Being a Battleship, ships of the Gleipnir line are thickly armored in a 14 meter thick multilayered plating. Thanks to lessons learned from the Great-War and after that, this layered plating was desgined to be super dense, ductile, moldable and to have finely balanced anti-directed energy and anti-kinetic projectile protection, along with having a decent corrosive resistance and chemical defenses. 
The layers of the armor is as follows. First, the very outer layer is a polarized shell, this helps protect the ship during orbital reentrys and also provides somewhat of a defense against directed energy attacks and thermal energy. 
Next is a paint coating of matte RADAR/LIDAR absorbent polymer-like materials, which renders the vessel nearly invisible on RADAR and distorts LIDAR and laser rangefinders, and a coating of liquid glass resin, which resistant to radiation and deflects UV signals. While this paint doesn't necessarily make the Heavy Battleships prowler, it does provide a tactical advantage that, if far away enough, allows to ship to launch alpha strikes all the while the target is trying to find the Battleship or can't lock onto it.
Underneath this a "skin"-like applicant specifically designed to absorb directed energy, made from a mixture of energy absorbing regenerate non-Newtonian nanomaterials. Forming a superconducting layer, this is highly reactive to directed energy, operating by absorbing the energy and dispersing it across a wider section of the hull, lowering the chances of a breach. 
This allows for better protection against heavy energy weapons like particle cannons, energy projectors, and plasma torpedoes. But this also works well against kinetic projectiles as it can use the absorbed energy against the penetrators, operating by when projectile penetrates the armor, the absorbed energy is dumped into the penetrator, vaporizing it, and greatly diffuses the attack.
Backing this up is a 170 centimeter thick ablative carbon-ceramic shell that is highly reactive to plasma.
Underneath this is the primary defense layer of the ship, a perfect iron whisker armor belt. This is a monocrystalline material enhanced with a multi walled carbon nanotube reinforcement, making it extraordinarily hard, resulting in its ability to shatter kinetic projectiles. To supplement this, the armor belt is sealed in a laminate, made from a carbon fiber-nanolattice infused with diamond dust, that is good at defeating laser and particle weapons. 
Next is the secondary exterior plating of the ship, Titanium-C1 Nanocomposite Battleplates. This uses a design called "Hollow Plate" where, using molecularly enhanced deoxidised titanium-50 grade 38 alpha-beta phase alloy as a substrate, various thin, minute sheets alloys and metals were heavily woven and perfectly bonded together to form a super dense and highly durable hollow plate. And inside was a thin honeycomb of carbon nanotubes, agreggated diamond nanorods, graphene-nanolattice, thermal dissipant nanofibers and tungsten sheets, providing higher kinetic energy absorption and thermal energy resistant. To further enhance the abilities of this plate, intense gravitic fields were used induce super hardening and increased density of the alloys and metals that made up the battleplate. 
Final results are a incredibly light but also highly durable, super hard, hyper dense and thermal resistant plate that is not only superior to older Titanium-A/B battlepling, but also on par with Covenant nanolaminate.
Underneath this is a middlelayer mixture containing light chromium metal foam, silicon disulfide, and vanadium alloys. Arranged in a series of ridges, or "pyramids", this layers serves to catch and split shaped charge jets and kinetic penetrators. 
The final layer before the internal superstructure of the ship is a wall of overlapping ablative carbon-ceramic plates, reinforced with single walled carbon nanotubes, that forced penetrators peirce at a higher angle and improved protection against ballistic and energy projectiles. 
This underlayer is suspended in a elastic polymer that is highly resistant to super-high temperatures and absorbs thermal energy, protecting the iternal superstructure.
As for the superstructure itself, its built on a basis of spars and cross braces arranged in a 'x'-style. These are composed of coltan-tungsten honeycombed durasteel and tightly packed carbon nanotube structural support struts, that, bonded together with non-Newtonian shock absorbers, provide honeycomb-style levels of durability, while being much less heavy and much more cheaper, allowing the ship to lose sustain breaches to nearly all compartments and lose 94.5% of its armor but still remain operational.
Sandwiched in-between the armor plates are additional non-Newtonian shock hardening fluid compounds. When pressed under shear force, the particles of ceramic that are suspended in the fluid form a instantaneous crystalline matrix, hardening in the blink of a eye. Through this, stress from mass impacts can be deflected from the outer, middle, and inner layers, increasing the overall strength of the armor plating. 
For dealing with hull breaches, there is a self sealing fluid layer secured in a airtight space that when exposed to the air through hull breaches expands rapidly and fills the breach while instantly hardening, providing a excellent sealant. This is also backed up by an aerogel layer formed into a Faraday-like cage around the ships internals to prevent relativistic spalling and a stuffed titanium whipple shield that acts as a final protection layer.
This overall armor scheme provided the best protection for UNSCN Battleships while still being economical enough to use on a mass produced scale, and light enough so that the weight wouldn't be much of a hinderence to combat performance.
