Fixings & Adhesive

Insulation fixings and adhesives are critical to securing rigid insulation and wood wool boards. At bio space, we supply mechanically tested fixings and high-performance adhesives designed for breathable systems, ensuring strong pull-out values, consistent bond strength and minimal thermal bridging across masonry and timber substrates. Correct specification helps maintain airtightness and moisture balance. Our range is suited to natural insulation systems and wood wool boards with bulk supply available for trade and larger projects.

Frequently asked questions
What standards should insulation and wood wool fixings meet?

Insulation and wood wool board fixings should comply with ETAs and ETAG 014 or EAD guidelines for ETICS. They must provide sufficient pull-out strength, load capacity, and resistance to corrosion and thermal movement. CE marking and compliance with national regulations ensure safety and long-term performance.
What pull-out strength should I expect from insulation fixings?

Pull-out values vary by substrate, but typical performance in masonry ranges from 0.6 kN to 1.5 kN+. Site testing is often required to confirm suitability, particularly on refurbishment or mixed substrates. Correct fixing density is just as important as individual strength.
Do insulation adhesives affect thermal performance?

Yes. Poor adhesive coverage can create voids that lead to cold bridging and reduced system efficiency. Full or controlled coverage methods are used to maintain consistent contact and support declared U-values.
Are these suitable for breathable insulation systems?

When correctly specified, yes. Fixings and adhesives used with natural insulations must allow vapour movement through the wall build-up. This supports moisture balance and reduces condensation risk in breathable construction.
Do fixings create thermal bridging?

They can if poorly specified. Many modern fixings are designed to reduce conductivity or be recessed into insulation layers to limit heat loss, which is important in high-performance builds.
Can insulation fixings be used with all insulation types?

No. Fixings must be compatible with the insulation material, whether that is wood fibre, cork, or wood wool boards. And substrate is also an important factor.
