Properly insulating your attic roof is essential for maintaining energy efficiency, reducing heating costs, and creating a comfortable living space. Using natural, sustainable materials like Sisalwool Natural Fibre insulation not only provides excellent thermal performance but also ensures an eco-friendly approach to home improvement. In this guide, we’ll explore the process of insulating attic roof rafters step by step.
Why Insulate Your Attic Roof?
Insulating attic roof rafters helps to:
Insulating attic roof rafters helps to:
- Reduce energy bills by minimizing heat loss.
- Maintain a stable indoor temperature throughout the year.
- Prevent condensation and mold growth.
- Enhance the lifespan of your roof structure.
By focusing on rafter insulation, you address heat transfer directly at the roof, which is crucial if you use your attic as a living space or storage area.
What is Sisalwool Natural Fibre Insulation?
Sisalwool is a natural insulation material made from renewable fibres. It’s breathable, moisture-regulating, and highly effective in providing thermal and acoustic insulation. Unlike synthetic materials, Sisalwool offers a sustainable and healthy alternative for insulating attic roof rafters.

How to Insulate a Pitched Roof from Inside: Step-by-Step
Step 1: Assess Your Attic and Roof Structure
Before you begin, evaluate the current state of your attic and roof rafters:
- Check for any leaks, damage, or gaps that need to be repaired.
- Measure the spacing and depth of your rafters to determine the amount of insulation required.
- Breathable membrane, timer sarking boards or high vapour resistance roofing felt. If High Vapour Resistance Roofing Felt then leave a minimum 50mm gap. If Breather membrane or Timber Sarking Boards then Sisalwool can be installed to full rafter depth.
If you want to add an extra insulation layer then install counter battens and fit the insulation.

Step 2: Choose Your Insulation Method
There are two primary methods for insulating attic roof rafters:
There are two primary methods for insulating attic roof rafters:
- Loft Insulation Between Rafters: This involves placing insulation directly between the rafters.
For most DIY projects, insulating between loft rafters is the easiest and most practical approach.
Step 3: Gather Materials and Tools
You will need:
- Sisalwool Natural Fibre insulation
- An insulation saw
- Measuring tape
- A vapor control layer (if required)
Step 4: Install the Insulation Between Rafters
- Cut the Insulation: Measure the spaces between your rafters and cut the Sisalwool to fit snugly.
- Fit the Insulation: Press the insulation into the gaps between the rafters. Ensure it is tight against the wood to prevent air gaps.
- Secure the Insulation: Use a staple gun or battens to hold the insulation in place.
Step 5: Add a Vapor Control Layer
In some cases, a vapor control layer is necessary to prevent moisture buildup. Install this layer over the insulation, securing it to the rafters with tape or staples.
Step 6: Finish with Plasterboard or Cladding
To complete the process, cover the insulated rafters with plasterboard or cladding. This not only provides a finished look but also adds an extra layer of thermal efficiency.

Benefits of Using Sisalwool for Rafter Insulation
- Sustainability: Sisalwool is biodegradable and made from natural fibres, reducing your environmental footprint.
- Breathability: It allows moisture to escape, preventing dampness and mold.
- Durability: Sisalwool maintains its shape and performance over time.
- Ease of Use: It’s lightweight and easy to install, making it ideal for DIY projects.
- Cool in summer: Sisalwool has thermal mass which means it absorbs heat and stores it instead of trapping it like PIR so it will keep your roof/attic cooler in the summer months.
