June 2026

From a half-acre of unpaved ground on Jackson Street in 1946 to a multi-location operation serving builders across New England, our story has always been simple: work hard, buy right, keep your word, and treat people like family. The bright yellow trucks, the first drive-thru lumberyard, the partnerships forged at the counter and on the jobsite—each milestone reflects a promise to show up prepared and finish strong. This timeline highlights the moments that shaped Jackson Lumber & Millwork: the ideas we bet on, the people who built them, and the communities we’ve served along the way. Eight decades in, new tools and technologies have changed how we work— but not why we work. Here’s how a family blueprint became a business built to last.

Built to Last Jackson Lumber & Millwork Story. A Family Legacy: 1946 to Today.

1946 Jackson Street Vision

1950s: Growth & Grit Demand for housing surges. Jackson expands operations to Market & South Union Streets and installs its first rail spur to unload full cars of lumber. A new woodworking shop produces custom windows, doors, and cabinetry. Despite the textile industry’s decline, Jackson helps revive Lawrence by supporting redevelopment of the city’s vacant mills.

1960s Innovation & Expansion Jackson purchases the David Brown Bobbin & Shuttle buildings and moves millwork operations there. In 1964, the company builds New England’s first drive-thru lumberyard—an innovation that draws national attention. New product lines arrive: aluminum storm windows, paint, and lighting fixtures.

Joseph Torrisi, a contractor, founds Jackson Lumber on less than half an acre of unpaved land in Lawrence, Massachusetts. With his brothers and a handful of dedicated employees, he begins building supplies. The first yellow trucks roll out, soon becoming a regional icon.

1970s: Joining Forces Jackson joins LMC (Lumbermens Merchandising Corporation), gaining national buying power and access to leading manufacturers. New ventures launch, including United Tool & Industrial Supply and expanded millwork manufacturing with the company’s first outside sales team. By decade’s end, Jackson’s reputation for service and quality extends across New England.

1980s Challenges & Resilience

1990s Modernization & Renewal With the economy rebounding, Jackson upgrades facilities and expands its customer base. The company’s first computer systems are introduced, revolutionizing pricing and inventory processes. A new generation begins to step into leadership, preparing for the next era.

A recession hits the building industry. Jackson endures through discipline and loyalty, consolidating operations and rebuilding stronger. Under Al’s leadership as President, the company modernizes operations, invests in technology, and begins a profit-sharing 401(k) plan—a commitment that continues today.

2000s Entering New Markets Jackson acquires Harvey Lumber in Haverhill (2000). In 2002, a 22-acre site in Raymond, New Hampshire, becomes home to Jackson’s growing millwork manufacturing center, with multiple expansions following. In 2008, Jackson Kitchen Designs opens in North Andover—a warm, design-focused showroom for homeowners and builders.

2010s Strategic Expansion Further growth includes a new Amesbury location (2012) and the acquisition of E.G. Barker Lumber in Woburn (2017), extending service to Greater Boston. In 2014, Jackson is named National ProDealer of the Year by ProSales Magazine—the first in New England to receive the honor. Facilities across Lawrence are modernized with new warehouses, corporate offices, and showrooms.

2020s Family & Future Now led by the 3rd generation— Jackson continues to innovate and invest in people, technology, and operations. The 4th generation have joined the business—are learning the trade from the ground up and carrying forward the values. With five locations, 25 delivery vehicles, and more than 200 associates, we remain a trusted partner for builders across New England— strong and proudly family-run for four generations.

Residential Span Chart

ABOUT FLOOR STIFFNESS Floor performance is greatly influenced by joist stiffness. Experience has shown that a floor system designed to minimum code acceptance may not meet the expectation of owners. TrimJoist® Corporation strongly recommends that floor spans be limited to those indicated in the optimal performance chart. Also, using a higher live load deflection limit such as L/600 as shown in the high performance chart above will result in a stiffer floor. The numbers in these charts far exceed minimum code requirements and are based on both gluing and nailing the sub floor. In cases where the sub floor is nailed only, spans remain the same, but the stiffness must be reduced by 20%. For optimal performance use screws in lieu of nails. GENERAL NOTES 1. Spans are based on uniformly loaded joists and include allowances for repetitive use members. 2. All TrimJoist® floor joists have a TOP orientation and should not be installed upside-down. 3. Limit total reaction (per end) to that indicated in the Maximum Reaction Table. 4. Stiffness factors (L/xxx) assume a minimum 3/4 inch span-rated sub floor that has been both glued and nailed. 5. Do not apply center supports, cantilevers, concentrated or asymmetrical continuous loads without first consulting a TrimJoist® representative.

DESIGN NOTES The uniform load span charts shown indicate the maximum design spans (including a 1 3/4" minimum bearing evenly trimmed) for each family of the TrimJoist® floor system. Most residential designs require a minimum of 55 PSF loading. Floors used for heavy traffic and/or heavy floor coverings (e.g. tile) should be designed at 65 PSF minimum. All loads are broken down into LIVE, TOP-DEAD and BOTTOM-DEAD components. For example, the 55 PSF column is really 40 PSF live plus 10 PSF top-dead plus 5 PSF bottom dead for a total of 55 PSF total load. Dead loads are the weight of the construction materials and are always present for the whole life of the structure. Live loads, on the other hand, are transient and are never constant over the life of the structure. These charts are for uniformly loaded, simply supported joists. For special applications requiring concentrated loads, asymmetric continuous loads, cantilevers, or special bearing conditions, please consult a TrimJoist representative or authorized dealer.

TABLE IBU-MF2 IB400, IB700, IB800 and IB900x Maximum Floor Spans. U.S. ASD (Allowable Stress Design). 40 psf Live Load (1 ¾” end bearing and 3 ½” interior bearing without bearing stiffeners) 15 psf Dead Load. Allowable Stress Design (ASD) 100% Load Duration (L/480 live load, L/240 total load deflection criteria).

NOTES 1. Allowable spans are applicable to floor construction. The live load and total load deflection limits are indicated at the top of the span table. 2. Spans are based on partial composite action with glued and nailed subfloor meeting requirements for APA Span Rated STURD-I-FLOOR conforming to PRP-108, PS 1, PS 2, CSA 0325, or CSA 0437. Construction adhesive shall meet the requirements given in ASTM D3498 or APA Specification AFG-01. 3. Minimum bearing length shall be 1 ¾ inch for end bearing and 3 ½ inches for interior bearings. Allowable design spans in the tables are measured from centerline of supports. 4. Bearing stiffeners are NOT required when I-joists are used with the spans given in the tables, except as required by hanger manufacturers. 5. These span tables are based on uniform loads. For applications with other than uniformly distributed loads, or other applications beyond the scope of the indicated design criteria, an engineering analysis may be required based on the use of the design properties accepted in the APA PR-L330 and Intertek CCRR 0322 evaluation reports. For technical support, contact IB or your local IB distributor. 6. Continuous spans given in tables IBU-MF1 thru IBU-MF3 are the longest spans measured between centerline of bearings for a joist with three bearings. The ratio of the shorter span to the longer span must be greater than 40%. For two spans with a ratio between 40% and 80%, provide metal hangers or equivalent to withstand an uplift force at the end of the shorter span. Calculate uplift force at the end of the shorter span when the longer span (only) is loaded with live load. 7. Continuous lateral support must be provided for the top and bottom flange of the I-joist. Provide lateral support at bearings to prevent lateral displacement or rotation. For all other applications, consult IB.

Web Hole Guidelines

INTERNATIONAL BEAMS

IB MAX-CORE I-Joist top and bottom flanges must never be cut, notched, or otherwise modified. Holes in web should be cut with a sharp saw. For rectangular holes, avoid over-cutting the corners, as this can cause unnecessary stress concentrations. Slightly rounding the corners is recommended. Starting the rectangular hole by drilling a 1” diameter hole in each of the four corners and then making the cuts between the holes is another good method to minimize damage to the I-joist. DIAGRAM IBUC-TH1 — Typical Holes

RigidLam LVL Floor Joists • Span Tables

Roseburg supports the installation of ½” gypsum wall board to the bottom of light-weight framing systems as required by Section R501.3 of the 2012 International Residential Code (IRC) and thus providing an economical layer of fire protection. However, when a gypsum wall board ceiling is not a viable option, Roseburg RigidLam Laminated Veneer Lumber (LVL) with a minimum cross-section of 1-1/2” x 9-1/2” may be used in lieu of 2x10 dimension lumber to meet exception 4 of Section R501.3 of the 2012 IRC. The adhesive used in RigidLam LVL has been rigorously tested in accordance with the heat durability requirements of ASTM D7247 and D5456, which ensures that the adhesive will not negatively affect the performance of the LVL in a fire. The following tables are meant to assist in the appropriate selection of RigidLam LVL used as floor joists. Alternatively, appropriate software such as Simpson Strong Tie® Component Solutions™ may be used to size RigidLam LVL floor joists.

NOTES 1. Spans are maximum clear distances between supports and are based on uniform loads. 2. Multiple span lengths shown require adequate lateral bracing of bottom edge of LVL. 3. Multiple spans are based on the longest span. The shortest span shall not be less than 40% of the longest span. 4. Live Load deflection is limited to L/480 or L/360 as indicated in the tables above. Total Load deflection is limited to L/240. 5. Spans do not reflect any additional stiffness provided by floor sheathing. 6. Spans are based on a minimum end bearing length of 1-3/4” and a minimum intermediate bearing length of 3-1/2” and the bearing capacity of SPF wall plate (425 psi) 7. Spans in bold italics are limited by intermediate bearing length of 3-1/2”. Use appropriate software to determine allowable span with longer intermediate bearing length. Note: Larger holes, more holes, and/or holes that are located outside of the shaded area shown may be permissible as verified by appropriate software (e.g. Simpson Strong-Tie® Component Solutions™) or engineering analysis.

• For beam depths (d) of 4-3/8 and 7-1/4 inches, the maximum hole diameter is 1, 1-1/8 and 1-1/2 inches respectively. • For deeper beams, the maximum hole diameter is 2 inches. • Diagram applies for simple and multi-span applications with uniform loading. • No more than 3 holes per span are permitted. • Holes should not be cut in cantilevers.

Web Hole Specifications — Residential Installation Details: Never drill, cut or notch the flange, or over-cut the web. Holes in webs should be cut with a sharp saw. For rectangular holes, avoid over-cutting the corners, as this can cause unnecessary stress concentrations. Slightly rounding the corners is recommended. Start the rectangular hole by drilling a 1" - diameter hole in each of the four corners and then make the cuts between the holes to minimize damage to the I-Joist.
