34mm Durable Polyamide Insulation Strips for Frames

Technical Specifications

Overview

Polyamide insulating profiles reinforce aluminium doors and windows with strong structural stability, resisting deformation under heavy loads and harsh weather conditions. Their low thermal conductivity interrupts heat transfer, keeping interiors warmer in winter and cooler in summer. This dual seasonal benefit reduces the need for heating and air conditioning, lowering overall energy costs.

Compared with ordinary aluminium frames, polyamide profiles deliver superior insulation, greater durability, and improved indoor comfort. As an essential component of energy-efficient building systems, they help projects meet strict energy standards while offering long-term performance and sustainability.

Product Features

• Low thermal path through the frame – Polyamide strips interrupt heat flow between inner and outer aluminium sections, reducing thermal bridging and supporting compliance with modern energy codes.

• High shear resistance at the interface – Delivers long-term structural integrity by maintaining strong adhesion after knurling and crimping, even under continuous mechanical load.

• Tight tolerance for air and water tightness – Precision extrusion ensures consistent fit, improving sealing performance and minimizing leakage risks in demanding climates.

• Thermal expansion similar to aluminium – Matches aluminium’s expansion behavior, preventing stress at frame corners and ensuring long-term dimensional stability.

• Maintains properties in hot and cold climates – Retains insulation performance across seasonal temperature extremes, avoiding brittleness in winter or deformation in summer.

• Supports hardware mounting zones – Provides reliable structural support for locks, hinges, and accessories without compromising the thermal break function.

Product Advantages

• Versatile width for most residential and mid-rise systems – Fits common aluminium frame designs, making it suitable for new builds as well as retrofit projects.

• Fast insertion and reliable crimping reduce rework – Streamlines assembly on production lines, lowering installation errors and improving manufacturing efficiency.

• Helps stabilize sash/frame geometry under wind load – Reinforces frame strength, ensuring that windows and doors perform reliably in high-pressure environments.

• Improves acoustic comfort when paired with proper glazing – Reduces sound transmission through frames, supporting quieter and more comfortable indoor spaces.

• Lead time 7–15 days for responsive supply – Ensures quick delivery to match project schedules, minimizing delays for contractors and system fabricators.

Product Applications

• Residential windows/doors targeting energy code upgrades – Enhances insulation and comfort, helping homeowners meet new energy standards without major design changes.

• Light commercial storefronts and ribbon windows – Provides durable thermal separation for projects where large glass areas must balance aesthetics and efficiency.

• School and office retrofits seeking quick thermal wins – Allows energy performance improvements in existing buildings with minimal disruption to operations.

• Mixed-use projects where comfort and cost both matter – Balances performance and affordability, supporting developers who need durable, efficient solutions across varied spaces.

• Balanced designs that avoid deep frame redesigns – Offers reliable thermal insulation without requiring significant alterations to existing aluminium frame profiles.
