Glass Wool & Ceiling Fixings - Buy Genuine Gyproc Screws, Plugs, Cleats & Jointing Compound Online

A false ceiling's finished, seamless look depends entirely on the parts you never see once it is painted - the screws, plugs, cleats and jointing compound that fix and hold everything together. Skimp on these, or use the wrong one in the wrong place, and the ceiling sags, the joints crack, or the whole assembly comes loose from the slab it hangs from. At Fixxly, this range is 100% genuine Gyproc: drywall screws, metal-to-metal self-drilling screws, GI rawl plugs, a GI soffit cleat, fiber glass jointing tape and Easi-Fill jointing compound. This guide covers each product, the role it plays in a false ceiling build, and the order they actually go in.

Insulation

Glass wool and fiber glass wool

Glass wool, or fiber glass wool, is laid above a false ceiling to slow heat transfer from a hot roof and absorb sound, cutting noise transfer between floors - the insulation layer that makes a false ceiling genuinely effective rather than just decorative. A false ceiling built without insulation captures only part of the benefit a false ceiling can offer; adding glass wool is what makes it thermally and acoustically effective, not just visually finished. This is a different product from the fiber glass tape used for jointing, despite the similar name.

Screws

Gyproc 25mm drywall screw

A black phosphate drywall screw, supplied in a box of 1000, built to fix gypsum board to the metal frame without cracking the paper face - this is what most people mean by gypsum screw.

Gyproc 4.2x13mm metal-to-metal self-drilling screw

A different product for a different job, supplied in a box of 500: joining sections of the metal framework itself rather than fixing board to frame. Using the wrong screw for either job is a common, avoidable cause of a joint that works loose or a board that cracks at the fixing point.

Suspension and anchoring hardware

Gyproc GI-Rawl Plug 8x45mm

Supplied in a box of 100, this anchors the ceiling's suspension framework into a solid masonry or concrete slab above - the fixing that holds the entire ceiling's weight at its structural point of contact. Getting this fixing right matters more than almost any other single component in the build, since every other part of the ceiling ultimately hangs from it.

Gyproc GI-Soffit Cleat

Supplied in a box of 50, this is the bracket that suspends the ceiling framework from the slab, setting the level the whole ceiling hangs from - one of the first components fixed when building a false ceiling. Correctly spaced, secure cleats are what prevent a ceiling from sagging between fixing points over time.

Jointing materials

Gyproc Easi-Fill 90 Jointing Compound

Supplied in a 20kg pack, this fills and smooths the taped joint between boards so it disappears into one continuous, seamless surface once painted.

Gyproc Fiber Glass Tape

A 90-metre self-adhesive joint tape that reinforces the joint before compound goes on, preventing it from cracking as the building settles - skipping the tape and relying on compound alone is a common shortcut that shows up as a hairline crack along the joint within a year or two.

Building a ceiling in the right order

• Fix the GI-soffit cleat to the slab first, setting the level the ceiling hangs from.
• Anchor the framework with GI-rawl plugs where it meets masonry or concrete.
• Join framework sections with metal-to-metal self-drilling screws.
• Fix gypsum board to the frame with 25mm drywall screws.
• Reinforce board joints with fiber glass tape before applying Easi-Fill jointing compound.
• Add glass wool insulation above the ceiling for thermal and acoustic performance.

Getting the joint finish right

The seamless look of a good gypsum ceiling comes entirely from how the joints are finished. After boards are fixed to the framework, the fiber glass tape goes over the joint first, then Easi-Fill compound is applied in thin coats and smoothed, often needing two or three passes with light sanding between coats to fully disappear the joint line. Rushing this step - applying compound too thickly in one pass, or skipping the tape - is the most common reason a finished ceiling still shows a faint line at every board joint once painted.

Frequently asked questions

Does Fixxly stock genuine Gyproc products?

Yes - every screw, plug, cleat, tape and jointing compound in this range on Fixxly is genuine Gyproc, India's leading false ceiling and gypsum board manufacturer.

What is the difference between glass wool and fiber glass tape?

Glass wool is a loose insulation material laid above a ceiling for thermal and acoustic performance, while fiber glass tape is a reinforcing strip used inside the joint between two boards before jointing compound is applied. They share a material name but serve entirely different purposes.

What screws are used for gypsum board?

The Gyproc 25mm drywall screw fixes gypsum board to the metal frame without cracking the paper face, while a separate metal-to-metal self-drilling screw joins sections of the framework itself.

What does a GI-soffit cleat do?

A soffit cleat suspends the ceiling's metal framework from the slab above, setting the level the whole ceiling hangs from, and is one of the first components fixed when building a false ceiling.

Why can I still see a line at my ceiling joints after painting?

This usually means the jointing compound was applied too thickly in one pass, or the fiber glass tape was skipped. Two or three thin coats with light sanding between each, over a taped joint, is what gives a fully seamless finish.

Why is the GI-rawl plug so important to get right?

The rawl plug anchors the entire suspension framework into the slab above, meaning every other part of the ceiling ultimately hangs from this single fixing point - a poorly seated plug here risks the whole ceiling section, not just a local fault.
