At Hewson Brothers, we carry a full lineup of top-tier insulation solutions—like XPS, EPS, PolyISO, mineral wool, batts, foam sealant kits, blow‑in, and basement blankets, to suit virtually any Canadian construction project. Whether you’re working on a cozy custom home, a commercial build, or something in between, we’ve got your back (and your walls).
The Products We Stock (and Why They’re Great)
XPS is a rigid foam insulation board that offers a strong combination of moisture resistance, high compressive strength, and consistent thermal performance. It’s an excellent choice for below-grade applications like foundation walls and slabs, as well as for insulating exterior walls and roofs in both residential and commercial projects. Its closed-cell structure helps prevent water absorption, making it ideal for demanding environments.
EPS is a lightweight, versatile foam board that’s commonly used in walls, roofs, and floors. While it has a slightly lower R-value per inch than XPS, it is more cost-effective and offers excellent long-term thermal resistance. EPS is especially suitable for continuous insulation in above-grade wall assemblies and under concrete slabs. It also performs well in insulated concrete form (ICF) systems and structural insulated panels (SIPs).
PolyISO is one of the most thermally efficient rigid insulation products available, offering a high R-value per inch. It’s often used in flat and low-slope commercial roofing systems as well as in continuous insulation applications for exterior walls. It’s lightweight, easy to install, and ideal when space is limited but high insulation value is required. PolyISO also has excellent fire resistance properties, making it a solid choice for code-compliant assemblies.
Mineral wool insulation is known for its exceptional fire resistance, sound dampening, and moisture resistance. It’s a go-to solution for cavity wall insulation, rainscreen systems, and fire-rated assemblies in both residential and commercial construction. It maintains its shape and thermal performance over time, even under high heat or moisture conditions, and is easy to friction-fit into place without sagging.
Pre-cut batts are a traditional and highly popular insulation option for framing cavities in walls, ceilings, and floors. They are easy to install and available in a wide range of R-values to meet different code requirements. Batts are particularly effective in wood or steel-stud framing for both sound control and thermal efficiency. Options range from basic fiberglass to higher-density batts for advanced performance.
Spray foam sealant kits are designed for sealing gaps, cracks, and penetrations in the building envelope. These kits expand to fill tight spaces and provide excellent air sealing performance, which improves energy efficiency and reduces drafts. They’re commonly used around windows, doors, sill plates, rim joists, and mechanical penetrations. Fast-curing and easy to apply, foam sealants are essential for airtight construction.
Blow-in insulation is ideal for attics, wall cavities, and hard-to-reach areas. It conforms to any space, creating a continuous thermal barrier with minimal air gaps. Whether used in new construction or retrofit projects, blow-in insulation can help improve energy performance quickly and affordably. It’s often chosen for its ability to cover irregular shapes and fill voids that batt insulation might miss.
