Why Multi-Family Insulation Is Different

Apartment buildings and multi-family properties have unique challenges: shared walls, between-floor assemblies, common areas, and occupied units that need minimal disruption during installation. We specialize in efficient, low-disruption projects for property owners and managers.

Where We Insulate

Multi-Family Insulation Zones

Every zone in a multi-family building has a different insulation strategy. We assess the full envelope and recommend the right material for each location.

Attic & Roof Deck

The attic or roof deck is typically the highest-impact upgrade. Blown-in insulation or closed-cell spray foam applied at the roof deck eliminates heat loss and ice dam risks.

Between-Floor Assemblies

Open-cell spray foam or blown-in insulation in the joist bays between floors reduces sound transmission between units, a top tenant comfort complaint.

Exterior Walls

Injection foam or blown-in cellulose added to exterior wall cavities without tearing out interior finishes, minimal disruption to occupied units.

Party Walls (Shared Walls)

Properly insulating walls between units improves fire ratings, soundproofing, and thermal performance, all critical in multi-family construction.

Rim Joists & Basement

Closed-cell spray foam at rim joists and basement walls seals the building envelope at the foundation, eliminating cold floors on lower units.

Mechanical Rooms

Insulating mechanical rooms and common areas reduces heat loss from shared systems and protects pipes from freeze damage in Minnesota winters.

The Process

What to Expect on a Multi-Family Project

Most multi-family calls we get in the Twin Cities come from property owners who have dealt with high utility bills or tenant comfort complaints without finding the fix. The thing with multi-unit buildings is that the problem usually comes from several places at once: the attic above the top floor, the rim joists along the foundation, sometimes the party walls or exterior walls. We assess the whole envelope, not just the obvious spots, so the work actually solves the problem.

We schedule around occupied units and coordinate with the property manager from the start. Most work happens from attic access points, mechanical rooms, or common areas without entering a rented unit. When Xcel Energy or CenterPoint rebate programs apply, we handle everything: the pre-install blower door test, the post-install test, and filing the rebate. The check goes directly to you.

Property Owner Benefits

Why Property Owners Choose Us

Reduce Tenant Turnover

Drafty units and high utility bills are leading reasons tenants don’t renew. Proper insulation directly improves tenant satisfaction and retention.

Lower Operating Costs

If utilities are owner-paid, insulation upgrades cut heating and cooling waste. ENERGY STAR estimates about 15% savings, a direct improvement to your NOI.

Sound Control Between Units

Between-floor and party-wall insulation reduces airborne noise between units, improving the living experience and your building’s appeal.

Code Compliance

Many Minnesota energy codes require minimum R-values for renovations and additions. We ensure your project meets all current IECC requirements.

Common Questions

Frequently Asked Questions

Yes, most of our multi-family work is done with tenants in place. We schedule unit-by-unit access with property managers and complete each unit in a single shift. Most tenants can re-enter the same day.

For owner-paid utilities, typical payback is 3–6 years. For tenant-paid utilities, ROI comes from reduced turnover and higher rents, properties with lower utility bills attract and retain tenants more easily.

Yes. We have the crew size and equipment to handle projects from duplexes to 100+ unit complexes. Contact us for a building walkthrough and custom quote.

Closed-cell spray foam for rim joists and roof decks, open-cell spray foam for between-floor assemblies, and blown-in cellulose or fiberglass for attics and wall cavities, chosen based on each location’s performance requirements.

Yes. Xcel Energy and CenterPoint Energy both have commercial and multi-family rebate programs. We handle all paperwork and help you maximize every available rebate.

Prices follow material costs, so a number published today could be wrong next month. Call and you will talk directly to Travis, the owner. He can usually share current ballpark and per-square-foot ranges over the phone, then give you a firm quote after seeing your building.
