22 Aug What makes Palladio doors weatherproof and airtight?

If you want a front door that blocks wind, rain, and cold while keeping heat inside, Palladio composite doors are a good choice. Every part of the Palladio door, from the main slab to the threshold, is made for a tight seal and long-lasting weather protection.

Below are the main reasons Palladio doors are among the most weatherproof and energy-efficient composite doors in Cardiff.

Twin seals with a double rebate

Most doors only have one rebate where the edge meets the frame. Palladio uses two rebates, along with two continuous gaskets. This creates two barriers against draughts and water, which the company calls “excellent draught proofing.” 

65 mm monocoque slab

The centre of every Palladio door is a 65 mm thick fibreglass-reinforced monocoque shell. Unlike foam-core doors, a monocoque is one solid piece.

Because it is one strong shell, it does not bend or warp the way other doors can over time. This is how the seals stay tight all the way around, and that keeps the door airtight year after year.

Multi-point compression lock

The locking system on a Palladio door is made to seal as well as secure. It uses two hooks, two shootbolts, four rollers, and a deadlatch. These pull the door firmly into the gaskets from every angle, which blocks draughts and keeps rain from getting in.

Triple glazing with warm-edge spacers

When the design includes glass panels, Palladio uses triple glazing. They also use warm-edge spacers and internal glazing beads. This keeps the edges of the glass warmer, which in turn reduces condensation forming in cold weather.

It also adds another airtight barrier to the door. On top of that, the warm-edge technology helps the door keep a better energy rating.

Strong thermal performance

U-values measure how much heat a door lets escape. The lower the number, the better the insulation. Palladio reports:

• The door leaf can be as low as 0.205 W/m²K.
• A solid door with the frame comes in at about 0.85 W/m²K.
• Even a glazed door with the frame is around 0.98 W/m²K.

These numbers are much lower than what you see with many other doors, which means your home keeps more heat inside and your heating bills stay lower.

Frames and thresholds built to last

The frames on Palladio doors are made from 70 mm PVCu with steel reinforcement for extra stability. At the bottom of the door, Palladio suggests using either a PVC threshold or the Stormguard Plus rebated threshold for the best seal. This part is important because floor-level gaps are where many doors fail over time.
