Insulated Plasterboard Fixings

ISF18A insulated plasterboard fixings are a one piece metal fixing which has a dished head. These insulation fixings are for use in installing Insulated plasterboard panels. Insulated drywall fixings are essential even when insulated plasterboard is being dot and dabbed to the walls. Installing these fixings in addition to drywall adhesive assists in the prevention of boards falling from the walls when the building is on fire. The ISF18A has a self tapping hardened steel shank which helps it cut into various masonry profiles.

When installing insulated wallboard fixings you should use 12 per board unless you are using drywall adhesive in which case you would then only use 3 per board. The design of the shank has an area that is only 25% of a similar solid shaft fixing which reduces the risk of thermal bridging. Another feature of this high spec insulation fixing is the dished head which when installed correctly can be filled with filler or plastered over. This is very important when the boards are to be decorated as this makes the fixing invisible.

ISF18A plasterboard fixings can be fixed directly into aircrete blocks although when fixing into concrete a 5 mm pilot hole must be drilled first. Essentially all types of insulated plasterboard can be fixed using this type of fireproof  wallboard fixing.

Jacqueline Jelley,

After days of trying to order some Rockwool from suppliers who never got back to me or quoted silly prices, my enquiry to BMD was answered in minutes politely and with clear knowledge of the products and delivery arranged on the phone all at a great price. Top marks for A1 service and product knowledge.

Very happy with the service we received. Fantastic product at a fantastic price. Cant recommend Jason and the team highly enough. Ordered during Covid-19 when everything was slightly crazy and delayed and Jason called and said they had a lorry in our area so could deliver the very next day! Thank you guys for 5 star service, will be back in the future . All the best, Lacey. Travellers Finds Ltd

As a small building company we find that BMD will equal or beat our trade depot plus we get free delivery too !!, Also we can get everything in one order and being able to talk to an actual person rather than clicking on a website means we get the service we want. saves time and money whats not to like ? :-)
