PU foam is one of the smallest items on any site. That is exactly why nobody thinks about it.

But the wrong can does not stay small. Windows lose their seal. Gaps open around pipes. Frames loosen. And the fix costs far more than the foam ever did.

Most buyers still compare only one thing: the price on the can. The price on the can tells you nothing about what the foam will cost you on site.

Here is a simple test. Try it once.

• Buy 12 cans of any other brand
• Buy just 4 cans of MULTIFOAM

Use both on the same site. Then check:

• How much each can covers
• How hard and strong the foam is after it sets
• How well it holds, and how much is wasted
• How long it lasts
• And the big one: how many cans did it take to finish the job?

You will see that MULTIFOAM uses fewer cans, holds stronger and lasts longer. And it costs you nothing extra.

One more thing you should know

Not all PU foam is the same formulation. In Germany and Europe, foam is classified by fire behaviour under DIN 4102: B1 (flame-retardant), B2 (normally flammable, the minimum permitted in construction) and B3 (highly flammable, meant for marine and general-purpose use, not buildings). Other countries follow different standards, but the principle holds everywhere: the formulation matters.

A contractor is not expected to know all this. But the foam that goes into your windows, walls and pipe openings is usually his pick. And his pick is almost always the cheapest can. That is rarely the safest one.

So ask one question: which foam is going into my project?

A truly sustainable building cannot be evaluated only by its HVAC efficiency, solar panels or the performance of its glass façade.

The building envelope must be considered as a complete system.

Solar-control glass, shading, façade orientation and urban landscaping help manage external solar radiation and the surrounding microclimate. But another important detail is often overlooked: the sealing and insulation of joints around doors and windows.

Even a high-performance façade can lose part of its intended performance if uncontrolled air movement and thermal losses occur through poorly sealed frame-to-wall joints.

One small but important installation detail: the gap.

For PU foam insulation around door and window frames, we recommend maintaining an approximately 10 mm continuous gap around the frame, and not less, where the joint design permits.

In actual construction, contractors often try to install frames with very little or no working gap. This leaves insufficient space for proper insulation and sealing.

A properly maintained joint allows MULTIFOAM PRO 5145 to perform its intended function around the frame perimeter, helping provide insulation and sealing and supporting the continuity of the building envelope.

The principle is simple:

No proper gap → no proper foam application → compromised joint performance.

Of course, MULTIFOAM does not solve the external heat-reflection issue of glass façades. That requires appropriate façade engineering, solar-control glass, shading, vegetation and urban design.

But sustainability also means ensuring that the carefully designed building envelope performs as intended right down to every frame joint.

For architects, developers and ESG professionals, perhaps the question should not only be: “How energy-efficient is the building?” but also: “Have we designed and executed every part of the building envelope to achieve its intended performance?”

Good design + correct material + correct installation = better building performance.

MULTIFOAM: supporting better building-envelope performance, one frame joint at a time.

The construction industry is a dynamic and multifaceted ecosystem, where every player operates with distinct priorities and philosophies. From my experience, developers largely fall into three broad categories:

Quality-Conscious. These are the rare but visionary developers who believe quality is non-negotiable. They back their teams with strong leadership and encourage a culture of continuous learning, staying updated with the latest products, technologies, and techniques. Every input, whether visible or hidden, is evaluated for its impact on performance and longevity. They also keep a keen eye on peer practices to remain ahead of the curve.

Cost-Conscious. These players are focused primarily on keeping project costs in check. While cost control is essential, their approach often sidelines innovation and quality. Without specialized teams to evaluate emerging solutions, decisions are driven by price tags, not long-term value. Their strategy is volume-driven, not value-driven.

Client-Centric. This category prioritizes buyer appeal: lavish lobbies, imported marbles, designer tiles, and eye-catching façades. The evolution in flooring alone, from mosaic to Italian marble, illustrates how aesthetics drive choices. Yet, behind the glamor, critical technical elements are frequently compromised:

• Appropriate grades of cement and steel
• Epoxy-coated rebars to prevent corrosion
• Clean, quality-assured sand for plastering
• Sound waterproofing and insulation for long-term resilience

While such projects may attract buyers initially, poor performance in structural integrity, acoustics, leakage, and durability eventually leads to user dissatisfaction, and damages brand reputation.

The Bottom Line: All three types of developers continue to sell and succeed. But every brand must decide: what do you want to be known for?
