When it comes to improving home energy efficiency, most people think of windows, wall insulation, or underfloor heating. But they often forget about one of the most important elements — the entry door. Up to 15–20% of heat can be lost through an outdated, poorly sealed, or warped door.

Modern entry doors are not just about security or aesthetics — they play a crucial role in keeping your home warm and protected from the cold.

## How New Entry Doors Help Preserve Heat

Today’s entry doors are engineered with thermal efficiency in mind. Here’s what makes them effective:

- Metal or composite panels with thermal breaks — prevent cold penetration
- Foam-filled core (mineral wool or polyurethane) — provides insulation
- Magnetic or multi-contour seals — block drafts and cold air
- High-quality compression systems — ensure tight closure around the frame
- Energy-efficient glass inserts (if present) — double or triple glazed

## The Role of Door Hardware in Heat Retention

People often underestimate the importance of hardware — locks, hinges, seals, closers. But these components determine:

- How tightly the door closes
- Whether it will stay aligned and functional over time
- If the insulation and sealing will hold up after years of use

High-quality hardware = consistent thermal protection and long-term reliability.

## Key Benefits of Replacing Old Entry Doors

- Lower heating costs — thanks to reduced heat loss
- No more drafts — no need for extra rugs or door snakes
- Comfortable entryway — even in winter, no cold air leaking in
- Better noise insulation — reduced outside noise and dust
- Improved security and curb appeal — modern doors are stronger and more stylish

## What to Look for in Energy-Efficient Entry Doors

1. Panel thickness — 70 mm or more
2. Number of sealing contours — ideally 2 or 3
3. Thermal break in the frame and panel
4. Certified high-performance hardware
5. Option to install closers and drop seals
6. Manufacturer warranty
