KBE 88: an energy-efficient profile

KBE 88 — an energy-efficient profile for PVC windows

KBE 88 is a modern profile solution designed for people who prioritize thermal performance, durability and clean aesthetics. Used in energy-efficient windows, this profile helps reduce heat loss and improve indoor comfort throughout the year.

Key benefits

• Multi-chamber design and increased profile depth improve thermal and acoustic insulation.
• Compatibility with advanced glazing units (triple or low-emissivity combinations).
• Durable gaskets and optimized installation depth reduce thermal bridges.
• Wide choice of colors, laminations and configurations to match interior design.

Technical features and performance

KBE 88 is engineered to minimize heat transfer: its generous installation depth allows for thicker, more efficient glazing units, enhancing overall window Uw performance when combined with proper installation.

• Construction: multi-chamber PVC profile with option for steel or composite reinforcement.
• Glazing options: double, triple, energy-saving glass, gas fills and coated layers.
• Sealing: two- or three-seal systems with long-lasting elastomer gaskets.

Correct selection of glazing and high-quality installation are essential for the KBE 88 profile to deliver its energy-saving potential in real-world conditions.

Thermal and acoustic comfort

A deeper profile and modern sealing solutions reduce heat loss and contribute to maintaining a comfortable indoor temperature with lower heating costs. When paired with acoustic glass units, KBE 88 also significantly reduces external noise.

Design flexibility

KBE 88 adapts well to various architectural styles: from classic wood-look laminates to matte modern colors, as well as narrow or wide sashes and decorative mullions. This makes it easy to match the frame to the building’s aesthetics.

Installation and maintenance

• Professional installation is recommended, ensuring correct mounting depth and proper vapor- and water-proof finishing of reveals.
• Inspect gaskets and fittings 1–2 times a year.
• Clean frames with mild detergents; avoid abrasives and strong solvents.

How to choose KBE 88 for your project

1. Assess the required thermal performance and local noise levels.
2. Choose the appropriate glazing (double/triple, gas-filled, low-E coatings).
3. Select lamination and hardware options to suit the interior.
4. Arrange professional installation and check warranty terms.

Frequently Asked Questions (FAQ)

How effective is KBE 88 against cold?
