t just want insulation they want healthier homes. One of the most overlooked ways to improve indoor air quality is by choosing the right type of insulation. That’s why mineral wool deserves a closer look. We’ve spent years installing and maintaining insulation systems […]
At Lamothe Insulation & Contracting, we hear this question often and for good reason. If you already have insulation in your attic or walls, but your home still feels drafty, or your energy bills keep climbing, it’s natural to wonder if adding more insulation will help. The idea of blowing new insulation over old material […]
