Why use a Gridboard for underfloor heating?

Using a gridboard like Tekwarm UFH Gridboard EPS100 for underfloor heating significantly enhances the system's efficiency by ensuring precise pipe placement and uniform heat distribution. The inclusion of EPS insulation not only optimises the heating system's performance and energy usage but also helps to direct heat upwards into the room, ensuring that warmth is effectively delivered where it's most needed. This makes Tekwarm UFH Gridboard EPS100 an essential component for maximising the effectiveness of underfloor heating installations.

Is Tekwarm UFH Gridboard EPS100 suitable for water or electric underfloor heating systems?

Tekwarm UFH Gridboard EPS100 is designed primarily for water-based underfloor heating systems. The board's structure allows for the secure placement and retention of water pipes, enhancing the system's thermal conductivity.

Can screed be applied directly over Tekwarm UFH Gridboard EPS100?

Yes, screed can be applied directly over the Tekwarm UFH Gridboard EPS100. The board’s design, featuring a laminated polypropylene layer, ensures compatibility with screed applications, providing a solid and even surface for final floor finishes.

What thickness of Tekwarm UFH Gridboard EPS100 is recommended for my project?

The recommended thickness for your project depends on the specific insulation requirements, space constraints and the floor structure. Commonly, thicknesses range from 25mm for minimal elevation and increased thermal efficiency, up to 100mm for maximum insulation in areas where height adjustment is not a concern.

What advantages does the laminated gridded layer offer?

The laminated gridded layer on Tekwarm UFH Gridboard EPS100 offers several advantages, including facilitating accurate pipe placement, enhancing pipe clip retention, and providing a guide for systematic installation. This layer also contributes to the overall durability and moisture resistance of the board.

You have a PIR version of the Tekwarm Gridboard available, when should I choose EPS Gridboard, and when should I choose PIR Gridboard?

The choice between EPS (Expanded Polystyrene) and PIR (Polyisocyanurate) Gridboards depends on your project’s specific insulation requirements and budget considerations.

EPS gridboards are lightweight, cost-effective, and offer good insulation properties, making them suitable for projects where budget constraints are a priority without significantly compromising on insulation quality. They are ideal for standard underfloor heating applications that require efficient heat distribution and moderate insulation values.

On the other hand, PIR gridboards, while more expensive, provide much higher insulation values due to their superior thermal efficiency. This allows for the use of thinner boards to achieve higher specifications, making them an excellent choice for projects demanding the highest level of thermal efficiency within minimal installation heights. PIR gridboards are particularly beneficial in spaces where floor height is limited, or where enhanced insulation is required to meet stricter building regulations or to achieve greater energy savings.

In summary, opt for EPS gridboards for cost-effective, reliable insulation in general underfloor heating applications. Choose PIR gridboards when your project demands superior insulation performance, especially in areas with space constraints or where achieving higher energy efficiency standards is a priority.

Can Tekwarm Gridboard be used for retrofitting existing floors?

Yes, Tekwarm UFH Gridboard EPS100 is suitable for retrofitting existing floors. Its lightweight and easy-to-cut material allows for straightforward installation in renovation projects, making it an ideal choice for upgrading the thermal and acoustic performance of existing floors.

How durable is Tekwarm UFH Gridboard EPS100?

Tekwarm UFH Gridboard EPS100 is designed to last the life of the building without any loss in thermal performance. It is rot-proof and resistant to the growth of mould and fungi, ensuring long-term durability and maintaining the integrity of the underfloor heating system.

Is the EPS insulation environmentally friendly?

Yes, the Expanded Polystyrene (EPS) insulation used in Tekwarm UFH Gridboard EPS100 is environmentally friendly. It is manufactured from CFC and HCFC-free materials, has a Global Warming Potential (GWP) of zero, and a low Ozone Depletion Potential (ODP). Additionally, EPS is 100% recyclable, contributing to sustainable building practices.
