Aluplast Ideal 7000 vs Ideal 4000: comparison

Aluplast Ideal 7000 vs Ideal 4000: comparison

This article compares two widely used Aluplast profile series — Ideal 7000 and Ideal 4000. We'll examine structural differences, thermal and acoustic performance, glazing options, hardware compatibility, finishes, and which series offers better value depending on project requirements.

Quick overview

  • Ideal 7000 — a 6-chamber profile with deeper section, designed for improved thermal insulation and larger glazing units.
  • Ideal 4000 — a more compact 3–4-chamber profile, budget-friendly and suitable for standard applications.

Profile construction

Ideal 7000 features a wider and multi-chamber profile providing better rigidity and reduced heat loss. The typical frame width is around 70 mm, which allows installation of two- or three-chamber insulating glass units with enhanced properties.

Ideal 4000 is narrower (about 60 mm) with fewer chambers. It is lighter and usually less expensive in production and installation.

Thermal performance and energy efficiency

  • Ideal 7000: superior thermal insulation due to more chambers and the capacity for thicker IGUs. Ideal for colder climates and energy-efficient renovations.
  • Ideal 4000: adequate thermal performance for moderate climates and heated buildings.

Actual U-values depend on the chosen glazing and seals, but in practical setups Ideal 7000 typically delivers noticeably better results.

Sound insulation

The greater profile depth and heavier glass options in Ideal 7000 result in improved acoustic insulation. Choose it for busy streets or noisy environments.

Hardware and functionality

Both systems are compatible with modern hardware: tilt-and-turn mechanisms, micro-vents, multipoint locks, and child safety fittings. Ideal 7000 better supports heavier sashes and larger glazing units without loss of stiffness.

Glazing and finishes

Ideal 7000 enables installation of two- or three-chamber IGUs, low-E coatings, argon fill, and multifunctional glazing. Color options and foils are available for both series: white, woodgrain, and textured finishes.

Ideal 4000 is commonly used with simpler double glazing. Both support a wide range of laminations.

Installation and maintenance

Professional installation is required for both. Ideal 7000 may demand more precise installation due to weight and dimensional characteristics, but the outcome is better long-term performance. Maintenance is standard: cleaning seals, hardware adjustment, and drainage checks.

Price and value

Ideal 7000 is more expensive in material and installation but can be cost-effective long-term through heating savings. Ideal 4000 is best for budget-limited projects requiring standard performance.

Recommendations

  • Choose Ideal 7000 for maximum energy efficiency, superior sound insulation, and when planning for three-chamber IGUs.
  • Choose Ideal 4000 for typical apartments where budget and standard performance are primary concerns.

Frequently Asked Questions (FAQ)

1. What is the main difference between Ideal 7000 and 4000?

The main difference is the number of chambers and profile width. Ideal 7000 has more chambers and larger depth, which translates into better thermal and acoustic properties.

2. How much more expensive is Ideal 7000?

Prices vary by configuration, but generally Ideal 7000 costs about 15–35% more than Ideal 4000 under comparable options.

3. Which profile is better for a detached house?

For detached houses, especially in cold regions, Ideal 7000 is recommended due to improved insulation.

4. Can I use energy-saving glass in 4000?

Yes, but the overall efficiency gain is limited by the profile's structure and maximum glazing thickness.

5. Is Ideal 7000 harder to install?

Installation requires attention to detail and handling due to higher weight, but with qualified installers it is as straightforward as 4000.

6. Which profile is easier to maintain?

Both are similar in maintenance needs. Reliability depends more on hardware quality and installation than on profile series.

7. Is it worth upgrading to 7000 in a centrally heated apartment?

If you prioritize reduced heat loss and better noise control, yes. If the budget is tight, 4000 can be sufficient.

8. What should I check when buying?

Verify the actual IGU configuration, quality of seals, hardware brand, and correct installation details for thermal bridging and drainage.
