The GBT Difference

Why Architects & Builders Choose GBT

Our profiles undergo rigorous quality testing at every stage — from raw material selection to final extrusion. GBT uPVC combines European manufacturing standards with Indian climatic expertise.

🌿

Lead-Free Formula

100% lead-free stabilizers — safe for families and the environment, compliant with international green building standards.

🔬

Co-Extrusion Tech

Color molecularly bonded into the profile — never painted on. UV-stable and fade-proof throughout 15+ years of service.

⚙️

±0.2mm Tolerance

Industry-leading wall thickness tolerance ensures perfect fit, smooth operation, and structural integrity across every profile.

Quality Assurance

Four Pillars of GBT Quality

Quality is at the heart of everything we do. Every GBT uPVC profile is rigorously tested to meet international standards for durability, dimensional precision, surface finish, and environmental safety.

Everything That Makes uPVC
the Right Choice

Our environment-friendly, lead-free GBT uPVC profiles deliver a comprehensive range of advantages — from aesthetics and durability to safety, security, energy savings and long-term sustainability.

🛡️

Durability

GBT uPVC profiles are not prone to warping, twisting, or splitting. Precision impact modifiers ensure a long, reliable service life.

🌿

Environment Friendly

Being a lead-free product, it is non-toxic and harmless to the environment. Saves forests by eliminating dependence on wood and aluminium.

🦟

Bug Mesh Option

Mosquitoes and other insects are a serious threat. GBT profiles support integrated bug mesh options for door and window systems.

🔇

Sound Insulation

In addition to thermal insulation, GBT profiles provide special acoustic insulation. Sound reduction can reach up to 40 decibels.

☀️

UV Resistance

GBT uPVC profiles are 100% UV resistant and contain the ideal quantity of TiO₂, which aids in preserving natural whiteness even after prolonged sun exposure.

🔥

Fire Retardant

GBT uPVC profiles are naturally flame retardant. uPVC will not cause, support, or encourage the development of fire, meeting safety requirements.

🏠

Indoor Air Quality (IAQ)

By minimizing internal energy loss, indoor air quality is maintained. Our profiles cut energy loss by more than 30%, reducing heating and cooling expenses.

🐛

Termite & Corrosion Resistance

GBT profiles have termite and corrosion protection built in. Salts, acids, alkalis, and waste gases do not rust or damage our systems.

💰

Excellent Cost Benefit

Compared to wood frames — generally 40% more expensive — GBT uPVC profiles save significant cost through maintenance-free operation and energy efficiency.

🌦️

Weather Resistance

Manufactured for tropical climatic conditions. Prolonged exposure to sun, rain, wind, and humidity never affects quality or dimensional stability.

🔧

Maintenance Free

GBT uPVC profiles for doors and windows are dirt-proof and easy to maintain. Cleaned simply with soap water — no painting or treatment needed.

♻️

Recyclable

GBT uPVC profile systems are designed with full recyclability in mind, making them a sustainable choice for green building projects across India.
