A well-insulated roof is crucial for both energy efficiency and the longevity of your home. However, securing that insulation effectively presents a choice: gluing or screwing it into place. Both methods offer advantages and disadvantages, impacting factors like installation speed, cost, thermal performance, and long-term durability. The decision hinges on various considerations, from the type of insulation being used to the specific climate and building regulations. Choosing the wrong method can lead to compromised thermal performance, potential moisture issues, or even structural damage.
This article delves into the specifics of gluing versus screw fixing roof insulation, examining the pros and cons of each approach in detail. We’ll explore suitable materials, proper installation techniques, and common pitfalls to avoid. To guide you through this crucial decision, we'll present a step-by-step guide to installing roof insulation securely, regardless of your chosen fastening method.
Preparation and Safety Guidelines
- Insulation
- Vapor barrier
- Blue tubular fixings
- Screws
- Always prioritize safety: Work with a partner, use appropriate fall protection equipment (harness, lifeline), and never work on a roof in high winds or inclement weather.
- Use appropriate personal protective equipment (PPE): This includes safety glasses, gloves, and respiratory protection, especially when working with adhesives or insulation materials that may release fumes.
- Ensure proper ventilation: Adequate ventilation is crucial when working with adhesives to prevent build-up of harmful fumes and to ensure the adhesive cures properly.
Step-by-Step Instructions
Gluing Insulation
- Applying insulation over vapor barrier with glue.
- Testing glued insulation section.
- Showing examples of problems with gluing insulation, where the foil has separated from the backing.
Gluing Insulation Screw Fixing Method
- Screw fixing method using blue tubular fixings.
- Choosing appropriate screw length based on insulation thickness.
- Ensuring screws are firmly embedded and flush within the blue tubes to prevent bounce and roof damage.
- Inspecting the firmly broken fixings for proper installation.
Screw Fixing Method Comparing Methods: Advantages & Disadvantages
- Demonstrating issues with insufficient screw head size and heat transfer.
- Highlighting the importance of firmly broken fixings over glue for better roof security.
- Analyzing a failed GRP roof installation with deteriorating nails, illustrating the risk of solid fasteners.

Tips
- Use screws of appropriate length for the insulation thickness.
- Ensure screws sit snugly within the blue tubes to avoid bounce and damage.
- Utilize firmly broken fixings for superior roof security and to avoid heat transfer problems.
- Avoid relying solely on glue for insulation attachment.
- Opt for thermal fixings with slight movement tolerance to prevent damage from pressure or movement.
