Foam insulation tape is a versatile and reliable solution that seals gaps, stops drafts, and improves energy efficiency in both homes and buildings. Easy to install, it comes in a variety of sizes and types with single-sided self-adhesive, to suit different uses and needs. By choosing a high-quality product like TruFit™, you ensure a strong, long-lasting seal that enhances comfort and reduces energy costs. In this guide, we’ll explore the benefits of foam insulation tape and the wide variety of advantages it can make in your insulation efforts.
Understanding Foam Insulation Tape
Foam insulation tape is a versatile product used for sealing gaps, especially around windows and doors, to reduce drafts and prevent air leakage. It’s popular across residential, construction, and automotive industries, including the construction industry, due to its flexibility and strong sealing properties. Among the different types, expanding foam tape is a top choice for energy savings, thanks to its ability to create an airtight barrier that stops air from escaping and entering.
Expanding foam tape typically comes pre-compressed with a single-sided adhesive, relying on compression to enhance its sealing properties and vibration absorption. Single sided foam tape, once applied, expands to fill gaps, making it ideal for surfaces that aren’t perfectly even. This quality makes single sided foam tape a smart and easy option to improve your home’s energy efficiency.
Among its materials, polyurethane and EPDM are common for their compression recovery, while closed-cell PE foam offers moisture resistance. These variants make foam insulation tape suitable for both external and internal sealing, vibration absorption, and thermal insulation projects.
Why Choose TruFit™ for Your Windows?
For superior window insulation, TruFit™ foam insulation tape offers an efficient solution that significantly boosts energy performance. It bonds securely to multiple window frame materials—including aluminium, timber, and uPVC—providing a durable, airtight seal that eliminates drafts and reduces heat loss.
Whether you’re sealing newly installed windows or upgrading older ones, TruFit™ ensures lasting comfort, cost-effective insulation, and cleaner finishes compared to silicone or expanding foam methods. Its pre-compressed design expands automatically once applied, filling any irregularities around your window perimeter to create a reliable thermal and acoustic barrier.
Key Features That Set TruFit™ Apart
TruFit™ stands out due to its combination of advanced materials and energy-efficient performance properties:
- Strong Acrylic Adhesive: Forms a reliable bond on multiple surfaces and maintains its grip through temperature changes.
- Expanding Polyurethane Core: Seals completely when expanded, ensuring a fine balance between airtightness and controlled vapour release.
- Weatherproof and UV Resistant: Suitable for interior or exterior window perimeter joints, standing up to harsh UK conditions.
- Sound and Moisture Blocking: Minimises external noise penetration and prevents water ingress, helping maintain both comfort and structure longevity.
- Intelligent Vapour Diffusion: Follows the “inside tighter than outside” principle—allowing moisture to escape externally while keeping interiors dry.
These attributes make TruFit™ a trusted solution for installers seeking consistent energy efficiency results for homeowners.
How TruFit™ Enhances Window Insulation
As an air and moisture barrier, TruFit™ foam insulation tape closes micro gaps and cracks that commonly cause heat loss through window frames. By maintaining a continuous seal, it reduces temperature exchange between indoor and outdoor environments.
This airtight closure means heating systems no longer compensate for escaping warm air or incoming cold drafts, cutting annual energy usage and costs. Its thermal conductivity of approximately 0.048 W/m·K demonstrates insulation comparable to high-grade materials used in passive house construction.
Additionally, TruFit™ helps prevent condensation, mould, and rot around frame edges. The foam’s acoustic dampening qualities also lower external noise for a quieter, more energy-efficient indoor environment.
Benefits of Foam Insulation Tape
Foam insulation tape offers comprehensive benefits that make it one of the most practical, multipurpose insulation and sealing products for homes and professional installations:
- Energy Efficiency and Cost Savings
By creating a continuous, airtight seal, foam insulation tape reduces heat loss through window perimeters by up to 33%. This results in improved thermal efficiency and measurable energy savings throughout the year. - Simple, Mess-Free Installation
Unlike silicone or spray foam, expanding foam tape provides clean application and instant adhesion. There’s no curing time or mess, making it suitable for all weather conditions and quick retrofitting. - Noise Reduction and Comfort Enhancement
The foam’s density absorbs sound waves, creating a significant noise reduction in busy or urban areas. - Weather and Moisture Resistance
High-quality products like TruFit™ protect against rain, condensation, and humidity. This helps prevent costly long-term issues like mould and frame deterioration. - Durability and Longevity
TruFit™ retains elasticity and sealing performance for over a decade, resisting UV exposure and temperature fluctuations.
Common Applications
Foam insulation tape is widely used across industries due to its thermal, acoustic, and sealing performance:
- Home Windows and Doors: Airtight seals around frame perimeters, preventing drafts and heat loss.
- Construction and Glazing Projects: Gap sealing during window, façade, or conservatory installations.
- External Wall Insulation (EWI) Systems: Prevents cold bridging by sealing junctions and openings.
- HVAC Systems: Used to prevent air leaks and improve energy use efficiency.
- Automotive and Marine: Damps vibration and seals joints between metal or glass panels.
This versatility makes foam insulation tape an essential component in energy-efficient design and refurbishment.
Installation Guide for Foam Insulation Tape
Installing foam insulation tape, like TruFit™, is simple and requires proper packaging for protection. You can do it easily, even if you don’t have much experience with DIY tasks. First, make sure the window surfaces are clean and dry. There shouldn’t be any dirt or dust. This helps the tape stick better.
After that, measure and cut the foam tape to the right length. It should fit tightly in the window frame. This guide will help you with each step.
Installation Guide for TruFit™ Foam Insulation Tape
Installing TruFit™ foam insulation tape is straightforward, even for those new to DIY. Here’s a simple installation guide to ensure the best results.
Preparing Your Windows for Installation
Start by thoroughly cleaning the window frame where the tape will be applied. Use a gentle cleaner to remove any dirt, dust, or residue. If needed, use a scraper for stubborn grime. Once clean, make sure the surfaces are completely dry to help the tape adhere properly. Carefully measure your window frames to avoid waste when cutting the tape.
Step-by-Step Installation Process
Once your windows are prepped, follow these steps to install TruFit™ foam insulation tape:
- Peel back a small section of the tape’s backing paper to expose the adhesive.
- Align the exposed adhesive edge with the start of your window frame.
- Gradually press the tape onto the frame, peeling back the backing paper as you go.
- Apply firm, even pressure along the tape to ensure a secure seal.
Repeat these steps around each section of your window frame to create a continuous, airtight seal. This simple installation can significantly improve your window insulation and energy efficiency.
