ISOLINE LOW LINE For Premium Aesthetics
Achieve High-End Traditional Roof Aesthetics with Modern, Hidden Waterproofing Performance.
Flawless Architectural Vision. Invisible Engineering.
The Aesthetic Compromise
Architects and high-end home designers often face a frustrating roadblock. You design a stunning, premium property featuring traditional handmade clay tiles, natural slates, or complex low-slanted roof lines - only to find that building regulations or waterproofing limitations force you to compromise.
Standard waterproofing methods often require visible flashings, bulky ventilation accessories, or high roof pitches that alter the clean, elegant lines of your architectural design.
Meet ISOLINE LOW LINE
ISOLINE LOW LINE is the secret weapon for premium architectural design. Because it handles the primary waterproofing beneath the aesthetic layer, it frees you from the design constraints of traditional roofing.
It allows you to specify the exact high-end external materials you want - whether they are reclaimed tiles, bespoke slate, or low-pitch clay pantiles - knowing the engineering beneath is completely hidden, incredibly secure, and perfectly integrated.
Design Without Limits: Keep your rooflines sleek, your pitches low, and your external aesthetics completely uncompromised. Beautiful design meets invisible protection.
Why Premium Designs Spec ISOLINE LOW LINE
- Complete Design Freedom: Use premium, ultra-traditional, or handmade tiles that might otherwise fail modern permeability or pitch requirements on their own.
- Hidden Ventilation: The corrugated design provides natural, high-volume airflow under the tiles invisibly, eliminating the need for unsightly plastic tile vents that disrupt clean roof profiles.
- No Visible Plastic or Flashing: Keeps the external focus entirely on premium natural materials like slate, stone, and clay.
Waterproofing for Modern Cladding Tiles
The rise of contemporary brick-cladding tiles, such as the handmade Petersen Cover™ system, offers architects a striking, continuous envelope aesthetic. However, these decorative tiles inherently lack structural weather protection, leaving modern, low-pitch, or vertical boundaries highly vulnerable to wind-driven rain.
By placing ISOLINE LOW LINE directly underneath, you convert these decorative cladding elements into a high-performance system. The sub-roof acts as the continuous primary waterproofing plane, safely catching and draining any water ingress while giving you complete aesthetic freedom to spec premium exterior finishes.
Case Study: Mapledown House
At Mapledown House, a striking 2,475 sq. ft. contemporary domestic residence, Brendan Kilpatrick Architects sought to utilize premium Petersen Cover™ clay cladding tiles to create a bold, modern facade.
To overcome the tiles' lack of structural waterproofing, Project Architect Ali Rashid integrated ISOLINE LOW LINE as the core underlayment. The system integrated seamlessly with the handmade tiles, ensuring absolute weather protection and building security while delivering on the ambitious, border-pushing aesthetic.
