Building Product Innovations That Changed Construction Workflows in the Late 1990s

The late 1990s marked a turning point in residential and light commercial construction, as manufacturers introduced products that addressed long-standing inefficiencies in framing, drywall finishing, anchoring, plumbing, and exterior cladding. A 1997 roundup by Leland Stone in the Journal of Light Construction cataloged several of these innovations, many of which laid the groundwork for techniques builders still use today. This article examines those products in detail, explaining the problems they solved and the principles behind their design. For a broader look at finishing materials and coatings, see our article on Glazing Clay Products Ceramics, which covers surface treatments and ceramic finishes used in construction.

Smarter Framing and Drywall Solutions

Two of the most labor-intensive areas of residential construction have always been corner framing and drywall finishing. Conventional methods required extra lumber, multiple passes of joint compound, and careful attention to avoid cracking. Products introduced in the late 1990s offered simpler, faster alternatives.

Eliminating Cold Corners with Warm Corner Framing Clips

Traditional corner framing requires a third stud used as backing for drywall. This approach creates several problems:

• Extra lumber cost for the blocking stud
• A cold corner where insulation cannot reach the interior surface
• Moisture accumulation in the uninsulated void
• Corner cracks caused by differential movement between framing and drywall

The R-Plus Warm Corner Framing Clips from Stud Claw/U.S.A. addressed all of these issues. These galvanized steel clips attach to corner studs or top plates at 16 inches on-center, creating a rigid backing for drywall panels without a third stud. The clips install by hand and require no fasteners. When the second corner panel is positioned, it wedges the first panel firmly against the clips, producing a floating corner that isolates the wall panels from frame movement. This design allows the structure to shift and settle without transmitting stress to the drywall surface.

A box of 500 clips, enough for an average 2,000-square-foot home, cost about $57 at the time. The reduction in lumber, labor, and future repair calls made the investment worthwhile. These clips represent an early example of what the industry now calls advanced framing, a method that optimizes material use while improving thermal performance.

UltraFlex Joint Tape – A Faster Approach to Drywall Finishing

Drywall taping is a skill that takes years to master, particularly on outside corners where steel bead has traditionally been the standard. Steel bead has several drawbacks:

• It requires precise cutting and nailing
• It does not adapt well to off-angle corners
• When struck, it sheds flakes of dried joint compound that are difficult to repair seamlessly

UltraFlex, manufactured by No Coat, offered an alternative. This prefinished laminated tape consists of two layers of paper bonded to one layer of plastic. When folded, it becomes more rigid than steel corner bead, yet it readily conforms to angles that are not exactly 90 degrees, making it ideal for archways and non-standard corners.

The key benefit was speed. Corner joints taped with UltraFlex were typically ready to finish on the same day they were applied. The manufacturer recommended using thinned all-purpose joint compound and applying it more generously than with standard tape. Using a 6-inch taping knife, the taper squeezes excess mud from under the tape and feathers the edges into the wall surface. A 100-foot roll cost about $45. One caution: the tape edges may telegraph through wet finishing materials if not covered adequately, so extra care during application is important.

Advanced Adhesives and Anchoring Systems

Anchoring hardware into concrete and masonry has always demanded adhesives that can withstand heavy loads, temperature extremes, and moisture. Traditional epoxy systems required precise mixing ratios and careful application. The introduction of vinyl urethane adhesive capsules in the late 1990s changed this workflow significantly.

Understanding Two-Part Vinyl Urethane Adhesives

Hilti’s HVU (High Viscosity Urethane) system packaged the two components in a single capsule. The installer inserts the capsule into the drilled hole, then drives the threaded rod or rebar into the capsule, shearing the inner seal and mixing the components as it advances. This approach eliminates measuring errors and ensures consistent material properties across every installation.

The HVU formulation includes a high aggregate content, which provides three practical benefits:

• The mixture does not run out of overhead or vertical holes
• The adhesive remains in place even in gaps larger than the rod diameter
• The product can be installed in freezing temperatures, extending the construction season in cold climates

Application Best Practices for Adhesive Anchors

For rebar dowels, a practical technique emerged: shear the end of the dowel at a 45-degree angle, chuck it in a roto-hammer, and drive it into the prepared hole. The angled tip helps break the capsule and distribute the adhesive evenly. For rebar larger than the drill chuck capacity, the manufacturer offered an adapter chuck.

The HVU capsules were available in diameters from 3/8 inch to 1-1/4 inches. A pack of five 5/8-inch capsules listed at $40.25. The product could be purchased directly from the manufacturer, bypassing distribution delays. Understanding the chemistry of cement-based materials helps explain why these mechanical anchors perform well in concrete. See What Are the Products of Cement Hydration for a detailed explanation of the chemical reactions that give concrete its strength.

Efficient Mechanical Systems for Modern Homes

Hot water delivery lag is one of the most common homeowner complaints. Waiting 30 to 60 seconds for hot water at a distant faucet wastes water and energy. Traditional solutions involved a point-of-use heater under the sink or a dedicated recirculation loop with a return line. Both added significant cost to new construction and were difficult to retrofit.

The Metlund D’Mand Hot Water Circulation System

Advanced Conservation Technology introduced a third option called the Metlund D’Mand System. Rather than requiring a separate return pipe, this system uses the existing cold water supply line as the return path. A pump mounted at the fixture shunts the cooled standing water back through the cold water line, displacing it into the water heater’s cold supply. The result is that hot water arrives at the tap within seconds, and the cooled water is not wasted down the drain.

The standard kit connects to a faucet or shower up to 75 feet from the water heater. It includes a manual start switch that can be configured in three ways:

1. Manual activation with a push button at the fixture
2. Automatic activation triggered by the flow of water when the faucet opens
3. Temperature sensor activation that starts the pump when the standing water temperature drops below a set threshold

Faucets located between the pump and the water heater can be equipped with an optional remote wireless switch. In all configurations, the pump shuts down automatically when the water temperature rising through it increases by 2 degrees Fahrenheit, signaling that the cool standing column has been replaced with hot water from the heater. Prices started at around $305.

Comparing Recirculation Methods

The demand-controlled approach represented a significant step forward in water conservation, particularly in larger homes where the water heater is far from the master bathroom or kitchen.

Precision Tools and Durable Exterior Materials

The final group of products from the 1997 JLC roundup includes a manual miter box designed for trim work and a composite lap siding that addressed the shortcomings of earlier engineered wood products. Both demonstrate how thoughtful engineering can solve practical job-site problems.

The J.D. Miter Box – Precision Without Power

For small jobs and crown molding installations, the J.D. Miter Box from Rydal Creek Company offered a manual alternative to power miter saws. Its design included several features suited for finish carpentry:

• Two fences that adjust independently for precise compound cuts
• Non-slip material covering both fences to prevent workpiece movement
• Clamps on both fences to hold crown molding securely in position
• An open frame design that allows cuts from the back as well as the front
• A guide system of magnetized steel posts that grip the saw blade during the entire cut

While crown molding still had to be cut upside down, the ability to approach from either side simplified positioning long workpieces in tight spaces. The magnetized guide posts were the most innovative element, providing hands-free blade guidance that improved accuracy over traditional saw guides.

Smart Lap Composite Siding – Learning from Past Failures

Engineered wood siding suffered high-profile failures in the 1980s and early 1990s due to moisture absorption, dimensional instability, and decay. Louisiana-Pacific’s Smart Lap siding represented a response to these problems. The product was a composite lap siding made from specially shaped wood chips chemically united with a polyurethane binder. This formulation produced a board that was more dimensionally stable than solid wood siding.

Key features included:

• Impregnation with powdered zinc borate for protection against fungal decay and insects
• Factory-primed surface with embossed wood-grain texture
• Triple-coated drip edges for moisture protection at the most vulnerable point
• Transferable warranty covering 100 percent of repair and replacement for five years
• Prorated coverage for an additional 20 years on product replacement

The boards were sold in bundles of five, available in 6-inch or 8-inch widths at 16 feet long. Cost started at approximately 70 cents per square foot, making it competitive with premium vinyl siding while offering the appearance and workability of wood. The use of zinc borate as a preservative was particularly notable, as this treatment had proven effective in other wood composite applications without the environmental concerns associated with older preservative chemistries.

Lessons from 1997 That Still Apply Today

The products highlighted in the JLC roundup share a common theme: each addressed a specific job-site problem with a targeted engineering solution. The warm corner clips eliminated thermal bridging and cracking. The adhesive capsules removed guesswork from anchor installation. The demand-controlled pump reduced water waste without expensive retrofits. The composite siding tackled moisture durability head-on. And the manual miter box proved that sometimes a well-designed hand tool outperforms a power tool for precision work.

For builders evaluating new products today, the same criteria apply. Does the product solve a real problem? Does it reduce labor or material costs? Does it improve durability? The products that survived into common use are those that answered yes to all three questions.
