When it comes to choosing the perfect patio doors for your home, two key factors should be at the top of your list: energy efficiency and security. Not only do these elements enhance the comfort and safety of your living space, but they also contribute to long-term savings and peace of mind. In this blog, we’ll guide you through what to look for in energy-efficient and secure patio doors, with a spotlight on top brands like Liniar and VEKA.

Energy Efficiency

Thermal Insulation

The primary goal of energy-efficient patio doors is to minimise heat loss. Look for doors with high-quality insulation materials. Liniar’s multi-chambered uPVC profile, for example, provides excellent thermal insulation. This design traps pockets of air within the frame, reducing heat transfer and keeping your home warmer in winter and cooler in summer.

Low-E Glass

Low-emissivity (Low-E) glass is a must-have for energy-efficient patio doors. This type of glass has a special coating that reflects heat back into your home, reducing heat loss through the glass. VEKA offers a range of doors with Low-E glass, ensuring that your home remains comfortable while lowering your energy bills.

Double or Triple Glazing

Double glazing is standard for many patio doors, but triple glazing offers even greater energy efficiency. Triple-glazed doors provide an additional layer of insulation, making them ideal for homes in colder climates. Double glazing brands like Liniar and VEKA offer double and triple-glazed options to suit your needs.

Weather Seals

Effective weather seals are crucial to prevent drafts and water ingress. Ensure that the patio doors you choose have high-quality seals that remain effective over time. Liniar doors feature patented double-action gaskets that maintain a tight seal, even under extreme weather conditions.

Security Features

Multi-Point Locking Systems

Security is a top priority for any patio door. Multi-point locking systems, which lock the door at multiple points along the frame, provide superior protection against forced entry. VEKA’s patio doors come equipped with robust multi-point locking systems, ensuring your home is secure.

Toughened or Laminated Glass

The type of glass used in patio doors also plays a significant role in security. Toughened or laminated glass is much harder to break than standard glass. Laminated glass, in particular, holds together when shattered, providing an additional layer of security. Both Liniar and VEKA offer patio doors with toughened or laminated glass options.

Reinforced Frames

A strong frame is essential for a secure patio door. Look for frames that are reinforced with steel or other durable materials. VEKA’s reinforced uPVC frames offer excellent strength and resistance to impact, making them a reliable choice for security-conscious homeowners.

Anti-Lift Devices

Anti-lift devices prevent intruders from lifting the door out of its frame. Ensure your patio doors are equipped with these devices for added security. Liniar’s patio doors include anti-lift mechanisms as standard, providing peace of mind for homeowners.


Choosing the right patio doors involves careful consideration of both energy efficiency and security. Brands like Liniar and VEKA offer excellent options that meet these critical criteria. By investing in high-quality, energy-efficient, and secure patio doors, you can enhance the comfort, safety, and value of your home.
