Glass wool blanket with aluminium foil roll for roof and duct insulation

Glass Wool Blanket with Aluminum Foil Supplier in Delhi — Alfatherm Insulation

Introduction

When it comes to thermal and acoustic insulation for industrial, commercial and residential projects in Delhi, a top-performing choice is the Glass Wool Blanket with Aluminum Foil. Alfatherm Insulation is a recognised supplier and manufacturer in Delhi that stocks a wide range of glass wool and foil-faced insulation products tailored for roofs, ducts, HVAC systems and industrial equipment.

This blog explains what foil-faced glass wool blankets are, why they are such an effective insulation product, where they are best used, and how to choose the right thickness and specification — with a special focus on sourcing from a trusted Glass Wool Blanket with Aluminum Foil Supplier in Delhi.


What is a Glass Wool Blanket with Aluminum Foil?

A glass wool blanket is a roll or sheet of spun glass fibres bound together to trap air pockets that dramatically reduce heat transfer. When one face is laminated or bonded with aluminium foil (or foil-scrim-kraft facing), you get added benefits: improved radiant heat reflection, enhanced moisture resistance and a neat protective surface that simplifies installation in exposed applications.

Key benefits

  • Excellent thermal performance: Glass wool offers very low thermal conductivity, making it efficient for minimising heat loss or heat gain in buildings and equipment.
  • Radiant heat control: The aluminium foil facing reflects radiant heat, which is particularly useful in hot roof spaces and metal buildings.
  • Moisture and vapour resistance: Foil facings reduce the risk of condensation when installed correctly on ducts, tanks or underside of roofs.
  • Acoustic damping: The fibrous structure also helps reduce airborne noise — useful in plant rooms and industrial enclosures.
  • Fire performance: Glass mineral wools are non-combustible and provide fire-resilient insulation when compared to many organic foams.


Common applications

  • Roof insulation for metal and concrete roofs (to lower rooftop heat gain)
  • Duct and HVAC insulation to prevent energy loss and condensation
  • Industrial vessel and pipe lagging for process temperature control
  • Acoustic linings for plant rooms and partition walls
  • Vehicle and cold-room insulation where a foil facing helps vapour control.

Why choose a Delhi supplier like Alfatherm Insulation?

Choosing a local, specialist supplier offers speed, technical support and compliance with local building norms. Alfatherm Insulation operates from Delhi and provides cut-to-size glass wool blankets, foil facings and related insulation products, making it straightforward to source the exact specification you need for your project. Local stock and distribution reduce lead times and logistic complexity for fast-moving projects in the NCR and North India.


How to choose the right specification

  • Thickness & density: Thicker blankets give better R-value; density affects both thermal and acoustic performance. Typical thermal conductivity for glass wool ranges around 0.030–0.040 W/m·K depending on density and manufacturing. Choose density and thickness to meet your R-value targets.
  • Facing type: Aluminium foil facing is ideal where radiant heat reflection and vapour control are required. For concealed, non-exposed installations, unfaced or kraft-faced blankets may be suitable.
  • Edge treatment & factory lamination: For HVAC ducts, look for factory-bonded foil facings that ensure a durable seal and simple fixing.
  • Fire & environmental standards: Confirm non-combustibility ratings and any local certifications required for your project. Reputable suppliers should provide data sheets and test reports.


Installation tips

  • Ensure the foil facing is installed facing the source of radiant heat (e.g., foil down under roofs facing the roof deck or foil facing the duct surface).
  • Seal joints and overlapped edges with foil tape to maintain vapour control and prevent thermal bridging.
  • Use protective clothing and masks while handling glass wool blankets to avoid skin or respiratory irritation during installation.
  • For ductwork, use appropriate adhesives and mechanical fixings recommended by the manufacturer.


Cost and lifecycle

Glass wool blankets are cost-effective both in purchase price and lifecycle savings. Insulation pays back through reduced HVAC loads and energy bills; industry studies show insulation investment yields considerable energy savings over its lifetime. Choose a supplier who can provide life-cycle performance data and installation support.


Finding Glass wool suppliers in Delhi

Delhi has several established glass-wool and mineral wool manufacturers and distributors. Alfatherm Insulation is one of the local names providing a wide range of wool products, and there are other manufacturers in the region that serve construction and industrial buyers — making it easy to compare specifications and prices locally. For project procurement, always ask suppliers for datasheets, available thicknesses, roll sizes and lead times.
