How to Install Aerolam XLPE Sheets Effectively? A Practical Guide by Alfatherm Insulation

Introduction

If you’ve invested in Aerolam XLPE sheets for insulation, you’ve already made a smart decision. These sheets are trusted across India for controlling heat, improving comfort, and reducing energy costs. But here’s something many people overlook—even the best insulation material won’t work properly if it’s not installed the right way.

At Alfatherm Insulation, we regularly interact with contractors, factory owners, and site supervisors who ask us one simple question:

“What is the correct way to install Aerolam XLPE sheets so they actually perform well?”

This blog answers that question in a clear, practical, and easy-to-follow manner. No complicated terms, no confusion—just real guidance that works on-site.


Understanding Aerolam XLPE Sheets in Simple Terms

Aerolam XLPE sheets are made from cross-linked polyethylene foam and laminated with aluminum foil. In simple words, this means they block heat transfer and reflect radiant heat at the same time.

What makes them popular is that they are:

  • Lightweight and flexible
  • Easy to handle at the site
  • Resistant to moisture and condensation
  • Suitable for Indian weather conditions

When installed properly, these sheets can make a noticeable difference in indoor temperature and energy usage.


Common Areas Where Aerolam XLPE Sheets Are Used

You’ll often see Aerolam XLPE sheets installed in:

  • Factory roofs and metal sheds
  • Warehouses and logistics centers
  • HVAC ducts and pipelines
  • Cold storage buildings
  • Residential rooftops and walls
  • Pre-engineered buildings (PEB structures)

Each location has its own challenges, but the installation basics remain mostly the same.


Before You Start: Tools and Materials You’ll Need

A smooth installation starts with preparation. Make sure you have:

  • Aerolam XLPE sheets (correct thickness)
  • Measuring tape
  • Marker or chalk
  • Sharp cutter or blade
  • Aluminum foil tape
  • Adhesive or mechanical fasteners
  • Safety gloves and eye protection

Having these ready avoids rushed work and installation errors.

Step-by-Step Guide: How to Install Aerolam XLPE Sheets Effectively

Step 1: Prepare the Surface Properly

This step may seem basic, but it’s extremely important.

  • Clean the surface thoroughly
  • Remove dust, oil, or moisture
  • Make sure there are no sharp edges

A clean surface ensures the sheet sticks well and stays in place for years.


Step 2: Measure Carefully and Cut Neatly

Never guess measurements.

  • Measure the area accurately
  • Mark cutting lines clearly
  • Use a sharp cutter for clean edges

Uneven cuts can lead to gaps, which reduce insulation efficiency.


Step 3: Place the Foil Side Correctly

If your Aerolam XLPE sheet has foil on one side, always face the foil towards the heat source.
This allows the sheet to reflect heat instead of absorbing it.

This single step alone can significantly improve insulation performance.


Step 4: Fixing the Sheets Securely

Depending on your application, you can use:

Adhesive fixing:
Best for smooth surfaces and duct insulation.

Mechanical fixing:
Ideal for roofing, metal sheds, and industrial structures.

Make sure the sheet is fixed firmly but not compressed, as compression reduces insulation value.


Step 5: Seal the Joints Like a Pro

This is where many installations fail.

  • Seal every joint with aluminum foil tape
  • Do not leave gaps or loose edges
  • Press the tape firmly for long-lasting grip

Good joint sealing ensures continuous insulation and prevents heat leakage.


Step 6: Final Inspection

Before calling the job complete:

  • Check for open joints
  • Ensure sheets are aligned properly
  • Confirm uniform coverage

A quick inspection now can save repair costs later.


Common Mistakes to Avoid During Installation

  • Skipping joint sealing
  • Wrong foil orientation
  • Installing on wet surfaces
  • Overlapping sheets unnecessarily
  • Compressing the insulation

Avoiding these mistakes ensures the insulation performs exactly as intended.
